Colorado Rockies injury news: Tyler Anderson to undergo knee surgery

According to multiple reports, including this one from Thomas Harding of MLB.com, Colorado Rockies starting pitcher Tyler Anderson will be going under knee surgery.

Colorado Rockies starting pitcher Tyler Anderson has had numerous knee issues this season, dating all the way back to spring training. He had a stint on the injured list due to knee inflammation and this latest one will keep him on the injured list for, at least, most of the rest of the season, if not the entire season.

Anderson, 29, has had five starts this season and he struggled in all five starts as he pitched to a 11.76 ERA, going 0-3. He averaged just over 4 innings per start, giving up 14.4 hits per nine innings, allowing 3.5 home runs per nine innings, and walking nearly five batters per nine innings as well.

After those five starts, he was optioned back to Triple-A Albuquerque. However, due to his knee issues, he hasn’t made an appearance. It remains to be seen whether or not he will be placed on the major league injured list or the minor league injured list.

That is of note because it could impact Anderson’s MLB service time and potential arbitration as he could be eligible for arbitration for a second time this offseason.

It is a big blow to the Rockies rotation and the depth in their rotation, a rotation that has had its fair share of struggles this season. By ERA, the Rockies starting rotation is 24th in baseball with a 5.00 ERA. That number is the worst among the 15 National League teams. Anderson and Rockies ace Kyle Freeland have struggled the most as Freeland has pitched to a 6.02 ERA in 10 starts.

It seems to look there is a chance that Anderson could return towards the end of the season but especially if he cannot return to the rotation this season, the Rockies trade outlook on starters could drastically change, particularly if they are buyers.
