Curtis Granderson still hasn’t swung a bat in his rehab from a broken right forearm, and until that happens, he can’t do more than guess about when he will be back on the field in The Bronx.

For now, he continues to throw and shag balls in the outfield.

“Swinging was something that could happen,” Granderson said yesterday at Yankee Stadium before the series finale against the Orioles. “The timetable of when is still to be determined. After further consultation with the doctors and trainers, they decided to make sure I’m good throwing before I start to swing.”

Though there is hope Granderson could be with the team by May 1, neither he nor manager Joe Girardi is ready to put a date on anything.

“Since he’s not swinging a bat yet, I think [May 1] may be a little quick,” Girardi said. “We’ll just see how the rehab goes. ... Until he swings a bat we’re really not going to have a date.”

Granderson said when he rejoins the team he is prepared to begin wearing a guard on his right arm to prevent further injury.

“I’ve broken three bones, all due to pitches,” Granderson said of injuries suffered in 2005, 2008 and this spring. “It’s about time to cover up. They’ve all been minor injuries, but it’s something to keep in mind, considering it’s my throwing hand. I might as well protect it.

“It’s just something I’ve never done. As long as I feel comfortable doing it, I’ll do it.”

The most recent fracture was more than “minor” — Granderson has been sidelined for nearly two months after being hit by a pitch thrown by Toronto’s J.A. Happ in his first at-bat of spring training.

The timing of the injury, while minimizing the number of regular-season games lost, could add time to his rehab.
