The read
It's deadline day at the Mets' park, and New York swapped out their starting pitcher before anyone even loosened up. Freddy Peralta was supposed to have this one. Instead he's sitting by a phone waiting to find out where he's playing next, and Kodai Senga is heading to the mound at a place that's given him fits all year. That's the whole game. Everything else is window dressing.
Senga hasn't pitched in the majors in over a month. He's made only a handful of starts this season, never got deep into any of them, usually out before the middle innings, and he's been noticeably worse at home than on the road. I don't think he's finished — that splitter of his still makes hitters look silly, and most pitchers would give up a year's pay for it — but a guy coming off a back injury with over a month of rust and no command is a three-inning guy on his best day. So New York needs most of the game out of a bullpen that just traded away an arm this morning, lost Cionel Pérez to a forearm injury, and has already used Devin Williams two nights in a row. They're patching this together with minor leaguers while the front office tries to sell off anything not nailed down.
Miami isn't playing great either, and I won't pretend they are. Their bats have been cold for a couple weeks, and Janson Junk really struggles against lefty hitters — and this Mets lineup, with Ewing, Benge, Young, Baty, plus Lindor and Polanco batting from that side, is built to take advantage. That's why I'm not making this a big play. But Junk should get you into the middle innings, there are fresh arms behind him, and he's throwing in front of a crowd of scouts with his own future on the line. The betting line barely budged when the Mets swapped pitchers. That's not nearly enough. At this price I'll take the team that actually knows who's pitching the middle of the game.
The full analysis
Deadline Friday at Citi Field, and the Mets changed pitchers before anybody threw a warmup pitch. Freddy Peralta was supposed to have this game. Instead he's somewhere waiting on a phone to ring, and Kodai Senga is walking out to a mound he hasn't solved all season. That's the whole game right there. Everything else is decoration.
Senga hasn't started a big league game since June 23. Seven starts this year, the longest of them 5 2/3, most of them finished before the fifth, and at this ballpark he's been meaningfully worse than he's been anywhere else. I don't think he's cooked — the forkball still misses bats at a rate most starters would trade a year of salary for — but a man coming back off a back problem with five weeks of rust and no feel for the zone is a three-inning proposition on a good night. Which means New York needs six innings out of a bullpen that woke up this morning one arm lighter after the Minter deal, put Cionel Pérez on the shelf with a forearm strain, and has already run Devin Williams out there two nights running. They're taping this one together with Syracuse call-ups on a day the front office is trying to sell everything that isn't bolted down.
Miami isn't humming, and I'm not pretending otherwise. The bats have gone quiet for two weeks, and Janson Junk has a genuine problem with left-handed hitters that this lineup — Ewing, Benge, Young, Baty, plus Lindor and Polanco turning around — is built to go after. That's why this isn't a big number for me. But Junk gives you five, there's a clean set of arms behind him, and he's throwing in front of a dozen scouts with his next address on the line. The market moved eight cents on a Peralta-to-Senga swap. That's not enough. At even money I'll take the club that knows who's pitching the middle innings.

Props on this game
6Kodai SengaOVER 1.5 Pitcher Earned Runs Pitcher Earned Runs-110
WActual 3
An 8.85 ERA isn't one bad week — it's been the whole season, and the pitch-level numbers back it up. Hitters have a .420 expected weighted on-base average against his fastball and .608 against his cutter, and those two pitches are more than half of what he throws. His forkball is the only real swing-and-miss weapon in the mix.
He's allowed two or more earned runs in six of his last eight starts, and tonight he's pitching at the park where his numbers are worst all season. The lineup across from him hits left-handed from the top to the middle of the order — Hicks, Stowers, Conine, Marsee, Mack — and left-handed bats have put up a 1.032 OPS against him this year. I don't need a total collapse for this to cash.
I need one bad inning, and that's been the rule with him lately, not the exception.
Griffin ConineOVER 1.5 Total Bases Total Bases+184
LActual 1
Conine's swinging it as well as anyone in that lineup right now — four home runs and a .947 OPS over his last two weeks. He's left-handed, walking into a matchup against a pitcher who has had no answer for left-handed hitting all season: a 1.032 OPS allowed with six home runs surrendered in well under 200 at-bats against lefties. Senga's two most-used pitches, the four-seamer and the cutter, are both getting hit hard by everybody who steps in against him, and Conine's contact right now is loud enough to take advantage of a mistake. He doesn't need a monster night to clear two bases — one extra-base hit does it — and he's been doing exactly that more often than this price accounts for.
Kyle StowersOVER 0.5 Home Runs Home Runs+550
WActual 1
Stowers has been the hottest hitter on either roster this week — three home runs in his last seven games, squaring balls up at nearly 97 miles an hour off the bat in that stretch with four barreled balls in sixteen chances. He's left-handed, and Kodai Senga has been a completely different pitcher against lefties this year — they carry an OPS over 1.000 against him, more than 150 points higher than what right-handers have managed.
Stowers already has a home run on his card against Senga in a small four-at-bat sample. Exit velocity, barrel rate, and the platoon split all point the same direction.
Betting the over.
Griffin ConineOVER 0.5 Home Runs Home Runs+700
LActual 0
Conine is carrying the best power surge on the board tonight — four home runs in his last fifteen games, and a .991 OPS with nine homers against right-handed pitching this season in well under a hundred at-bats. Kodai Senga leans on his four-seamer more than any other pitch he throws, and it's the one that's been hit hardest against him all season, with opponents batting over .330 on it.
Conine's own numbers against the four-seamer back that up — over .300 with a .696 slugging mark on the pitch this year. A hot bat matched against a pitcher's clearest weakness, at seven-to-one.
Betting the over.
Francisco AlvarezOVER 0.5 Home Runs Home Runs+500
LActual 0
Alvarez has three home runs in his last fifteen games and he's been driving the ball hard in that stretch — five hard-hit balls and two barrels in his last ten balls in play. He's a right-handed hitter with real over-the-fence power against right-handed pitching this year, and Janson Junk's slider and curveball have both been getting hit hard all season, the curveball especially — opponents are batting .333 off it.
The wind is blowing out to left field at Citi Field tonight, which sits right in Alvarez's pull path. It's the shortest price on this board for a reason — the market's seeing the same form I am — but I still like it.
Betting the over.
Francisco LindorOVER 0.5 Home Runs Home Runs+650
WActual 1
Lindor's running hot — two home runs and eight RBIs in his last seven games, three homers and twelve driven in over his last fifteen, and the contact quality backs it up with three barreled balls in his last twenty balls in play. He's a switch-hitter, which means he bats left-handed against Janson Junk tonight, and Junk has been a completely different pitcher against lefties this year — an .875 OPS against, compared to well under .600 against right-handers. That's about as clean a platoon matchup as this board offers. Betting the over.
