SOUTH BEND, Ind. — The boys from Madison are making it look easy at Notre Dame in the U.S. Senior Open.

For the second straight day, Steve Stricker and Jerry Kelly, friends and competitors since their junior years in Wisconsin, took apart the rain-softened Warren Golf Course, each shooting bogey-free rounds of 6-under 64 in the second round Friday.

Stricker broke the tournament 36-hole record at 14-under 126, a day after shooting an event-record 62 for a share of the first-round lead with defending champion David Toms. Kelly, a playoff winner over Stricker and Retief Goosen last week in the Madison event that Stricker hosts, was two strokes back after their morning rounds.

“I’ve known Jerry from a young age when we were playing amateur events and junior events across Wisconsin,” said the 52-year-old Stricker, the Regions Tradition winner last month for his first major title. “It’s good to see him playing well. I knew this course would set up well for him. He’s doing everything well as it shows from winning last week.”
