As expected, the New York Mets activated outfielder Starling Marte from the bereavement list on Tuesday and optioned infielder Mark Vientos to Triple-A Syracuse in a corresponding move. However, Marte won't make the start on Tuesday versus the visiting Chicago Cubs, with DJ Stewart in right field and batting seventh against Cubs right-hander Javier Assad. The 35-year-old Marte will miss his fourth straight game but should be back in the lineup on Wednesday for the Mets. He's managed to stay healthy so far this year and is hitting a strong .288 (30-for-104) with four home runs, 12 RBI, six stolen bases and 16 runs scored in his first 25 games. Stewart has never faced Assad in his career and is hitting just .200 so far with three home runs for the Mets.

Kansas City Royals catcher Salvador Perez (back) is playing first base and is batting cleanup for the Royals on Tuesday against right-hander Jose Berrios and the Toronto Blue Jays. Freddy Fermin is doing the catching and will bat sixth. Perez was scratched from Monday's lineup with back tightness, but he singled in a pinch-hit appearance late in the game and is back in the lineup a day later. Fantasy managers will want to get the 33-year-old All-Star back into their starting lineups immediately. Perez has been going off offensively with a .346/.404/.596 slash line with seven home runs in his first 29 games this year. He has a lot of experience against Berrios in his career, too, but he's hit just .214 with a home run and five RBI in 42 at-bats.

Toronto Blue Jays outfielder Daulton Varsho is not in the starting lineup on Tuesday with the team facing a left-handed pitcher. With Varsho getting the day off, Cavan Biggio will make the start in right field for the Jays and will hit ninth in the batting order against Royals left-hander Cole Ragans. Varsho has gone 5-for-17 (.294) with a solo home run against southpaws so far in 2024, but he also has just one hit in his last 14 at-bats over his last four games to drop his season slash line to .233/.324/.500. The 27-year-old left-handed slugger has added six home runs, 14 RBI and three stolen bases. Varsho should be back in Toronto's starting lineup on Wednesday. Biggio has very little fantasy upside in the nine-hole. He's hitting .229 (16-for-70) on the year with a homer and six RBI.

Houston Astros general manager Dana Brown said that the team and struggling first baseman Jose Abreu have decided that he will be optioned to the Florida Complex League in West Palm Beach, Florida, effective on Wednesday "to get some at-bats and his timing back right." The 37-year-old right-handed slugger also got off to a slow start with the Astros last year, but his struggles this year have fallen to another level. He's currently slashing an embarrassing .099/.156/.113 with no home runs, three RBI, three walks and 18 strikeouts in 77 plate appearances over 22 games. Abreu was a virtual lock for 100 RBI each season during his time with the Chicago White Sox from 2014-22, but he's fallen on hard time in Houston and isn't a must-stash in mixed fantasy leagues. Jon Singleton will see more playing time at first base now that Abreu is headed to the farm.

Miami Marlins left-hander Braxton Garrett (shoulder) will make another minor-league rehab start this week before possibly joining the big-league club. Garrett resumed his rehab assignment on April 26 with Triple-A Jacksonville and threw three-plus innings in a 59-pitch outing. He was on track for a return before experiencing "dead arm" during his April 15 bullpen session, which was unrelated to his previous left-shoulder impingement, according to manager Skip Schumaker. The 26-year-old southpaw has yet to debut in the big leagues in 2024 but should be picked up off the waiver wire and stashed in deeper mixed fantasy leagues if he's available after he broke out for the Fish in 2023. Given all of the injuries to Miami's starters this year, Garrett will undoubtedly be inserted into the rotation immediately when he comes off the injured list.
