The Mariners' Game 4 pitching plan unraveled -- and the effects could be lasting - ESPN

SEATTLE — Luis Castillo's smile was small and tight as he heard Seattle Mariners manager Dan Wilson tell him on the mound that he was being replaced. It was the third inning of Game 4 of the American League Championship Series, with the Mariners trying to hold off the Toronto Blue Jays, who had already won one game on the Mariners' home field. Castillo, who had thrown fewer pitches than he had in any of his 247 starts in the major leagues, nodded in assent — if not agreement — and handed the ball to his manager.

What happened before Wilson's decision was bad; what occurred after was worse. The Mariners' relievers failed to contain the Toronto offense, in an 8-2 loss, and with the series tied at two games apiece, Seattle will go into Game 5 with its pitching options even more complicated by how Wilson's choices played out.

Every postseason decision is evaluated through the prism of the result, which is not always fair but is October reality.

«You make decisions,» Wilson said after the game, «and you have to live with them.»

What the Mariners' staff had talked about going into Game 4, Wilson explained, was that Seattle wanted to be aggressive in going to the bullpen. When Toronto blew out the Mariners in Game 3, Wilson was able to hold back all of his best relievers: Gabe Speier, Matt Brash and Andres Munoz. Additionally, Bryan Woo — who had been Seattle's best pitcher before getting hurt Sept. 20 — would be available out of the bullpen, if Wilson found a suitable opportunity.

Castillo is a three-time All-Star, the most accomplished of the Mariners' vaunted rotation of starting pitchers, known for his sturdy reliability. He has also had a year of diminished stuff, with his swing-and-miss rate the lowest of his career;
