The Guardians optioned McCaughan to Triple-A Columbus on Monday.

McCaughan was knocked around for two runs on four hits and two walks over two relief innings in Sunday's 6-5 win over the Blue Jays in his lone appearance with the Guardians following his call-up from Triple-A last Wednesday. He's being sent back to the minors in favor of a fresh bullpen arm.

Atlanta voided Kerr's option to Triple-A Gwinnett and placed him on the 15-day injured list with a left elbow UCL injury.

Kerr had been sent down to Triple-A on June 15, but he never made an appearance for Gwinnett following the demotion, so the transaction has been rescinded. Atlanta hasn't provided much detail regarding Kerr's injury, but UCL damage is often a precursor to Tommy John surgery.

The Cardinals activated Robertson (elbow) from the 15-day injured list and optioned him to Triple-A Memphis on Monday.

Robertson has moved past the right elbow injury that sent him to the IL a month ago, but he'll remain at Memphis, where he had been on a rehab assignment. The right-hander holds a 4.38 ERA and 14:2 K:BB over 12.1 innings during his time in the majors this season.

The Red Sox recalled Winckowski from Triple-A Worcester on Monday, Mac Cerullo of the Boston Herald reports.

Winckowski will give the Red Sox a fresh arm in the bullpen who's capable of covering multiple innings. Boston was in need of some reinforcement in the bullpen after the team leaned on eight relievers to cover all nine innings of Sunday's 7-4 win over the Reds.

The Red Sox recalled Campbell from Triple-A Worcester on Monday, Chris Henrique of Beyond the Monster reports.

Campbell held a 12.79 ERA in seven appearances earlier this season with the Red Sox before getting injured and then optioned. He righted the ship while at Worcester, posting a 2.19 ERA and 18:3 K:BB in 12.1 frames.

The Red Sox optioned Keller to Triple-A Worcester on Monday, Chris Henrique of Beyond the Monster reports.

Keller has allowed 10 runs over 16.2 innings as a low-leverage reliever for the Red Sox. He's being replaced by a fresh arm after he threw 31 pitches and allowed three runs over one inning in Sunday's 7-4 win over the Reds.

Howard is expected to serve as the Giants' primary pitcher out of the bullpen in Monday's game against the Cubs, Alex Pavlovic of NBC Sports Bay Area reports.

Left-hander Erik Miller will serve as the Giants' opening pitcher but isn't likely to work more than an inning or two before turning the game over to Howard, who is expected to eat up the bulk of the innings. Howard covered just one frame in his last appearance, but prior to that, he averaged nearly four innings and more than 60 pitches in his first four outings for the Giants following his May 28 call-up from Triple-A Sacramento.

Miller will serve as the Giants' opening pitcher for Monday's game against the Cubs, Alex Pavlovic of NBC Sports Bay Area reports.

Miller has taken to the opener role quite well, allowing two runs (one earned) with an 8:4 K:BB over 6.2 innings covering his first six opener assignments. Spencer Howard is in line to follow Miller as the Giants' primary pitcher.

Garrett gave up a hit and struck out one in a scoreless eighth inning Sunday to record his seventh hold of the season in a win over the Cubs.

Edwin Diaz came on the ninth but got ejected for a foreign substance, and Jake Diekman wound up getting a one-out save as Mets manager Carlos Mendoza scrambled to fill in for his closer. Diaz is facing a 10-game suspension, and based on Mendoza's bullpen usage while the right-hander was out injured, Garrett should be viewed as the favorite to handle any save chances during that time. Diekman, Adam Ottavino, Drew Smith and even potentially Dedniel Nunez could all be factors in the ninth as well, however.

Puk (1-8) was credited with the win Sunday over the Mariners, striking out two batters in two perfect innings of relief.

The left-hander took over from Kyle Tyler to begin the fifth inning with the Marlins ahead 6-2, and Puk needed only 20 pitches (14 strikes) to rack up six outs and become the pitcher of record. He appears to be regaining his prior form now that he's no longer in the rotation -- through 10.2 innings in June, Puk sports a 3.38 ERA, 0.94 WHIP and 10:1 K:BB. Should closer Tanner Scott be dealt by the trade deadline, Puk would be a candidate for saves given his experience in the role last year.
