Kuchar earns Phoenix Open lead

Updated: 

American Matt Kuchar was flawless as he took charge after the opening round of the Phoenix Open.

A lot of eyes are on Dubai this week to watch Tiger Woods' second attempt at a comeback, but the PGA Tour is partying in Arizona thanks to Kuchar and Co.

With the stadium atmosphere in place on the famed par-three 16th hole, the Phoenix Open has become golf's most entertaining event of the season, and Kuchar jumped out to a one-stroke lead on Thursday.

Kuchar carded a bogey-free seven-under-par 64 in Scottsdale.

The seven-time PGA Tour champion played his last six holes in four under after birdieing his first two holes of the day.

Red-hot Hideki Matsuyama, who has four wins and two runner-up finishes in his last eight starts and is defending his title this week, posted a blemish-free 65.

Brendan Steele also shot a six under after starting out seven under through his first 10 holes.

Chris Kirk is among five players tied at five under.

Big names such as Rickie Fowler, Brooks Koepka, Steve Stricker and J.B. Holmes had 67s.

Phil Mickelson got off to a hot start, but he stalled in a three-under 68.

Justin Thomas, who has already won three times this season and shot a 59, finished with a 69 after a rocky start. He rebounded with birdies on three of his last six holes.
