Nearly 90% of bettors are backing Phil Mickelson and Tom Brady on Tuesday night.
Brady and Mickelson are playing Bryson DeChambeau and Aaron Rodgers in The Match IV at The Reserve at Moonlight Basin golf course in Big Sky, Montana.
The 18-hole match play event (5 p.m. ET, TNT, TBS, TruTV) is a modified alternate-shot format. That means the players alternate shots after tee shots. The money raised from the event will go to three charities across the country.
Mickelson and Brady are backed by a lot of bettors at BetMGM because they enter the match as underdogs.
