LOOK AT THESE BREAKING BALLS!!!!!
Gerrit Cole's pregnant wife showed off her ridiculous arm this week ... displaying some filthy, off-speed pitches in a quarantine bullpen sesh with the Yanks ace -- and yeah, the stuff is GOOD!!
Cole and his wife, Amy, have been getting in some games of catch during coronavirus isolation ... but they decided to turn things up a bit this month.
Amy toed a makeshift rubber and threw lasers at Gerrit ... and we're so glad the camera was recording -- because you might not see better curves and sliders all season long!
