"When I saw that first lefty step in there, it's like a comfort zone," said Varvaro. "I'm like, 'Here he is.' Then the next one, perfect. And then the third one, I'm like, 'Did they set this up to roll this way to really see [how I am against lefties]'? For some reason, I've pitched better against lefties. I don't want to say why I think that is so other people maybe catch on. I don't want to say it's a comfort zone, but I tend to have more success against lefties."
Last year, Varvaro held lefties to a .149 average while righties hit .273 against him. His career splits are similar, with lefties hitting .196 against him and righties registering at .262.
Varvaro enjoys being cryptic when asked for a reason.
"I don't want any lefties reading this article or anything, or trying to figure me out," said Varvaro.
The Red Sox were pleased to acquire the underrated Varvaro from the Braves for Minor Leaguer Aaron Kurcz and cash considerations.
"Once again, he was powerful and with good late action to attack both lefties and righties," said manager John Farrell. "Varvaro, I thought, was powerful."
