| May 16 2024 | Waldichuk underwent Tommy John surgery on his left elbow Wednesday, Martin Gallegos of MLB.com reports. | ROTOWIRE RECOMMENDS: Waldichuk was initially diagnosed with a UCL tear last October. He opted for a minor procedure on his elbow last fall in hopes of avoiding the surgery he eventually had Wednesday. The left-hander figures to be sidelined until around midseason of 2025. |

| May 13 2024 | Waldichuk will undergo left elbow surgery Wednesday, Martin Gallegos of MLB.com reports. | ROTOWIRE RECOMMENDS: 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. |

| May 8 2024 | Waldichuk (elbow) will visit with Dr. Neal ElAttrache on Monday, Martin Gallegos of MLB.com reports. | ROTOWIRE RECOMMENDS: Waldichuk recently had a setback while throwing a live batting practice session. He was diagnosed last October with a UCL sprain and flexor strain but chose a more conservative Tenex procedure to remove scar tissue and help alleviate pain. More will be known after Monday's exam, but his upcoming meeting with Dr. ElAttrache would seem to suggest that Waldichuk's treatment plan hasn't panned out as anticipated. |

| May 7 2024 | Waldichuk (elbow) experienced a setback after throwing a 25-pitch live batting practice April 29 and is shut down for the time being, MLB.com reports. | ROTOWIRE RECOMMENDS: The left-hander has not thrown since that session and is slated to be reevaluated in coming days. It's naturally a tough break for Waldichuk, who opened the season on the 60-day IL but had been making uninterrupted progress prior to this recent stumble. Given Waldichuk will almost certainly require a full-length rehab assignment whenever he is cleared for game action, he may be hard-pressed to be ready for activation before mid-June. |

| Apr 29 2024 | Waldichuk (elbow) threw 25 pitches against live hitters Monday, Martin Gallegos of MLB.com reports. | ROTOWIRE RECOMMENDS: Waldichuk continues to advance in his rehab, and he's now scheduled to throw a sim game before potentially being sent out on a rehab assignment, per Gallegos. The southpaw figures to get a day or two off before his scheduled sim game. |

| Apr 24 2024 | Waldichuk (elbow) threw a successful 30-pitch bullpen session Tuesday, MLB.com reports. "Waldichuk looked really good and got his velocity up from his last bullpen," said A's manager Mark Kotsay. "He's trending in the right direction." | ROTOWIRE RECOMMENDS: Waldichuk has now thrown three bullpen sessions over the last eight days alone, certainly an encouraging sign with respect to his surgically repaired elbow's strength. The left-hander is slated to throw additional bullpen sessions during the Athletics' road trip before facing hitters in a simulated game at some point next week, after which he'll head out on a rehab assignment, per Kotsay. |

| Apr 22 2024 | Waldichuk (elbow) could begin a rehab assignment sometime next week, Martin Gallegos of MLB.com reports. | ROTOWIRE RECOMMENDS: The lefty has joined the Athletics on their road trip and will throw four bullpen sessions before being sent out on a rehab assignment. Waldichuk was diagnosed last October with a UCL sprain and flexor strain, but he chose a more conservative Tenex procedure to remove scar tissue and help alleviate pain. He will be built up as a starter, so Waldichuk would figure to need most, if not all, of his 30-day rehab allotment before being considered for the A's rotation. The southpaw is on the 60-day injured list, so he won't be eligible for activation until late May. |
