Marty Castillo hit one of the most improbable home runs in World Series history, a two-run shot against Tim Lollar of the San Diego Padres in Game 3 of the 1984 World Series. It's not that Castillo did not have power - he hit 8 homers in 352 career at-bats in the big leagues, but that it was a highly unlikely turn of events that he was even in the starting line-up for that game. Nominally the third-string catcher of the Detroit Tigers, he only had 155 at-bats for them in 1984, his second season, hitting .234. He started only 14 games at third base all year, and was behind Howard Johnson and Tom Brookens on the team's depth chart, while Darrell Evans and Barbaro Garbey also saw playing time at third base. However, during the postseason, manager Sparky Anderson played a hunch and gave Castillo a few starts at third base, while benching Brookens and Johnson (Evans also saw some action at the position). Castillo responded by going 2 for 8 with a pair of RBIs in the ALCS, including driving in the only run of Game 3 by beating out a potential double play grounder against the Kansas City Royals. He then went 3 for 9 with that key homer which broke a scoreless tie with the two teams even at one game apiece in the World Series. The Tigers never looked back after his clutch hit, winning that game, 5-2, and the next two to dispose of the Padres easily. That was about it for Castillo's major league career however. He had hit below .200 in 1983, and hit a mere .119 in 57 games - and only 87 at-bats - in 1985 to conclude his time in the Show.
In 1989, Marty Castillo played for the Fort Myers Sun Sox of the Senior Professional Baseball Association. He hit .291 in 43 games with the team. In 1990 Marty again played for the Fort Myers Sun Sox and batted .232 in 24 games before the league folded.
