Monday night's game between the Kansas City Royals and White Sox in Chicago was postponed due to rain. The teams will play a straight doubleheader on Tuesday starting at 3:40 p.m. CT.

Kansas City right-hander Brady Singer (8-10, 5.34) will start against Chicago right-hander Dylan Cease (6-,7, 4.98) in the opener. Royals righty Jordan Lyles (4-16, 6.24) will oppose White Sox righty Touki Toussaint (3-6, 4.70) in the nightcap.

The Royals entered Monday with the worst record in the majors at 44-100. The White Sox, at 55-88, have the fourth-worst record in MLB.

Both AL Central rivals have been mathematically eliminated from the postseason.

Earlier on Monday, the White Sox recalled right-hander Deivi Garcia and catcher Carlos Perez from Triple-A Charlotte. Chicago optioned outfielder Oscar Colás and righty Edgar Navarro to the farm team.

Colás made the White Sox opening day roster and was slotted as a regular in right field. But the 24-year-old Cuban batted just .216 with five homers and 19 RBIs in 75 games and, despite talent, still needs to work on baseball basics and reducing mistakes.
