Profile: I wish I could find the Tweet. It was a Joe Kelly GIF with a comment praising his "stuff" - except the GIF depicted him brutally missing three straight spots by a combined several feet. A so-called "live arm," his average fastball velocity has generally trailed only Yordano Ventura and Nathan Eovaldi among starting(-ish) pitchers. For years, Kelly's results failed to match the stuff, given his heavy reliance on a suboptimal sinker. He replaced it with a traditional four-seamer - a pitch with twice the whiffs but also twice the home run problem. His primary off-speed pitch, his slider, remains an even more volatile feast-or-famine offering as well, inducing the most whiffs in his repertoire but also the highest isolated power (ISO). These issues and his poor control keep him perpetually at arm's length from proper success. You'd think a permanent move to the bullpen beckons him; indeed, his K%-BB% almost quadrupled upon transitioning last season. (Dave Dombrowski alluded to the idea of using him as a swingman, for better or for worse.) Such a move would make Kelly potentially more valuable to the Red Sox but decidedly less valuable to your fantasy team. He's not worth consideration in all but the deepest formats. (Alex Chamberlain)

The Quick Opinion: Whether he serves as a swingman or full-time reliever, Kelly likely won't serve much purpose for fantasy teams, regardless of his role or level of success. Unless you're a sad Red Sox fan, he's not worth your consideration.
