Although injuries and age caught up to him to a degree – he hit just .257 with 12 homers in 377 at-bats in 1988 and .264 with 22 homers in 553 at-bats in 1989 – his veteran leadership was a significant factor in the A's consecutive World Series appearances. Parker signed with the Milwaukee Brewers for the 1990 season and had a solid year as the Brewers' DH, with a .289 average and 21 home runs in 610 at-bats. Milwaukee opted for youth, however, at the end of the year and traded the aging Parker to the Angels for Dante Bichette. Parker's last season was 1991. He played for the California Angels until late in the season when he was released. The Toronto Blue Jays then signed him as insurance for the pennant race, and Parker hit .333 in limited action. Since he was acquired too late in the season, however, he did not qualify for inclusion on the post-season roster and thus was unable to play in the American League Championship Series against the Minnesota Twins, which the Blue Jays lost in five games. Parker retired at the end of the season. Parker has served as a first-base coach for the Anaheim Angels, a batting coach for the St. Louis Cardinals in 1998, and a special hitting instructor for Pittsburgh. He owned several Popeye's Chicken franchises in Cincinnati until selling his interest in them in 2012 after 25 years. Parker never got more than 24% of votes on Hall of Fame ballots, and his 15-year Baseball Writers' Association of America eligibility was exhausted on the 2011 ballot. He can now be considered for the Veterans Committee Expansion from 2014. Supporters of Parker's Hall of Fame candidacy argue that Parker's involvement with the Pittsburgh drug trials has contributed to his not being voted into the Hall of Fame, which may have also harmed the candidacies of Keith Hernandez (who never received more than 10.8% and fell off the writers' ballot on his ninth try) and Tim Raines (debuted at 24.3%, but was elected on his tenth year on the ballot), serving as a precursor to those listed on the Mitchell Report not being voted into the Hall of Fame due to steroid abuse. Critics say that Parker's stats fall short of accepted standards of inclusion in the Hall. While Tim Raines became a cause célèbre among the sabermetric community which pushed for his election, Dave Parker does not fare as well when using advanced stats. Parker has had both of his knees replaced due to injuries from his playing career.
