DES MOINES - The Bobcats heated up late Monday, though it wasn't enough to tame the Dragons' fire throughout the evening.
Johnston built off an early lead to fend off the Marshalltown boys' bowling team 3,147-3,027 at Plaza Lanes.
Johnston took a 2,016-1,953 advantage after the first two games, before outscoring the Bobcats 1,131-1,074 in the Baker games.
Floyd Speck led Marshalltown with a 428 series, rolling a 214 in both games. Brett Wax tallied a 396, Grant Whitmore added a 378 and Dacoda Ewalt fired 377.
"The shot was a little more challenging and we got off to a slow start," MHS coach Jeremiah McKeever said. "The boys fired it up to start Bakers, but it was no match for Johnston's 226 average in Bakers."
Aaron Schwandt had a 374 for the Bobcats and Kyle Bartles tallied a 345 series.
Anthony Denny paced the Dragons with a 491 series, while Cody Erickson (427) and Jared Erickson (403) also broke 400.
"Johnston bowled nearly 200 pins over their match score average and 30 pins over their Baker score average," McKeever said.
MHS girls ousted, too
The Bobcat girls were firing on all cylinders, but it wasn't enough to stop the Dragons in a 2,592-2,155 setback.
Tia Vergauwen propelled a career night for Marshalltown with a personal best series of 381.
Kelli Bormann led Johnston with a 384 series and Katy Richardson had a 366 as the Dragons led 1,681-1,521 heading into the Baker games.
"I was impressed with how the girls bowled tonight," McKeever said.
"Five of the six girls bowled over their average."
Kathleen Ferrin rolled a 323 series and Mercedies Bills shot a 302, while Samantha Tocheri (268), Lily Neuan (247) and Lindsay Wiegand (241) also chipped in.
"Mercedies also set a personal best high game with 187," McKeever said. "They were really working as a team and having fun."
The Bobcats entertain Mason City in a makeup dual today at the Totem Bowl at 3:30 p.m., before hosting a Class 2A substate tournament Thursday at noon. Other teams in the field include Southeast Polk, Ankeny, Urbandale and Mason City.
