In case getting past the Dodgers’ Game 7 World Series loss to the Houston Astros wasn’t difficult enough, Manager Dave Roberts on Tuesday faced confirmation of their fears: that Yu Darvish was tipping his pitches in two of the Series losses.

An anonymous Astros player told Sports Illustrated that the way Darvish brought the ball into his glove let them know what was coming. The Astros scored nine runs against Darvish in 3-1/3 innings in Games 3 and 7.

When Roberts was asked about it during his media session on Tuesday at the Winter Meetings, he said the Dodgers had suspected as much.

“Wasn’t surprised,” Roberts said. “We had conversations about that with Yu and trying to kind of pin it down. Obviously, we weren’t successful.”

General Manager Farhan Zaidi told reporters that the Dodgers had plenty of people, including hitters, watching video after Game 3 to try to decipher how Darvish had been tipping his pitches.

Roberts said that, tipping or not, Darvish had other problems.

“I think that there’s something to (pitch-tipping), but there’s also a lot more for me to execution, where I think that you could view that there just wasn’t a lot of execution going on,” Roberts said.

By the time Darvish left Game 7, the Dodgers trailed 5-0 in the second inning, on the way to a loss that gave way to a long, hard winter.

“Gosh, I don’t know if you ever get over it,” Roberts said. “Especially you go to Game 7, and a lot of things could have been different, a pitch here, a pitch there, maybe change the outcome. But you still go through your mind and what you could have done possibly different to potentially influence it, but at the end of the day, it is what it is, and you learn from it.
