Peralta has had an excellent postseason thus far, batting .333 with three home runs, five RBIs, and five runs in addition to playing excellent defense. Peralta only hit .239 with 13 home runs, 63 RBIs, and 58 runs during the regular season, but his earned his money in the playoffs.
The initial thought was the Tigers would prefer a shortstop with greater range to pair with third baseman Miguel Cabrera. But with a limited free-agent market and Peralta's postseason performance the Tigers have decided to pick up his option rather than give him a $500k buyout.
The Tigers went 88-74 on the season, winning the AL Central. They beat the Oakland Athletics and New York Yankees to win the American League Pennant. Currently they trail the San Francisco Giants 1-0 in the World Series.
