NEW YORK — Seattle Mariners minor league outfielder Jamal Strong, a former Husker, was suspended for 10 days Tuesday, making him the fourth player to test positive under major league baseball's new policy on performance-enhancing drugs.

Strong, who played 12 games for Seattle in 2003, was with Class AAA Tacoma, Wash., this season. The speedy leadoff man hit .235 with three RBIs through 12 games.

Strong, 26, was sent down to the minors in late March. He hit .324 with three homers, 24 RBIs and 19 stolen bases in 64 games for Tacoma last year.

In 2003, he went 0-for-2 in his time with Seattle. He missed half of that season after dislocating his left shoulder on a headfirst slide.

Texas minor league pitcher Agustin Montero was suspended for 10 days last week under the new policy.

Tampa Bay outfielder Alex Sanchez was the first player suspended under the new major league program, starting his 10-day ban on April 3. Colorado outfielder Jorge Piedra was suspended for 10 days starting April 11.
