The Astros and Mariners Made a Weird Trade
Most deadline trades follow a familiar coda. A team with fading hopes and eyes full of prospects gets rid of an overperforming reliever, or perhaps a soon-to-depart slugger. A contender who needs more pitching (so, all of them) gives up on its prospect-hugging ways long enough for a few to slip through its grasp. Wham-o! It’s a trade. This one is … well, it’s not that:

Kendall Graveman is definitely the aforementioned overperforming reliever. He’s been incredible this year, one of the best closers in the game. No longer a middling starter, he converted to relief in 2020, added velocity and started dominating. His 0.82 ERA is better than he’s actually been — shocker, that — but he’s cooked up an enviable mix of strikeouts and grounders, and he’s done it when it counts; he’s recorded 18 shutdowns this year (adding at least 6% of win probability) and only three meltdowns (losing 6%).
Rafael Montero? He hasn’t been that. He has 12 of those fancy shutdowns, but 12 meltdowns to match. The Mariners are 23–8 in one-run games, but it’s been because of Graveman, not Montero. In fact, they’ve swapped roles; Graveman now finishes games, and Montero sets him up. He, too, is a capable pitcher. But he’s been dicey this year, even at the underlying metric level, and that 7.27 ERA — ew!
Anyway, neither of them are Mariners anymore. The Astros snapped them both up, and they’ll fold them into their middle-of-the-road relief corps; they’ve been only 16th in baseball in park-adjusted ERA and 20th in park-adjusted FIP. Ryan Pressly has been great, but he’s a man, not an entire bullpen. Houston could certainly use the help.
