TAMPA, Fla. -- Yankees manager Joe Girardi responded Friday to Boston skipper Bobby Valentine's assertion Thursday night that Girardi's decision to call the 4-4 tie after nine innings was "not very courteous."

Girardi said he was not approached by the umpires nor asked if he had extra pitchers ready Thursday night, the same thing that happened under similar circumstances a night earlier.

"I've got to worry about our club," Girardi said. "The day before, I was approached in the eighth inning, did we have extra pitchers, when we were in Tampa. I wasn't approached last night. I've got to worry about our club and keeping our club healthy and not putting people in bad situations and making sure our club is ready to play. He has to do the same thing for his club. As I said before, I'm going to worry about our guys."

Girardi said he wasn't aware of what all Valentine said, but he said it would have been "acceptable" to play another half-inning if Valentine did indeed want Clayton Mortensen to pitch, as he claimed Thursday night. Valentine said Mortensen, who was set to pitch the 10th before the game was called, could have used that time to help compete for a roster spot. Mortensen was optioned to Triple-A Pawtucket on Friday.

"There was no communication, and usually there is," Girardi said. "And it's not like this is something new. There's a lot of times in Spring Training games end in the ninth inning.

"I'm worried about our club. I've had a few things to handle today that I'm much more worried about, and I'll continue to worry about my club."

Pettitte clears first live BP hurdle in comeback

TAMPA, Fla. -- Andy Pettitte's comeback reached another minor milestone Friday morning when he threw his first live batting-practice session on Field 2 at the Yankees' Spring Training complex.

Pettitte threw 35 warmup pitches, 26 more to batters and two pitchouts and reported that everything felt good, adding that even he has been "pleasantly surprised" by how well he's commanding his off-speed pitches already.

Pitching coach Larry Rothschild told the 39-year-old lefty that everything went "awesome" during his batting practice --- he was throwing downhill, keeping the ball down, maintaining the same arm slot on all his pitches and the ball was coming out of his hand well.

"I don't want to get over-excited because I haven't done anything yet. I expect to be back to where I was, or I wouldn't have come back," Pettitte said. "So, I'll be disappointed if I don't. I feel like I'm getting there. We'll see. I hope I continue to progress the way I feel like I am."

Pettitte called it a good first step, and the next one will be a light bullpen session Sunday -- a short side session just to keep his mechanics consistent -- before they decide when he will throw live batting practice again. He is still getting used to seeing the ball come off the bat, and it might take some time before his reaction time speeds up.

He also admitted his legs were "a little sore" Friday morning, but he had no problems on the mound after taking a dip in the hot tub and running. By the time he was done throwing, Pettitte said he felt like he could have thrown 10 or 15 more pitches. But the mantra with Pettitte remains "take it slow," and that's the reason he's not getting worked up about appearing in a Grapefruit League game before camp breaks.

"I'm just leaving it up to Larry to make out my schedule, and we'll talk after everything and see where we're at," Pettitte said. "I haven't set any goals. I know that they're saying they think I could be ready around May 1. That's what I'm shooting for."

Nova takes positive step in bid for rotation

TAMPA, Fla. -- Ivan Nova's pitching line Friday looked a little better than the ones he's put up in his previous Spring Training outings, but even that doesn't speak to how well Nova was cruising at times in the Yankees' 6-4 win over the Twins.

One of the four pitchers competing for three spots in the Yankees' rotation, Nova threw seven innings, allowed four runs on seven hits and struck out five, and his first four frames were perfect. The right-hander ran into trouble in the fifth and sixth, giving up two runs in each inning when manager Joe Girardi said Nova simply "lost his fastball," but left his sixth outing of the spring pleased overall.

"I'm happy with the way I threw the ball," Nova said. "The command that I had with my fastball, curveball, slider, especially the changeup today was unbelievable.

"Everybody's going to pitch good because everybody's feeling better. Everybody's got more command, and I know for sure the pitchers are working better than two weeks ago. I expect the guys to pitch well, too. I know it's a competition, but I want my teammates to pitch good and have good springs."

He sat down the Twins in order for four innings then gave up a leadoff double to Justin Morneau and a two-run homer to Josh Willingham in the fifth. He gave up two more hits that inning before escaping. He gave up two more runs in the sixth on a single to left by Sean Burroughs, but he came back with a perfect seventh inning.

"Seven innings, five of them were really, really, really excellent, then he had the two where he struggled a little bit," Girardi said. "I was happy with what he did."

Jeter plays three innings in return to lineup

TAMPA, Fla. -- Yankees shortstop Derek Jeter was back on the field Friday for the first time since March 14 after resting a sore left calf.

Jeter went 1-for-2 with a leadoff single to right field in the first inning and a double-play ground ball in the third. He said after the game he felt good, and he followed through on the original plan to have him play three innings.

"It's the same as when I came back last summer. It's good to be smart about it," Jeter said. "It is still Spring Training, but everything was fine."

Manager Joe Girardi said Jeter's next step will be playing five innings Sunday against the Tigers at home.

"I said, 'You were actually pretty smart today.' He didn't try to kill himself running to first, which is smart," Girardi said. "Give it a couple days to get going and then, as you feel comfortable with it -- he has no pain or anything, but when you feel confident that nothing's going to happen -- that's when you start going."

Bombers bits

• Right-hander David Robertson threw 29 pitches in a simulated game Friday morning, facing seven batters. Manager Joe Girardi said Thursday that Robertson could appear in a Spring Training game soon. Robertson has been out with a bruised right foot suffered when he missed a step on March 7.

• Right-hander D.J. Mitchell and catcher Austin Romine were named the winners of the Yankees' 2011 Kevin Lawn Award as the club's Minor League Pitcher of the Year and Player of the Year, respectively. They were honored prior to Friday's 6-4 win against the Twins at George M. Steinbrenner Field. Romine also won the award in 2009.

• Closer Mariano Rivera pitched a perfect inning with one strikeout against the Twins on Friday. He has thrown five scoreless innings in five spring appearances, racking up four strikeouts and allowing only one baserunner -- a hit batsman last Saturday.
