A pair of former MLB hurlers have decided to give up their comeback efforts and move on from the game …

In a Twitter post, southpaw Charlie Furbush says that he underwent numerous procedures and rehabilitation efforts over the past few seasons but just couldn’t get back to full health. Soon to turn 33, Furbush has missed virtually all of the past three seasons after his career was knocked off track by rotator cuff surgery. Before that, though, he turned in several quality relief seasons for the Mariners after initially breaking into the bigs with the Tigers. Furbush wraps up his career with a 3.97 ERA and 9.3 K/9 against 3.1 BB/9 over 260 2/3 total frames at the game’s highest level.

Another former fourth-round draft pick, righty Jon Moscot, is calling it quits at just 27 years of age. He explains in an Instagram post that he’s now halting what had been a lengthy effort to recover from mid-2016 Tommy John surgery. Understandably, Moscot says it was an emotionally difficult decision to make. After all, he cracked the majors at 23 years of age and surely thought he’d receive plenty of opportunities in the future. Moscot ultimately took the ball just eight times at the game’s highest level. Prior to a rough ’16 campaign that ended with the aforementioned procedure, Moscot had thrown 221 innings of 3.34 ERA ball at Triple-A.
