09/27 Swallows vs Giants

Swallows starting pitcher: Takahashi Keiji Giants starting pitcher: Ogasawara Shinnosuke

This is a one-off game (1 of 1). The 2nd-place Giants (.544) went 1-3 on a four-game trip to Hiroshima and have lost two straight, while the 4th-place Swallows (.437) have won two in a row against the Dragons. The Giants lead the season series 13-10.

Takahashi Keiji has a 3.94 ERA and 3.74 FIP over 89 innings, and a high .327 BABIP means his results have been a little worse than his process. His stuff is good, with an 11.3% SwStr%, 29.4% CSW% and a steady 148-149 km/h average velocity. His last five starts (28.2 innings) produced only six runs, but his FIP in that span is 3.81, similar to his season mark, with a very high 98.7% LOB%. He also walked 11 (9.1% BB%), so he was not as dominant as the results suggest. On the road, where he pitches today, he has a 4.33 ERA and 3.28 FIP over 35.1 innings, with a high 11.7% walk rate being the weak spot.

Ogasawara Shinnosuke has a 2.49 ERA and 2.78 FIP over 61.1 innings, so both results and process are strong. With a 4.5% walk rate and 31% CSW%, he builds counts with command. His average velocity has actually risen from 143.7 km/h in late August to 145.6 recently. Over his last five starts (28.1 innings), however, his SwStr% has fallen to 5.6% (9.1% on the season) and his FIP has crept up to 3.29. That stretch includes a nine-inning shutout of the Carp on 9/6, but also two starts that ended after four innings. At home, where he pitches today, he has a 2.67 ERA and 2.37 FIP over 30.1 innings, with an excellent 1.7% walk rate.

The head-to-head samples are small on both sides. Takahashi has a 6.39 ERA in three starts (12.2 innings) against the Giants, but one 2-inning, 6-run outing on 8/8 drives most of that; in the most recent meeting on 9/20 he allowed one earned run in 5.2 innings. Ogasawara has a 3.97 ERA with two homers allowed in two starts (11.1 innings) against the Swallows.

Neither lineup is confirmed yet, so these are based on each team's previous game. The momentum is with the Swallows. Their last-five team wOBA is .338, above their season .305, and they have scored at least four runs in all five games. Maruyama Kazuya (.661 wOBA over the last five, 150.9 wRC+) and Nishimura Ruito (.454) are hot, and Masuda Shu is 3-for-5 against Ogasawara, while Nagaoka Hideki (.161) has cooled off. The Giants' last-five team wOBA is .252, well below their season .314; they scored two runs or fewer in all four games at Hiroshima and have just one homer in five games. Dalbec Bobby, who has 25 homers, is 3-for-7 against Takahashi and Ohshiro Takumi is 4-for-4, while Sasaki Shunsuke (.154) and Matsumoto Go (.211) are struggling. All of these are small samples.

The Giants clearly have the better bullpen, with a 1.23 ERA over the last 10 games against 3.92 for the Swallows. Recent workloads are 6.3 innings by 8 pitchers for the Giants and 8.7 innings by 7 for the Swallows. The game is at Tokyo Dome, so weather is not a factor.

In summary, Ogasawara has a slight edge in underlying quality and the Giants' bullpen is clearly stronger, but the offensive trends run the opposite way, with the Swallows hot and the Giants cold. The biggest swing factor is whether Ogasawara, whose swing-and-miss rate has dropped lately, can get through the early innings against a hot Swallows lineup led by Maruyama and Nishimura and hand the game to the Giants' strong bullpen.
