Another productive day in Tampa for Jeter, A-Rod

BALTIMORE -- It is possible that Derek Jeter could begin playing in Minor League rehab games before Alex Rodriguez.

Jeter and Rodriguez had another solid day of workouts at the Minor League complex in Tampa, Fla,. on Friday, and manager Joe Girardi said on Friday that he is not sure which player is closer to facing Minor League competition.

"I'm not sure who you'll see in a game first," Girardi said before the club's game at Camden Yards. "Alex has obviously had more simulated at-bats than Derek, but we'll see how that goes."

Both players spent time in the batter's box on Friday. Rodriguez had five simulated at-bats and ran the bases, hitting two batting practice home runs while also fielding ground balls and sliding on a mat in the outfield during his three hours at the complex.

Jeter had six simulated at-bats, which he also had on Thursday, marking his first time facing live pitching since March. He did not run the bases, but he took BP and fielded grounders on both grass and dirt.

Both A-Rod and Jeter faced 19-year-old Gulf Coast League right-hander Francis Joseph in their at-bats.

Jeter said, "Everything's good," as he departed the complex.

"I think what you think about is that they're getting closer to getting into games," Girardi said. "They're obviously seeing a lot of really young kids throwing at them, and you get a little nervous about that. But until they start getting into games, you don't really start thinking about it."

The Yankees have stuck to a vague timetable, saying that both are expected to return after the All-Star break.

The specifics of Rodriguez's situation, however are confusing. Rodriguez tweeted on Tuesday that he had been cleared to begin playing in rehab games, upsetting general manager Brian Cashman.

After stating that the tweet had been fueled by "pure excitement" about getting back on the field, Rodriguez reportedly backed off the statement in a telephone conversation with Cashman and team president Randy Levine, saying that he isn't actually sure when he could begin playing.

"I don't know who's going to be in a game first, and I don't know which one we're going to get back first," Girardi said.

Clerical error, nothing more, behind CC/Phelps switch

BALTIMORE -- The Orioles may have been surprised to see CC Sabathia instead of David Phelps on the lineup card for Friday's game, but the Yankees said there was no switch, just a clerical error.

Pitching coach Larry Rothschild said that Sabathia had always been scheduled to pitch against Baltimore on Friday, but he mistakenly gave the incorrect rotation to the Yankees' director of media relations, Jason Zillo, before the series.

Manager Joe Girardi said that both Sabathia and Phelps, who is pitching on Saturday, were aware of their correct days to pitch. Filling out crossword puzzles in the clubhouse, Phelps was amused to learn that he had briefly been the subject of speculation about a possible injury or trade.

"We felt like there was a good chance that [Sabathia] would pitch one of the three days, so it doesn't change anything about what we're doing," Orioles manager Buck Showalter said. "I finally just called Joe, and he said, 'Yeah, there was a miscommunication.' I said, 'Fine, thanks.' Short conversation."

Girardi also noted that right-hander Ivan Nova, who pitched well in a spot start against the Rays on June 23, is likely to pick up a start in the upcoming series against the Twins at Target Field.

"We're looking at the schedule day by day, and it kind of depends on if we need him [in relief]," Girardi said. "Our plan is to probably start him in a game in the Minnesota series. That could change."

Girardi still considers right-hander Adam Warren to be the regular long reliever, and he would like to be able to give some of his starters an extra day of rest as the Yankees attack a stretch of 20 games without an off-day.

"We're in an extremely long stretch of 20 games, and you start tacking on three or four starts in a row where it's on normal rest, we think that's pretty taxing," he said. "If during this time you can insert Nova one time -- or if you need to, twice -- we'll do it."

Bombers beat

• Catcher Francisco Cervelli caught two innings in a simulated game on Friday in Tampa, Fla., and is now holding his right hand -- fractured by a foul tip in April -- behind his back while catching. He also performed bunt-fielding drills but did not throw to bases.

• Outfielder Curtis Granderson (fractured fifth metacarpal of left hand) played catch and ran with a weighted sled attached to his back on Friday. He has not resumed swinging a bat.

• Entering play on Friday, outfielder Ichiro Suzuki had hit safely in each of his last 21 games at Camden Yards since April 5, 2008, batting .385 over that span.

• On this date in 1931, Celtic (of Glasgow, Scotland) defeated the New York Yankees of the American Soccer League, 4-1, in an exhibition game believed to be the first soccer game at the original Yankee Stadium.
