The Mets traded Gervase to Tampa Bay on Tuesday in exchange for Tyler Zuber, Will Sammon of The Athletic reports

Gervase has spent the 2024 season with the Mets' Double-A affiliate, generating a 3.25 ERA across 27.2 innings with 46 strikeouts. A 12th-round draft pick in 2022, the Rays will look to further develop the 24-year-old.

The Tigers acquired Lee and Joseph Montalvo from the Rangers on Tuesday in exchange for Andrew Chafin, Evan Grant of The Dallas Morning News reports.

Lee has missed much of 2024 due to injury but has looked like a potential late-inning relief arm when healthy. He holds a 4.19 ERA and 139:46 K:BB over 105.1 innings during his time at the Triple-A level.

The Tigers acquired Montalvo and Chase Lee from the Rangers on Tuesday in exchange for Andrew Chafin, Evan Grant of The Dallas Morning News reports.

Montalvo has collected a 2.44 ERA and 73:19 K:BB over 59 innings this season with High-A Hickory. The 22-year-old is a nice get as part of a package for a rental reliever.

The Twins acquired Richards on Tuesday in exchange for infielder Jay Harry, Ken Rosenthal of The Athletic reports.

Richards will provide the Twins with a right-handed option out of the bullpen who's capable of covering multiple innings. The 31-year-old covered 52.1 frames over his 45 appearances with the Blue Jays this season, logging a 4.64 ERA with seven holds and a 49:24 K:BB.

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.
