Acker spent a decade pitching in the majors, posting a 33-49 record with 30 saves and a 3.97 ERA for the Toronto Blue Jays, Atlanta Braves and Seattle Mariners from 1983-1992. Primarily pitching in relief, his season high for wins was just seven, which came in 1985 for the Blue Jays. He also saved 10 games that year while recording a 3.23 ERA, making it his most productive season. He saved 14 games for the Braves in 1987 while pitching in an impressive 114 innings of relief. Acker reached the ALCS three times with Toronto and had a 0.69 ERA in 13 innings, but Toronto lost all three times, so he never made it to the World Series.
Acker was a member of the Blue Jays when Nolan Ryan pitched his seventh no-hitter on May 1, 1991 at Arlington Stadium in Texas. Ryan struck out 16 of Acker’s teammates, while walking two to lead the Rangers to a 3-0 win. Acker did not pitch in the game. Toronto’s Jimmy Key took the loss.
