NEW YORK (AP) — Alex Rodriguez and the New York Yankees are not seeing eye to eye on his hip injury.
The third baseman tweeted Tuesday night that his hip surgeon has cleared him to play in rehabilitation games, a move that angered Yankees general manager Brian Cashman, according to ESPN.com.
"You know what, when the Yankees want to announce something, (we will)," Cashman told the website.
"Alex should just shut ... up," the GM said, punctuating his comment with a profanity.
Cashman added that he planned to get in touch with Rodriguez right away, ESPN.com reported.
The general manager did not respond to calls from The Associated Press.
Rodriguez had left hip surgery on Jan. 16 and has been working out since May at the Yankees' complex in Tampa, Fla. The three-time AL MVP took swings in a simulated-game situation for the first time on Monday.
On Tuesday night, he tweeted the message, "Visit from Dr. Kelly over the weekend, who gave me the best news - the green light to play games again!" along with a photo of himself and Dr. Brian Kelly, who performed the operation in New York.
Cashman recently said Yankees doctors have not yet cleared Rodriguez for minor league rehab games.
"I don't tweet, and I really don't follow Twitter. So I probably don't really know much of what is going on. As far as I know he has not been cleared," Yankees manager Joe Girardi said Tuesday night after his team's 4-3 victory over Texas.
"There's always a chain of command with injuries. There has to be and that's the process. It goes through our training staff, our doctors and our GM and then it goes to me. I'm down on the totem pole."
New to the social media site Twitter, Rodriguez sent his first tweet on May 31.
Before the game — and Rodriguez's tweet — Girardi said Rodriguez "is making progress, which is good."
"He's in sim games until they decide he's ready to go out on a rehab. It's not yet," the manager said.
Rodriguez is expected to return to the Yankees around the All-Star break, shortly before he turns 38.
A-Rod has been in the news a lot even though he has spent almost no time with the team this season. He is among the 20 or so players who may be disciplined by Major League Baseball for their links to the now-closed Miami anti-aging clinic, Biogenesis of America. MLB could possibly seek a 100-game suspension.
Rodriguez admitted in 2009 that he used performance-enhancing drugs while with the Rangers from 2001-03. As baseball's highest-paid player with a $28 million salary this year, he would lose $7.65 million during a 50-game ban.
