Jose Canseco ROY 86, Mark McGwire ROY 87 and Walt Weiss ROY 88 Autographed 8x10 Photo (JSA). Comes with a certificate of authenticity from James Spence Authentication (JSA). Under the Haas ownership, the minor league system was rebuilt, which bore fruit later that decade as José Canseco (1986), Mark McGwire (1987), and Walt Weiss (1988) were chosen as A.L. Rookies of the Year. During the 1986 season, Tony La Russa was hired as the Athletics' manager, a post he held until the end of 1995. In 1987, La Russa's first full year as manager, the team finished at 81–81, its best record in seven seasons. Beginning in 1988, the Athletics won the A.L. pennant three years in a row. Reminiscent of their Philadelphia predecessors, this A's team finished with the best record of any team in the major leagues during all 3 years, winning 104 (1988), 99 (1989), and 103 (1990) games.
