Here's a look at the Bobby Jones bracket going into Thursday's second round of the World Golf Championships-Accenture Match Play Championship. OTHER BRACKETS: Ben Hogan | Gary Player | Sam Snead | Second-round predictions

MOST INTRIGUING MATCH: Hunter Mahan vs. Rory McIlroy. This is an interesting match between two young guns. That said, Mahan will be the old man in this duel at 26 years old, seven years older than the young Irishman McIlroy. Look for it to be a hard-fought battle. Mahan's experience with the Presidents Cup and the Ryder Cup in each of the last two years might prove to be the difference. Then again, McIlroy is riding high on confidence after his first win on the European Tour a few weeks back in Dubai.
MOST COMPETITIVE MATCH: Camilo Villegas vs. Miguel Angel Jimenez. This will be a battle between one of golf's flashiest players and one of golf's most laid back players. They're also two of the most fun players the game has to offer -- Villegas with his Spiderman way of lining up putts and Jimenez with his constant puff of a cigar with the long, red ponytail hanging out of the back of his hat. Villegas will bring the power, but Jimenez will bring the ability to grind.
POTENTIAL BLOWOUT WARNING: Tiger Woods vs. Tim Clark. These two faced each other in the second round during the 2007 World Golf Championships-Accenture Match Play Championship and it was ugly for Clark, as he experienced the short end of a 5 and 4 Woods romp. After seeing Woods on Tuesday with no sign of knee trouble, that same outcome could very well happen again. Not to mention, this is Clark's sixth appearance in this event and just the second time he's made it through the first round.
POTENTIAL THIRD-ROUND MATCH: Tiger Woods vs. Hunter Mahan. This would be quite the compelling match up. Mahan is one of the young guys who shined in Tiger's absence. Despite not picking up a win, Mahan played a part in helping the U.S. team win the Ryder Cup. Plus, Mahan doesn't come off as a guy who's easily intimidated. Could make for an interesting match.
