HUMBLE, Texas --
The Spaniard's overall score of 12-under 132 matches the 36-hole low at the 7,441-yard Golf Club of Houston, and he's one shot ahead of
Garcia, opening on the back nine, climbed the leaderboard with a birdie-eagle-birdie stretch on his front nine. His eagle on No. 13 came after sticking his 282-yard second shot to within five feet.
"I mean, obviously I feel good, but every week is different," Garcia said. "First of all, we got to finish this week, and hopefully next week I'll be feeling good (and) not too many things will be bothering me health-wise, and then just feel good on the course, hopefully play well and things happen."
After a bogey-free opening round on Thursday, Mickelson -- still recovering from last week's muscle pull that forced his withdrawal from the Texas Open -- overcame a pair of bogeys on Friday with four birdies.
The five-time major winner, who won the Houston Open in 2011, had back-to-back birdies to reach six under and is one of 11 golfers within six shots of Garcia.
Kuchar, who tied for fourth last week in San Antonio, began his afternoon round six shots back of Garcia after opening with a six-under 66 on Thursday.
He reached 12 under with his sixth birdie of the day on the par-four 17th before finding the fairway bunker on the 18th and settling for a bogey to fall back to 11 under.
"If we get some rain and it doesn't blow too hard, of course the course will soften up and the scores will go even lower," Kuchar said. "No telling … It could be really tough."
