CHICAGO (AP) — Jose Abreu hit a two-run homer, and the Chicago White Sox kept Kansas City out of first place in the AL Central with a 5-4 victory over the Royals on Saturday night.

The Detroit Tigers, who lost 12-3 at Minnesota on Saturday, stayed one game ahead of the Royals entering the final day of the regular season. Kansas City clinched at least a wild card spot on Friday.

Danny Duffy (9-12) lasted only two innings for the Royals. He allowed four runs, five hits and one walk. The White Sox jumped on him, scoring three runs in the first inning. Abreu capped the rally with his 36th home run.

Abreu broke a 31-year-old franchise record for the most homers in a season by a rookie, previously held by Ron Kittle. They are the most by a rookie since St. Louis’ Albert Pujols hit 37 in 2001.
