Baseball union head Donald Fehr rejects the suggestion many players are under suspicion because 104 of them tested positive for drug use in 2003, including Alex Rodriguez.
The testing was confidential until Rodriguez's results were leaked to a reporter. Pitchers Curt Schilling and Brad Lidge are among those who have said all players who tested positive should be identified because otherwise everyone who played in 2003 is suspect.
"If that's the judgment, it seems to me that is entirely wrong," Fehr said Monday. "We know what happened in 2003. The number of positives we had was slightly over 5 percent. That means that slightly over 94 percent was negative."
Fehr is beginning his annual tour of spring training camps.
