The Cardinals' starting rotation is doing quite well thus far, leading baseball with an aggregate 2.07 ERA. Their bullpen, on the other hand, brings up the rear at 5.67. They have lost Jason Motte for the season as the right-hander will undergo Tommy John surgery. Mitchell Boggs' stint at closer was short-lived as his 12.66 ERA in 10.2 innings earned him a demotion to Triple-A Memphis. Marc Rzepczynski, too, was demoted to Memphis with a 7.88 ERA. It's ugly.
