David Robertson is hopeful he can return to the Philadelphia Phillies for the NLCS.

Robertson, 37, suffered a calf injury while jumping in the air to celebrate Bryce Harper's home run against the St. Louis Cardinals in Game 2 of the NL Wild Card Series last weekend.

"It was an awesome home run," Robertson said. "I just didn't stay within my limits. It's embarrassing, but I'm not going to lie to you guys. I'll tell you the truth. That's how I hurt it."

The reliever has six saves and a 2.70 ERA in 22 games for Philadelphia after coming over in a trade with the Chicago Cubs.
