LAS VEGAS (AP) Andrew Putnam birdied two of the last three holes Friday for a 6-under 65 and a share of the second-round lead with Russell Knox in the Shriners Hospitals for Children Open.
Putnam is played his fourth PGA Tour event. He earned his tour card this year through the Web.com Tour.
Knox, from Scotland, had a 67 to match Putnam at 10-under 132 at TPC Summerlin. Knox had six birdies and two bogeys - on Nos. 2 and 3 - in the second round.
Andrew Svoboda and Tony Finau were a stroke back. Finau shot 65, and Svoboda had a 67.
Defending champion Webb Simpson topped the group at 8 under after a 65.
