Rays starter Tyler Glasnow gave the Astros an advantage they didn't need in Game 5 of the American League Division Series. He was tipping his pitches.
Houston scored three runs before Tampa Bay recorded an out in the first inning, and after Jose Altuve drove in a run with a single, he clearly looked to the dugout and was trying to communicate something.
A few minutes later after Alex Bregman doubled and scored on a Yuli Gurriel single, he was seen telling Carlos Correa something in the on-deck circle.
It's unclear if Altuve saw something in Glasnow's delivery or if Bregman caught something in the signals at second base, but clearly the Astros were tuned into what the righty was doing.
And Glasnow confirmed he was tipping his pitches after the game saying it was "pretty obvious" what he was doing.
Houston tallied four hits before recording an out in the game and lit up a man who held the Astros scoreless through four innings in Game 1.
The Astros are notorious for figuring out what pitchers are doing and taking advantage of it. In the 2017 World Series, they picked up something in Yu Darvish's delivery and lit him up in two starts including a Game 7 win.
And for what it's worth, free agent Trevor Plouffe suggested he knew all of Glasnow's pitches after one inning in spring training. So it does seem like this has been a problem for the pitcher in the past.
"I had his pitches this Spring Training," Plouffe wrote on Twitter. "Every one of em and it only took an inning."
