One of coach Selwyn Jones’ big worries at the start of last season was replacing departing quarterback Ryan Jones. Former Misawa Jets signal-caller Darone Frierson has proven to be more than up to the challenge.Frierson threw three touchdown passes and ran for a score and Yokota’s defense returned two fumbles for TDs and covered another fumble in the end zone as the Warriors, the last U.S. Forces Japan-American Football League team to play its first game, routed Yokosuka 53-0 Saturday.“I was concerned” heading into the game, Jones said, because the Warriors had no practice in the week leading up to it, thanks to military commitments.Frierson eased those concerns, hitting Rob Harris for touchdown passes of 20 and 10 yards and also a 20-yarder to Michael Garcia that capped the scoring.“He was a little rusty, he misfired on a few, but once he found his way, he started finding people,” Jones said, adding that Frierson got some help from Yokota’s “running back by committee.”That group also produced a touchdown, in the form of diminutive running back Anthony “Ant” McNeill, Yokota High School’s career rushing leader. He got the Seahawks on the board with a 15-yard first-quarter TD run.Defensively, Quortez Dorsey fell on a Seahawks fumble in the end zone, and Mark Rocamontes returned a fumble 1 yard and Joe Stevens another for 40 yards for Warriors touchdowns.“We have a lot of work to do” to get ready for the Warriors’ next five games, Jones said. “It was a very good start.”The Seahawks, meanwhile, fell to 0-3 to start the season. The margin of defeat was the worst for a Yokosuka team since losing 64-0 to Yokota in 1998. “Good game by Yokota,” Seahawks coach James Price said.
