10/10 BayStars vs Giants

BayStars starting pitcher: Katsuki Azuma Giants starting pitcher: Haruto Inoue

The third-place BayStars (.507) open a three-game set against the second-place Giants (.543) at Tokyo Dome. The season series is about as even as it gets at 12-13 from the BayStars' side, but the two clubs are heading in opposite directions: the BayStars have won two straight while the Giants have dropped two in a row. The Giants' bats in particular have gone quiet, scoring just 2, 1 and 2 runs over their last three games, and the most recent meeting was a 5-2 BayStars win in this same building on October 3.

This is a matchup of aces. Azuma has a 2.40 ERA and 2.87 FIP over 161.1 innings, so his results and underlying numbers line up reasonably well. He isn't an overpowering arm (10.1% SwStr, 28.8% CSW), but a 4.4% walk rate lets him chew through innings, and he has actually been better on the road (73 IP, 2.34 ERA, 2.11 FIP, 2.5% BB). His last five starts tell a slightly different story, though: a 3.05 FIP and 1.34 WHIP, with the walk rate climbing to 7.4%. His last two outings in particular (Carp and Dragons) saw his SwStr% drop to 5% and 8.3% while he issued seven walks combined. His average velocity has held steady at 143-145 km/h, so this looks more like a command wobble than a stuff problem. An 84.2% strand rate has kept the damage down, but whether that keeps up is something to watch.

Against the Giants, however, it has been a completely different pitcher. In four starts against them this season he is 4-0 with a 1.33 ERA over 27 innings, 28 strikeouts against a single walk, and a 32.7% CSW. Four starts is a small sample, but he has gone at least six innings with two or fewer earned runs every time, so the matchup has clearly suited him.

On the other side, Inoue has the better underlying profile of the two: a 2.02 ERA and 2.26 FIP over 147 innings, a steady 11.2% SwStr and 30.3% CSW, and a fastball that is still sitting 148-150 km/h and touching 153 late in the season. His last five starts have been even sharper than his season line (34 IP, 1.56 FIP, 0.82 WHIP, 24% K-BB). At home, where he pitches today, he owns a 2.50 ERA and 2.40 FIP over 72 innings - a touch higher than on the road, but still very solid.

His numbers against the BayStars are almost absurd: a 0.77 ERA and .139 opponent average over five starts and 47 innings. That said, a .186 BABIP means not all of that is skill - he has had some batted-ball luck on his side. Still, in the last meeting on October 3 he threw six scoreless innings allowing one hit, and took the loss only because his offense gave him nothing.

Neither lineup is confirmed yet, so this is based on each team's previous lineup. The BayStars have one of the league's better offenses on the season (.333 team wOBA, 125 wRC+), but it has cooled off sharply to a .286 wOBA over the last five games. Their key bat Shugo Maki is hitting .182 over that stretch and is 0-for-13 career against Inoue, and Yoshitomo Tsutsugo is 0-for-7 against him, so this is a tough matchup on paper. Ryuki Watarai has been the exception at 5-for-14 (.357) against Inoue, though that is only around 15 plate appearances. The Giants' offense was already weaker on the season (.308 wOBA) and hasn't woken up either, batting .186 with a .297 wOBA over the last five. Cleanup hitter Takumi Oshiro is in a .111 slump, and while Richard Sunagawa is hot (.505 wOBA, two homers over the last five), he is a .176 hitter on the season, so expectations should stay modest.

The bullpens are close. The last-10-game ERA is 3.27 for the BayStars and 3.18 for the Giants, and recent workload is 11.7 innings across eight arms for the BayStars versus 14 innings across eleven for the Giants - slightly heavier for the Giants, but not to a worrying degree. Tokyo Dome takes weather out of the equation.

In summary, with both offenses running cold, this sets up as a classic pitchers' duel between two of the best starters in the league. Inoue has the edge in underlying numbers and current form, while Azuma brings a proven track record against this Giants lineup. The single biggest variable is whether Azuma's recent command wobble (seven walks and a falling SwStr% over his last two starts) carries into this game - if he brings the same control that allowed just one walk against the Giants all season, a low-scoring, tight game looks likely.
