Arizona Diamondbacks manager Torey Lovullo said that right-hander Zac Gallen's (hamstring) bullpen session went well on Monday and he will start on Wednesday in his normal spot in the rotation against the visiting Los Angeles Dodgers. Gallen was forced from his start last Friday with hamstring spasms, but the 28-year-old was never too worried that he would miss his next start, and he wasn't wrong. In traditional single-year leagues, fantasy managers will probably want to leave him in their starting lineups this week despite the tough matchup against the division-rival Dodgers. But in DFS at a high cost, you probably want to fade Gallen against one of the best offenses in the league. Through his first 32 innings in 2024, Gallen has a 3.38 ERA and 1.22 WHIP with nine walks and 35 K's.

San Diego Padres right-hander Yu Darvish (neck) is being activated from the 15-day injured list and will start on Tuesday at Petco Park against the visiting Cincinnati Reds, according to manager Mike Shildt. Darvish has been on the injured list since April 17 due to neck tightness and didn't require a minor-league rehab assignment, so fantasy managers in all fantasy formats should be pretty hesitant to throw the 37-year-old veteran right back into the fold for Tuesday's action. Darvish wasn't throwing the ball particularly well before his injury, either, as he was sporting a 4.18 ERA and 1.27 WHIP with 22 strikeouts and 10 walks in 23 2/3 innings over his five starts. The Reds rank 22nd in the league in OPS, but their lineup is dangerous and can explode at any time.

Detroit Tigers manager A.J. Hinch confirmed that right-hander Matt Manning will start Game 2 of the team's doubleheader on Tuesday against the St. Louis Cardinals. Manning has fared well in his two spot start with the Tigers this year, allowing five hits (two home runs) and four earned runs while walking six and striking out 10 in 12 1/3 innings against the New York Mets and Minnesota Twins. The 26-year-old is likely to be sent back to Triple-A Toledo after serving as the team's 27th man on Tuesday, but given the matchup against a St. Louis team that could be resting some key starters in Game 2, Manning is worth a look as a streaming option in fantasy in this matchup. Through almost the first month of the 2024 season, the Cardinals hold the fourth-lowest team OPS in the big leagues at .636. Only the A's, Marlins and White Sox have been worse.

Los Angeles Dodgers catcher Will Smith added some run support in Monday's 8-4 win against the Arizona Diamondbacks. Smith went 1-for-4, with his only hit being a solo home run while walking once. The 29-year-old is having a solid season, slashing .363/.404/.539 through 26 games. He is 37-for-102 with nine doubles, three homers, 16 runs, 22 RBI, nine walks, and 16 strikeouts. Smith remains one of the top catchers across all fantasy leagues and is a priority to start for fantasy managers.

Seattle Mariners starting pitcher Bryce Miller had himself a day on Monday in a 2-1 win against the Atlanta Braves. Miller went seven innings while striking out 10 batters, walking one, and allowing one earned run. He is 3-2 on the season, pitching 35 innings with a 2.04 ERA while allowing 19 hits, nine runs, five homers, 12 walks, and 39 strikeouts in six starts. The 25-year-old has a 9.93 K/9 and a 3.06 BB/9, backing his success this year on the mound. His next projected start is against Houston, and the way he is pitching, fantasy managers should have him starting no matter who the opponent is.
