Walbert Ureña Has Given the Angels a Rare Building Block
Ureña has pitched remarkably well for the Angels in his rookie season.
When the 2026 season got underway, who had on their bingo card that Los Angeles Angels right-hander Walbert Ureña would end up being one of the best rookie starting pitchers in baseball? Probably not very many.
With September just getting underway, Ureña currently ranks second amongst rookie pitchers (min. 100 IP) with a 2.74 ERA, trailing only Parker Messick (2.53).
Ureña was able to crack the Angels Opening Day roster after a solid spring showing but was placed into an unfamiliar relief role; he rose through the Angels system primarily as a starter. That experiment didn’t last long, as he only made two relief appearances before being optioned to Triple-A Salt Lake.
The reason why he only pitched two major league games before being sent down is that the Angels wanted to stretch him out to be a starter, then bring him back up. In an article by Rhett Bollinger of MLB.com, Angels manager Kurt Suzuki stated, “He’s gonna go down, and we’ll get him back in the rotation. We all see the stuff.”
Following two starts in Triple-A, Ureña was ready to return to the Angels’ active roster. He impressed instantly during his first career major league start on April 19 against the San Diego Padres, in which he went six innings, allowing two runs while striking out eight.
Including his first start of the season against the Padres, Ureña has totalled 24 starts and has been absolute nails across the entire 2026 campaign. He has proven to be a key contributor to an Angels starting rotation that’s seen substantial improvements this season.
As the Angels’ 2026 season dwindles down, it’s time to recap how well Ureña has pitched and how he could serve as a building block while the organization looks to reinvent itself back into a postseason contender. But first, let’s take a look at how he got to where he is now.
*Stats pulled prior to games on September 7.
An Under-the-Radar Prospect Becoming More Than Expected
Ureña entered the Angels organization as part of the 2020-21 international signing class and immediately became someone to pay attention to moving forward. He joined the club’s top 30 prospect list in 2023, per MLB Pipeline, ranking 17th within the organization.
He featured elite stuff throughout his time in the minor leagues but only relied on a three-pitch mix. Across five minor league seasons, he worked with three pitches: an upper-90s fastball, mid-80s changeup, and low-80s slider.
The pure stuff has always been there, but Ureña struggled with command that resulted in a plethora of walks. His offerings didn’t miss bats very often, resulting in minimal strikeout rates. The combination of a limited pitch mix, rough command, and low swing-and-miss numbers is why his prospect status wasn’t as high as one may have expected.
For the impressive season that Ureña has put up, you probably would think that he came up as a top prospect — pretty much the opposite in his case. It’s also why this season has been so special for him, being able to achieve way more than what was expected from him, especially considering his rookie status.
Ureña Has Undoubtedly Exceeded Expectations
Circling back to his stellar major league campaign this year, Ureña has posted an excellent 2.74 ERA and 1.21 WHIP across 131.1 innings thus far — numbers that not very many were expecting from the 22-year-old. His 3.5 bWAR ranks third on the Angels, trailing only Mike Trout (3.6) and Zach Neto (3.9).
He’s done a great job keeping the ball in the yard and limiting his opponents’ hits. The reason as to why batters are struggling against Ureña is that his stuff has limited batters to a measly 5.4% barrel rate and a minimal 35.8% hard-hit rate, while inducing groundballs at a superb 54.9% clip. Those are all traits you expect to see out of a quality pitcher.
The best part of Ureña’s game is how effective his changeup has been, hence an incredible +17 run value (100th percentile) on the pitch. Opponents are only hitting .161 against the offering, to go along with an even better .154 expected mark. The pitch has 5.3 inches of rise along with an above-average 16.8 inches of tail.
You could argue that he’s in the mix for American League Rookie of the Year, but it’ll be tough for him to compete for the award when Messick of the Cleveland Guardians has put together an even better rookie season than Ureña. Not to mention the other names in contention as well.
Is Ureña’s Current Production Sustainable?
Some might say that Ureña’s 2026 campaign has been a fluke or not sustainable, but his underlying metrics prove that he should be able to keep up his current production. Opponents as a whole have only managed a .198 batting average against him, which is only slightly lower than his .207 expected clip. His opponents have also posted a meager .314 xSLG and .302 xwOBAcon.
Further proving the point that Ureña’s production can be sustainable are his 3.42 xERA and 3.77 FIP. Now, those numbers are a bit higher than his actual 2.74 ERA, but that is a result of some continuing flaws from the minors that have carried over to the majors: a high walk rate and mediocre strikeout rate.
First of all, to be clear, Ureña’s 22.5% strikeout rate isn’t bad, and many pitchers thrive with low strikeout rates, but it is a factor in his somewhat inflated expected numbers compared to his real stats.
The more serious problem is his poor 11.8% walk rate, which ranks in just the 14th percentile. If Ureña can clean up the command and limit the free passes to a more manageable clip, he can take his game to the next level.
On the flip side, the defense behind Ureña isn’t doing him any favors. That’s a particular problem for a pitcher like him who farms groundballs. The Angels defense currently ranks 22nd in defensive runs saved, 27th in outs above average, 28th in fielding run value, and 26th in catcher framing run value, according to FanGraphs. This makes his sub-3.00 ERA all the more impressive.
Walbert Ureña Is a Key Building Block for the Angels’ Future
The type of production that we’ve seen from Ureña doesn’t come around too often, and he’s definitely a talent worth building a team around. The Los Angeles Angels organization has finally taken multiple steps forward this season, firing former general manager Perry Minasian, selling big at the trade deadline, and recently selling the team to Stan Kroenke.
Those are events that the fanbase and baseball community have been wanting to see happen for a very long time.
As the Angels look towards the future, they need to identify names from the current batch of players whom they want to keep and build around moving forward. Ureña certainly fits the bill along with players like Detmers and Zach Neto. There are certainly more, but those are definitely the big three.
With the recent overhaul to the Angels’ front office personnel and the fact that their farm system is actually now in a really good place, the light is finally starting to shine at the end of the tunnel. Hopefully, Ureña will continue to play a massive role in the Angels’ journey back to the postseason.
