Senga's 9.00 ERA Gets Another Start. Imanaga's Fly Ball Problem Awaits.
Kodai Senga was one of the best pitchers in baseball halfway through 2025 — seven wins, a 1.47 ERA, and a ghost fork that was generating swing-and-miss at an absurd clip. Then lumbar spine inflammation hit, and the guy who returned on June 16 is nearly unrecognizable. He's 0-5 with a 9.00 ERA across six starts, allowing seven home runs in just 24 innings. His WHIP sits at 1.88. The velocity is back at 97.9 mph, but the command is gone — 17 walks in 24 innings, or roughly one free base every inning and a half. That's not a pitcher finding his groove. That's a pitcher fighting his mechanics.
On the other side, Shota Imanaga owns a 4.26 ERA and an excellent 1.06 WHIP across 86.2 innings, but there's a fly ball problem hiding in the numbers. He's given up 17 home runs through 15 starts — nearly two per nine innings. Imanaga and Senga are a fascinating paired study: two former NPB stars, both signed to headline New York and Chicago rotations, now on opposite MLB trajectories. The Mets sit at 34-43 and are sinking. The Cubs are 40-37 and pushing for a wild card.
The 8.5 total feels light. You have a pitcher with a 9.00 ERA who can't locate his fastball on one side, and a pitcher surrendering long balls at an elite-bad rate on the other. Citi Field plays deep, but fly balls find the gaps when command abandons you. The question isn't whether to go over — it's whether the market has fully priced in how broken Senga currently is.
