Jason Hammel got a laugh at Anthony Rizzo's expense Wednesday night after the Chicago Cubs' first baseman mistakenly congratulated Hammel on earning his first National League win.

Hammel, who beat the Pittsburgh Pirates in his Cubs' debut on April 3 and won 27 games with the Colorado Rockies from 2009-11, shared Rizzo's mistake with the media.

Although Rizzo tried to downplay his gaffe, Rizzo is getting payback on left-handers who limited him to a .189 batting average last season.

Rizzo collected three of his four hits against left-handers Wandy Rodriguez and Justin Wilson to raise his batting average against left-handers this season to .388 (7 for 18).

“Even in batting practice, he's working the other side of the diamond," manager Rick Renteria said. "He’s getting more and more comfortable with two strikes. The offense has peaks and valleys. Right now he’s in a good place. The shift doesn’t hurt him.
