The Boston Red Sox and Miami Marlins have reportedly made a deal, per a tweet from The Athletic's Ken Rosenthal on Monday morning. According to Rosenthal's tweet, Boston is trading reliever Matt Barnes to Miami for fellow relief pitcher Richard Bleier. Barnes pitched to a 4.31 ERA, a 3.87 FIP, 34 strikeouts, and 21 walks in 39.2 innings for Boston last season while adding eight saves and four holds. Bleier, meanwhile, turned in a 3.55 ERA and a 3.27 FIP in 50.2 innings for the Marlins, while adding 32 strikeouts, 10 walks, seven holds and a save. Of the duo, Barnes likely has more potential for save opportunities this coming season in Miami than Bleier does in Boston given Kenley Jansen's presence at the back end of the Red Sox bullpen.

Relief pitcher Darren O'Day announced on Monday he's retiring from the league in a tweet. O'Day made his Major League debut with the Los Angeles Angels in 2008 and has appeared in every Major League season since. The 40-year-old made 644 appearances over the years, pitching for Los Angeles, the New York Mets, Texas, Baltimore, Atlanta, and the New York Yankees. He most recently appeared in 28 games for Atlanta in 2022, pitching to a 4.15 ERA and a 4.04 FIP in 21.2 innings of work while logging 26 strikeouts compared to 10 walks. For his career, the 40-year-old owns a 2.59 and a 3.48 FIP in 609-lifetime innings at the Major League level. He struck out 9.41 batters per nine frames while allowing just 2.54 walks per nine innings.

Texas Rangers general manager Chris Young isn't ruling out the possibility that left-hander Brock Burke could close some games for the team in 2023. Burke made his major-league debut as a starter for the Rangers in 2019 and had a 7.43 ERA (6.55 FIP) and 1.54 WHIP in his first six starts. But he was much better as a reliever in his return to the majors in 2022, going 7-5 with a sharp 1.97 ERA (3.29 FIP), 1.06 WHIP and 27.4 percent strikeout rate in 82 1/3 relief innings over 52 appearances. The 26-year-old gained some velocity with the transition to a relief role and could be in line for some high-leverage work at the back end of Texas' bullpen alongside fellow setup man Jonathan Hernandez and Jose Leclerc. Burke probably isn't worth a draft pick in shallow mixed leagues, but he should certainly be on the radar of saves speculators and deep holds leagues in 2023.

After two seasons with the Boston Red Sox, right-hander Hirokazu Sawamura signed with the Chiba Lotte Marines of Nippon Professional Baseball on Saturday to return to Japan. He appeared in 104 games for Boston from 2021-22 and had a 3.39 ERA (4.59 FIP), 1.44 WHIP, 101 strikeouts and 59 walks in 103 2/3 innings pitched over 104 relief appearances. The 34-year-old could come back to the States and sign with a major-league team if he impresses back in Japan, but it's probably unlikely. Sawamura had a 3.73 ERA (4.16 FIP), 1.42 WHIP and 18.1 percent strikeout rate in 50 2/3 innings for Boston last season.

The Baltimore Orioles signed free-agent third baseman Curtis Terry to a minor-league deal on Friday. Terry made his major-league debut with the Texas Rangers in 2021 and went 4-for-45 with no homers, one RBI, three runs scored and 15 strikeouts in 48 plate appearances over only 13 games played. The 26-year-old spent the 2022 campaign with the Minnesota Twins' Triple-A affiliate in St. Paul and slashed .250/.348/.429 with a .777 OPS, 10 home runs, 32 RBI and 41 runs scored in 80 games. Terry will provide the Orioles with depth at the hot corner this year, but he'll likely begin the regular season in the minor leagues.

Free-agent right-hander Ian Kennedy announced in his official Instagram page on Friday that he has agreed to an undisclosed deal with the Texas Rangers. Kennedy hit the open market this offseason when the Arizona Diamondbacks declined his $4 million option for the 2023 season. The 38-year-old reliever struggled in the desert last year with a 5.36 ERA (5.58 FIP), 1.57 WHIP, 10 saves and weak 19.0 percent strikeout rate in 50 1/3 relief innings over 57 appearances out of the bullpen. The 16-year veteran was with the Rangers for 32 appearances in 2021 and pitched well with a 2.51 ERA (3.66 FIP), 1.05 WHIP and 16 saves, but it would be a surprise if he gets many save chances this year with Texas with Jose Leclerc locked in as the primary closer.

The Baltimore Orioles designated left-hander Darwinzon Hernandez for assignment on Thursday to make room on the 40-man roster for left-hander Cole Irvin, who was acquired in a trade with the Oakland Athletics. Baltimore landed Hernandez in a trade with the Boston Red Sox earlier this offseason, but the 26-year-old southpaw could be on the move yet again. He only tossed 6 2/3 relief innings for Boston in 2022 and was beat up to the tune of 17 runs (16 earned) on 14 hits (four home runs allowed) while walking eight and striking out nine. The Venezuelan reliever has interesting stuff but has yet to put it all together at the big-league level in four years with the Red Sox. If Hernandez clears waivers, he could return to Baltimore.

New York Yankees relief pitcher Michael King (elbow) said that he expects to be ready for Opening Day after missing the final two-plus months of last season with a fractured right elbow. If healthy in 2023, King will likely be used as a multi-inning stopper in the Yankees' bullpen in the later innings in front of closer Clay Holmes. Before he was hurt in 2022, King was excellent for the Yanks, going 6-3 with a 2.29 ERA (2.23 FIP), 1.00 WHIP, his first career save, 66 strikeouts and 16 walks in 51 relief innings over a career-high 34 relief appearances. The 27-year-old right-hander may be eased in initially, but he should carry plenty of value in fantasy leagues that reward holds.

Seattle Mariners relief pitchers Paul Sewald (elbow, heel) and Andres Munoz (foot), who both had surgeries this offseason, might not see much action early in spring training. However, relievers don't usually need much work in the spring to get ready, and they should both be fine for Opening Day. Both pitchers are a big part of the back end of Seattle's bullpen heading into 2023, with Sewald currently slated to enter the year as the primary closer. Sewald was great in his second year with the M's, posting a career-best 2.67 ERA (3.88 FIP), career-high 20 saves, 0.77 WHIP and 72 strikeouts in 64 relief innings. Munoz was just as good with a 2.49 ERA (2.04 FIP), four saves, 0.89 WHIP and 96 K's in 65 innings out of the bullpen.

The Tampa Bay Rays signed left-hander Jeffrey Springs to a four-year, $31 million contract extension on Wednesday. If the Rays pick up his 2027 option, Springs can make up to as much as $65.75 million while also earning his performance bonuses. The 30-year-old southpaw had a career-best 2.46 ERA (3.04 FIP), 1.07 WHIP and 26.2 percent strikeout rate in a career-high 135 1/3 innings covering 33 appearances (25 starts) in his second year with the Rays and fifth in the major leagues. Given the extension, it's clear the Rays plan to use Springs in their rotation in the coming seasons after he entered the 2022 campaign with just two big-league starts in four seasons. Even in the tough American League East, Springs will have some appeal in the later rounds of fantasy drafts as rotation depth.

The Boston Red Sox officially designated relief pitcher Matt Barnes for assignment on Tuesday, per the Athletic's Jen McCaffrey. The move was made to make room for recently-signed outfielder Adam Duvall. The 32-year-old righty did see some high-leverage situations over the course of the 2022 season but ended with an 0-4 record, eight of 10 save opportunities converted, and four holds to go with a 4.31 ERA, 1.44 WHIP, and 19.3% strikeout rate. He also missed time in the middle of the season with right shoulder inflammation. Barnes did earn 24 saves for the Red Sox in 2021, so he may be able to find a high-leverage spot with another team.

Free-agent left-hander Devin Smeltzer agreed to a one-year split deal with the Miami Marlins on Tuesday. He will make $1 million if he's in the majors and will receive an invitation to major-league spring training, according to sources. The 27-year-old southpaw reliever had a 3.71 ERA (5.23 FIP), 1.22 WHIP and career-low 13.9 percent strikeout rate in a career-high 70 1/3 innings pitched over 15 appearances (12 starts) for the Minnesota Twins last year. There is more opportunity in Miami's starting rotation with Pablo Lopez now in Minnesota, but Smeltzer will likely open the 2023 season as a long man in Miami's bullpen if he makes the Opening Day roster out of spring training.

MLB.com's Bryan Hoch reported Monday that New York Yankees outfielder Aaron Hicks will likely be the team's starting left fielder for the 2023 season. General manager Brian Cashman said of Hicks, "I suspect he will be the guy that emerges, because he's still really talented and everything's there." The 33-year-old has spent much of his career with the Yankees in a platoon role and slashed an uninspiring .216/.330/.313with eight home runs, 40 RBI, and 10 stolen bases in 453 plate appearances in 2022. While the Yankees do have a strong lineup overall, Hicks' speed and benefit of hitting in that lineup do not provide enough to make him a compelling fantasy option, except perhaps in deep five-outfielder leagues.

The Cincinnati Reds re-signed right-hander Derek Law to a minor-league deal on Monday that includes an invitation to major-league spring training. Law spent the 2022 season with both the Reds and Detroit Tigers, combining for a 4.12 ERA (4.89 FIP), 1.58 WHIP, 17 strikeouts and eight walks in only 19 2/3 relief innings over 17 appearances. The 32-year-old will have an opportunity to make the team's Opening Day roster, but fantasy managers can ignore him if he does. Law has six years of major-league experience and a career 4.21 ERA (4.13 FIP), 1.45 WHIP and 21.9 percent strikeout rate in 193 appearances (four starts) covering 201 innings pitched.

Free-agent left-hander Ryan Sherriff announced on his Twitter account over the weekend that he signed a minor-league deal with the Boston Red Sox. Sherriff spent all of 2022 in the minor leagues for the Philadelphia Phillies and had a nice 2.51 ERA, 1.39 WHIP, 18 strikeouts and seven walks in just 14 1/3 relief innings over three different levels. The 32-year-old southpaw reliever has spent four seasons in the majors and has a career 3.65 ERA (3.98 FIP), 1.31 WHIP, two saves and 18.7 percent strikeout rate in 44 relief outings covering 44 1/3 innings. If Sherriff is on Boston's major-league roster at any point in 2023, he won't be worth considering in fantasy leagues.

The Pittsburgh Pirates designated infielder Miguel Andujar for assignment on Friday to make room on the 40-man roster for the recently signed Andrew McCutchen. The former New York Yankee, Andujar appeared in only 36 games in 2022 (27 with the Yankees) and slashed .235/.257/.311 with a .568 OPS, one home runs, 17 RBI, 13 runs scored and four stolen bases in 140 plate appearances. The 27-year-old hit .297 with an .855 OPS, 27 home runs and 92 RBI in his first full big-league season in 2018 with the Yankees, but he's struggled to come anywhere near that mark since. If Andujar goes unclaimed on waivers, there's a good chance he could return to Pittsburgh's organization and serve as infield depth in 2023.

Free-agent right-hander Aaron Slegers officially announced on his Twitter account on Thursday that he is retiring from professional baseball. A right shoulder injury that limited him to two rehab outings last season is the big reason why he's decided to hang up his cleats after just five years in the big leagues. In his final MLB season in 2021 with the Los Angeles Angels, Slegers had a career-high 6.97 ERA (5.62 FIP), 1.87 WHIP, 15 walks and a career-high 25 strikeouts in 31 relief innings. The 30-year-old reliever will finish his short MLB career with a 3-4 record, 5.46 ERA (5.01 FIP), 1.36 WHIP, three saves, 28 walks and 59 strikeouts in 89 innings covering 49 appearances (six starts) with the Angels, Minnesota Twins and Tampa Bay Rays.

The Chicago Cubs designated left-hander Anthony Kay for assignment on Friday to make room on the 40-man roster for the recently signed Trey Mancini. The Cubs claimed Kay off waivers from the Toronto Blue Jays in December, but he could be moving to another organization shortly. The 27-year-old southpaw tossed only two relief innings for the Blue Jays in 2022 due to injuries and allowed one earned run while striking out three. In his four seasons in the big leagues with Toronto, he's posted a 5.48 ERA (4.67 FIP), 1.63 WHIP, 38 walks and 77 strikeouts in 70 2/3 innings pitched over 28 outings (seven starts). If he clears waivers this time around, Kay could remain in Chicago's organization.

The Seattle Mariners designated left-hander Justus Sheffield for assignment on Thursday to make room on the 40-man roster for infielder Tommy La Stella, who was signed to a one-year deal Thursday. Sheffield has pitched in five major-league seasons (four with Seattle) and has gone 12-12 with a 5.47 ERA (4.77 FIP), 1.63 WHIP and 18.2 percent strikeout rate in 186 innings covering 48 appearances (33 starts). Last year in Seattle he had a 3.86 ERA (4.83 FIP), 1.29 WHIP, six walks and seven strikeouts in just 11 2/3 innings over six outings (one start). If Sheffield isn't claimed off waivers or traded to another team, he could return to the organization as both starting and relief depth.

The San Francisco Giants signed free-agent first baseman Ronald Guzman to a minor-league deal on Thursday. Guzman spent the first four years of his major-league career with the Texas Rangers, slashing .227/.304/.414 with a .718 OPS, 31 home runs, 104 RBI, 91 runs scored and three stolen bases in 243 games played. He ended up playing in only three games with the New York Yankees in 2022, going hitless in six at-bats with five strikeouts. The 28-year-old will provide the Giants with some depth at the first base position after veteran slugger Brandon Belt left in free agency this offseason.
