LOS ANGELES (AP) — The San Antonio Spurs have grabbed a 3-2 lead in the NBA’s Western Conference quarterfinals by downing the Clippers 111-107 in Los Angeles.

BALTIMORE (AP) — The rioting in Baltimore is prompting the Orioles and Chicago White Sox to play Wednesday’s game in what is believed to be the first contest without fans in major league baseball’s 145-season history. The unrest caused the first two games of the Orioles-White Sox series to be postponed and will lead the Birds to play their three-game weekend series against the Rays at Tropicana Field instead of Camden Yards. Schools were closed Tuesday and the mayor imposed a 10 p.m.-to-5 a.m. curfew following Monday’s riots a few miles northeast of Oriole Park.
