New York Yankees designated hitter J.D. Martinez (back) is hitting fifth in his debut with the team on Friday against the visiting St. Louis Cardinals and right-hander Miles Mikolas. Martinez is getting a late start to the 2024 campaign after signing with the team late in March. The 36-year-old veteran then tweaked his back while playing in extended spring training, further delaying his debut. Martinez is back now, though, and will give first baseman Pete Alonso more protection in the lineup. Martinez hit a strong .271/.321/.572 with 33 home runs with the Los Angeles Dodgers in 2023, and while he can still provide some decent pop in mixed fantasy leagues, nobody should be expecting him to be quite that good in New York. The Mets plan to ease Martinez back in, so don't be surprised to see him get frequent days of rest.

St. Louis Cardinals right-hander Miles Mikolas will look to get straightened out when he takes the ball for a road contest against the New York Mets. The 35-year-old was knocked around for nine hits, including three homers, leading to five earned runs allowed in just 4 1/3 innings in a losing effort against the Brewers his last time out. It was the second consecutive outing and third of five on the season in which the veteran has allowed five earned runs in less than five innings this season. The rough outing raised his ERA to 6.49 through five starts, although his 4.05 xFIP, 4.28 SIERA, and solid 6% BB% suggest positive regression is likely moving forward.

New York Mets designated hitter J.D. Martinez (back) is set to make his debut with the team on Friday against the visiting St. Louis Cardinals. He's expected to give All-Star first baseman Pete Alonso more protection in the batting order after hitting 33 home runs in just 479 plate appearances in 2023 with the Los Angeles Dodgers. However, Martinez won't be hitting behind Alonso every day, at least not to start. Manager Carlos Mendoza said the team will ease Martinez into regular playing time, which makes sense given his age (36) and the fact he dealt with a back injury while ramping up this spring. Fantasy managers can't expect another 30-plus homer season from Martinez while getting a late start to the year, but he can provide notable pop in mixed leagues if he can stay healthy.

Colorado Rockies outfielder Charlie Blackmon is not in the starting lineup for Thursday's afternoon contest against the visiting San Diego Padres. It's not surprising to see the club give the veteran a spell in an afternoon game following an evening game on Wednesday in which Blackmon led off as the designated hitter and went 0-for-4 with a strikeout in his club's 5-2 loss. The 37-year-old is off to a sluggish start this season, hitting .228 with one homer, one stolen base, and a .659 OPS across 86 trips to the plate. At this point, Blackmon's power and speed just aren't there and he should be left on the waiver wire in all fantasy formats, including NL-only leagues.

As long as New York Mets designated hitter J.D. Martinez (back) comes out of his final minor-league rehab game with Triple-A Syracuse on Wednesday without a setback, the team expects him to be their starting DH on Friday night against the visiting St. Louis Cardinals. Martinez signed with the Mets late in spring training but didn't join the big-league club for Opening Day because he needed to get his timing down first. A back issue has delayed his arrival to the big leagues in New York, but it sounds like his 2024 debut is right around the corner on Friday. Injuries are probably going to continue to be an issue, but if Martinez is available in your fantasy league, he's worth a pickup if you're in need of a power boost. The 36-year-old six-time All-Star hit .271/.321/.572 with an .893 OPS, 33 home runs and 103 RBI in 113 games with the Dodgers in 2023.

The Kansas City Royals placed right-hander Jordan Lyles (personal) on the inactive list on Saturday, and the team is not disclosing the reason for his absence other than describing it as a "personal matter." There's no timeline for his return, but because of the type of inactive list Lyles was placed on, it opened a 40-man roster spot for the Royals to call up veteran right-handed reliever Tyler Duffey. Lyles has thrown five scoreless innings with three strikeouts in five appearances out of KC's bullpen during the 2024 regular season, but he hasn't pitched since April 12. With no defined role and most of his work coming in mop-up duty this year, however, the 33-year-old journeyman belongs on fantasy waiver wires while he's unavailable. There's no clear-cut fantasy beneficiary of his absence, either.

New York Mets designated hitter J.D. Martinez (back) will move his rehab to Triple-A Syracuse this week, and "it's possible" the team could activate him when they get home on Friday for the start of a three-game series with the St. Louis Cardinals, per manager Carlos Mendoza. After receiving a cortisone shot due to lower back tightness, Martinez returned to a minor-league rehab assignment on Sunday and is on track to make his 2024 regular-season debut in Queens in Week 4 of fantasy baseball. With the Mets struggling to find consistency in the heart of their batting order, the 36-year-old All-Star slugger figures to slot right in as the No. 5 hitter in the lineup immediately upon his move to New York's active roster. After slashing .271/.321/.572 with 33 home runs, 27 doubles, and 103 RBI across 432 at-bats (113 games) with the Los Angeles Dodgers last year, Martinez should be rostered for those in need of power numbers.

Toronto Blue Jays designated hitter Justin Turner hit his second home run of the season in Friday's 5-1 win over the Padres. It was a solo shot, and he also added an RBI single. The veteran has six multi-hit games on the year and is now batting a robust .345 on the young season, with two home runs, 11 RBI, and eight runs scored.

It's "very unlikely" that designated hitter J.D. Martinez (back) will join the New York Mets on their upcoming West Coast road trip, according to manager Carlos Mendoza. The Mets begin their road trip this Friday, April 19, against the Los Angeles Dodgers and will wrap it up in San Francisco against the Giants on Wednesday, April 24. Martinez didn't sign with New York until late in spring training, so he stuck around in extended spring training to get his timing down at the plate before injuring his back in early April. The 36-year-old could start a rehab assignment later this week and make his 2024 debut with the Mets later this month or in early May. When he's finally ready to return, Martinez can still provide some thump from the DH spot and will give the Mets more protection for All-Star first baseman Pete Alonso.

New York Mets designated hitter J.D. Martinez (back) is scheduled to resume swinging the bat on Monday and is still a few days away, according to manager Carlos Mendoza, of getting back into a minor-league game. Martinez hasn't played since last Saturday for Low-A St. Lucie after which he started to feel back tightness. The veteran right-handed slugger received a shot in his back last Tuesday. The Mets signed the 36-year-old late in spring training, but he didn't join the club for Opening Day as he tried to get his timing down at the plate before hurting his back. He probably won't resume his minor-league rehab assignment until later this week, but if he continues to feel good this weekend, there's a possibility that Martinez could join the Mets for his team debut sometime next week.

Colorado Rockies outfielder Charlie Blackmon (illness) is out of the starting lineup ahead of Friday's game against the Toronto Blue Jays. Rockies' manager Bud Black said Blackmon is feeling under the weather, so they will hold him out of this contest. The expectation is that this will be a one-game absence for the veteran outfielder. In the meantime, Kris Bryant will function as the designated hitter, while Elehuris Montero covers first base versus right-hander Kevin Gausman on Friday.

New York Mets outfielder J.D. Martinez (back) will be shut down for three to five days after receiving a cortisone shot. The veteran slugger is dealing with lower back tightness, so hopefully this shot and rest will help him. Martinez wasn't expected to join the Mets this week, but this news means his season debut will be pushed back further. The Mets should give an update on his timetable in a few days.

The New York Mets have designated pitcher Julio Teheran for assignment on Tuesday, the team announced. Teheran signed a one-year $2.5 million deal with the Mets on April 5 after he failed to make the Baltimore Orioles roster. The right-hander made one start for New York allowing four runs on six hits across 2 and 2/3 innings. Following the outing, the Mets designated the right-hander for assignment, and in his spot, New York called up right-handed pitcher Dedniel Nez.

If the Seattle Mariners decide to skip young right-hander Emerson Hancock's next turn in the starting rotation and if righty Bryan Woo (elbow) isn't ready to return from the injured list by then, newly signed left-hander Dallas Keuchel could be an option to temporarily replace Hancock. The 12-year-old veteran and former Cy Young winner threw five scoreless innings in his season debut with Triple-A Tacoma on Sunday. Levi Stoudt, Casey Lawrence and Jhonathan Diaz could also be candidates for a spot start for the M's. It would be a cool comeback for Keuchel, 36, but his upside would be limited for fantasy managers and his stay in Seattle's rotation would likely be a short one with either Hancock or Woo replacing him sooner or later.

New York Mets designated hitter J.D. Martinez (body) will not join the team for their upcoming series against the Atlanta Braves, according to manager Carlos Mendoza. The veteran slugger is reportedly dealing with general body soreness and will get the next few days off. Martinez was signed late in the offseason and seems to be getting back into game shape, but the process is taking longer than expected. While there are some injury concerns, the 36-year-old should be able to provide solid power for fantasy teams whenever he makes his debut.

New York Mets right-hander Julio Teheran will officially make his 2024 debut with the Mets on Monday in Atlanta against the division-rival Braves, and he'll be good for 70 to 75 pitches. Teheran will also potentially be available out of the bullpen on Friday in the series opener against the visiting Arizona Diamondbacks. The 33-year-old veteran was trying to win a roster spot with the Baltimore Orioles in spring training this year but was cut before Opening Day and has landed in the National League with the Mets. He'll give the team some rotation help with both Kodai Senga and Tylor Megill on the injured list due to shoulder injuries. At best, Teheran is a waiver-wire pickup for the pitching-needy in deep NL-only leagues, and he should be avoided in his first start versus Atlanta.

New York Mets designated hitter J.D. Martinez will head to a minor-league affiliate, and there's a possibility that he joins the team in Atlanta for the start of a series against the division-rival Braves early next week. Martinez wasn't included on the team's Opening Day roster after signing with the club late in spring training. The 36-year-old veteran slugger stayed behind in extended spring training to get his swing right, but it appears he's getting close to making his debut with the team. To start the year, D.J. Stewart has been serving as the Mets' primary designated hitter, but Martinez will eventually take over those duties to give first baseman Pete Alonso more protection in the lineup. If you're looking to add a little more thump to your fantasy team and Martinez is available, pick him up and stash him now.

The New York Mets signed free-agent right-hander Julio Teheran to a major-league deal on Wednesday, and club officials believe that he'll be capable of starting Monday's series opener against the division-rival Atlanta Braves. With Kodai Senga (shoulder) and Tylor Megill (shoulder) both on the injured list with shoulder injuries, the Mets are desperate for rotation help in the early going. The 33-year-old Teheran was competing for a roster spot with the Baltimore Orioles, so apparently he's stretched out enough to come right in and make a start for the Mets early next week. He had a 4.40 ERA and 1.13 WHIP in 71 2/3 innings for the Milwaukee Brewers last year but should be avoided in all fantasy formats for what is expected to be his first start of 2024 against the Braves.

The Atlanta Braves signed relief pitcher Jackson Stephens and catcher Sandy Leon to minor-league deals Tuesday, per The Athletic's David O'Brien. Stephens elected free agency in March after being outrighted to Triple-A Gwinnett by the Braves and served as a decent reliever for the Braves from 2022 through 2023. Leon should serve as catcher depth for the organization with Sean Murphy (oblique) on the injured list with an oblique injury but will not contribute much offensively. Neither of these players should factor into the fantasy landscape at this time.

Former American League Cy Young winner Dallas Keuchel is signing a minor-league deal with the Seattle Mariners on Tuesday. The plan will be for the veteran left-hander to report to Triple-A Tacoma. The 36-year-old southpaw won the Cy Young award all the way back in 2015 with the Houston Astros and hasn't made an All-Star team since 2017. Last year in 10 appearances (six starts) for the Minnesota Twins, Keuchel went 2-1 with a 5.97 ERA (4.56 FIP) and 1.67 WHIP with 18 walks and 25 strikeouts in 37 2/3 innings pitched. There's no guarantee that he'll make it back to the big leagues in Seattle, so fantasy managers in all leagues can probably leave Keuchel to the waiver wire. In his 12 big-league seasons, Keuchel has fanned just 6.9 hitters per nine innings, too, so there will be very little upside if he's making starts for the M's in 2024.
