Joe Kelly threw a football to improve his curveball
Joe Kelly has impressed onlookers in Cardinals camp with his improved curveball and Derrick Goold of the St. Louis Post Dispatch writes that the right-hander credits throwing a football during the offseason for the change:
Kelly stepped into the Cardinals’ rotation down the stretch last season and was fantastic, going 9-2 with a 2.09 ERA, but St. Louis’ impressive starting pitching depth means he’s not even guaranteed to be a starter this season. Goold notes that Kelly is one of seven starters competing for four openings behind Adam Wainwright, so that’s where the improved curveball could factor in.
And, really, Sam Bradford’s gripon the Rams’ starting job can’t be that secure anyway.
