The dire forecasts late in spring training for Mark Teixeira’s 2013 season – when he returned to Tampa from the World Baseball Classic and faced possible season-ending surgery after he was diagnosed with a partially torn tendon sheath in his right wrist — have since given way to a sunnier outlook.

The first baseman said in the visiting clubhouse at Progressive Field Thursday that he “feels really good” and “could not be happier” with his rehab program. Teixeira added that if Dr. Melvin Rosenwasser, the Yankees’ hand specialist of choice, clears him on Friday, the switch-hitter will start swinging the bat.

“I’m pretty comfortable he’ll let me do that,” Teixeira said.

Teixeira said if all goes well, he will take batting practice in Toronto when the Bombers begin a three-game series there starting April 19, and then play in extended spring training games in Tampa when the team is there the following series.

“If that goes well, I’ll stay in Tampa,” Teixeira said. “I could do a couple simulated games, and I can get five, seven, nine at-bats every day.”

Joe Girardi seemed encouraged by Teixeira’s progress as well, but cautioned that taking hacks with a bat will be the “true steps.

“So far, so good. Everything has been positive in his rehab. The true steps are going to be in the swinging part,” Girardi said. “He’s been strengthening it, and he was in that brace for a while, but everything has been encouraging so far.”

Teixeira said he has not thrown a ball yet, but he believes his arm strength “will come back very quickly.”
