YOKOHAMA, Japan (Interstat) — In a pivotal playoff clash where dominant pitching and one batter’s historic performance collided, the Yokohama BayStars seized control of their series with the Yomiuri Giants, riding a masterful start from Anthony Kay and a perfect, powerful night from Yoshitomo Tsutsugoh to a 6-2 victory Saturday evening at a packed Yokohama Stadium.

A crowd of 33,783 watched as the BayStars, now 73-67 with five ties, took a crucial step forward in the postseason, while the Giants, falling to an even 70-70 with four ties, saw their offense silenced outside of one swing of the bat.

The story of the game was written in the contrasting fortunes of the two starting pitchers and the relentless bat of Tsutsugoh. Yokohama’s Anthony Kay, the winning pitcher, delivered a commanding performance, holding the formidable Yomiuri lineup to just two hits over seven strong innings. Both hits, however, came in a costly sequence in the fourth. The two runs he allowed were earned, and he struck out eight batters while walking three to improve his record to 10-6.

His counterpart, Yomiuri’s Iori Yamasaki, was saddled with the loss despite a quality effort that saw him log six innings, allowing five hits and four earned runs while striking out six. Yamasaki’s record fell to 11-5, largely due to the damage inflicted by Tsutsugoh.

The BayStars struck first in the bottom of the second inning. With no outs, Tsutsugoh stepped in and launched a solo home run to right field, giving Yokohama an early 1-0 lead and setting the tone for his remarkable evening.

Yokohama expanded its lead in the third. Takuma Hayashi led off with a single and was moved to second on a sacrifice bunt from the pitcher, Kay. Tatsuo Ebina then delivered a clutch single to shallow left, scoring Hayashi. After a hit-by-pitch to Masayuki Kuwahara, Tsutsugoh came through again, this time with a two-out single down the right-field line to plate another run, pushing the BayStars’ advantage to 3-0.

Yomiuri’s entire offensive output for the game materialized suddenly in the top of the fourth. After a fly out, Yukinori Kishida singled to shallow right for the Giants’ first hit of the contest. The next batter, Gakuto Wakabayashi, connected on a towering two-run home run to left-center field, abruptly cutting the deficit to 3-2 and injecting life into the visiting squad.

That hope was short-lived, as Tsutsugoh extinguished it himself in the bottom of the sixth. Leading off the inning against Yamasaki, he crushed his second solo shot of the game, this one to left field, restoring Yokohama’s two-run cushion at 4-2.

The BayStars put the game out of reach in the eighth inning, capitalizing on a tiring Yomiuri bullpen. They loaded the bases with no outs on a walk to Kuwahara and consecutive singles from Keita Sano and, fittingly, Tsutsugoh. Shugo Maki then drove in a run with a single to shallow right, and Yuudai Yamamoto followed with a sacrifice fly to right field, scoring another. The two-run inning gave Yokohama a commanding 6-2 lead.

From the mound, Yokohama’s relief corps was flawless. Hiromu Ise struck out two in a perfect eighth inning, and Kohei Morihara retired the side in order in the ninth to seal the victory.

For Yomiuri, the offensive struggles were profound. Outside of Wakabayashi’s two-run homer, the Giants managed only one other hit and could not sustain any rallies, going 0 for 2 with runners in scoring position and stranding three runners on base. The loss continues a pattern of inconsistency for Yomiuri, which had split its recent two-game series with the BayStars just two weeks prior.

The victory aligned with pregame projections, as Interstat’s game simulator had predicted a 5-4 Yokohama win, and its ELO system gave the BayStars a 55.40 percent probability of victory. The combined total of eight runs sailed over the pregame over/under line of 5.0.

The two Central League rivals will resume their playoff series Sunday afternoon at Yokohama Stadium, with the BayStars looking to build on their momentum and the Giants desperate to even the series.
