The1990Chicago White Sox season was the White Sox's 91st season. They finished with a record of 94–68, good enough for second place in theAmerican LeagueWest, 9 games behind of the first placeOakland Athletics, as the White Sox played their final season at the agingComiskey Park before moving to the newComiskey Park the next season.

In the summer of 1990, Michael Jordan took batting practice at Comiskey Park.^[1] The following year, Upper Deck created a baseball card of Michael Jordan and it was numbered SP1.^[2]

The White Sox andTexas Rangers were involved in the longestrain delay in baseball history at 7 hours and 23 minutes at Comiskey Park on August 12. Behind the delay's length was the White Sox's insistence that the game be rescheduled at Comiskey four days later when both teams were idle and not atArlington Stadium the subsequent weekend, which was rejected by the Rangers. Thegamesmanship between the two sides resulted in the contest eventually played as part of atwi-night doubleheader at Arlington on August 17.^[3]

Bobby Thigpen had the best season of his career in 1990, setting the major league record of 57 saves. He also maintained a 1.83 ERA and was named to the AL All-Star team. He also blew eight saves that season, including two three-run leads.

In anticipation of the move tonew Comiskey Park, the White Sox on July 2 unveiled new team colors ofblack andsilver and uniforms based on the ones worn in1959 and theearly-1970s featuring a return ofpinstripes to the home version.^[4] The uniform ensemble was originally scheduled to debut thefollowing season, but its popularity with the fans resulted in the White Sox officially making the change beginning with the opening game of its final homestand of the campaign on September 25.^[5] The ballclub instantly jumped to the top of MLB merchandise sales.

• July 1, 1990 –New York Yankees pitcherAndy Hawkins threw a no-hitter against the Chicago White Sox and lost the game. A scoreless game until the bottom of the 8th inning, Sammy Sosa started the rally by hitting a ground ball that Yankee third basemen Mike Blowers bobbled. Initially it was ruled a hit. Yankee manager Stump Merrill was standing on the top of the dugout steps barking up in the direction of the press box. Quickly the play was changed to an error on Blowers. Sosa then stole second base. Ozzie Guillén and Lance Johnson both then drew walks to load the bases. The next batter, Robin Ventura hit a fly ball that eluded Yankees left fielder Jim Leyritz allowing three unearned runs to score. The next batter, Iván Calderón, then lifted a fly ball to right field that was dropped by Jesse Barfield making the score 4–0.

On July 11, 1990, as part of the celebration of Comiskey Park, the White Sox played a Turn Back the Clock game against theMilwaukee Brewers. The White Sox wore their 1917 home uniforms. This was the first Turn Back the Clock game in the major leagues and started what has become a popular promotion. The club turned off the electronic scoreboards and public address system. They constructed a special manually operated scoreboard in center field for the day and even the grounds-crew wore period costume. General admission tickets were sold for $0.50, popcorn was a nickel, and the stadium organ was shut down for the game.
