Mayer went 2-for-2 with a home run, a double, two runs scored and two RBI in Friday's 5-2 win over the Padres.

Mayer doubled and scored in the third inning before adding a two-run homer in the sixth. The long ball was particularly impressive, coming in his first at-bat against a lefty this season after he went just 4-for-26 against southpaws in 2025. The 23-year-old is off to an encouraging start, going 5-for-17 with four extra-base hits and five runs scored through seven games. Entering last season as one of the game's top prospects, he still offers upside as a potential post-hype sleeper in 2026.

The Astros recalled Whitcomb from Triple-A Sugar Land on Friday.

The 27-year-old will join the Astros ahead of Friday's series opener against the A's with Isaac Paredes being placed on the bereavement list. Given Houston's glut of infielders, Whitcomb is likely to fill a reserve role while up with the big club.

The Brewers announced Friday that Pratt signed an eight-year contract extension with club options for 2034 and 2035, and the team subsequently selected his contract to the major-league roster and optioned him to Triple-A Nashville, Jack Stern of BrewerFanatic.com reports.

The $50 million extension was reported early in the week, but it apparently took a few days for the two sides to hammer out all the details. Regardless, the 21-year-old Pratt has now been officially added to the 40-man roster and could be with Milwaukee for the next decade. He's received his first taste of the Triple-A level this year after posting a .242/.344/.354 slash line with eight homers and 30 steals at Double-A in 2025. Pratt will likely need to show some improvement with his bat before the Brewers give him a look in the majors, but his glove at shortstop is likely already big-league ready.

Cardinals manager Oliver Marmol said that Winn departed Friday's game against the Tigers due to left hip tightness, Jeff Jones of the Belleville News-Democrat reports.

Winn was noticeably gimpy when running out a groundball in the fifth inning and was then lifted for a pinch hitter in the seventh. He noted that he first felt tightness as a result of overdoing it in the batting cage Tuesday. Winn is expected to sit out Saturday but could be back in action Sunday for St. Louis.

Lee is not in Friday's starting lineup against the Rays because of an illness, Matthew Leach of MLB.com reports.

He is available off the bench despite missing yesterday's game due to the illness as well. Tristan Gray gets the start at shortstop in his place. Lee is off to a slow start, hitting .154 (2-for-13) with zero homers and just one RBI, and he's at some risk for losing his starting shortstop job this season after an underwhelming 2025 (.655 OPS).

Schmitt went 3-for-3 with an RBI and a walk in Thursday's 7-2 win over the Mets.

Schmitt singled in the second inning, drew a walk in the third, hit an RBI single in the fifth and added another base hit in the seventh as the Giants earned a comfortable win. The 27-year-old infielder continues to start at first base in place of Rafael Devers, who has yet to play defense due to lingering hamstring tightness. Schmitt went hitless in San Francisco's opening series against the Yankees but recorded his second multi-hit performance of the season Thursday. He's slashing .273/.360/.318 with two RBI, a double and a stolen base across 25 plate appearances in seven games.

Griffin is starting at shortstop and batting seventh in his major-league debut Friday against the Orioles.

Pittsburgh officially added the 19-year-old to the big-league roster earlier Friday, and he'll slot into the bottom third of the order in his first game with the major-league club. Griffin has just five games under his belt at the Triple-A level but has a .950 OPS overall during his minor-league career. The top prospect is also expected to finalize a nine-year, $140 million contract extension in the near future.

Gray will start at shortstop and bat ninth in Friday's game against the Rays.

It's the second consecutive start at shortstop for Gray, who is 3-for-9 with a 1:4 BB:K in the early going this season. Brooks Lee should still handle the lion's share of starts at shortstop for Minnesota over the long haul.

Lee is not in the lineup for Friday's game versus the Rays.

Lee started four of the first five games of the season but has now been on the bench for two in a row. The Twins will roll with Tristan Gray as their starting shortstop in Friday's home opener.

Mateo slugged a two-run home run in his only at-bat during Thursday's 17-2 rout of the Diamondbacks.

The utility infielder pinch hit for DH Dominic Smith in the ninth inning and took position player James McCann deep. Mateo has been used sparingly early in the year, appearing in just three of Atlanta's first seven games and getting only four plate appearances, and it'll likely take an injury or two to put him in a fantasy-friendly role.
