Chiba Keizaidai Fuzoku rallied to beat Tohoku of Miyagi Prefecture and fastballer Yu Darvish 3-1 in 10 innings to reach the quarterfinals of the National High School Baseball Championship on Tuesday.

First baseman Yoshiyasu Kono, who came on as a late defensive replacement, singled home the go-ahead run in the top of the 10th inning before Takahiro Kawakami gave the Chiba school a two-run lead with a single at Koshien Stadium.

With two outs and a runner on third in the ninth, Tohoku third baseman Takayuki Yokota made a costly throwing error that tied the game at 1-1 in a game played in rain.

Darvish, who has been drawing keen attention from professional scouts, came within one out of pitching his third straight complete-game shutout. He gave up three runs -- two earned -- and nine hits in 9 2/3 innings with six strikeouts and five walks.

In other third-round games, infielder Shunji Sato broke a 4-4 tie with an eighth-inning RBI single and Hideaki Wakui overcame a shaky start to strike out 12 as Yokohama from Kanagawa rallied to eliminate Kochi's Meitoku Gijuku with a 7-5 victory.

Aichi's Chukyodai Chukyo came from behind three times to down Tokaidai Shoyo of Shizuoka 7-3 on a complete-game effort by Kenta Ogura.

The scheduled game between Yamanashi's Tokaidai Kofu and Seiko Gakuin of Fukushima Prefecture was postponed due to rain.
