As the reliever market picked up over the last week, two right-handers, both former closers, found new homes in the Central divisions. First, last Wednesday, Paul Sewald agreed to a one-year deal with the Cleveland Guardians. Then, on Sunday, Ryan Pressly waived his no-trade clause in order for the Houston Astros to send him to the Chicago Cubs for the final guaranteed year of his contract.
While both of these pitchers are likely past their peaks in terms of stuff, they’ll look to continue being contributors with their new clubs. Let’s examine the potential impact of these moves and discuss how the two pitchers will fit into the bullpens of their new teams.
Sewald Joins Elite Cleveland Bullpen
Coming off a down year relative to his previous three seasons, Sewald’s deal with the Guardians is for one year and $6 million, with a $10 million mutual option for 2026. The move solidifies the middle part of their bullpen, which already was one of the best in the majors. With Emmanuel Clase, Cade Smith, and Hunter Gaddis anchoring the group, Sewald will occupy a lesser role than he’s held over the last few years. That’s not a bad thing for him, as he can work to return to form without the pressure of having to deliver in high-leverage innings.
As velocities have increased over the years, and hitters have adapted to them, the margins for error for pitchers living in the low-90s band have grown thinner and thinner. What we saw from Sewald last season is a good example of what happens when pitchers with such a profile lose even just one tick on their fastballs.
From 2021-23, a three-year stretch during which Sewald was one of the better relievers in baseball, his four-seamer ranged from 92.2 mph to 92.5 mph. It was extremely consistent on that front. Then, in 2024, that number dropped down to 91.4 mph on average, and with that, his performance also dropped. Here is a quick summary of how Sewald’s performance on his heater regressed last season:

As his fastball velocity fell last year, Sewald saw a sharp decrease in its effectiveness by both whiffs and overall performance. This could be related to the pitch’s location and its release angle; over the last four seasons, he’s been throwing his fastball progressively higher and higher in the zone and releasing it closer to the middle of the pitcher’s mound. Combine that with a dip in velocity and, suddenly, the pitch was just more normal than it had been in the past.
Another problem for Sewald last year was his sweeper, the pitch that was most responsible for turning him into a high-leverage reliever upon joining the Mariners in 2021. His overall numbers with it suggest it was still a weapon — he held opponents to a .196 average (.214 xBA) and a .214 wOBA (.258 xwOBA) against it — but a closer look tells a different story.
During his aforementioned three-year stretch of excellence, he was comfortable throwing his sweeper to both lefties and righties as a way to keep them off his fastball. In each of those three seasons, he threw his sweeper at least 45% of the time against righties and at least 35% of the time when facing lefties, and it was effective against both sides. That’s especially important because Sewald is mostly a two-pitch pitcher. Last year, however, lefties teed off on his sweeper. Check this out:

So what changed? Perhaps some of it can be attributed to his diminished fastball velocity, which has cut the velocity gap between his fastball and sweeper to 8.3 mph, down from 9.7 in 2022. Except, the velo difference between the two pitches was also 8.3 mph in 2023, and that season both pitches were still effective against lefties and righties. The greater issue here seems to be the same thing that threw off his fastball: his release point, which also shifted more toward the middle of the mound when throwing his sweeper. As a result, he struggled to command his sweeper in 2024, as you can see in these two heat maps. The first one is from 2023, the second from 2024.
He started throwing the pitch more in the middle plate and less often out of the zone. Even with lesser command, he could still keep righties at bay with his sweeper because the pitch breaks away from them. Against lefties, though, he has less margin for error with his location. Sweepers that remain in the zone against lefties break nicely into their bat paths. That’s not a recipe for success.
It’s worth noting that some of Sewald’s struggles in 2024 could be injury-related, as he dealt with both neck and oblique injuries that could’ve caused his dip in velocity. These ailments might also explain his change in location and horizontal release point, as the neck and oblique muscles are especially important for a pitcher’s upper-body mechanics. Sewald turns 35 in late May, so some of his diminished stuff could be attributed to aging, but if he is healthy, we should expect him to have some sort of rebound — even if he doesn’t get back to the peak performance from his days with the Mariners.
Pressly Takes Over as Cubs Closer
For most of the offseason, the Astros have been trying to trade Pressly to shed some salary, and as they revived their efforts to re-sign Alex Bregman last week, moving Pressly seemed to become an even greater priority. Of course, Houston has not yet brought back Bregman, but either way, trading Pressly gave the Astros more financial flexibility.
Houston sent over $5.5 million to cover Pressly’s salary this season, but nothing if his contract vests for 2026. The Cubs sent back Juan Bello, a 20-year-old pitching prospect who was recently ranked no. 31 on the Cubs’ prospect list. Bello is a 35+ FV starting pitcher who, according to our prospect writers Eric Longenhagen and Travis Ice, “has enough projectability and existing stuff to be forecast in a depth starter role, but he’ll need to harness his secondaries in the zone more often to consistently get more advanced hitters out and turn over a lineup.”
The 36-year-old Pressly had been a valuable member of the bullpen since the Astros traded for him in late July 2018, and during the same three-year stretch in which Sewald shined, Pressly emerged as one of the top closers in the American League. However, Houston’s signing of Josh Hader before last season relegated Pressly to a setup role and ultimately made him expendable this offseason. Astros GM Dana Brown said earlier today that the Hader signing and Pressly’s corresponding demotion in the bullpen pecking order caused a “fracture” in his and Pressly’s relationship. Now with the Cubs, Pressly is expected to return to closing games.
Similar to Sewald, Pressly is coming off a season with a notable decrease in velocity, from 94.7 mph in 2023 to 93.8 mph last year. His diminishing fastball didn’t exactly come as a surpsise, though. In 2022, batters posted a .402 xwOBA against his four-seamer, and in response, he cut its usage from 32.9% that year down to 23.1% in 2023. He leaned more on his slider, which for years has been his best pitch by run value by a wide margin. It’s odd, then, that he used his four-seamer more often than any other pitch in 2024. This pitch mix shift didn’t pay off, as opponents slugged .500 against his heater with a .371 wOBA and a .365 xwOBA, compared to their .333 SLG, .276 wOBA, and .271 xwOBA against his slider. I imagine Chicago will get him back to throwing primarily sliders again next season. For some more context, here is a three-year snapshot of Pressly’s Stuff+ and usage for his three main pitches:

Relievers who switch teams looking for bounce backs are always fun stories to follow. Both Sewald and Pressly are in the later stages of their careers but have an opportunity to be important contributors on contending clubs. I’ll be paying attention to any potential adjustments they make come spring time.
