While any elbow-related issue is always cause for some concern, there’s no reason to think there is any structural problem here. As manager Brad Ausmus noted, it is sometimes necessary to treat this issue with surgery — see, e.g., here — but that’s not currently an option. Regardless, there is no reason to think the nerve issue could balloon into a larger issue.
For the time being, Fulmer will simply take a week off while receiving treatment for inflammation. The idea, he says, is “to give me time to let the nerve calm down a little bit.” Fulmer added that he has experienced these symptoms — “numbing and tingling in the last two fingers” — for some time, but never previously during a game.
Fulmer, 24, will hope to bounce right back onto the mound after a brief layoff, though surely the club will be watching closely and won’t take any chances. After all, he is one of the best young starters in baseball. Fulmer has thrown 299 1/3 innings of 3.31 ERA ball since the start of the 2016 season, and won’t qualify for arbitration until after the 2018 season — when he’s lined up to be a Super Two.
