Walker (6-3) allowed five runs (three earned) on six hits and five walks over 6.1 innings during Tuesday's game against the Cardinals. He did not record a single strikeout nor did he factor into the decision.

Walker continues to struggle with his control, as the 24-year-old has now walked nine batters over his past two starts. To add insult to injury, Walker went without a strikeout for the first time since a blowup outing on Aug. 6 of last season. Though his ERA still sits at a respectable 3.50, his recent form hasn't exactly left his fantasy owners feeling overly confident with the young hurler. Walker is set for another tough test as he's scheduled to face the Rockies in his upcoming start Sunday.
