José Fermín hit his fifth homer Monday off the Cubs’ David Peterson.

Fermín typically comes off as a significantly less talented version of Luis Arraez, but every once in a while, the 27-year-old makes it worth wondering if there’s something more in store. Tonight’s homer was one of those moments, as it came with an 81.3-mph bat speed that he just doesn’t seem like he should be capable of. Fermín has been adequate in hitting .253/.317/.385 in his part-time role this year, but he might be a lot more interesting if he just started swinging hard all of the time.
