OAKLAND -- The Bishop O'Dowd High baseball team didn't waste any time putting runs on the scoreboard Thursday in its West Alameda County Conference-Foothill Division game against visiting Arroyo.

Bishop O'Dowd took a four-run lead in the first inning and scored two more in the second on its way to a 9-2 victory over the Dons. Coupled with Castro Valley's 3-0 loss to Berkeley, the Dragons clinched the outright WACC-Foothill regular season title.

"That set the tempo ... to put that four-spot on them," said Bishop O'Dowd's Channing Nesbitt, who had an RBI single in that first inning. "We had lost to them earlier this week, so we knew we would have to be more focused."

The Dragons (15-9, 7-3 WACC-Foothill) batted around the order in the first inning, with five of the first six batters reaching base. O'Dowd walked three times in the first inning and eight times in the game.

"We can't give free bases to a team like Bishop O'Dowd," Arroyo coach Eric Anderson said. "They jumped on us."

The win snapped a two-game losing streak for the Dragons, who enter next week's WACC-Foothill Division playoffs as the No. 1 seed.

"They are really understanding the whole picture of team baseball," said Bishop O'Dowd coach Chris Kyriacou about his squad. "It's not about the numbers. It's more about the letters -- the W and the L."

Nesbitt gave the Dragons a 5-2 lead when he slammed a solo home run over the center-field fence in the second inning. He finished the game 2 for 2 at the plate with two walks, two runs scored and two RBIs.

Jaycob Medina led off the second-inning with a home run smashed over the left-field fence for Arroyo (17-7, 6-4). He finished 2 for 3 in the game, as he also hit a sixth-inning double.

Bishop O'Dowd right-hander Leo Nierenberg entered the game later in the second inning and pitched 5 1/3 innings of shutout baseball. With his fastball and curveball working well, the sophomore struck out 11 batters in the win.
