NEW YORK -- Manager Joe Girardi could smile after Wednesday's game, happy that Jorge Posada's ejection happened to come on the same day the Yankees expanded their roster to include third catcher Chad Moeller.

Posada was tossed in the eighth inning of the Yankees' 4-3 win while pinch-hitting for Francisco Cervelli. If Moeller hadn't been on the roster, Girardi would have been forced to use emergency catcher Ramiro Pena behind the plate and find someone else to play third base.

All that said, Girardi doesn't have a problem with the emotion Posada brings to the ballpark.

"Jorgie is an emotional guy, and that's one of the things we love so much about Jorgie, because he brings that intensity every day," Girardi said. "Sometimes with all that great intensity he brings to the field every day, sometimes things happen. But I don't want him to change what he's doing most of the time, because his personality is important to this club."

Girardi added that, had Moeller not been on the roster, Posada "probably" would have been smart enough to avoid an ejection.

"I talk about it with all our players in situations," Girardi said. "You've got to be smart. We can't afford to lose you. Suspensions don't do us any good."

Yankees to play five straight day games

NEW YORK -- Starting with Thursday's series finale against the Athletics, the Yankees will play five consecutive day games in the Bronx for the first time since April 2004.

The Yankees are playing day games wrapping around Labor Day weekend, much like they did earlier this summer for Independence Day. Thursday's day game is a traditional getaway afternoon game, allowing the Athletics plenty of time to fly back to Oakland for their next series with the Angels.

After a night game on Tuesday, the Yankees will host another day game against the Orioles on Wednesday.

Manager Joe Girardi said he doesn't have any issues with playing in the afternoon, so long as the temperatures aren't too high.

"It's not so much the consecutive ones unless it's really hot," Girardi said. "To me, it's when it's the night-day-night-day -- that's the hardest thing for a player. We have six out of seven [day] games, so we'll be able to get on a pretty good schedule."

Nick Swisher, though, isn't as excited about the scheduling quirk.

"Baseball should be played at night," he said.

The Yankees have enjoyed afternoon baseball all season, posting a 31-16 record in day games. That's good for second in the Majors, behind only Thursday's opponent. The A's are 30-13 under the sun in 2010.

Swisher day-to-day with left knee stiffness

NEW YORK -- Nick Swisher is day-to-day after departing the Yankees' 5-0 win over the Athletics on Thursday with stiffness in his left knee.

The pain is in the same spot where Swisher was hit by a foul ball in Toronto last week, causing him to leave one game and miss another.

He said he felt something in his knee again on Wednesday night going after a fly ball in right field. It was bothering him a bit in pregame warmups on Thursday, but he hoped to battle through it. He was pulled, however, after a first-inning groundout on which he limped out of the batter's box.

"He told me he just couldn't explode when he took off to run," manager Joe Girardi said. "He came in and iced a lot, and we'll see if he's able to go tomorrow."

Swisher was replaced in the top of the second by Curtis Granderson, who went on to hit two home runs and drive in three.

"I expected hopefully to come in later in the game, but you never know. You've got to be ready to go," said Granderson, who made a similar appearance last Saturday in Chicago replacing Mark Teixeira. "The good thing about today was I had a couple of at-bats prior to mine to get warmed up."

Swisher is hitting .295 with 25 home runs and 80 RBIs on the season.

Worth noting

Thursday is the Yankees' 48th day game, third in the American League behind only the Tigers (56) and Blue Jays (50). The Cubs, of course, lead all of baseball with 67 day games. ... The Yankees played five straight afternoon contests from April 8-14, 2004, against the White Sox and Devil Rays, going 3-2. ... New York's five-game winning streak is its best since the Yankees won seven in a row from July 3-9. It is the team's fifth winning streak of at least five games this season. ... The Bombers have won six in a row and eight of nine overall vs. the Athletics this season. A victory on Thursday would give the Yankees their best single-season mark against the A's since 1919, when they went 18-2 against the Philadelphia Athletics.
