The 31-year-old Lamb, who played college golf at Tennessee and hails from South Bend, Ind., made an eagle and six birdies in an 8-under round of 63 to tie with Australia’s Daniel Gale atop the leaderboard. Also earning their spots in the field at TPC Twin Cities this week are Chris Naegel and Andre Metzger, who advanced in a 4-for-2 playoff. Lamb has Monday qualified for his two previous starts this season, finishing T-15 in the Corales Puntacana Championship and T-30 in the Honda Classic, after advancing in a 16-for-1 playoff that ended on Tuesday morning for the final position in the field. Last season, Lamb made 15 cuts in 31 starts on the Korn Ferry Tour during the wrap-around season and was 129th on the regular-season standings. He was a PGA Tour member in 2017 and 2018, with a best finish of T-3 at the 2017 John Deere Classic, where he shot 63 in the third round and finished two strokes back of winner Bryson DeChambeau.
