10/03 BayStars vs Giants

BayStars starting pitcher: Shunya Shimada Giants starting pitcher: Haruto Inoue

This is a one-off game at Tokyo Dome (a single-game set). Second-place Yomiuri (76-63) hosts 3rd-place Yokohama (69-69). The BayStars have lost three straight, and the Giants dropped their last game 5-1 to the Swallows. The Giants lead the season series 13-11, but standings and head-to-head records are already well known and don't tell us much about today.

Shunya Shimada starts for the BayStars. He has just 19.2 innings (four appearances) this season, and his last outing was May 29 against the Lions (four innings, seven earned runs), so this is his first top-team appearance in over four months. His 5.03 ERA is worse than his 2.74 FIP, but 19.2 innings is too small a sample to lean on, and his 13.2 road innings were poor both ways (7.24 ERA, 4.04 FIP, 7.1% SwStr%). He averaged about 147 km/h through May, but after this long a layoff, his current stuff is something we'll only learn by watching. He has no record against the Giants.

The Giants send Haruto Inoue. His 2.11 ERA and 2.30 FIP over 141 innings are strong on both the surface and underneath, and a 11.2% SwStr%, 30.1% CSW% and 5.2% walk rate make for a well-rounded profile. His last five starts have been even better, a 1.48 FIP and 23.9% K-BB% over 35 innings, and his last two outings were eight scoreless innings and 7.2 innings of one-run ball with ten strikeouts. His velocity is holding at 148-150 km/h late in the season. At home, where he pitches today, his results (2.73 ERA, 2.51 FIP over 66 innings) are a touch behind his road numbers, but the FIP gap is small.

The starter-versus-opponent matchup tilts heavily toward Inoue. Against the BayStars this season he has a 0.88 ERA and .149 opponent average over five starts and 41 innings, going at least six innings with two or fewer earned runs every time. A .196 BABIP says he's had some luck, but five starts and 41 innings is a fairly large sample for a head-to-head split, and his 1.70 FIP shows the work behind it was strong too.

Neither lineup is confirmed, so these are projections based on each team's previous game. The BayStars' offense has gone cold, from a .335 season wOBA to .270 over the last five games with just one home run. Shugo Maki, a 30-homer hitter, has a .137 wOBA in that span and Ryuki Watarai .176, with only Takeru Furuichi (.456) doing much. Their history against Inoue isn't encouraging either: Maki is 0-for-11, Keita Sano 3-for-17 and Yoshitomo Tsutsugo 0-for-5, with only Watarai (4-for-12) faring well. The Giants' offense is running at its usual level (.307 wOBA for the season and over the last five), though with a low .212 average. Richard Sunagawa is hot with two homers and a .576 wOBA over the last five, while Go Matsumoto (.122) and Takumi Ohshiro (.217) are cold.

The Giants have the better bullpen. Their relief ERA over the last ten games is 1.91 against the BayStars' 3.99, and recent workloads are similar (11.3 innings across ten Giants pitchers, 8.7 across nine for the BayStars). It's a dome game at Tokyo Dome, so weather isn't a factor.

In summary, the starting matchup - Inoue, consistent all season and dominant against the BayStars (0.88 ERA over 41 innings), against Shimada, making his first appearance in four months - tilts clearly toward the Giants. The BayStars' bats are cold and the Giants have the better bullpen as well. The biggest variable today is whether Shimada can survive the early innings in his return. If he falters early, a BayStars lineup that struggles to score off Inoue will have a hard time catching up; if he holds up longer than expected, it could turn into a surprise pitchers' duel against a Giants offense hitting just .212 lately.
