Wesneski (forearm) threw a 25-pitch bullpen session Tuesday, Maddie Lee of the Chicago Sun-Times reports.

Wesneski has been rehabbing his strained right forearm at the Cubs' facility in Arizona, and Tuesday's workout marked his first mound activity since being placed on the injured list July 20. The 26-year-old appears to be multiple weeks out from being reinstated from the IL.

The Nationals designated Weems for assignment Tuesday, Jessica Camerato of MLB.com reports.

The transaction frees up space on the 40-man roster. Weems has struggled mightily this season, collecting a 6.70 ERA and 35:24 K:BB across 41.2 relief innings.

The Guardians optioned Strzelecki to Triple-A Columbus on Tuesday.

He's clearing out to make room for Tuesday's starter, Matthew Boyd. Strzelecki has permitted three runs with a 9:3 K:BB over 11.2 relief innings for the Guardians this season.

The Twins designated Blewett for assignment Tuesday.

The transaction clears a spot on the 26-man and 40-man rosters for the addition of Zebby Matthews, who has been called up to make his major-league debut Tuesday. Blewett retired the only three batters he faced during his brief time with the Twins.

The Red Sox re-signed Keller to a minor-league contract Tuesday, Chris Hatfield of SoxProspects.com reports.

Keller refused an option to Triple-A Worcester from the Red Sox but has quickly re-upped on a minor-league deal. He will likely move into Worcester's rotation.

The Angels claimed Burke off waivers from the Rangers on Tuesday.

Burke had been designated for assignment earlier this week and has now been scooped up by an American League West rival. The left-handed reliever holds a career 4.22 ERA and 172:53 K:BB across 182.1 innings over parts of four big-league seasons.

The Angels claimed Robertson off waivers Tuesday from St. Louis.

Robertson has been at the Triple-A level since returning from the injured list in late June. He had logged a 7.48 ERA across 21.2 innings for Triple-A Memphis prior to being DFA'd by the Cardinals. The 25-year-old reliever is expected to report to Triple-A Salt Lake.

The Athletics designated Muller for assignment Tuesday.

The left-hander last pitched since Aug. 3 versus the Dodgers and surrendered six runs across one inning. Muller had a 3.02 ERA, 1.13 WHIP and 32:9 K:BB in 41.2 frames this season prior to that outing, but he won't retain his place on Oakland's 26-man and 40-man rosters.

The Phillies optioned Marte to Triple-A Lehigh Valley on Tuesday.

The right-hander was recalled by Philadelphia on July 20 and will return to the minors after he surrendered seven runs across two-thirds of an inning Saturday at Arizona. Even prior to that ugly showing, Marte had a 4.63 ERA, 1.67 WHIP and 21:13 K:BB across 23.1 big-league innings this season.

Kopech earned a hold against the Brewers on Monday, walking one batter and striking out two in a scoreless inning.

Kopech handled the eighth frame and worked around a two-out walk to keep Milwaukee off the scoreboard. He earned his fourth hold in six appearances since joining the Dodgers on July 29. Kopech has yet to allow a run over 6.1 innings with his new team, and he's surrendered just one hit while posting a 10:1 K:BB. The righty reliever has quickly become Los Angeles' top setup man, but it's unclear if he'll get any save opportunities after working as the White Sox's closer for most of the season prior to being dealt.
