"It was a great day for us today," Chris Zambri said. "In order to be an elite team, you need five guys in the mix every round. We had that today. I would love to see it happen again (Saturday)."

Kang's 67 was built on a six-birdie day, four of which came during a 3-under front nine. He moved to 5-under with birdies on 11 and 13 before a bogey to end the round. He rebounded from his 4-over Thursday and is now tied for 19th at even 142 (75-67).

Anthony Paolucci is tied for third at 6-under 136 (67-69) after his second strong day in a row. He carded his second eagle of the event on the par 5 first hole though still finished the front nine at par. He knocked in four birdies during a 2-under back nine and is tied with three others in third, one back of leaders Julien Brun of TCU and Albin Choi of North Carolina State. Paolucci, now tied with Kang for the team lead in rounds in the 60s with eight, is after his best finish as a Trojan. Going into this week, his previous best was a tie for ninth.

Joining Kang in a tie for 19th at even 142 (72-70) is Steve Lim, who turned in another of his trademark steady rounds. He tallied birdies on 1 and 10 and a bogey on 12 to secure his 1-under round.

Martin Trainer and Sam Smith both made big moves Friday, improving on their 75s Thursday with 68s today to move into a tie for 24th at 1-over 143.
