Tom Loveless of Argyle whipped his former Good Counsel High School teammate, Gary Marlowe of Woodmont, 5 and 4, at Redgate yesterday for the Montgomery County Sentinel Junior Golf Championship.

In the semifinals yesterday, Loveless eliminated Dan Bosis of Indian Spring, 3 and 2, and Marlowe and turned back John Miller of Manor on the 20th hole.

Marlowe, 18, played No. 1 on the Good Counsel golf team this year and Loveless, 16, was No. 3. Marlowe will enroll at Louisana State University this fall. Loveless will be a high school senior.

"I never saw anybody improve as much as Loveless in the last three months," said Marlowe. "I lost to him in the District Amateur last week, but I wasn't convinced because he chipped in to beat me on the 19th hole. This time, he did a good job on me."

The slender Marlowe may have lost his steam in the morning match with Miller. Marlowe was three up at the turn and two up after 16, whereupon Miller won the last two holes of regulation. Marlowe won the match when he hit a seven-iron shot six inches from the cup on the 20th hole.

Bosis, 16, was four down at the turn to Loveless. The closest Bosis got was when he birdied the 15th. The 16th was halved to end the match.

Loveless was five up on Marlowe after nine holes. He won the 10th with a par but lost the 11th to Marlowe's par. The 12th was halved. Marlowe cut the margin to four when he birdied the 13th, but Loveless chipped to within inches of the pin for a birdie on the 14th to ice it.

In the 16-17 first flight, Vern Caswell of Brooke Manor defeated Wade Heintzelman of Washingtonian, 5 and 4. Webb Heintzelman won the 14-15 championship by defeating Richard Parkinson of Argyle, 5 and 4.

Blaine Coblentz captured the 12-13 flight with a 2 and 1 victory over Brian Mahon.
