A teenage shortstop in the Texas Rangers' organization was suspended Friday for the first 50 games of next season after testing positive for a performance-enhancing substance under baseball's minor league drug program. Julio Gonzalez, 19, hit .253 in 27 games this season in rookie ball in Arizona. The penalty came a day after the Mitchell Report was released, looking at steroids in the major leagues. Gonzalez got the 30th suspension this year under the minor league program. There have been eight under the major league plan.
