Spain`s Sergio Garcia had five birdies and an eagle en route to a seven-under 65 on Friday to vault into a one-shot lead after the second round of the Houston Open.
Garcia, who matched the low round of the week, completed 36 holes at 12-under-par 132.
"When I look at today, I thought if I am able to shoot three, four under I will be happy," said Garcia, who won the Qatar Masters in January. "To be able to shoot seven-under in those conditions was really, really nice."
Matt Kuchar bogeyed his final hole at the USD 6.2 million (4.5 million euros) US PGA Tour event to close out a five-under 67 and finish a shot off the pace at 11-under 133.
Windy conditions made scoring difficult on Friday and bad weather was expected to roll in late in the day on Saturday at the Tournament Course at the Golf Club of Houston.
Players will tee off in threesomes from the first and 10th holes to try and get as many into the clubhouse as possible before the storms hit.
Three-time 2014 winner Jimmy Walker (65), Australian Matt Jones (68), Cameron Tringale (68) and Shawn Stefani (69) shared third place at eight-under. Steve Stricker (69) and Ben Curtis (70) were tied for seventh at seven-under.
Jones will play in the final threesome Saturday with Kuchar and Garcia, who eagled the par-five 13th hole after hitting his 284-yard approach shot to five feet.
Garcia, who started his round on the 10th, sandwiched his eagle between birdies on the 12 and 14 on his first nine.
He added three consecutive birdies on holes three, four and five coming in.
Garcia hit 13 of 18 greens and missed just one fairway in his round.
Garcia has finished no worse than 16th in five US PGA Tour starts this season and placed in the top 20 in his past 12 worldwide starts.
"I do feel like I`m playing nicely," Garcia said. "I feel very comfortable with my equipment. I feel comfortable with myself in and outside the golf course."
Garcia said he is not reading too much into his strong start this week as he plays his final tune-up before the Masters.
