NEW YORK -- If you see Curtis Granderson hesitate slightly on batted balls, there is an explanation: The center fielder is still adjusting to playing in the new Yankee Stadium.

Granderson said on Friday that he has had some difficulty tracking balls off the bat, and he is not alone. The Angels' Torii Hunter told Granderson before Thursday's game that he had the same issue on Tuesday and Wednesday.

"I was trying to figure out what it was, and I'm still trying to put my finger on it," Granderson said. "It's an adjustment, partly because we didn't get a chance to get a workout day here. We jumped right from the start of the season.

"Hopefully, when we get more games in the outfield, it will be a little different, but I didn't really notice the issue coming over here last year. It could be the wind, it could be the early part of the season, it could be that I haven't been here since July."

Early last season, the talk was about wind tunnels carrying balls out on a jetstream, and it remains to be seen what this year's verdict will be. There was speculation that the demolition of the old Yankee Stadium might affect the flight of fly balls, and though it's much too early to tell, Granderson's first three April games here piqued his curiosity.

"The wind is doing some interesting things," he said. "I think some balls that were hit to the outfield -- Hideki Matsui's ball [in the second inning on Thursday] was interesting. I knew he hit it well, and I thought I would possibly be able to make a play on it, and then it ends up going over the fence.

"Then I watched the balls that Nick Swisher hit to center field [in the eighth inning], Marcus Thames' ball that he absolutely crushed [in the second inning], and they ended up being caught and hitting the fence."-- Bryan Hoch

Yankees place Park on 15-day disabled list

NEW YORK -- Right-hander Chan Ho Park has been placed on the 15-day disabled list with a low-level strain of his right hamstring, and the club has recalled left-hander Boone Logan from Triple-A Scranton/Wilkes-Barre.

Park felt his hamstring tweak while warming up during New York's 6-2 victory over Los Angeles on Thursday. On Friday, he was sent to team physician Dr. Christopher Ahmad and had a MRI while the club debated whether to place him on the DL.

"There's a possibility that he would have pitched for us next week, but you run your bullpen short and you take the chance of hurting him worse," manager Joe Girardi said.

Park experienced right hamstring issues last September while with the Phillies but healed in time to join the club for the National League Championship Series and World Series, during which his pitching piqued the Yankees' interest.

Girardi said that Park might have been ready to pitch as soon as next week for the series at Oakland, but the prior hamstring issue influenced the decision.

Park felt that he might have been able to pitch in three or four days but understands why the Yankees want to be cautious.

"It's not really hurt. It's just a little sore," Park said. "They asked me to just think about the DL for 15 days and I'll be 100 percent ready. That's the idea."

Logan, 25, had a 1.35 ERA in three appearances at Triple-A after making a strong bid to open the year on the Yankees' roster as a second lefty to complement Damaso Marte.

Girardi said that a mechanical adjustment Logan made involving his leg kick, which is now more straight up and down over the rubber, helped his velocity and consistency this spring. In 10 1/3 Grapefruit League innings spanning 10 appearances, he had a 1.74 ERA.

"He pitched extremely well for us," Girardi said. "He just happened to be in a situation where we have an extremely deep bullpen. I think he would have been on a lot of other clubs, the way he pitched in Spring Training. This is an opportunity for him, and it gives us another left-hander, but I will use him against right-handers as well."

Girardi has been trying to sort out his bullpen mix over the first nine games, and Park's injury tosses in a new wrinkle. No longer can the Yankees ask three innings of Alfredo Aceves, for example, knowing that Park would be available to pitch a longer outing the next day.

"It changes it a little bit," Girardi said. "It gives guys different opportunities now in some of those innings." -- Bryan Hoch

Sabathia, Cervelli becoming a dynamic duo

NEW YORK -- After nearly calling a no-hitter last Sunday in St. Petersburg, Francisco Cervelli was back behind the plate and teamed again with CC Sabathia on Friday.

Jorge Posada caught all three games of the Yankees' series with the Angels, and, with a day game on Saturday after a night game on Friday, manager Joe Girardi decided it was the best time to give his regular catcher a day off.

"[Posada] got beat up a little last night -- got a foul tip off the mask, foul tip off the foot, which is kind of the usual day for a catcher," Girardi said. "It was more of a 'three days in a row, give him a day, start him the next two.' "

It doesn't hurt that Cervelli and Sabathia worked so well together the last time out. Sabathia pitched 7 2/3 scoreless innings, leaving only after he allowed his first hit, to Kelly Shoppach in the eighth.

In 11 career games with Cervelli, Sabathia has a 2.43 ERA, and opponents are hitting only .182 off him.

"Since Day 1, he's open with me," said Cervelli. "He never treated me like a rookie. Like [I'm] a veteran catcher, he tells me, 'Do what you have to do. I'll follow.' "-- Tim Britton

Worth noting

Robinson Cano and Derek Jeter have each hit safely in the Yankees' first 10 games of 2010. According to the Elias Sports Bureau, they are the first pair of Yankees teammates to accomplish the feat. Jeter and Hideki Matsui were the most recent teammates to hit in New York's first nine games, in 2006. ... Prior to Cano, the last Yankee with six multihit games through the club's first nine games was Alfonso Soriano in 2003, according to Elias. ... Saturday will mark the 59th anniversary of Bob Sheppard's first game as Yankee Stadium's public address announcer, which was also Mickey Mantle's first Major League game.-- Bryan Hoch
