Former amateur star Gary Mankulish and veteran pro Tom Smack shot five-under-par 67s over the short Allview Golf Club course today and tied for the first-round lead in the Middle Atlantic Open.

A shot back was Roger Simpkins, former University of Maryland player now an assistant pro at Indian Spring, with Henry Seymour of the Northern Virginia Golf Center the low scorer for the day at the 7,210-yard Hobbit's Glen course, with a three-under 69.

A field of more than 300 has entered this 54-hole tournament, with play split the first two days between Allview and Hobbit's. Hobbit's figures to play three or four shots tougher than Allview.

The final 18 will be played Wednesday at Hobbit's, where defending champion Paul Ryan limped in with an 80 today.

In the simultaneous two-man team championship, pairing a pro and an amatuer, Fred Gibson and Dave Rasley of Germantown shot 64 and tied Glen Miller and Tony DeLuca of Chantilly for first place. All play today was at Allview, in a better-ball format. The team entrants play Tuesday at Hobbit's with each partner's round added to today's total.

Mankulish, who won the Maryland Amateur twice, along with the District and Middle Atlantic Amateur, and now is an assistant pro at Woodmont, did some fine chipping today, leaving five of his six successful birdie putts from six feet or less for birdies.

He birdied the first hole from six feet, the second from three feet and the ninth from two feet.

On the back he chipped to within three feet for a bird on the 12th, sank a 20-footer for another birdie on the 15th and made a four-foot putt on the par-5 17th for his sixth and last birdie.

Smack, from the Pine Shore Golf Club on Maryland's Eastern Shore, said he had a bad headache when he fashioned an even par 36 on the front nine at Allview. But he found something better than aspirin on the back nine. He had seven birdies on his last 10 holes, touring the back nine in 31.

He had nine birdies in all and took only 24 putts, with 12 one-putt greens, because of phenoimenal sand wedge play that enabled him to get up and down on four occasions off the green. Eight of his birdies came on putts of six feet or less.
