Springer holed out from 55 yards for eagle on the par-5 17th and then made a 12-foot, 8-inch birdie putt at the last to shoot 12-under 59 at TPC Deere Run.
“I’m feeling good. Kind of, I don’t know, at loss for words in terms of being able to do that,” Springer, who had never shot lower than 61, even in practice, said after his round. “I feel like that’s one the rare things in golf, so to kind of have that opportunity and pull it off, it feels pretty special.”
It’s the second 59 in three weeks on Tour as Cameron Young shot that number in the third round of the Travelers Championship. It’s also the second 59 in tournament history, with Paul Goydos first doing so in 2010.
Neither Young (T-9) nor Goydos (runner-up) went on to win their respective events. Springer leads by two shots over fellow Tour rookie Sami Valimaki (61).
