Arizona Diamondbacks acquire Paul Sewald from Seattle Mariners, sources say - ESPN

The struggling Arizona Diamondbacks acquired closer Paul Sewald from the Seattle Mariners on Monday, hoping to shore up a bullpen that has faltered over the past month and taken Arizona from leading the National League West to out of a playoff spot, sources told ESPN.

While the Diamondbacks (56-50) and Mariners (54-51) have near identical records, Seattle took advantage of a thin pitching market and received three hitters in return: rookie outfielder Dominic Canzone, utilityman Josh Rojas and Ryan Bliss, a Double-A middle infielder.

With the Diamondbacks' window of contention opening, they were searching for more of a long-term solution than a rental player, and they got it in Sewald, who is under team control through the end of the 2024 season. The 33-year-old had been a stalwart in the Mariners' bullpen since joining the team in 2021, saving 52 games, and will take over the role after Arizona spent the season using a committee.

In 43 innings this season, Sewald has struck out 60, walked 14 and posted a 2.93 ERA while saving 21 games in 24 opportunities.

In the past 30 days, the Diamondbacks' bullpen posted a 6.37 ERA, better than only Washington's 7.22.

The Mariners' offense struggled this season after they made the postseason for the first time in two decades in 2022. To address it, they moved Sewald — the second time in three years they dealt their closer near the deadline, with Kendall Graveman going to Houston in 2021.

Canzone, who turns 26 next month, spent most of the season destroying Triple-A pitching with a 1.065 OPS in 304 plate appearances. In his first big league stint, he has hit .237/.293/.368, and with Jarred Kelenic on the injured list and Teoscar Hernández a trade candidate, Canzone could see regular
