Mena has been diagnosed with a teres major strain in his right shoulder and is expected to be out for multiple weeks, Jack Sommers of SI.com reports.

Mena felt discomfort in his right shoulder while warming up in the bullpen before his outing against the Reds on Friday, when he yielded one run on two hits and one walk while striking out one batter in one inning. Mena was placed on the 15-day injured list Saturday, and a clearer timeline for his return will be known once he's been given the green light to start a throwing program.

Holman will be the Athletics' opening pitcher for Monday's game against the Angels, Martin Gallegos of MLB.com reports.

It's the second time this month that Holman has served in an opener capacity. He's expected to be followed by Jeffrey Springs in bulk relief.

The Angels activated McDaniels (biceps) from the 15-day injured list and designated him for assignment Monday.

McDaniels is over the biceps injury that sent him to the IL in early May, but the Angels have decided not to add him back to their active roster. The Rule 5 pick will be available for other teams to claim via waivers, but if he clears he must be offered back to the Dodgers for $50,000.

The Angels selected Anderson's contract from Triple-A Salt Lake on Monday.

Anderson made five relief appearances for the Halos earlier this season, allowing seven runs with a 10:3 K:BB over 10 innings. He's been pitching as a starter at Salt Lake and will provide length out of the Angels' bullpen.

The Angels optioned Fermin to Triple-A Salt Lake on Monday.

Fermin has collected a 4.82 ERA and 15:5 K:BB over 9.1 innings with the Angels this season. He's being replaced by Shaun Anderson, who offers more length in the bullpen.

The White Sox are expected to call up Taylor from Double-A Birmingham prior to Tuesday's game in Houston, James Fegan of SoxMachine.com reports.

Taylor has been dominant since being moved to the bullpen at Birmingham, tossing 9.1 scoreless innings with an 18:1 K:BB over his last nine appearances. It's not clear whether the White Sox have given up on trying to develop him as a starting pitcher, but Taylor will be broken into the big leagues as a reliever. The 23-year-old has an electric arm and could push for high-leverage appearances sooner rather than later.

The Diamondbacks placed Graveman on the 15-day injured list Monday, retroactive to June 8, due to a right hip impingement.

Graveman's hip injury may have played a part in his disastrous outing in the second game of Saturday's doubleheader against the Reds, when he allowed six runs on five hits and one walks in one inning. It's the second time he'll be on the IL, with a back injury preventing him from making his season debut until May 13. Christian Montes De Oca was recalled from Triple-A in a corresponding move.

The Diamondbacks recalled Montes De Oca from Triple-A Reno on Monday.

Montes De Oca served as the Diamondbacks' 27th for Saturday's twin bill against the Reds. He was optioned to Triple-A on Sunday, but he's back with the big club after Kendall Graveman (hip) was placed on the 15-day injured list. Montes De Oca made his major-league debut in the second game of Saturday's doubleheader, allowing no hits and one walk while striking out two across 2.2 scoreless innings.

Stephan (elbow) will begin a rehab assignment with the rookie-level Arizona Complex League Guardians on Tuesday, Tim Stebbins of MLB.com reports.

Stephan missed the entirety of last season following a UCL reconstruction, but he's finally been cleared for game action following a long rehab process. His rehab assignment will be a lengthy one given how much time Stephan has missed, but he should be ready to rejoin the Guardians' bullpen before the All-Star break.

Walter underwent surgery Monday to repair his right lat, Tim Stebbins of MLB.com reports.

The Guardians didn't divulge a timetable for Walters, but the operation will undoubtedly end the reliever's season. Walter had been shelved since late May with the injury and last week was transferred to the 60-day injured list.
