MLB Player News

The Athletics acquired Klein, Jared Dickey and Mason Barnett from the Royals on Tuesday in exchange for Lucas Erceg, Mark Feinsand of MLB.com reports.

Klein has allowed four runs in 5.2 frames during his brief time in the majors this season. He's put up a 30.7 percent strikeout rate but also a 16.1 percent walk rate in the minors. Klein had been on the Royals' major-league roster, but it's not clear whether he'll report to Oakland or Triple-A Las Vegas.

Slaten (elbow) remains limited to playing catch from 75 feet out as of Monday, Gabrielle Starr of the Boston Herald reports.

Slaten landed on the 15-day injured list July 12 with right elbow inflammation and was believed to be in line for a minimum-length stay on the shelf, but a bout with an illness ended up delaying him from starting up a throwing program. He looks like he'll still need some time to increase his throwing distance off flat ground before the Red Sox clear him for mound work.

The Mariners acquired Chargois from the Marlins on Tuesday in exchange for right-hander Will Schomberg, Christina De Nicola of MLB.com reports.

Chargois missed the first two-plus months of the season due to a neck issue, but he's pitched well in middle relief since being activated in mid-June with a 1.62 ERA, 1.32 WHIP and 12:7 K:BB over 16.2 innings. The right-hander will bolster Seattle's bullpen depth and is also under team control for 2025.

The Mariners optioned Speier to Triple-A Tacoma on Tuesday.

Speier has regressed this season, most notably in the control department -- he's issued 12 walks in 19.2 innings. He's being sent out in favor of a fresh bullpen arm.

The Tigers traded Chafin to the Rangers on Tuesday in exchange for Joseph Montalvo and Chase Lee, Jeff Passan of ESPN.com reports.

Chafin has been one of the Tigers' top bullpen arms this season, logging a 3.16 ERA in 37.0 innings with eight holds and 50 strikeouts. The southpaw will join a righty-heavy bullpen in Texas and could be used as a setup man for closer Kirby Yates.

The Royals acquired Erceg from the Athletics on Tuesday in exchange for Mason Barnett, Will Klein and Jared Dickey, Jeff Passan of ESPN.com reports.

Erceg hasn't even reached arbitration eligibility yet, but the Athletics have decided to take advantage of the prices being paid in the relief market. The 29-year-old former position player has posted a 3.68 ERA and 41:13 K:BB across 36.2 innings out of Oakland's bullpen in 2024, collecting three saves along the way. Erceg could get a shot to close in Kansas City, especially due to James McArthur's recent struggles.

The Astros acquired Ferguson from the Yankees on Tuesday in exchange for right-hander Kelly Austin, Jack Curry of YES Network reports.

Ferguson will provide the Astros with additional bullpen depth after appearing in 42 games with the Yankees this season. The 27-year-old logged a 5.13 ERA, a 1.50 WHIP and 10 holds across 33.1 innings for New York. He's not expected to see much high-leverage work in Houston.

The Angels acquired Baumann from the Giants on Tuesday in exchange for cash, Robert Murray of FanSided.com reports.

San Francisco designated Baumann for assignment Saturday, but he'll regain a 40-man roster spot with a new organization. He's out of minor-league options and thus will need to be added to the Angels' 26-man active roster. The right-hander reliever holds a 4.84 ERA and 1.44 WHIP over 35.1 innings across 36 appearances with the Giants, Mariners and Orioles.

The Red Sox designated Walter (shoulder) for assignment Tuesday, Gabrielle Starr of the Boston Herald reports.

The move frees up a spot on the 40-man roster for trade-deadline acquisition Lucas Sims. Walter has been sidelined all season with a shoulder strain, an injury he suffered in early March. Assuming he clears waivers, Walter will remain on Triple-A Worcester's 60-day injured list.

The Red Sox acquired Sims from the Reds on Tuesday in exchange for right-hander Ovis Portes, Robert Murray of FanSided.com reports.

Sims has posted a 3.57 ERA and 40:20 K:BB over 35.1 innings in 2024 as a member of the Reds bullpen. The pending free agent boasts a career 27.5 percent strikeout rate but also an 11.9 percent walk rate. He'll slot in as a setup man for Boston in front of closer Kenley Jansen.
