Waldichuk will undergo left elbow surgery Wednesday, Martin Gallegos of MLB.com reports.

Waldichuk elected to have a more conservative procedure after being diagnosed with a UCL sprain and flexor strain last October, but he recently had a setback and will require another operation. The Athletics won't provide more details until Waldichuk's surgery is completed Wednesday, but the upcoming procedure promises to be more invasive and will likely prevent him from pitching this season.

Flexen and the White Sox won't play Monday against the Nationals after the game was postponed due to inclement weather in Chicago, LaMond Pope of the Chicago Tribune reports.

The game will be made up as part of a doubleheader Tuesday, with Flexen taking the mound for the first game. The 29-year-old right-hander has a 2-3 record over six starts this season with a 4.29 ERA and 1.21 WHIP across 35.2 innings.

Eovaldi (groin) could be ready to throw off a mound this weekend, Jeff Wilson of RangersToday.com reports.

Eovaldi did some more flat-ground throwing Monday and might be ready to take the next step forward by getting back on a mound to toss a bullpen session. While he looks to be trending in the right direction, Eovaldi doesn't look as though he'll be ready to return from the 15-day injured list when first eligible Saturday. He's coming back from a strained right groin.

Carter will undergo an MRI on his back Monday, Jeff Wilson of RangersToday.com reports.

Carter is out of the lineup for a fourth straight game Monday against the Guardians, with the last three absences due to a lower-back problem. The fact that the injury has necessitated an MRI points to a possible stint on the 10-day injured list, but more information on Carter's should be known once the results are in. Ezequiel Duran will start in left field for the Rangers on Monday.

Gelof (oblique) rejoined the Athletics on Monday and could be activated from the 10-day injured list during their four-game series in Houston, Martin Gallegos of MLB.com reports.

Gelof played consecutive full rehab games with Triple-A Las Vegas on Saturday and Sunday, which was the last box he needed to check before returning to the big club. The Athletics seem content to give Gelof a rest day Monday before likely activating him ahead of Tuesday's contests. Gelof has been out since late April with a strained left oblique.

The Guardians recalled Strzelecki from Triple-A Columbus on Monday, Mandy Bell of MLB.com reports.

Strzelecki will give the Guardians another relief option while Sam Hentges is on paternity leave. He has made three scoreless appearances out of the bullpen for the big club this season.

The Guardians placed Hentges on the paternity list Monday, Mandy Bell of MLB.com reports.

Hentges will likely miss the entire three-game set against the Rangers before rejoining the club this weekend for its series versus the Twins. Peter Strzelecki was recalled from Triple-A Columbus and will assume Hentges' spot in Cleveland's bullpen.

Francis (forearm) will begin a rehab assignment with Triple-A Buffalo on Tuesday, Shi Davidi of Sportsnet.ca reports.

Francis is slated for two innings and/or 40-to-45 pitches in the outing. While Francis looks like he'll be stretched back out as a starter on his rehab assignment, he appears more likely to fill a long-relief role once he returns from the 15-day injured list.

Rodriguez (back) threw a bullpen session Monday, Shi Davidi of Sportsnet.ca reports.

He's slated for another bullpen session in the coming days and might be ready for a rehab assignment after that as he recovers from thoracic spine inflammation. Rodriguez had been starting for the Blue Jays before going on the 15-day injured list, but it's uncertain if he'll reclaim his rotation spot from Alek Manoah by the time he's activated.

White Sox manager Pedro Grifol said Monday that Leone (back) will begin throwing live batting practice sessions soon, James Fegan of SoxMachine.com reports.

Leone isn't expected to require a rehab assignment before being activated from the 15-day injured list, which should come early next week when he's first eligible.
