Former major winners Keegan Bradley, Jimmy Walker, Jason Dufner, Lucas Glover are also in the field.

3M Open executive director Hollis Cavner on Friday offered his final two sponsor's exemption to Mexico's Alvaro Ortiz and former USC golfer Justin Suh, one of four college stars who just turned pro now added to the field.

Several players among Friday's leaders at the new Rocket Mortgage Classic in Detroit are headed to Minnesota next week. Included: Nate Lashley, Cameron Champ, Charles Howell III, Ryan Armour, Joaquin Niemann, Peter Malnati, Rory Sabbatini and Hideki Matsuyama.

The field's final four players will be added at a Monday qualifier at Victory Links in Blaine.
