We narrowed down 64 of the hottest shirtless  studs of the year, and now it's up to you guys to pick the 32 who will make it into the second round of our Summer Shirtless  Bracket. These matches close tomorrow , and a few guys really need your votes! Here's a rundown on some of the men who need a few last minute rallies :
- Zac Efron  vs. Jerry O'Connell : Jerry has a few years on Zac, but it's Zac who's apparently running away with this matchup — it's a relatively close one, but the High School Musical  star is still winning by a fair margin. Matt Damon  vs. Justin Chambers: The Grey's Anatomy  star has the slimmest lead over the leading man from the Bourne Identity  — Justin is beating Matt by only 175 votes.
- Channing Tatum  vs. Justin Timberlake : It's also a close one between Channing and Justin — they both have killer dance moves, but it look like JT might lose in this faceoff.
The round will close tomorrow at midnight — make sure to fill out your ballots  before then!
