First-round leader Bob Bilbo of Good Counsel completed a troublesome second round with a quadruple bogey 8 and left the 57th Frank Emmet Schoolboy golf championship up for grabs heading into today's final round at Westwood Country Club in Vienna.

Evan Selig of St. Albans found himself atop the leaderboard after Bilbo's misfortunes. Selig added 76 to an opening-round 79 and leads with a 36-hole total of 155 in the 54-hole tournament, being contested for the first time at stroke play instead of head-to-head match play.

Jim Cangiano of Poolesville (79 yesterday), Mike Benner of Laurel (78) and Chris Cazalas of South Lakes (79) all were one stroke behind Selig at 156, followed by Bilbo at 84-157.

Bilbo, who owned a four-shot lead after opening with 73, hit into woods and water on the final hole and then four-putted the green for an 8, and completed his final nine holes in 45 strokes.

"I played lousy," said a disconsolate Bilbo, son of the Argyle Country Club head professional of the same name. At 15, Bilbo is trying to become the youngest Emmet Schoolboy winner. He shot a good round on Monday's opening day at Army Navy in Arlington but the tournament switched to Vienna for its final two rounds and Bilbo struggled mightily, as Westwood played long and difficult from the back tees.

Selig, 18, a recent graduate of St. Albans, prospered. "I hit the ball very well with the irons," he said. "I made some five- and six-foot putts to keep myself in it." Selig will attend Colgate University this fall.

Tournament Director Bob Riley said the difficulty in obtaining courses led to the decision to depart from traditional match play, which required two rounds each day.

"The extreme growth of golf in the area has caused heavy demand on the courses," said Riley, "which makes it very hard to be able to play two rounds a day, which is required in match play."

"I'm not so sure which one suits me better," said Selig. "But the way I'm hitting it now, I feel pretty comfortable at stroke play."

Other golfers in contention: George Bradford of Wilde Lake at 81-158, followed by three at 160, Peter Vartabedian of Bowie (82), Greg Demkin of Herndon (80), and Darin Snoots of Brentsville (78).

The tournament started with 96 golfers and was reduced to 25 for yesterday's play. Twelve golfers remain for this morning's final round, starting at 8.
