OMAHA, Neb. (AP) — Kenny Perry shot a 3-under 67 on Thursday and is tied for the lead at the U.S. Senior Open, putting together a solid start in his bid for a second straight win in a senior major. Perry, who won the Senior Players Championship two weeks ago at Fox Chapel, Pa., made five birdies against two bogeys at Omaha Country Club. And he’s got plenty of company atop a crowded leaderboard. Michael Allen and Jay Don Blake also shot a 67 on Thursday morning, and Gary Hallberg, Mark O’Meara, Tom Lehman and Fred Funk posted the same score in the afternoon. There had never been as many as seven co-leaders after the first round at a U.S. Senior Open. The previous record was five in 1997.
