Nick Rumbelow

Rumbelow's season was a brief one. After being sent to Triple-A toward the end of spring training, he required Tommy John surgery after just one outing. While the lost year is obviously not ideal, the righty is still just 25 years old, so if he's able to come back from the surgery, he'll still have plenty of time to establish himself within the organization. Rumbelow made his big league debut in 2015, striking out 15 in 15.2 innings with a mid-90s fastball, so when healthy he will likely get another look in the major league bullpen somewhere down the line. Given the typical Tommy John surgery timetable, Rumbelow may be out until around the All-Star break, and given all of the missed time the club will likely send him back to the minors, at least at first, to get back in the swing of things.
