San Francisco ? The federal prosecutor overseeing an investigation of steroids in baseball said Monday a newspaper report that five players, including Roger Clemens, had used illegal performance-enhancing drugs contained “significant inaccuracies.”

Citing sealed court filings, the Los Angeles Times reported that former pitcher Jason Grimsley had named Clemens, his Houston Astros teammate Andy Pettitte, and Baltimore Orioles Miguel Tejada, Brian Roberts and Jay Gibbons. The story first appeared on the Times’ Web site Saturday.

San Francisco U.S. Attorney Kevin Ryan issued a statement Monday, saying: “In view of the recent news reports purporting to identify certain athletes whose names had been redacted from the government’s search warrant filings in the Grimsley matter, and in the interests of justice, please be advised that these reports contain significant inaccuracies.”
