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.

Detroit Tigers catcher Carson Kelly (rib cage) has been scratched from Friday's starting lineup against the visiting Kansas City Royals with left rib-cage soreness. He will be available off the bench, however. In his place, Jake Rogers will start behind the plate and will bat eighth against Royals right-hander Seth Lugo. The fact that Kelly is available off the bench means that his injury probably isn't very serious, so the 29-year-old backstop could have a chance to return for Saturday's contest. The former second-round pick of the St. Louis Cardinals in 2012 is hitting just .205 (9-for-44) on the year with a homer and six RBI for Detroit. Rogers has been even worse, going 6-for-45 (.133) with a homer and two RBI, so DFS gamers should look elsewhere at the catcher position on Friday.

San Diego Padres right-hander Yu Darvish (neck) threw a side session on Wednesday, after which "reports were favorable," according to manager Mike Shildt. "He was on the gas, but didn't have it to the floor... it was a positive first step." Darvish was put on the 15-day injured list on April 17 (retroactive to April 15) and last pitched on April 14 against the Los Angeles Dodgers. The 37-year-old was shut down in September of last year with a stress reaction in his right elbow and has dealt with back and neck issues in the past. It sounds like Darvish is improving, but at 37 years old, his recurring neck issue is something to keep an eye on when he returns. Before hitting the IL, he had a 4.18 ERA and 1.27 WHIP with 22 strikeouts and 10 walks in 23 2/3 frames over his first five starts.

Kansas City Royals outfielder Hunter Renfroe finds himself on the bench again on Friday against the Detroit Tigers. This will be the second straight game that Renfroe will be starting on the bench. In his absence, the left-handed-hitting Adam Frazier will make the start in right field for the Royals and will hit eighth against Tigers right-hander Reese Olson. The 32-year-old Renfroe has hit just .149 (10-for-67) with two home runs, 10 RBI, five walks and 16 strikeouts in his first 72 plate appearances in 2024 and is quickly losing playing time in Kansas City's outfield rotation. Frazier, also 32, hasn't been much better, going 11-for-55 (.200) with no homers, four RBI and one stolen base in 22 games. He's never faced Olson in his career.

Miami Marlins left-hander Jesus Luzardo (elbow) was scratched from his scheduled start on Friday versus the Washington Nationals and will undergo testing for left-elbow discomfort, according to the team. The Marlins can ill-afford another injury to one of their starting pitchers, but the good news is they should be getting left-hander Braxton Garrett (shoulder) back soon. For now, fantasy managers that have the 26-year-old Luzardo rostered must keep him stashed and hope for the best. It's more bad news for a pitcher that has gotten off to a tough start in 2024, as he's posted a 6.58 ERA and 1.42 WHIP with 27 strikeouts and 13 walks in five starts covering 26 innings. In Luzardo's place, pitching prospect Anthony Maldonado will make the spot start against the Nats.

Atlanta Braves second baseman Ozzie Albies (toe) was activated from the 10-day injured list on Friday after he needed only the 10 days to recover from a fractured right big toe. Albies will be back in Atlanta's starting lineup on Friday for the series finale against the visiting Cleveland Guardians and left-hander Logan Allen, and fantasy managers will want to get him back into all starting lineup this weekend. The 27-year-old switch-hitter was hitting a strong .317/.386/.492 with two home runs and two stolen bases in 15 games played before injuring his toe and remains one of the better fantasy second baseman in a potent Braves lineup. Luis Guillorme and David Fletcher were splitting time at the keystone with Albies out. Fletcher was sent to the minors on Thursday.

Washington Nationals starting pitcher MacKenzie Gore had an impressive performance against the Los Angeles Dodgers in Thursday's tough luck loss. The lefty tossed six quality innings and allowed seven hits, one run, two walks and recorded four strikeouts. Gore's only run allowed was a home run from outfielder Teoscar Hernandez in the top of the second inning. Gore has really taken a step forward in 2024 and is now 2-2 with a 3.12 ERA to go along with 31 strikeouts and eight walks in 26 innings. Despite the walks, Gore is looking like the pitcher many projected him to be when he was the top pitching prospect in the league as a prospect. Gore will look to keep it going in another tough matchup versus the Texas Rangers on Tuesday.

San Diego Padres outfielder Jurickson Profar went 2-for-4 with a home run and a walk in Thursday's loss against the Colorado Rockies. Porfar took Nick Mears deep in the top of the seventh inning for his third homer of the season. The veteran has quietly been having a nice season for the Padres with a .295 batting average and 18 RBI. Profar should eventually regress, but he is worth riding while his bat is hot. For now, Profar is worth rostering, but managers would be wise to test the trade market and try to sell-high on the veteran. Profar will look to stay warm versus the division rival San Francisco Giants and Kyle Harrison on Friday evening.

Seattle Mariners starting pitcher Luis Castillo put together a strong performance versus the Texas Rangers to pick up his second victory of the season on Thursday. Castillo tossed six innings and allowed four hits, two runs, two walks and struck out six on the evening. Castillo has steadily improved as the season has gone on and managers could put to rest any worries from his early season outings. The 31-year-old remains one of the top pitchers in the game and managers can expect to have an ace in most of his starts moving forward. Next up is a matchup versus the Atlanta Braves on Tuesday. Even against a good lineup, Castillo is pretty much a must-start.

Seattle Mariners first baseman Ty France went 1-for-4 with a two-run homer in Thursday's victory against the division rival Texas Rangers. The round tripper would be the first of the season for France, who is coming off a disappointing 2023 season. France has been hitting the ball well with a .266 batting average, but he has not done much to help fantasy managers with just six RBI. He has been hitting the ball very hard this year, so more power can come along, but for now he remains a better player for the Mariners than fantasy. He is worth keeping an eye on to see if contact will turn into power, but is more of a watch-list candidate in most formats at this time.

New York Yankees starting pitcher Nestor Cortes picked up the loss on Thursday versus the Oakland Athletics. The lefty tossed seven frames of three-run ball and allowed five hits with no walks and four strikeouts. The lefty earned a quality start, but didn't get much out of the Yankees offense to help him. Cortes had a rough 2023 campaign with a 4.97 ERA, but he has bounced back in 2024 thus far with a 3.50 ERA in his first six starts of the season. Cortes is worth rostering in most formats, but will face a tough Baltimore Orioles lineup in his next outing and might be best served on the bench in daily leagues for that contest.

New York Yankees catcher Jose Trevino made some noise with his bat during Thursday's game against the Oakland Athletics. He went 2-for-4 with a solo home run in the loss to the A's. The solo blast by Trevino was the only run the Yankees could put on the board during Thursday's loss. Trevino has been decent, slashing .273/.347/.756 with two homers and eight RBI across 44 plate appearances.

Texas Rangers infielder Josh Smith continued his strong campaign versus the Seattle Mariners on Thursday. Smith went 2-for-4 with a double and a home run in the loss to the Mariners. He has seemingly come out of nowhere and been a reliable option for this offense. He's slashing 292/.393/.417 over 72 at-bats, but he's more of a bench option which limits his fantasy value.

Kansas City Royals catcher Salvador Perez came up clutch for his team during Thursday's game against the Toronto Blue Jays. The veteran catcher blasted a two-run home run off right-hander Jose Berries. That home run ended up being enough as the Royals won the game 2-0. The 33-year-old now has seven home runs on the year and is showing no signs of slowing down.

Minnesota Twins relief pitcher Griffin Jax shut the door on the Chicago White Sox on Thursday, helping secure a 6-3 victory. Jax came in with the bases loaded and one out with a four-run lead and managed to escape with only one runner crossing home (on an error), picking up his fourth save in the process. Jax has filled in admirably as the impromptu closer after Jhoan Duran went down before the season started, posting a 2.53 ERA and 0.94 WHIP while striking out 15 batters in 10 IP. He is also 4-for-5 in save chances. Unfortunately for Jax and his fantasy managers, Duran could be back at any point as he is currently on a rehab assignment. Once he is back, Jax will likely shift back to a set-up role.

Chicago Cubs relief pitcher Hector Neris notched his third save on Thursday, slamming the door on the Houston Astros in a 3-1 win. Neris was a little shaky in his inning of work, walking a pair before getting out of it. Since manager Craig Counsell said that Adbert Alzolay was being taken out of the closer role last weekend, Neris has converted on all three of his save opportunities and apparently taken that role over. He should be added in most leagues where saves are important.

Seattle Mariners relief pitcher Andres Munoz picked up his third save of the season on Thursday, locking down the Texas Rangers in a 4-3 win. Munoz tossed up goose eggs across the board in his inning of work as he didn't allow a baserunner and didn't strike anyone out either. It was the 25-year-old's first save since April 6, as he has been used in non-save situations and has also blown a save since then. It seems like Munoz is still Seattle's highest-leverage pitcher and should see the most save chances, but his season total might be held back by being used in the seventh or eighth innings on occasion.

Colorado Rockies relief pitcher Justin Lawrence threw a perfect ninth inning in a 10-9 victory over the San Diego Padres, picking up his second save in the process. Lawrence struck out one and didn't allow a baserunner in his inning of work. Although he hasn't been good this year, as evidenced by his 5.59 ERA and 1.55 WHIP, Lawrence still might be the best Colorado has in its bullpen. He has the team's last two saves and is likely to remain in that role. He doesn't need to be owned in standard leagues, but deeper league managers who play in saves-only formats might want to give Lawrence a look.

Los Angeles Dodgers closer Evan Phillips locked down the Washington Nationals on Thursday, helping secure a 2-1 win. Phillips looked great in this one, striking out a pair in a perfect ninth inning. For the season, the 29-year-old has been excellent, posting a 0.84 ERA and 1.13 WHIP with 13 strikeouts in 10 IP. Phillips should continue getting the bulk of the Dodgers save chances, making him an elite closing option in fantasy.

Texas Rangers first baseman Nathaniel Lowe clubbed his first home run of the season on Thursday despite taking a 4-3 loss at the hands of the rival Seattle Mariners. The 28-year-old appeared in only his fifth game of the season due to an oblique injury suffered late in spring training but he's been off to a hot start in a small sample. Lowe is hitting .294 (5-for-17) with a homer, a double, three walks, three runs scored, and .929 OPS across his first 20 trips to the plate. Armed with pop and plenty of patience at the plate, Lowe hit .262 with 17 home runs, 89 runs, 82 RBI, a 12.8% BB%, and a .774 OPS while appearing in 161 games in the 2023 season, the third straight season in which he has appeared in at least 157 contests.
