Three rounds are now in the books at the 3M Open as the PGA Tour gets closer to both the Olympics and the FedEx Cup Playoffs over the next month. Though the 3M Open is in a spot on the schedule sandwiched between the Open Championship and Tokyo Olympics, it attracted a good field that includes major champions Dustin Johnson, Patrick Reed, Louis Oosthuizen, Bubba Watson and Sergio Garcia.

With 54 holes completed, none of those big names are in the hunt for the win, but we still should be in for an exciting finish nonetheless. After three rounds, Cameron Tringale sits atop the leaderboard at TPC Twin Cities at 12 under. He has a tall task ahead of him on Sunday if he wants to hang on for the win, though, as a host of golfers are on the chase including Gary Woodland and Maverick McNealy sitting one shot back. 

This finish, again, should be a good one as we're all still trying to come down off the high of last week's Open at Royal St. George's. 

Here's how you can watch the final round on Sunday as Tringale looks to hang on for the victory.
