U.S. beats El Salvador in Gold Cup quarterfinals

Omar Gonzalez and Eric Lichaj scored late in the first half Wednesday night and the United States beat El Salvador 2-0 in a Gold Cup quarterfinal at Philadelphia in which El Salvador defender Henry Romero appeared to bite Jozy Altidore on the back of a shoulder.

Canadian referee Drew Fischer, a Major League Soccer regular, didn’t penalize the incident, which occurred during a skirmish on the goal line in the 57th minute ahead of a U.S. corner kick. A furious Altidore fell to the ground but remained in the game.

The Americans, who started five veterans added for the tournament’s knockout phase, overcame shaky defensive play and poor passing, advancing to a semifinal Saturday night against Costa Rica at Arlington, Texas.

TENNIS

WIMBLEDON: The Tennis Integrity Unit said four matches at Wimbledon and the French Open were flagged for unusual betting patterns.

The TIU’s quarterly report says 53 match alerts were received from April to June out of a total of more than 31,000 pro matches.

Three were at Wimbledon – two in qualifying, one in the main draw – and one was at Roland Garros. Only four were at ATP or WTA tour events.

The TIU said that each alert is assessed but is not, on its own, evidence of match-fixing.

CROATIA OPEN: Top-seeded David Goffin, the 14th-ranked Belgian, marked his return from injury with a 6-4, 6-7 (7), 6-2 victory over 174th-ranked qualifier Attila Balazs of Hungary in the second round.
