4. Dustin May
Dustin May is one of the filthiest pitchers in the entire league and was well on his way to potentially being a first-time All-Star in 2021. May debuted in 2019 and put together a solid shortened 2020 season in which he finished with a 2.57 ERA in 56 innings pitched.
Fast forward to the 2021 season where May cracked the starting rotation and had a promising start to the season. However, he ultimately tore his UCL on a May 1 start against the Milwaukee Brewers, resulting in the hard-throwing right-hander needing Tommy John surgery. He missed the rest of 2021 and returned late in 2022.
May still had his filthy stuff in 2022 but was obviously still not 100% acquainted with being back on the mound at the MLB level. With a full offseason to rest and recover, May is slated to be a prominent member of the starting rotation in 2023 and could pitch his way to the All-Star Game.
A big factor in whether or not May will be able to earn an All-Star nod is how careful the Dodgers are managing his workload. Los Angeles has been cautious with young pitchers in the past and May might not rack up the innings required to be an All-Star.
If he does, though, then he has a good chance to garner votes because of how good his stuff is. May's ceiling for the 2023 season is as high as becoming the No. 2 pitcher in this rotation. But if he needs more time to recover, he could end up out of the rotation altogether.
