context: The 1989 offense got power from catcher/first basemen Bobby Cripps. Cripps hit 29 home runs and also led the Suns with 88 RBI and threw out 47 percent of would-be base stealers in 56 games behind the plate. Michael Young (baseball) batted .282 with 16 home runs and 86 RBI at second base. Two other future major league All Stars on the Suns that year were Vernon Wells and César Izturis. Wells batted .285 with 11 home runs and 65 RBI. Izturis meanwhile had a .262 average with a team-leading 20 stolen bases. John Sneed had one of the best seasons ever by a Suns pitcher, as he won a franchise record 16 games, while losing just 2, with a 2.56 ERA in 27 starts. He also collected 200 strikeouts in 161.1 innings pitched. Clayton Andrews returned from the 1997 squad and nearly matched Sneeds dominance. He went 10–7 with a 2.28 ERA and had 193 strikeouts in 162 innings pitched. The Suns closer was Jaron Seabury, who had a 1.65 ERA in 45 games with 17 saves. The Suns won the first-half division title and finished with the best record in the Northern Division. They made the playoffs and won in the first round, but did not advance to the championship because the league now had a three-round playoff format featuring 8 out of 14 teams. In the second round, the Suns would lose to the eventual league champion Greenville Drive.
