MLB Player News

The Diamondbacks acquired Nootbaar from the Cardinals on Monday in exchange for right-hander Daniel Eagen, left-hander Sandro Santana and a player to be named later.

An eighth-round draft pick by St. Louis in 2018, Nootbaar will move on after nine years as a member of the organization. After getting off to a delayed to the 2026 season while recovering from offseason surgery on his heels, the 28-year-old outfielder returned from the injured list June 5 and slashed .234/.333/.354 with three home runs, one stolen base, 22 runs and 16 RBI in 183 plate appearances. Nootbaar should settle into a regular role in the corner outfield for an Arizona squad that currently has three other outfielders in Lourdes Gurriel (adductor), Jordan Lawlar (hamstring) and Tommy Troy (shoulder) on the injured list.

The Guardians traded Hartle, Will Dion, Kendeglys Virguez and Nick Mitchell to the Nationals on Monday in exchange for Foster Griffin, Mark Feinsand of MLB.com reports.

A 23-year-old southpaw, Hartle has a 3.86 ERA, 1.38 WHIP and 88 strikeouts in 93.1 innings at Double-A. He projects as either a back-end starter or middle reliever.

Marsh is out of the lineup for Monday's game against the Nationals.

The left-handed-hitting Marsh had been seeing fairly steady opportunities against left-handed pitching earlier this season, but he's moved into more of a strong-side platoon role since the All-Star break. With southpaw Andrew Alvarez on the bump for Washington, Edmundo Sosa will get the nod in left field over Marsh, who is slashing .231/.270/.370 (72 wRC+) over 115 plate appearances versus lefties.

Realmuto is out of the lineup for Monday's game against the Nationals.

Garrett Stubbs will receive a turn behind the plate while Realmuto rests for the first of four games against Washington. Realmuto had caught in each of the Phillies' previous four contests, going 2-for-12 with a solo home run, three walks and four runs.

The Brewers acquired Senzatela from the Rockies on Monday in exchange for Mark Manfredi and Juan Martinez.

Senzatela found a groove as a reliever this season, posting a 3.61 ERA and 46:17 K:BB over 52.1 innings. The veteran right-hander has a 7.45 ERA since the beginning of June, but a 20:8 K:BB over 19.1 innings suggests he had some bad luck. Senzatela will likely help set up in Milwaukee and is set to reach free agency after the season.

Manfredi and Juan Martinez were traded from the Brewers to the Rockies on Monday in exchange for Antonio Senzatela, Mark Feinsand of MLB.com reports.

Manfredi is a 26-year-old lefty reliever who has split the year between Double-A and Triple-A. He boasts a 3.35 ERA, 1.23 WHIP and 68:22 K:BB in 45.2 innings across 34 appearances, but his 11.4 percent walk rate is a tad high, as he is also not much of a groundball pitcher (40.9 GB%).

The Giants acquired Mayer (forearm) from the Red Sox on Monday in exchange for left-hander Erik Miller and outfielder Carlos Gutierrez.

The Red Sox are selling low on Mayer, who has slashed just .223/.278/.346 in his first 364 plate appearances at the major-league level. He's just 23 years old and was considered an elite prospect not long ago, making Mayer a nice get for the Giants. On the shelf since June 26 due to a stress reaction in his left forearm, Mayer has resumed taking part in fielding drills and hitting off a tee and facing soft-toss pitching, but he remains without a timetable to return to game action. He could take over as San Francisco's everyday second baseman once he's back to full health.

Kent and Henry Lalane were traded from the Yankees to the Giants on Monday in exchange for Heliot Ramos, Mark Feinsand of MLB.com reports.

Lalane is the headliner in the return for San Francisco. Kent, who has been sidelined with an undisclosed injury since July 5, has a .302/.359/.433 slash line with six home runs, 20 steals, a 16.1 percent strikeout rate and a 107 wRC+ in 76 games as a 22-year-old at High-A. He has played 41 games at shortstop, 25 games at second base and eight games at third base this year.

Atlanta acquired Uberstine from Boston on Monday in exchange for outfielder Eli White, Mark Feinsand of MLB.com reports.

The 27-year-old made his MLB debut in a 2.2-inning relief appearance with the Red Sox on April 5 but has otherwise spent the entire season in the minors. Over 32 innings at Triple-A Worcester, the right-hander posted a 2.81 ERA, 1.00 WHIP and 37:11 K:BB. He'll likely join the bullpen at Triple-A Gwinnett as he moves on to a new organization.

Atlanta acquired Davitt from the White Sox on Monday in exchange for catcher Joey Bart, Mark Feinsand of MLB.com reports.

After making his second appearance of the season with the White Sox over the weekend, Davitt was designated for assignment earlier Monday when the team needed to open up a spot on the 40-man roster. The 26-year-old righty will reclaim a 40-man spot in Atlanta and is likely to begin his time in the organization at Triple-A Gwinnett. Davitt has spent most of the 2026 campaign with Chicago's Triple-A affiliate in Charlotte, turning in a 6.22 ERA, 1.49 WHIP and 64:25 K:BB across 59.1 innings.
