Surrey, England (My Sportsbook) - Paul Casey tallied two eagles, bent a four- iron and shot a five-under 67 Friday en route to the second-round lead of the BMW Championship.

Casey, the seventh-ranked player in the world, finished 36 holes at eight- under 136 and is two shots clear at Wentworth Club, the site of the HSBC World Match Play Championship three years ago.

Defending champion Miguel Angel Jimenez (70), first-round co-leaders David Horsey (71) and Anthony Wall (71), Soren Kjeldsen (69) and Marc Warren (66) are knotted in second place at minus-six.

Casey parred his first hole, but got into red figures after a birdie at the par-three second. He lost that stroke one hole later thanks to a bogey at three, but Casey began his vault up the leaderboard in earnest with an eagle at the par-five fourth.

The Englishman birdied the ninth and 10th to reach seven-under par for the championship. That gave Casey the lead to himself, but he extended with a birdie at the par-five 12th, a hole he eagled on Thursday.

At the par-fourth 13th, Casey found the fairway off the tee. His approach bounced 10 feet in front of the flag, took one more hop, then rolled in for his second eagle of the round.

Casey, now at 10-under par, bogeyed the 14th hole and nearly made a 20-footer for birdie at the 15th. At the 17th, Casey tried to hit a four-iron next to a tree and the winner was the tree.

Casey bent the shaft on his four-iron and made bogey on the hole.

"I've got to try and fix that if I can," Casey said of his shaft. "Could be difficult to find a four-iron shaft. I had to hit a cut three-iron into the last when it was, in fact, a perfect four-iron. I ended up making par instead of knocking it on the green and giving myself an eagle putt.

"The way I finished that round of golf wasn't very good. Having gotten to 10- under after 13 holes, it's certainly disappointing to be sitting in the clubhouse at eight-under. Leading by two, so I have to focus on the positives."

The 2009 season has been full of positives for Casey.

He captured the 2009 Abu Dhabi Golf Championship in January, then lost in the final of the WGC-Accenture Match Play Championship to Geoff Ogilvy five weeks later.

Casey finally broke through with his first win on the PGA Tour the week before the Masters at the Houston Open. But Casey realizes that all of his success this season, and at this venue, doesn't mean anything come the weekend.

"I honestly think it doesn't really matter," acknowledged Casey. "Golf is one of those sports where the ball doesn't care what you did earlier this year or the previous shot."

Former British Open champion Ben Curtis (70), Thomas Aiken (67) and Stephen Dodd (68) share seventh at five-under 139.

Gonzalo Fernandez-Castano, the final first-round leader, struggled to a five- over 77 and fell to even-par 144.

The 36-hole cut fell at two-over 146 and two of this year's biggest winners missed the weekend.

Players Champion Henrik Stenson (148) and Masters winner Angel Cabrera (149) both missed the cut. Retief Goosen and Lee Westwood also failed to make the mark.
