ST. LOUIS — Miles Mikolas’ second pitch of the game was a fastball down the middle, which Washington Nationals leadoff hitter CJ Abrams pummeled for a double. Quickly, Mikolas snapped into focus. “I can’t be doing this again,” he muttered to himself.

But to compete for such a spot, the Cardinals need to part ways with both Mikolas and Fedde. Of the two, Fedde is the most likely to be moved, as he could be traded at the deadline for prospects or as part of a deal for a new starter.
