Yu Darvish was acquired at the trade deadline so the he could make an impact in October. He was brilliant in the NLDS and NLCS, giving up a combined two runs and striking out 14 in 11.1 innings. Unfortunately, that success did not continue in the World Series.

Darvish didn’t make it out of the second inning in both of his World Series starts. He also gave up four runs and a home run in each outing. The Astros were teeing off of Darvish, and it’s all because he was tipping his pitches.

The reports first circulated not too long after the World Series was over. Eduardo Perez was on ESPN2 and broke down what he saw. You can watch his analysis below!

But now, we have proof from the source: a member of the Houston Astros. Tom Verducci of Sports Illustrated caught up with an unnamed player and received this information:

According to a Houston player, the Astros often knew what Darvish was about to throw by the way he brought the ball into his glove in the set position. (Darvish pitches exclusively out of the stretch.) The player said it worked like this: Darvish holds the ball at his side when he gets the sign from the catcher. Whether he re-grips or not as he brings the ball into his glove was the tip-off whether he was going to throw a slider/cutter or a fastball.

Like I said, the fact that Yu Darvish was tipping his pitches was reported quite a while ago. However, to hear it from a player on the Houson Astros is heartbreaking and frustrating all at the same time. The fact that nobody from the Dodgers’ camp caught this is very disappointing.

Ken Rosenthal recently reported that the Houston Astros are interested in Yu Darvish, and now we know why. They know exactly how he was tipping his pitches and thus know how to fix it.
