Alex Rodriguez's troubles just got much worse than a sloppily administered steroid injection.

With Major League Baseball's investigators ramping up their probe following reports that "biochemist" Anthony Bosch had provided performance-enhancing drugs to Rodriguez and other players, a new report surfaced Friday saying Bosch provided A-Rod with special star treatment, including personally injecting the slugger with testosterone and human growth hormone.

According to an ESPN report, Bosch was summoned by Rodriguez to the third baseman's waterfront mansion on Biscayne Bay to administer injections of the performance-enhancing drugs.

"Only Tony handled A-Rod," according to a source in the report.

In one instance, however, Bosch "had trouble locating a vein" on Rodriguez and that the botched injection caused "bleeding everywhere," infuriating the Yankees star, according to the report.

A spokesman for Rodriguez quickly denied the ESPN report, telling the Daily News, "The allegations are not true." Rodriguez has also denied ever being treated by Bosch.
