2. Aroldis Chapman
Chapman has turned out to be a great addition for Texas since we acquired him from the Royals in late June. He's helped solidify the back of the bullpen and has been a solid closing option when needed, notching 4 saves, a 3.21 ERA and 49 strikeouts in 28 innings with the Rangers.
He's going to be a free agent this winter, however, and he'll likely be looking for a substantial raise after settling for a one-year, $3.75 million deal for 2023. He may want a multi-year deal as well to get some job security after his impressive rebound performance this season.
Chapman is going to be 36 next season, however, which makes him a risky investment. He's also a serious injury risk given how hard he throws, which is going to catch up with him at some point.
His velocity hasn't fallen off yet, but with the kind of contract he's likely to command you'd rather give up on him a little bit too early than to find out you do it too late and are on the hook for paying him more than he's worth.
The flame-throwing lefty can't keep topping 100 on the radar gun forever, and you don't want to be the team stuck with him when he stops. Chapman has been the perfect rental, but it doesn't make much sense to sign him in free agency and bring him back.
