Kuchar stands at 15 under overall heading into Sunday's final round, four shots ahead of second-round leader Garcia and Cameron Tringale. The three will be paired together on Sunday.
"It's a nice position to have played well last week, to have been in the last group with a chance to win and again to come back this week, completely different course, and have another shot to win," Kuchar said.
Kuchar's last win came at the Memorial last year, and he has eight top 10 finishes this season in 10 events.
He'll have the opportunity add to that resume on Sunday, weather permitting, as well as fuel his surging confidence leading into next week's Masters, where he finished in a tie for eighth last year.
The prospect of a winner's share of nearly $1.2-million, however, has Kuchar locked in on this weekend first even with the prospect of competing for his first major championship looming next week.
"I've been playing some steady golf for a couple of years now and feel like my chances of playing well tomorrow are pretty good," Kuchar said. "Having a four-shot lead is a great position to be in."
The golfers went off both tees in threesomes early Saturday morning in anticipation of severe weather in the evening, a format they'll use again Sunday with hopes of avoiding a Monday finish leading into next week's visit to Augusta National.
In Rancho Mirage, Calif., Michelle Wie and Lexi Thompson topped the Kraft Nabisco leaderboard, setting up a possible final-round showdown the LPGA Tour has been waiting for.
The 24-year-old Wie shot a bogey-free 4-under 68 on Saturday to match Thomson at 10-under 206 at Mission Hills in the first major championship of the year.
The 19-year-old Thompson settled for a 69 after driving into a fairway bunker and missing a 3-foot par putt on the par-5 18th. She also missed two short birdie putts.
