The Porters, from Pueblo Country Club and CommonGround Golf Course, respectively, shot a 5-under-par 66 in a modified Chapman format on Saturday to grab a two-stroke lead at the midway point at The River Course at Keystone.

There must be a sense of deja vu for the Porters, who opened with a 64 and led last year en route to a fourth-place finish in this event.

On Saturday, the pair made six birdies and one bogey to set the standard for the 58-team field.

Gary and Alex Kephart of Patty Jewett Golf Course sit in second place at 68 following a five-birdie, two-bogey round. The Kepharts won this title four times from 2005-11.

Guy and Nicklaus Mertz of The Fox Hill Club hold third place after carding four birdies and two bogeys. Guy Mertz finished 41st on Friday in the CoBank Colorado Senior Open at Green Valley Ranch Golf Club in Denver.

Three teams share fourth place at 70, including defending champions Lenny and Nick Nosewicz of Meadow Hills Golf Course. Also at that figure are former CGA president Bill Fowler and son Will of The Club at Rolling Hills, and Russell Roehrkasse of Colorado Springs Country Club and Christopher Roehrkasse of Meridian Golf Club.

In the net division, Bill and Steele Luoma lead the way by six strokes after a 14-under-par 57 on Saturday.

The players will switch to a foursome stroke play format for Sunday’s final round.

For scores from the Parent/Child: GROSS, NET.

Forty-six teams — be they father/son, father/daughter, mother/son, mother/daughter, or grandparent-grandchild — will compete over 36 holes, with a Chapman Scotch format on Saturday and a Foursome Stroke Play (Scotch) on Sunday. There will be gross and net divisions.

Three past champions from the Father/Son are in the field — 2015 winners Jason and Kyler Dunkle, 2014 champs Chris and Steve Dillon, and four-time victors Gary and Alex Kephart, whose last win in the event came in 2011.

Among the other top entrants are Ray and Jimmy Makloski, and Bill and Will Fowler.
