Andrés Péres Thomas (born November 10, 1963) is a former professional baseball player who played in the Major Leagues primarily as a shortstop for the Atlanta Braves from 1985-1990. He batted and threw right-handed. Thomas brought a power bat to the shortstop position for the Braves (13 HR each in 1988 and 1989); however, he struck out quite a bit (95 Ks in 1988) and walked only 59 times in five seasons. His free-swinging prompted then-Braves' broadcaster Don Sutton to ask hypothetically during games, "Why would you even throw him a strike?" He was also an erratic fielder, leading all NL shortstops with 29 errors in 1988.
He was the manager of the Detroit Tigers' affiliate in the Dominican Summer League for 2006.
