"It was a challenge out there today," Stricker said. "It was gusty, the wind came out of the south -- where we played yesterday, it was out of the north, so it was a totally different golf course."
Jobe made an 18-foot birdie putt on the par-4 18th, and Stricker missed a 6-footer to leave them tied.
"It's pretty straightforward off the tee, and the greens are what make it difficult at times and you've just got to be in the right spot to have good birdie putts at it," Stricker said. "If not, then you've got to play pretty defensive at times. ... It's a simple game plan, but try to stay out of trouble and keep trying to put pressure on everybody."
Stricker won in Arizona and Mississippi in consecutive starts in May for his first senior victories. Next week in France, he will be one of U.S. Ryder Cup captain Jim Furyk's assistants.
Jobe birdied four of the last five holes. He won last year in Iowa for his lone senior title.
"I think we kind of got used to what the wind was," Jobe said. "Of course, there's some scoring holes on the back. The front played very difficult. It was just kind of 'try not to screw up' for a while there."
Smith was a stroke back after a 68.
McKenzie had a 77 to drop into a tie for 43rd at even par.
