Yoervis Medina's Knee-Buckling Curve

Nasty.

Yoervis Medina has been an asset in the Seattle Mariners' bullpen this season, posting a 2.29 ERA in 39.1 innings pitched. The knee-buckling, 86-MPH knuckle curve Medina delivered to Alexei Ramirez last night illustrates why he's enjoyed so much success. The pitch was pure filth, and when guessing fastball, unhittable. Ramirez's reaction was priceless.
