Ryan Feltner of Colorado Rockies Placed on 15-Day Injured List Due to Back Spasms, Expected Return in Late May

Ryan Feltner's absence impacts the Colorado Rockies' pitching rotation. He started six games this season with a 4.75 ERA and 25 strikeouts in 30 1/3 innings. The team relies on other starters like Kyle Freeland and Antonio Senzatela to fill the gap until Feltner returns.

Feltner's injury also means more pressure on the Rockies' bullpen. Relief pitchers like Tyler Kinley and Jimmy Herget might have more innings to cover. The Rockies will need strong performances from both the starters and relievers to handle upcoming games without Feltner.
