Castillo struck out four batters in five innings in a no-decision against the Cubs on Saturday. He walked five and gave up six hits, but allowed only one run.

Castillo didn't have a single clean inning but nevertheless escaped without major damage. He got out of a bases-loaded one-out jam in the top of the first inning by getting Kyle Schwarber to ground into a double play, setting the tone for a shaky outing. In all five innings, he managed to strand a runner in scoring position, but only once did he allow a runner to cross the plate. It certainly wasn't a spectacular performance, but it served to bring the young righty's ERA down to 5.61. He'll next take the hill Thursday against the Pirates.
