Luis Castillo deals six scoreless innings Monday

Luis Castillo allowed two hits over six scoreless innings with seven strikeouts and two walks in a no-decision on Monday against the Yankees.

Fantasy Impact

Castillo was showing his vintage stuff Monday night in Seattle. Coming off a down season, he gets off to this year on a strong note. He was in line for the win when he left the game, but the Mariners bullpen gave up the lead in the next inning. He is scheduled to face the Angels in his next outing.

Luis Castillo to pitch fifth game of season for Mariners

Luis Castillo will start on Monday against the Yankees.

Fantasy Impact

Castillo is really the No. 4 starter for the Mariners, but he is opening the season fifth in the rotation because the Mariners likely want Emerson Hancock to avoid the Yankees. Castillo doesn't hold the same upside he has once had, but he should continue to eat a lot of innings for the Mariners rotation.

Luis Castillo Dominates in Win Over Royals

Luis Castillo tossed a stellar six innings, allowing just three hits and no walks while striking out three in Thursday's victory against the Royals.

Fantasy Impact

After today’s performance, Castillo now holds a 3.63 ERA and 1.23 WHIP with 10 wins and 8 losses across 31 starts this season. It's been a bit of a down season by Castillo's standard, but he has been servicable for fantasy managers. He's compiled 17 quality starts to give managers volume, but his strikeout rate is the lowest of his career. He'll look to close out his regular season next week against the Rockies.
