Senior guard Dominik King donated seven points, nine boards and two blocks for the Patriots (8-2), who vaulted to the top of the East Division standings in their first divisional game.
"We just talk about figuring out a way to win and grind it out,'' said GW coach Rick Greene. "I wasn't happy how we played, but I thought we just kept going. Jon got hot and some other kids made some plays and I thought we got on the boards a little bit better late.''
Riverside proved tough to shake, vaulting out to a 7-0 lead in the first couple of minutes behind five straight points from senior forward Tyus Wood. Then when GW gave itself some breathing room late in the second quarter, Brock tied it up at 23-all on a steal and layup and free throw with 1:16 remaining before the break.
Wood tallied 16 points, but only five after the opening quarter, and chipped in six rebounds for the Warriors (4-4, 0-2). Brock dropped in 10 points, six boards and five assists.
"I'm proud of my kids,'' said Riverside first-year coach Ryan Carter, whose team shot 27.8 percent. "They did all they could.
"We're getting killed on the glass right now. We're not getting enough shots in practice and games. We're just cold. Getting in the gym for practice will help us a whole lot.''
GW seems to be rounding into form as the calendar ticks down. The Patriots were eighth in the Class AAA Associated Press preseason poll before dropping out. GW was the top vote-getter this week outside teams in the top 10.
"Each game new guys are stepping up, which is what we need,'' Elmore said. "We need to find a certain lineup that everybody meshes together in. That's really what we're starting to do is get better and better.''
