Hanzel, 60, of Savannah, Ga., and Royak, 55, of Alpharetta, Ga., might be the best senior team in the field. Hanzel won the 2013 U.S. Senior Amateur, and is a two-time low amateur in the U.S. Senior Open. Royak, the 2007 Atlanta Open champion, is competing in his 11th USGA championship, having advanced to the Round of 16 in last year’s U.S. Senior Amateur. Harvey, 38, of Greensboro, won the 2014 U.S. Mid-Amateur and was the runner-up last fall. He also was a member of the 2015 USA Walker Cup Team. Mitchell, 38, of Bloomington, Ill., was the runner-up in the 2008 U.S. Mid-Amateur. He’s also a former minor-league infielder.

Patrick Christovich and Garrett Rank/John Slayton and Cy Young

Christovich, 38, of New Orleans, and Rank, 29, of Canada, return after advancing to the semifinals last year at Winged Foot. Rank, the 2012 U.S. Mid-Amateur runner-up, just completed his first full season as a National Hockey League referee. He has also won three consecutive Canadian Mid-Amateur titles (2014-16). Christovich advanced to the quarterfinals of the 2014 U.S. Mid-Amateur. They are grouped with Jackson, Tenn., residents John Slayton, 30, and Cy Young, 34, who is not related to the winningest major-league pitcher of all time.

Stewart Hagestad and Sam Smith/Jake Kuwitzky and Scott Roden
Course No. 8, 11:36 a.m., May 27/Course No. 2, 8:12 a.m., May 28

Hagestad, 26, of Newport Beach, Calif., the reigning U.S. Mid-Amateur champion, has joined forces with former University of Southern California teammate Smith, 26, of Turlock, Calif. In April, Hagestad became the first invited Mid-Amateur champion to make the 36-hole cut at the Masters Tournament, earning low-amateur honors. They are grouped with one of the championship’s youngest sides who hail from the Dallas Metroplex. Kuwitzky, 17, of McKinney, just completed his junior year at Spring Creek Academy in Plano, while Roden, 15, of Dallas, is a rising sophomore at Highland Park High.

Erik Hanson and Ben Garrett/Doug Albers and Ryne Fisher
Course No. 2, 9:12 a.m., May 27/Course No. 8, 12:36 p.m., May 28

Since retiring from professional baseball in 1998, Hanson, 51, of Kirkland, Wash., has found golf as a competitive outlet. A right-handed pitcher who played for four major-league teams (Seattle, Cincinnati, Boston and Toronto), Hanson has qualified for three U.S. Mid-Amateurs and represented Washington in four USGA Men’s State Teams. This is his first foray in the Four-Ball, as he partners with Garrett, 34, of Seattle, who won last year’s club championship at Sahalee Country Club, where Hanson is a longtime member. Albers, 38, of Kansas City, Mo., is making his second U.S. Amateur Four-Ball start after missing the cut two years ago with Tyler Shelton. Fisher, 30, of Overland Park, Kan., is competing in his first USGA championship.
