Sunnyside junior Lazaro Nuñez had come through with two clutch hits already.

So when he came to the plate in bottom of the seventh inning Saturday with the bases loaded and two outs, there was a feeling in the air that he would do it again.

Blue Devils coach Gabriel Moraga wasn't surprised at all when he did.

Nuñez blooped a walk-off single into right field to give No. 15 Sunnyside a 7-6 win over visiting Sierra Vista Buena in the Division I state baseball tournament first round.

"It was pretty nerve-racking, but I just wanted to stay cool," Nuñez said. "Even if I didn't get the hit, we had defense next and we would have clutched up again."

The Blue Devils (18-10-1) advance to face second-seeded Tucson on Tuesday.

Buena (19-11) scored five runs in the third inning with a pair of home runs, including a three-run shot by Matthew Duce. But the Colts, in the playoffs for the first time since 2003, were held to one run outside that inning.

Nuñez went 3 for 4 with four RBIs, including an RBI double in the fourth and a two-run single in the sixth that put the Blue Devils ahead 6-5.

"Luckily we just had timely hitting and the right kid at the plate each time," Moraga said. "That kid will battle for us."
