Last Sept. 5, Tyler Matzek pitched the only complete-game shutout of the Rockies' 2014 season. Commanding the mound, the 24-year-old rookie beat the San Diego Padres 3-0 at Coors Field, allowing three hits, walking one and striking out six. He threw just 103 pitches, 75 for strikes.
It was one of the finest pitching performances in Rockies history.
Last Wednesday, pitching for the short-season Single-A Boise (Idaho) Hawks in Eugene, Ore., Matzek lasted one-third of an inning. He didn't allow a hit, but he walked five batters and hit another.
In 3 minor-league innings this season, Matzek has walked 15 batters and posted a demoralizing 35.
