BENTON HARBOR, Mich. — Colin Montgomerie knows two of the players to watch in a senior major are Bernhard Langer and Tom Watson, so playing alongside them in the first two rounds of the Senior PGA Championship at Harbor Shores worked out well.

Watson shot a 3-under-par 68 on Friday for a share of the lead with fellow Hall of Famers Langer and Montgomerie and three other players.

“Tom had a great finish last week in the Regions Tradition major and Langer is always there, so I felt that if I was equal or around them after two days, I would be quite happy,” Montgomerie said.

Watson, 64, had five birdies and a double bogey — on the par-4 12th — to reach 4-under 138 after two rounds.

“When I don’t do well I get angry with myself still,” he said. “Like (Lee) Trevino said, ‘When I stop getting angry with myself, then I know it’s time to quit.’ And I haven’t reached that point yet. I get frustrated at times, but I still have some fire.”

Langer also had a 68, and Montgomerie shot 69 to join Watson, Bart Bryant, Steen Tinning and Kiyoshi Murota atop the leaderboard. Bryant shot 67, Tinning 66 and Murota 65.

Steve Pate (67) was a stroke back along with Stephen Ames (68), Russ Cochran (69), Mark Brooks (71) and Dan Forsman (73).

Rick Fehr (70) from Redmond was 3 over. Jeff Coston (72) of Blaine missed the cut.

FORT WORTH, Texas — PGA Tour rookie Brice Garnett grew up in a small Missouri town where his home course is a nine-hole layout.

Garnett has gone from Daviess County Country Club and then Missouri Western State to leading at Hogan’s Alley after two rounds at Colonial.

After starting with an eagle, Garnett shot a 4-under 66 and moved to 7-under 133. He had a one-stroke lead over long-putting Chris Stroud (64) and Robert Streb (68).

Adam Scott, playing as No. 1 in the world for the first time, had birdies on three of his last seven holes for a 68 to get to 1 under. He has made the cut in his last 34 PGA Tour events, the longest active streak.

Matt Kuchar, ranked No. 4 in the world, had a chance to move to the top with a win. But he missed the cut by a stroke at 2-over 142.

First-round leader Dustin Johnson (70) dropped into a seven-way tie for fourth at 5 under.

Michael Putnam (71) from University Place and Kyle Stanley (68) from Gig Harbor were both 1 over. Former Huskies Richard H. Lee (75) and Chris Williams (71) missed the cut.

Matthew, 44, had a 5-under 67 to reach 13-under 131 on the Robert Trent Jones Golf Trail’s Crossings Course in Mobile, Ala. Hull, 18, also shot 67.

• Ireland’s Shane Lowry birdied his final two holes for a 2-under 70 and a share of lead with Denmark’s Thomas Bjorn after the second round of the BMW PGA Championship in Virginia Water, England.

Bjorn followed his opening 62 with a 72 in intermittent rain to match Lowery at 10-under 134 on Wentworth’s West Course. England’s Luke Donald (67), the winner of the European Tour’s flagship event in 2011 and 2012, was four strokes back along with Spain’s Rafa Cabrera-Bello (67).

Northern Ireland’s Rory McIlroy was another stroke back along with Swedes Henrik Stenson and Jonas Blixt. They all shot 71.
