Keegan Bradley and Miguel Angel Jimenez went nose to nose with each other after a disagreement over a ruling on the par 5 18th at the WGC - Cadillac Match Play. The disagreement spilled over into Jimenez saying something to Bradley's caddy which then saw the American square up to Jimenez. The two tried to patch things up at the end of the round but it didn't really happen.
Our money would be on Miguel.
