GRANDVIEW - Chalking up 55 victories on the night compared to the 16 first-place finishes notched by the Grandview Neptunes, Sunnyside's summer swim team strode off with a dominating 602-168 decision Thursday evening. The win improved the Sharks' Mid-Valley Summer Swim League record to 8-2. Only the unbeaten Selah Dolphins are ahead of Sunnyside in the league standings. Grandview, its one bright spot last night being boys 14and under competitor Tavian Valenzuela, slipped to 2-8 in the league standings. Valenzuela was one of just two Neptunes in the Grandview pool who earned more than one victory in last night's individual events. He claimed four first-place finishes, those coming in the 40-yard butterfly, breaststroke and freestyle, and in the 160-yard individual medley. In the one boys 14and under race he didn't win, the 40-yard backstroke, Valenzuela was the second fastest from among the 10-swimmer field. The quickest to the finish line turned out to be Sunnyside's Adrian Heffron, who slapped the wall with a clocking of 24.80 seconds, a full 2.38 seconds ahead of the runner-up Valenzuela. The one other Grandview swimmer who recorded a multi-win performance in the individual races was Samanta Castaneda. Competing in the girls 18and under age division, she won the 40-yard freestyle and 160-yard IM events. Castaneda was second to Brittany Broersma of Sunnyside in the three other individual events, and by considerable margins. Broersma elected not to swim in the two races that Castaneda emerged victorious. The Neptunes got their six other individual race wins from Jessa Hellner-Gomez (girls 10and under individual medley), Kaitlyn Ott (girls 12and under breaststroke), Abby Cromwell (girls 14and under breaststroke), Lauren Binfet (girls 14and under freestyle), Nathaniel Gutierrez (boys 12and under butterfly) and from Micah Binfet (boys 16and under breaststroke). On the Sunnyside side of the scoring sheet, 16and under swimmers Katelyn Banks and Alex Perez returned home with the most victories. Banks won four of the five individual events in her age division. In the 40-yard breaststroke she settled for runner-up honors, finishing 1.44 seconds behind teammate Kalie Bestebreur. It was also the breaststroke that kept Perez from making a clean sweep of it in the boys 16and under bracket. Winner of the four other events, Perez was edged out by approximately six-tenths of a second by Grandview's Binfet for top honors in the breast. Besides Broersma at girls 18and under, the Sharks also received three-victory efforts last night from Aydan Harrington and Myles Newhouse. Harrington, at girls 14and under, laid claim to the top spot in the 40-yard 'fly and back, and in the 160-yard IM. Newhouse, swimming in the boys 10and under age division, posted the fastest times in the 40-yard breast and free races, and in the 160-yard IM. The two other boys 10and under races went to Sunnyside teammates Austin Villanueva (butterfly) and Colton Berg (backstroke). Picking up two wins apiece for the Sharks in the individual match-ups were Avery Bonzi at girls 8and under ('fly and breast), Chloe Messmore at girls 12and under ('fly and back), Brielle Newhouse at girls 12and under (free and IM) and Jared Churchill at boys 18and under (back and free). Sunnyside also got one victory apiece in the individual events from 14 other swimmers. Those winners included Chamelle Abringe and Syrina Arevalo at girls 8and under; Ryen Bonzi, Aline Anderson, Bianca Aguilar and Eternity Yanez at girls 10and under; Carter Hauver, Kaiden Frank, Levi Campos and Riley Pasicaran at boys 8and under; and Johnny Heffron, Gabriel Oswalt, Izaiah Gonzalez and Parker Van de Graff at boys 12and under. In the 16 relay competitions staged last night, the Sharks notched wins in 12 of them. Sunnyside is scheduled to host the Prosser Piranhas next Tuesday and take on the Tarpons in the Toppenish pool the following night. Grandview's swim team has a bye next Tuesday before closing out the regular season on Wednesday at Prosser. The league championship meet will start two days later, on Friday, July 26, at the Selah city pool.
