Castillo (6-8) was superb Sunday against the Phillies, throwing seven shutout innings against the Phillies. He struck out nine batters while allowing four hits and a walk.
The seven-inning outing was the deepest Castillo has worked into a game this season. "It was really nice that he went as deep as he did," interim manager Jim Riggleman said. "We would have been able to cover it if he didn't. I think more importantly, he sees he can do that. He can go through a tough lineup and get deep in a ballgame. He certainly didn't have to come out of the game there. He could have continued but we would have been stretching it a bit. It was very encouraging for him to go over 100 pitches and seven innings against that club." Castillo now has allowed just three earned runs over 17.1 innings in his last three starts, posting a 16:2 K:BB in the process. He'll look to continue one of his best stretches of the season next weekend against the Nationals.
