Rockies catcher Wilin Rosario mashed three extra-base hits in Saturday's win over Philadelphia.

Rosario finished 3 for 4 with two doubles and a triple and he even added a rare walk. Rosario's on-base percentage is a poor .287, but the power hitting is nothing new. His .194 isolated power (slugging percentage minus batting average) ranks fifth among catchers.

Rosario called the issue a "water fungus." He's been wearing a protective sleeve on his arms all season due to the irritation.

Rosario was just 4 for 28 with one home run and three RBI in June heading into Thursday's game against the Nationals.
