Mike Hazen has developed himself a reputation for making his impact moves at some rather unexpected moments. Jalen Beeks is no exception. Despite having solid results for four of the previous five seasons, Beeks looked first to the Houston Astros on a minor league deal for the 2025 season. Less than two weeks later, he was released. Then, the day before Arizona took the field for their first game of the season, Hazen took a chance on the veteran left-hander.

Beeks has spent the majority of his career flying under the radar. Such tends to be the fate of many of the relievers that Tamp Bay cuts loose, as they did with Beeks in 2023. Beeks is of unassuming size by baseball standards. He doesn’t throw particularly hard, though he has respectable speed in the low-to-mid 90s. Beeks arrived on Arizona’s roster with a history of below average strikeout rates and above average walk rates. Take all together, there were plenty of reasons for the Arizona fandom to view the Beeks signing with a heavy dose of skepticism. As it turned out, Beeks was arguably the most reliable relief arm for the 2025 season. Unlike some of his peers, he did not miss time to injury or suspension. He dropped right into the 26-man roster, put his head down, and got to work.

Used mostly in middle relief situations, Beeks did not accrue many holds or saves. In fact, he only had one save all season long, despite the numerous bullpen arm injuries. That save came on 4 May, in extra innings against Philadelphia.

Beeks was solidly reliable all season long. He did not go through the wild ups and downs commonly associated with relief pitching. His performances, most of them being one-inning affairs, were eerily consistent. Only once all season did he hit something of a hurdle. This came at the end of June. It was then, on back-to-back nights, that Beeks had his “meltdown period”. Over the course of two games against the Miami Marlins, Beeks managed only one total inning of work, while allowing eight runs on five hits and four walks. In the first outing, he had his bacon saved by Ryan Thompson, before Shelby Miller ended up blowing the save in one of Arizona’s many bullpen meltdowns. The next night, Beeks took the blown save and the loss.

Come September, when Arizona was charging hard for a playoff berth, Beeks showed up when called upon. He only allowed 2 runs to score in the month, spread out over nine appearances. In those, he only allowed three hits and he didn’t walk anyone. For a low-to-medium leverage reliever eclipsing 60 appearances on the season, that is the sort of performance to take to the bank.

Beeks was granted free agency when the 2025 season concluded. He remains unsigned as of this writing, despite the flurry of relievers being signed by clubs across the league. At age 32, with yet another solid season under his belt, Beeks will almost certainly find another MLB contract before spring rolls around. His age and his peripheral numbers may continue to limit him to one year deals, but there are plenty of scenarios that could see Beeks landing a two-year deal as well. Arizona still has work to do on its bullpen. Beeks is nothing special, but he is competent. This raises the possibility of Mike Hazen establishing a reunion with the veteran left-hander. But, such a move will depend on cost and also on what other moves Hazen has up his sleeve for this winter. Beeks will almost certainly be toeing the mound for a Major League team in 2026. It just remains to be seen which one.
