Duvall went 2-for-4 with a three-run homer, his 17th of the year, in Tuesday's 7-6 win over the Cardinals.

EDGE Analysis

He may not always put the bat on the ball (69 percent contact rate), but when he does, Duvall and his owners get their money's worth. The blast helped boost his slugging percentage to .622, second in MLB only to David Ortiz. There's no reason to believe his power won't continue considering he'd shown this same type of ability throughout his minor league career.
