Takahiro Arai, the Central League's 2016 MVP, provided the off-the-bench heroics on Tuesday in the Hiroshima Carp's 4-3 win over the DeNA BayStars.

Moments after the BayStars had taken a 3-2 lead against the league leaders before 28,556 at Yokohama Stadium, reliever Spencer Patton (3-3) retired the first two batters he faced but couldn't finish the job.

After a flyout and a strikeout in the heart of the order, Patton walked hot-hitting Tomohiro Abe on four pitches and challenged catcher Tsubasa Aizawa in the zone.

Behind in the count, 1-2, the Carp No. 8 hitter hit an opposite-field flair down the right-field line that landed just fair before bouncing into the field seats for a fluke ground-rule double.

With the outfield playing shallow for a play at the plate should Aizawa try to score on a single, Arai's fly to left center found no-man's land, and Aizawa trotted home.

Jose Lopes opened the scoring off right-hander Yusuke Nomura (4-2) with a two-out solo homer in the first. The Carp knotted the scores in the second, when rookie BayStars lefty Haruhiro Hamaguchi allowed an infield single and walked three batters.

After another infield single and a walk in the top of the third, Abe untied the game with an RBI single, only for Lopez to plate Toshihiko Kuramoto with an infield single.

Both Nomura and Hamaguchi went six innings, when the BayStars took their second lead of the game on a long homer to center by Yoshitomo Tsutsugo. DeNA then turned the game over to Patton, who let the game get away with two outs.

Nomura got the win after allowing three runs on six hits and a pair of walks. He struck out four. A trio of relievers, Ren Nakata, Shota Nakazaki and Takeru Imamura allowed just one runner to reach over the final three innings to close out the third-place BayStars.
