Chris Kirk, Philip Knowles and Andrew Putnam share the lead after two rounds of the Rocket Classic, while the course record fell for the second straight day Friday at Detroit Golf Club. Kirk posted a 65 Friday, Knowles a 64 and Putnam a 66. They sit at 14-under-par 130 halfway through the tournament, one shot clear of Jackson Suber (65). Aldrich Potgieter of South Africa (70) and Mark Hubbard (69) are tied for fifth at 12 under. Meanwhile, Jake Knapp shot 123 spots up the leaderboard by following an even-par 72 with an 11-under 61. One day after Potgieter and Kevin Roy posted rounds of 62 to break the course record, Knapp took it for himself by making nine birdies and one eagle in a bogey-free round. Knapp is one of 14 players tied at 11 under, a logjam that also includes Roy (71), Ben Griffin (67), Gary Woodland (66) and Hideki Matsuyama (66). Scoring conditions in Detroit were so favorable for the first two days that the projected cut as of 5:30 p.m. was 6 under par. Wyndham Clark (4 under), Max Homa (3 under), South Korea's Tom Kim (1 under), defending champion Cam Davis of Australia (even par) and 2023 champ Rickie Fowler (1 under, two holes to play) were all on the wrong side of the cut line.
