Maggert’s bogey-free round of 9-under 62 moved him from 39th place after the first round to a tie for second. He birdied half the holes at TPC Deere Run, including five of his last nine.
Harman had a second straight 65, the last two of his seven birdies coming after a 48-minute thunderstorm delay.
Matteson bogeyed the par-4 18th after getting four birdies in the first 17 holes to finish at 13-under 129.
Maggert one-putted 10 greens and saved par twice en route to matching his career-low round. He finished by making a 13-foot birdie putt on the par-4 ninth hole.
“I saw the putts better today,” Maggert said. “But I’m going to be aggressive tomorrow. I feel I need another really low round Saturday or Sunday, 7 or 8 under, to be in contention. The last few years, guys have really been lighting it up here.”
Including Maggert’s 62 and Matteson’s first-round 61, there have been eight rounds of 62 or lower at Deere Run in the past five years. The best effort was Paul Goydos’ Tour-record-tying 59 two years ago.
BOSSIO FALLS IN PNW MEN’S AMATEUR
Olympia’s Jarred Bossio lost his quarterfinal match at the Pacific Northwest Men’s Amateur Championship, 4 and 3, to Shotaro Ban of San Jose, Calif., in Walla Walla.
Bossio, a Capital High School graduate, did not win a hole until No. 12. He also won No. 13, cutting Ban’s 5-up lead to 3 up. Ban clinched the match on the par-4 15th hole, however, when he made par and Bossio made a bogey.
Ban will face Bainbridge Island’s Carl Jonson in the 36-hole final today.
CADDY LEADS SENIOR
Lance Ten Broeck chooses to carry a bag rather than swing a club for a living to make more money.
If Ten Broeck can keep his lead at the U.S. Senior Open in Lake Orion, Mich., for two more days, though, he will more than double his highest annual income on a golf course.
The full-time caddie for Tim Herron and part-time player shot a 68, putting him at 6-under 134 and one-shot ahead of first-round leader Tom Kite.
Ten Broeck has a chance to make about $500,000 on Sunday after earning less than half that total in his best year as a caddie.
Phil Mickelson broke out of his slump with an 8-under 64 at the Scottish Open in Inverness, leaving him five shots off the second-round lead shared by Alexander Noren and Francesco Molinari.
Noren’s second straight round of 6-under 66 moved him to 12 under alongside Molinari, who managed a 2-under 70.
