CHESTERFIELD, N.J. — Kevin Murphy charged onto the golf scene as a freshman at Rogue River High this past school year, and he doesn't appear ready to slow down.

The 16-year-old, who finished second in the Class 3A/2A/1A boys state tournament, continued his fine play Tuesday in the opening round of the 42nd Trusted Choice Big I National Championships.

Murphy shot a 4-over-par 75 and is tied for 21st place after 18 holes of the major junior event. The four-day, 72-hole tournament is being played at the 6,743-yard Old York Country Club.

Murphy teed off in one of the last groups, starting on the first hole. As such, he'll be in one of the first boys groups out this morning, starting at No. 10.

There are 102 boys in the field and 54 in the girls division. The tournament is for ages 13 to 18.

Murphy sprinkled a bogey on the first hole and a double bogey on the fifth with seven pars to finished the front nine at 3-over 38. But he birdied the 10th and 12th holes on the second nine to keep his score under control.

Murphy made the tournament through local qualifying at Rogue Valley Country Club in June, then via state qualifying 21/2 weeks ago at Trysting Tree Golf Club in Corvallis.

Only two boys and two girls from Oregon advanced.

Baseball

S.O. RIVERDAWGS 12-2, NEVADA BIGHORNS 4-0 — Frank Charlton shut down Nevada through seven innings and Todd Sorenson picked up where the former Eagle Point standout left off to help Southern Oregon complete a doubleheader sweep and clinch the WCL Tri-State's fourth and final playoff spot.

Charlton struck out 11 and allowed only one walk and three hits in seven shutout innings, while Sorenson picked up his first save for the RiverDawgs (16-19 8-15 WCL Tri-State) after allowing two hits in two scoreless innings.

Nick Rodda hit a one-out double in the first inning and scored on a two-out single by Ryan Hayden to open the scoring. In the sixth, Johnny Omahen hit a leadoff single and eventually scored on a throwing error by Nevada shortstop Eric Maupin.

The Bighorns (9-25, 3-17) greeted Sorenson with a single by Ryan Trosko and a double by Maupin, but the reliever settled in to get three straight outs to squash the threat.

Omahen finished 2-for-3 for the Dawgs, who entered the three-game series needing to win at least one game to edge the Bighorns for a playoff berth.

In the opener, Omahen's two-run double capped a four-run fifth inning to put the Dawgs up 7-3 and give Jon Flinn more than enough cushion for his third win.

Chris Bradshaw was 3-for-4 with two runs and two RBIs, Jonah Northrop was 2-for-5 with two runs, Steven Candelaria 2-for-3 with one run and two RBIs and Jack Graham 2-for-4 with one run and two RBIs to pace Southern Oregon.

The RiverDawgs wrap up their regular season at 7 tonight in the final game of the series with Nevada. It will be Fan Appreciation Night at Harry & David Field.
