Curtis Granderson is taking a big step in coming back from a fractured right forearm early in spring training.

Granderson is scheduled to play for Triple-A Scranton/Wilkes-Barre Thursday night, and though manager Joe Girardi didn’t put a timetable on Granderson’s return to the big leagues it’s possible the power-hitting outfielder could join the Yankees Tuesday when they open a six-game home stand against the Mariners.

Granderson has been limited to extended spring training games, so jumping to the highest level of the minor leagues is a big step.

“He is a big bat for us, it would mean a lot,’’ Girardi said before the Yankees’ 3-2 win over the Rockies Wednesday night at Coors Field. “When he is ready he is ready. I am not going to put a date on it. Let’s see how he feels in the box.’’

As he has been doing in the extended spring program, Granderson will play all three outfield positions for SWB.

* If shagging batting practice fly balls takes Mariano Rivera to the left-center field warning track in Kauffman Stadium this weekend, baseball’s all-time saves leader isn’t going to shy away from the area where he collapsed last May 3 and suffered a torn right ACL that required season-ending surgery in June.

“Nothing will change, I will do what I love to do,’’ said the 43-year-old Rivera, who is a perfect 12-for-12 in save chances.

Rivera, who missed the final five months of last season, said he is looking forward to being at Kauffman Stadium again.

“I will thank the Lord for me being there,’’ Rivera said. “I want to see the doctor who took me to the hospital and say ‘Thank You.’ I am not going to feel sorry. I feel joy. There is nothing to regret. I might be in the same spot.’’

Wednesday night, the Rockies gave Rivera a $5,000 check for his foundation in a pre-game ceremony. As he has done in other stops, Rivera met with long-time workers at Coors Field before the game.
