Joe Girardi said he doesn’t know when he will get Mark Teixeira or Kevin Youkilis back from the disabled list, but the Yankees manager reported Tuesday the first baseman and corner infielder are making progress. “He had four more [at-bats],’’ Girardi said of Teixeira’s participation in a simulated game at the Yankees’ minor league complex in Tampa Tuesday in which he batted only from the left side. “Youk had three at-bats. Everyone seemed to do a little bit more today. Tex is doing well; Youk is doing well. [Eduardo Nunez] took some tee and toss and Alex [Rodriguez] took some BP. It’s all good.’’ The next step for Teixeira (right wrist) and Youkilis (lower back) is to play in an extended spring game, but Girardi didn’t have a date when that would happen. Of the two, Teixeira appears to be closer to returning than Youkilis, but the June 1 goal of getting the switch-hitter back and in the middle of the lineup looks like a long shot at this point. In other news concerning injuries, Girardi provided updates on Ivan Nova (inflamed right biceps) and Michael Pineda (shoulder surgery). “Nova felt good and Pineda will probably start (in an extended spring game) Thursday or Friday,’’ Girardi said before the Yankees’ 3-2, 10-inning loss to the Orioles Tuesday night at Camden Yards. According to Girardi, Joba Chamberlain (right oblique strain) is scheduled to throw in a game today. Chamberlain has made one minor league rehab start and is likely to work in two more games before being evaluated to see if he is good enough to come off the DL.
