10/02 Hawks vs Marines

Hawks starting pitcher: Yugo Maeda Marines starting pitcher: Haruya Tanaka

This is the opener of a two-game set (Game 1 of 2). The Hawks are in 1st (.657) riding a six-game winning streak, while the Marines are 5th (.452) and have lost two straight. The Hawks own the season series 16-6, but a gap that size is already fully priced in, so tonight is about the starters and the form of the two lineups.

Yugo Maeda has a 1.99 ERA and 2.86 FIP over 104 innings. The FIP is good, but the ERA sits well below it largely because of an 84.7% LOB%, his knack for stranding runners, and whether that keeps up is worth watching. His stuff grades above average with a 10.4% SwStr% and 28.9% CSW%. The last five starts are the interesting part: a 1.55 FIP over 27 innings means the process has actually improved, yet a .345 BABIP and 69.4% LOB% say luck went against him in that stretch. Allowing zero homers also helped keep that FIP so low. His velocity has been steady at 143-145 km/h. On the road, which applies tonight, he's been even better than at home: 1.76 ERA and 2.60 FIP over 66.2 innings.

Against the Marines he's been dominant: three starts, 19 innings, 1.42 ERA and a 25.3% K-BB%. His last two meetings (7 IP, 1 ER on 9/11; 7 scoreless on 7/19) both went seven full innings, but it's a three-game sample, so treat it as a reference point.

Haruya Tanaka is tonight's clearest case of results and process pulling apart. His season ERA is 4.08, but his FIP is 3.14, and over the last five starts his stuff has clearly ticked up: a 1.87 FIP over 32 innings with a 23.8% K-BB%, 13.2% SwStr% and 31.7% CSW%. Even so, a 60.3% LOB% in that span let runs pile up, and the sample is too small to say whether that's temporary. His velocity is steady at 148-150 km/h on average, topping out at 152-153. He's at home tonight, where he's been far better (2.84 ERA, 2.87 FIP over 44.1 innings) than on the road (5.32 ERA). Against the Hawks he has a 3.38 ERA over three starts and 16 innings, with plenty of strikeouts (21) but a high 13.2% walk rate, again a three-game sample.

The problem is the lineup he's facing. Neither lineup is confirmed, so these are projections from the last game. The Hawks' offense was already strong at a .358 season wOBA (135 wRC+), and they've exploded to a .436 wOBA with 14 home runs over the last five games, scoring 43 runs in that span. Kensuke Kondoh (.617 wOBA over the last five), Yuki Yanagita (.607) and Tatsuru Yanagimachi (.490) are especially hot. Against Tanaka they've struggled, with Ryoya Kurihara 1-for-7 and Kondoh 1-for-6, but none of these reach 10 at-bats. The Marines' offense is at its usual level, .314 on the season and .309 over the last five, but Kyota Fujiwara (.195) and Hisanori Yasuda (.074) have gone ice cold, leaving 34-homer slugger Koki Yamaguchi (.417 over the last five) to carry the middle of the order.

The Hawks have the better bullpen too: a 2.51 ERA over the last ten games against the Marines' 5.00, with similar recent workloads, 9 innings over eight relievers for the Hawks and 10 innings over seven for the Marines. Weather is a real factor. ZOZO Marine Stadium is open-air and the chance of rain is 67%, so first check whether the game goes ahead at all, and even if it does, wet conditions could play a part.

In summary, nearly every indicator points toward the Hawks: the season record, the starter's results, the lineup's form and the bullpen. But Tanaka's stuff over his last five starts (1.87 FIP, 13.2% SwStr%) is far better than his season ERA suggests. The single biggest variable is whether that stuff holds up against a Hawks lineup that has scored 43 runs in its last five games, and before that, whether the game gets played through a 67% chance of rain.
