Ayrshire, Scotland (My Sportsbook) - Steve Marino, who is still looking for his first PGA Tour win, posted a two-under 68 Friday and owns the clubhouse lead during the second round of the 138th British Open Championship.

Marino lost a playoff earlier this year to Steve Stricker at the Crowne Plaza Invitational at Colonial.

The American had an up and down front nine with three pars, three bogeys and three birdies.

Marino bogeyed the second, but came right back with a birdie on the third. He dropped another stroke on the fourth and followed with birdies on five and six to move to minus-four.

At the par-five seventh, Marino dropped another stroke. His bogey on the 10th was his fourth and final bogey of the day.

Marino posted his fourth birdie of the round on No. 14, where he rolled home a 16-footer. After a pair of pars, Marino poured in a 20-footer for eagle to jump to minus-five. He parred the last to secure the clubhouse lead.

For Marino, this is his first major championship of the season and just the fourth of his career. He has played two U.S. Opens, 2007 and 2008, and missed the cut both times.

In his only other start in a major, the 29-year-old Marino tied for 60th at last year's PGA Championship.
