The move really reflects just how poorly the Cardinals bullpen has pitched in recent days. Cleto, I believe, had the Cardinals’ longest active scoreless innings streak at 1.1 innings.
Valdes, however, hopefully will solidify the Cardinals’ issues against left handed batters. While he struggled in the starting rotation in Memphis, once he moved to the bullpen, he has been magic. 16.1 innings pitched, 6 hits, 1 walk, 1 earned run.
