In a transaction requested by his old manager Dick Williams despite the objections of team owner
Charlie Finley, Andrews signed with the
Oakland Athletics on July 31, 1973. A part of the ballclub's postseason roster, he appeared in two games of the
American League Championship Series, entering both as a
pinch hitter.
In the second game of the
1973 World Series between the
Oakland A's and the
New York Mets, Andrews committed two errors in a four-run twelfth
inning, leading to a Mets' 10-7 victory. With two out in that inning and the Mets leading 7-6,
John Milner's ground ball went through Andrews' legs for the first error, allowing
Tug McGraw and
Willie Mays to score. One batter later,
Jerry Grote hit a ground ball to Andrews, whose throw to first pulled
Gene Tenace off the bag for the second error, which allowed
Cleon Jones to score. Oakland owner
Charlie Finley forced him to sign a false affidavit saying he was injured, thus making him ineligible to play for the rest of the series. Andrews' teammates and manager
Dick Williams rallied to Andrews's defense. Finally,
commissioner Bowie Kuhn forced Finley to reinstate Andrews. He entered Game 4 in the eighth inning as a pinch-hitter to a standing ovation from sympathetic Mets fans. Andrews promptly grounded out, and Finley ordered him benched for the remainder of the Series. Andrews never played another major league game, playing baseball in Japan in
1975 before retiring.
