A-Rod's struggles; injury updates

Alex Rodriguez has just one home run in his last 80 at-bats.

That's not exactly the definition of a power hitter.

Joe Girardi addressed Rodriguez's power outage before Saturday's game.

"He's not driving the baseball as consistently as we've seen him do in the past," Girardi said. "But as I've said, home runs become very streaky and all of a sudden you put up eight in a month and you're right where you should be at. And I think he's capable of doing that."

On the season, A-Rod has five homers and four doubles in 140 at-bats.

ROBERTSON UPDATE: David Robertson (strained left oblique) still hasn't picked up a baseball since the Yankees put him on the disabled list on Tuesday. Girardi said that, as of Thursday, Robertson was still feeling discomfort in his side and he will be re-evaluated at some point in the next few days.... Brett Gardner (right elbow strain) will be evaluated after Saturday's game.

AN EYE ON NOVA: Girardi said he will keep a close eye on Ivan Nova, who is starting Saturday after suffering a sprain of his right food and ankle in his last start.

Girardi said he'll check with pitching coach Larry Rothschild to see if Nova favored his left side during warmups and will watch throughout the game to see if "it's a problem."

If Nova struggles, Freddy Garcia and David Phelps are available.
