Mariners' Luis Castillo: Brilliant in no-decision

Castillo did not factor into the decision Thursday versus the Guardians, yielding just one hit and no walks over six shutout frames in a 3-0 victory. He struck out six.

The only baserunner Castillo allowed on the night was a leadoff single by Will Brennan in the third inning which actually glanced off the pitcher's head and knocked his cap off, although the right-hander was fine. The incident clearly didn't spook Castillo, as he fanned the next three to get out of the frame and start a streak of 12 straight batters retired to finish off his night. He needed only 76 pitches to cruise through his six innings, collecting 13 swinging strikes and a 37 percent CSW rate along the way. The four-seamer was Castillo's most-used pitch in this one, just as it was after he came over to Seattle in a trade last August.
