Luis Castillo earns win Thursday

Luis Castillo allowed three runs on four hits over 5 2/3 innings with six strikeouts and three walks in a win on Thursday against the Astros.

Fantasy Impact

Castillo had allowed just one run over five innings. He tried to get through six, but a two-run double knocked him out of the game. It was still one of his better starts on the season. It is unclear what will happen next with Bryce Miller now healthy.

Luis Castillo takes loss Sunday

Luis Castillo allowed four runs on six hits over six innings with five strikeouts and two walks in a loss on Sunday against the Royals.

Fantasy Impact

Castillo had thrown three scoreless frames before running into trouble. He loaded the bases after hitting Salvador Perez before walking Carter Jensen with the bases loaded to bring in a run. He went to allow two more runs in the inning. Castillo's time in the rotation could be coming to an end when Bryce Miller is activated.
