Johnson, McGirt on top at John Deere

Zach Johnson and William McGirt were at 12-under-par 130 and tied for the lead at the halfway point of the John Deere Classic.

They were a stroke ahead of Steven Bowditch, Johnson Wagner and Brian Harman.

Three-time Deere winner Steve Stricker shot a 65 Friday for a 133 total to vault into contention at the par-71 TPC Deere Run, and was tied for sixth with Rory Sabbatini, Ryan Moore and Todd Hamilton.

Johnson, the Deere winner in 2012, shot a 4-under 67 in the afternoon despite two bogeys in his last four holes. That dropped him into a tie with McGirt.

McGirt, 35, is looking for his first PGA Tour victory.

He added a 66 to his opening 64, but like Johnson, he finished with a bogey. McGirt's best finish this year is a tie for sixth in the Northern Trust Open at Riviera. Since then, he's had one top 10 and has missed the cut in seven of 14 tournaments.

McGirt is winless on the PGA Tour in 111 starts, most of them in the last four years. His best finishes are a pair of ties for second in the Canadian Open, in 2012 and 2013.

Martin takes 3-shot lead at Women's British Open

American Mo Martin had a plan to play Royal Birkdale. It has worked better than she imagined at the Ricoh Women's British Open.

Martin took two putts from short of the green on the par-5 18th for her 10th birdie in two days. It gave her another 3-under 69 and a three-shot lead over Beatriz Recari of Spain and former U.S. Women's Open champion So Yeon Ryu going into the weekend.

The weekend will not include Michelle Wie.

Coming off her first major in the U.S. Women's Open at Pinehurst No. 2, the 24-year-old from Hawaii never got anything going and fell apart over the closing stretch for a 78 to miss the cut by three shots.

Only nine players remained under par and wind has yet to get fierce.

Montgomerie leading at Senior Open

Colin Montgomerie shot an even-par 71 on Friday on the second day of the U.S. Senior Open and leads Scott Dunlap by one stroke.

Montgomerie opened with a 65 on Thursday. Dunlap had a 69 in the first round and a 68 in the second to get to 5 under for the tournament.

Dunlap was at 2 under after starting on the back nine, and then went back to the front nine and birdied Nos. 2, 5 and 7 on his way to a 32.
