Bettingzone headline selection Phil Mickelson is the new favourite for the US Masters at the halfway stage.
Lefty made his move on the back nine in the second round at Augusta to finish on three-under-par, three shots behind leader Justin Rose.
Having started the tournament as an 8/1 chance he's now as short as 7/2 with Skybet to win a first Major - though Bet Direct and Sporting Odds both offer 9/2 and he's 5/1 (6.0) on Betfair.
Most of the big names are bang in contention and it's made for a wide-open betting heat.
World number one Tiger Woods is right back in the mix after a second round 69 put him on level par and having traded at as big as 26 on Betfair he's now the second favourite on the leading exchange at 8.2, just ahead of Ernie Els (two-under) at 8.4 and Rose on 9.0.
It's a similarly close call with the traditional fixed odds firms with all three players a top-priced 7/1 - Bet Direct quoting that price about Woods and Els while SuperOdds offer those odds on Rose.
And after holding his nerve well in round two, Rose is confident of a big weekend.
He said: "I did my best to stay in my own game and that meant not looking at the leaderboards. I dealt with being in the lead and I think that's a big advantage going into the weekend."
Davis Love III (two-under and 9/1 with Sporting Odds), Jose Maria Olazabal (four-under and 10/1 at Ladbrokes) and Alex Cejka (four-under and 18/1 with Bet Direct) are the other players quoted at less than 20/1.
