With quick turnaround, Yanks opt to sit A-Rod

NEW YORK -- At 10:30 a.m. ET on Saturday, Alex Rodriguez addressed the media for the first time since returning to Yankee Stadium. He talked about how "awesome" it was to be back in New York, how "amazing" it was to be back in front of the home crowd.

Twenty minutes later, the Yankees posted a lineup without his name on it.

After playing four games in five days since coming off the disabled list on Monday, the Yankees' third baseman is getting a day off against Tigers right-hander Anibal Sanchez. The start of Friday night's game was delayed 47 minutes and didn't end until almost midnight, so manager Joe Girardi decided to keep Rodriguez out of Saturday afternoon's lineup.

"It's a quick turnaround," Girardi said. "He's coming off an injury, and I'm just trying to manage it and keep him on the field the rest of the year."

Days off are part of Girardi's plan to keep the 38-year-old Rodriguez fresh coming off his second hip surgery. He also pulled Rodriguez in favor of a defensive replacement -- Jayson Nix -- to start the ninth inning on Friday.

Nix started at third base, batting eighth against Detroit on Saturday.

"It's a day-by-day [plan]," Girardi said. "If we don't have that late night, maybe I play him today. It would have been his first day game after a night game. I'm just trying to be proactive in this, and make sure we don't run him into the ground where he ends up hurting something else."

"I trust Joe," Rodriguez said. "He's going to do the best for me and for the team."

Rodriguez's first home game of the season on Friday brought a mixed reaction from the fans. The sellout crowd serenaded the controversial third baseman with a raucous mixture of cheers and boos each time he came up to bat.

Despite the mixed reaction, Rodriguez called Friday "a day I'll never forget."

"It was awesome. It was just an amazing experience," Rodriguez said. "The fans were incredible. Such great energy. Such a great response. It was pretty overwhelming. I was having a hard time keeping my emotions in check."

Rodriguez struggled on the emotional night, going 0-for-4 with three strikeouts in the Yankees' 4-3 walk-off win. Still, he said, Friday went "so much better than I ever dreamed of."

As for the booing, that's something he's already used to. He expects to hear that for the rest of the season, especially next weekend.

"Well, for the last 14 years, there's always been a mix," Rodriguez said. "Even Chicago was a mix. Boston is going to be a mix -- well, maybe Boston isn't going to be a mix. But I was overwhelmed."

Running next up for Jeter on road to recovery

NEW YORK -- Yankees captain Derek Jeter expects to resume running next week as he works to return from his third stint on the disabled list this season.

Jeter played catch on the field at Yankee Stadium on Saturday and said that his strained right calf "feels great." He said that he would ride the stationary bicycle in the Yankees' clubhouse during the team's game against the Tigers, and expects to stay with the Bombers through the homestand.

"I would assume I'm going to run soon, but I don't know," Jeter said. "All I know is what I'm doing today. I've got to go ride the bike. But I would assume [I will run] in the next couple of days."

Jeter was placed on the disabled list retroactive to Aug. 3 and said he expects to be activated when eligible. He has played in just five games this year.

"I'm confident I'll be ready," Jeter said.

Yet another stint on the disabled list has given Jeter the unwanted problem of too much time to kill. He was a guest this week on NBC's "Late Night with Jimmy Fallon," where house band The Roots came up with three light-hearted suggestions for Jeter's walk-up music upon his return.

"It was funny, right?" Jeter said "I hadn't heard it before I went out there. The last one was good, the second one was funny."

A-Rod: Discipline from Yanks 'has not happened'

NEW YORK -- Alex Rodriguez said that he was unaware of a published report that stated he was issued a letter informing him of discipline by the Yankees before Friday's game.

Citing sources, ESPN New York reported that Rodriguez was hand delivered a letter in the clubhouse officially informing him that he would be penalized for seeking a second opinion on an injury without club approval.

"No, it has not happened," Rodriguez said on Saturday, adding, "Maybe they sent it to my lawyers. But I'm not really going to talk about that."

Yankees general manager Brian Cashman said that the team is not commenting on the situation.

Rodriguez went 0-for-4 with three strikeouts in the Yankees' 4-3, 10-inning win over the Tigers on Friday.

The Yankees have been expected to hand down some measure of discipline to Rodriguez following their public clash in late July over his strained left quadriceps.

Without the Yankees' knowledge or approval, Rodriguez enlisted the help of Dr. Michael Gross of Hackensack University Medical Center to examine an MRI.

Gross then appeared on WFAN, contesting the opinion of Yankees team physician Christopher Ahmad by stating that he saw no reason Rodriguez could not be playing. Gross acknowledged that he had never treated, nor met, Rodriguez in person.

Article XIII, Paragraph D of the Collective Bargaining Agreement states that players must "inform the Club in writing of his decision to seek a second medical opinion" prior to undergoing another evaluation.

ESPN New York also reported that the Yankees sent an official letter of discipline to catcher Francisco Cervelli for failing to report to work prior to the announcement of his 50-game suspension.

Bomber bits

• Rodriguez had the same reaction everyone else had to Tigers' third baseman Miguel Cabrera's home run last night: Awe.

"That guy, he's amazing. That was a joke," Rodriguez said. "Everyone thought he was dead. It was like the movies, you've got to shoot him to make sure he's dead. I knew he wasn't coming out of the game. I said, 'Don't fall for that bait of limping around.' He's a dangerous guy."

• On this day in Yankees history -- Aug. 10, 1986 -- former player and manager Billy Martin's Monument Park plaque was unveiled. His No. 1 is one of the Yankees' 17 retired numbers.
