Rockies' Boone Logan done for season after undergoing elbow surgery

Colorado Rockies' left-hander Boone Logan will miss the remainder of the season after undergoing surgery to remove a bone spur from his throwing elbow yesterday, the club has announced. The 30-year-old has been disastrous this season for the Rockies, and last played on August 24th.

This marks the second consecutive year in which Logan has undergone an elbow surgery of some sort, as he had bone chips removed last offseason. Despite the surgery, Colorado still handed him a hefty three-year, $16.5 million deal that was thought to be ludicrous at the time, and seems even worse in retrospect.

Logan was outright terrible for the Rockies this season. In 35 appearances, he posted a 6.84 ERA, 5.12 FIP, and -0.3 fWAR. However, some numbers point to a possible return to form. Boone allowed a .379 BABIP this season, which was over 50 points above his career average. His strikeout (27.6%) and walk (9.5%) rates are both steps up for him, and his 2.85 xFIP is a positive sign. Still, Logan is owed nearly $12 million over the next couple seasons, and will need to rebound in order to justify that salary.

Boone is just the latest in a series of Rockies' players to be shut down for the season. The list includes lineup anchors Troy Tulowitzki and Carlos Gonzalez, as well as key rotation pieces in Tyler Chatwood, Brett Anderson, and Jhoulys Chacin.
