FanGraphs.com's Joe Pawlikowski analyzes Luke Gregerson's slider. "The Padres’ bullpen has benefitted greatly from Gregerson and his slider. The unit claims the NL trifecta of fewest walks, most strikeouts, and lowest batting average against. They’re getting help from everywhere, but Gregerson has been a particular bright spot this season. The high slider frequency does cause a little concern, but for right now it’s his nearly unhittable weapon. I can’t imagine being an opposing hitter and standing in to face him. "
