But the majority of them, including five that finished their second rounds in the afternoon on Friday, won't be needing their clubs.

With Thursday rain causing a backup on the various starting tees throughout Friday, Round 2 won't be completed until early Saturday. At that point, the top 60 players and ties will move onto the third and fourth rounds.

Those we know that likely won't be moving on?

Grayson Murray, the recent transfer to UNC Greensboro, shot 83-81 and sits in 155th place.

Recent Cal graduate Max Homa, who intends on remaining an amateur through the Walker Cup in September, showed signs of life this morning but couldn't continue the magic. Homa completed his first-round Friday morning with flair. The benefit of plenty of attention from the ESPN cameras, Homa shot 73 and sat tied for 42nd. He holed out a chip for birdie from the first cut on the par-3 17th and stood in good position to make the cut. He struggled to a second-round 78, though, and sits in a tie for 114th at 11-over.

The 19-year-old Gavin Hall shot 4-over 74 in Round 1 but got there thanks to an eagle 2 on the par-4 8th. He struggled to a 7-over 77 in Round 2 and sits tied with Homa at 11-over.

U.S. Amateur champion Steven Fox shot 76-74 and is tied for 104th. He'll need the field to fall back if he hopes to sneak in under the cut line.

Chris Williams, the recent Washington graduate and reigning McCormack winner, shot 75-74 and is tied for 100th. He remains in contention of making the cut should the field fall back.

Cory McElyea of the University of San Francisco, shot 81 in the first round and teed off late in Round 2. He needs a lot of work to get in cut contention.

Cal's Michael Weaver shot his second straight 74 and is in good position to make the cut.

Kevin Phelan of Ireland was the field's low amateur after finishing Round 1 at 1-over 71. He didn't hit a second-round shot until 5:31 and parred his first two holes to stay at 1-over.

Cheng-Tsung Pan overtook him as low amateur early in second-round action, though. Pan shot 2-over 72 in Round 1 and was 2-under through nine holes in Round 2 action. He finished Friday tied for third.

Cal's Michael Kim finished Round 1 at 3-over 73 and was 2-under after 11 holes. He's tied for eighth place after Friday's action.

We'll have updated results and more coverage as second-round play continues and weekend play begins.
