St. Louis Cardinals shortstop/outfielder Jose Barrero had a solid game at the plate in Monday's 6-3 win over the Pirates. The 27-year-old went 2-for-4 with a double, a solo home run, three RBI, and two strikeouts. Barrero turned on a third-inning Carmen Mlodzinski fastball, landing it into the left-field bullpen for his first homer of the season and first as a Cardinal. Barrero only has 14 plate appearances with the Cardinals but took advantage of the opportunity with Masyn Winn (ankle) out of the lineup with a left ankle sprain. Despite the strong game, he is slashing just .231/.286/.538 with a 35.7% strikeout rate and had not played in the big leagues since 2023.

New York Yankees relief pitcher Devin Williams continued his dismal start to the season in Monday's 4-3 loss to the Padres. Williams came in to pitch the top of the eighth inning with a 3-0 lead. He got the first out on a strikeout, allowed a walk and a single, and got the second out on a strikeout. He then allowed another walk before being relieved by Luke Weaver, who allowed two more runs to score, one of which was charged to Williams. The 30-year-old, who has been an excellent reliever throughout his career, has already been removed as the team's closer and owns a 10.03 ERA, a 1.97 WHIP, and a 10.03 K/9 rate in 11 2/3 innings of work. While Williams could theoretically earn his way back into save opportunities, he will need to drastically turn things around to make that a potential chance. Ideally, fantasy managers could hold onto Williams on their bench to wait for that chance if they can afford the roster spot.

Chicago Cubs outfielder Ian Happ had a big game in a 9-2 win over the San Francisco Giants on Monday. Happ went 1-for-3 with a homer and three RBI to help power the Cubs to the win. The veteran outfielder opened up the scoring when he launched a two-run homer in the bottom of the third inning and later came back to add a sacrifice fly in the sixth. Happ is now hitting .287 with three homers, 29 runs, 19 RBI, and one steal across 150 at-bats this season. The homers will come as Happ has four 20-homer seasons on his resume.

Arizona Diamondbacks outfielder Corbin Carroll turned in an excellent game in a 5-4 loss to the New York Mets on Monday. Carroll went 2-for-4 with a homer, a walk, two runs, and an RBI, but it wasn't quite enough in the close loss to New York. The star outfielder kicked off the scoring in the game with a solo homer in the bottom of the first inning. Carroll is now hitting .287 with 10 homers, 28 runs, 27 RBI, and five stolen bases across 150 at-bats this season. While he isn't stealing bases at the rate he did in the 2023 and 2024 seasons when he combined to swipe 89 bags, Carroll remains one of the top fantasy outfielders in all leagues.

Kansas City Royals shortstop Bobby Witt Jr. went 2-for-3 with a double, a walk, a run, an RBI, and two steals in a 3-0 win over the Chicago White Sox on Monday. Witt, who just saw a 22-game hitting streak end on Friday, is now hitting .314 with 14 doubles, four homers, 22 runs, 18 RBI, and 11 steals across 137 at-bats this season. The star infielder remains one of the elite fantasy producers in all of baseball.
