Tracy finding his groove at the plate

D-backs first baseman delivering big hits in key situations

PHILADELPHIA -- First baseman Chad Tracy has played a crucial role in the D-backs' offensive surge over the past three games.

Tracy led the way with eight of Arizona's 39 hits over that span. His highlights have included a tiebreaking double in the 10th inning of Thursday's game against the Nationals and a two-run single in Saturday's eight-run fourth inning against the Phillies.

The first baseman missed the season's first two months recovering from right knee issues. His production over the past three games has raised his average from .275 to .303.

"He's seeing the ball well, and he's as good a hitter as anybody we have," manager Bob Melvin said.

The left-handed-hitting first baseman batted fifth Sunday against Philadelphia southpaw Cole Hamels and homered in his first at-bat in the second inning.

"His numbers were lower against left-handers," Melvin said of Tracy, who is a lifetime .222 hitter against southpaws, while hitting .308 against right-handers. "Any time he gets a lot of looks [against] righties and lefties and gets going, he can be a productive guy against either."
