SAN DIEGO — Grand Canyon men's soccer was not done making history Thursday.

The first team in program history to win an NCAA Division I Tournament match notched its second NCAA Tournament victory in four days, upsetting national No. 9 seed San Diego 2-1 on its home field Sunday night for a trip to the Sweet 16.

San Diego (13-3-3) had not lost in 10 home matches this season, but GCU (14-3-5) struck early with a goal from graduate forward Ben Assane in the seventh minute and won the match on freshman Junior Diouf's nation-leading 18th goal in the 88th minute.

Despite the Toreros' 15-6 shot advantage, the Lopes made its shots count to advance to the Sweet 16 for a matchup with tonight's Portland-Denver winner on Saturday or next Sunday.

After San Diego tied the match in the 66th minute, the match was nearly headed to GCU's second consecutive overtime match after winning Thursday at UCLA on penalty kicks.

But in the 88th minute, GCU graduate goalkeeper Daniel Ibarra booted the ball toward midfield, where late-match substitution Allan Rosales, a junior midfield, controlled the ball and passed wide to junior defender Felipe Cobian. With Diouf streaking ahead, Cobian sent a pass upfield and a San Diego defender fell down as Diouf took control outside the box, dribbled into it and chipped a goal from 16 yards out past the charging Toreros goalkeeper.

Ibarra made his sixth save in the 89th minute to help seal the Lopes' second NCAA Division I Tournament victory in four nights, with both coming in southern California.
