CLEVELAND (CBS/AP) More than a dozen steamy photos of all-star center fielder Grady Sizemore have made their way to Web sites across the Internet, but the Cleveland Indians star complains the shots were "stolen" from his girlfriend's e-mail and says that he is taking legal action.

Sizemore said that the nearly-nude pictures, including one where he is completely naked except for a tea cup covering his privates, were only meant for his girlfriend Playboy playmate Brittany Binger.

"These pictures were stolen illegally from my girlfriend's e-mail," Sizemore told The Cleveland Plain Dealer this weekend.

"It's now a legal matter that is under investigation. I can't say anything more."

Indians general manager, Mark Shapiro, said that he has not seen the pictures, but will "look into it," accodring to the paper.

The photos were taken with a cell-phone camera and show the major-leaguer alone, in various states of undress, in front of a bathroom mirror.

In some the shots he is fully clothed, and in others, he's wearing little to no clothing.

A Major League Baseball investigator contacted a number of the websites posting images this weekend and asked that they be taken down.

One of the sites still featured the shots Monday morning, but also posted the note from the official.

The message said the pictures were stolen from a personal computer and directed the site to preserve any related records in anticipation of a criminal complaint.

We fully support Grady as he deals with this personal matter," the Indians said in a statement Monday. "The posted photos were stolen from his girlfriend's e-mail account and a legal investigation is under way."

The 27-year-old Sizemore is the Indians' most popular player. His fan base includes "Grady's Ladies," and several other women's groups devoted to the three-time All-Star.

With a rare combination of speed and power, Sizemore has developed into one of baseball's best all-around players. He is one of only two players in club history to hit 30 homers and steal 30 bases in one season.

A two-time Gold Glove winner, Sizemore has endeared himself to Cleveland fans with his hustle and durability. In 2006 and 2007, he played in all 162 regular-season games, but he was limited to just 106 games last season.

Sizemore suffered an elbow injury and sports hernia during spring training in 2009 and was never 100 percent. He batted a career-low .248 with 18 homers and 64 RBIs before he deciding to stop playing on Sept. 4. He underwent two offseason surgeries.
