The MLB season got underway on Wednesday, which means the time that teams had to improve their rosters has come and gone. The offseason is behind us, and whether or not your favorite team did enough to contend for a World Series championship is about to be seen.
Some fanbases may be thinking, "Absolutely not. There's no way my team did enough. They only signed [insert surprisingly valuable player here] and [insert other player with no big-name notoriety] here." But it is exactly those moves that build division winners. They may not win the World Series. Let's be honest, that will always and forever be the Los Angeles Dodgers, but competitors are built on underappreciated contracts and value.
Here are five offseason moves that could wind up being more impactful than we'd initially thought.
Most underrated moves of the 2025-26 MLB offseason
5) Mike Burrows traded to the Houston Astros
Despite many fans believing the Houston Astros were going to take a step back last year, the team nearly reached the postseason with an 87-75 record. That record came despite the team's back-end of the starting rotation posting a 4.69 ERA.
One of the team's top starters, Framber Valdez, left in free agency, joining the Detroit Tigers. Thusly, many experts believed the Astros would be trotting into 2026 with one of the worst rotations in baseball. But the team made some sneaky good moves this offseason, including the acquisition of Japanese pitcher Tatsuya Imai and the trade for the Pirates' Mike Burrows.
Burrows isn't a name with a ton of notoriety, but he is a solid middle-of-the-rotation arm, which is exactly what Houston needs. The 26-year-old posted a 3.96 ERA in 96 innings a season ago, but more importantly, he boasted one of the best changeups in baseball, per Baseball Savant.
This is a guy who has great stuff. He may not be an elite talent that wins a championship, but he isn't expected to be that. He is expected to be a No. 3 or 4 starter, and Burrows provides potential for more. He also has six years of team control under his belt.
4) Harrison Bader to the San Francisco Giants (2 years, $20.5 million)
Bader may be entering his age-32 season, but he hasn't slowed down, it seems. Last year was the best season of his career offensively, and it doesn't appear to be a fluke. Skeptics might point out that most of his projected stats say that he exceeded expectations a season ago, with just a .220 expected batting average and .295 xWOBA, putting him on pace with his prior seasons.
However, some underlying metrics point to a potential resurgence for Bader. Most notably, his bat speed. The 32-year-old increased his swing speed by nearly two ticks a season ago, pushing him from the 38th percentile in MLB to the 71st percentile in just one year. It's no shock that that coincides with his 17 home runs, the most of his career for a single season.
The Giants have long struggled to find consistency in their outfield. However, their starting trio of Jung Hoo Lee, Heliot Ramos, and now Harrison Bader has the potential to be one of the most complete in baseball.
3) Sonny Gray traded to the Boston Red Sox
People look at Boston, notice they lost Lucas Giolito and gained Sonny Gray and think they are in a worse position than they are now. It is easy to think that. It makes sense, but there is a lot to like about Sonny Gray despite him losing nearly a mile per hour on his fastball a season ago and entering his age-36 season.
The first positive note is that Sonny Gray's expected stats were nearly a full tick lower than what his ERA ended up being (4.28). His FIP (3.39) and xERA (3.88) were both better than what Giolito produced a season ago. Not only that, but Gray also posted a 5.29 strikeout-to-walk ratio, the best in the National League. Combine those two statements and Gray is someone primed for a bounce-back.
But the most obvious positive for Gray is that he likely won't get as unlucky as he did last year. In 2025, Gray had six starts in which he gave up at least six runs in the first inning. Prior to 2025, he only had three such starts in 2024, and only one such start in 2023, 2022, and 2021. Even if, in 2025, Gray matched his mark from 2024, his ERA likely would've been easily under 4.0 last season.
Keep in mind, Gray is still very good at getting hitters to chase outside the zone, posting a 31.2% chase rate last year. He's also very good at creating ground balls, ranking in the 66th percentile with a 45.1% rate in 2025. There's a lot to like about Gray going into next year.
2) Cody Ponce to the Toronto Blue Jays (3 years, $30 million)
If the World Baseball Classic has shown us anything, it's that Japanese and Korean baseball are not to be taken lightly. The NPB and KBO have produced some very impactful MLB players over the years.
Ponce was KBO MVP last season, with a 1.89 ERA across 180.2 innings while striking out 252 batters. Let those numbers speak for themselves.
Sure, Ponce has never found success in the United States, but this time feels different. Most notably, his fastball has increased in velocity substantially from his 2021 stint with the Pirates. Back then, he was only hitting 93. Now, he's routinely touching 97.
The Blue Jays certainly made their splash in the rotation when they added Dylan Cease, but Ponce is someone who is coming into the year with back-end expectations and could provide much more for a rather team-friendly price.
1) Brad Keller to the Philadelphia Phillies (2 years, $22 million)
No one ever gets giddy over signing a middle reliever, but Phillies fans should be ecstatic at the addition of Keller. Last year, the 29-year-old had a staggering increase in fastball velocity, adding nearly 3.5 mph to his fastball from 93.8 to 97.2 in just one season. That velo was a major factor in Keller's career year, in which he posted a 2.07 ERA.
Oh, but it's not just his fastball you should be excited about. Keller's sweeper produced an incredible .067 batting average against with a 45.8% whiff rate. Yes, those numbers are even better than they sound.
He was absolutely lights out against right-handed batters and still very serviceable against lefties. He'll be a tremendous addition to the Phillies bullpen, making it that much easier for the team to get to Jhoan Duran in the ninth innings with the lead intact. Given that Philadelphia's bullpen ranked 20th in baseball with a 4.25 ERA last year, Keller is a steal at $11 million a year, helping fix Philadelphia's biggest weakness from a season ago.
