MCKINNEY, Texas -- Virginia posted the best single-round score in the program's history to take the opening-day lead at the Jim West Intercollegiate at TPC Craig Ranch. The Cavaliers finished the first two rounds of play at 36-under 540. Iowa State trails UVa by 13 shots at 553.

UVa shot 15-under 273 during the morning round and followed that up with a school-record 21-under 267 during the second round. The program's previous best single-round team score was 19-under 269 at the John Burns Intercollegiate at the Turtle Bay Resort in Kahuku, Hawaii, during the 2011 season.

Bard had 12 birdies and just one bogey during his two rounds.

All-American Denny McCarthy posted UVa's best single-round score, shooting 8-under 64 to better his previous best single-round effort by one shot and come within a stroke of tying the UVa 18-hole scoring mark.
