Dennis Santana was one of the Pirates’ most reliable relievers in 2025, but his command has disappeared this season and his roster spot could be in danger. Alex Stumpf breaks down what has changed, whether a mechanical adjustment or different pitch mix can help and why getting the old Santana back would be a major boost before the trade deadline.

Chapters
Key takeaways
1
Getting Dennis Santana back to his 2025 form would add as much to the Pirates' bullpen as almost any deadline trade.
Alex Stumpf
2
The Pirates wouldn't have traded David Bednar last year if they hadn't trusted Santana to take over the ninth inning.
Alex Stumpf
3
Santana can't blame bad luck this year. His ERA has jumped to 5.80 and his expected ERA is about 5, so he simply hasn't pitched well.
Alex Stumpf
4
The most important fix is throwing strikes. His zone rate fell from 54.9% to 44.1% and his walk rate went from 6.3% to 11.7%.
Alex Stumpf
5
Stumpf isn't giving up on Santana, but he's on the clock. If the Pirates add relievers at the deadline, his roster spot could be at risk.
The Pittsburgh Pirates need to add relievers this trade deadline if they are serious about making the postseason.
Alex Stumpf
No way around it.
Alex Stumpf
It's also unrealistic to expect them to trade for six or seven relievers.
Alex Stumpf
They need internal improvement also.
Alex Stumpf
And if they could somehow get Dennis Santana to find his 2025 groove, that would be as big of an addition to this bullpen as almost any trade.
Alex Stumpf
Is there any hope that he can turn this season around?
Alex Stumpf
Good morning and welcome to OffBeat here on North Shore Nine presented by FanDuel.
Alex Stumpf
My name is Alex Stumpf and this is a daily look at your Pittsburgh Pirates.
Alex Stumpf
Hope you all enjoyed that Pirateless All-Star game.
Alex Stumpf
As we rev up for the second half of the season, I'm going to be taking a look at three players who I think really are going to be pivotal to seeing if this team can get over the hump.
Alex Stumpf
If they could become a postseason club.
Alex Stumpf
And one of those guys is Dennis Santana.
Alex Stumpf
I broke news last week about how the Pirates were calling up Antwone Kelly and Thomas Harrington.
Alex Stumpf
Neither are still up in the major leagues right now, so it wasn't a huge bullpen move.
Alex Stumpf
It was just get some fresh arms before the break.
Alex Stumpf
And I cannot believe, really, how many people were quote-tweeting and replying and reposting saying Dennis Santana has finally been DFA'd.
Alex Stumpf
It's like, no, this wasn't the move for that.
Alex Stumpf
Konnor Griffin is very clearly going to go on the 60-day IL and it will probably be Cam Sanders who gets DFA'd because he can't be optioned anymore without being exposed to waivers.
Alex Stumpf
Seems like a pretty understandable move.
Alex Stumpf
Dennis Santana wasn't DFA'd.
Alex Stumpf
And, candidly, I don't think he's right on that line of being DFA'd right now.
Alex Stumpf
I think the team wants to give him a little more runway.
Alex Stumpf
They want to see what he can do.
Alex Stumpf
Because up until that Brave series, he had been on a streak of 10 outings, 10 scoreless outings out of his last 12 outings.
Alex Stumpf
And Don Kelly had been talking about how he felt the stuff was playing better, how he had looked better.
Alex Stumpf
And then he had just a horrible series against Atlanta.
Alex Stumpf
That ninth inning in the series finale, that 3-1 pitch to Mike Yastrzemski, that was about as predictable an outcome as I think I've seen from a pirate reliever this year.
Alex Stumpf
He was forced to go in with a fastball and Yastrzemski was not going to miss it.
Alex Stumpf
And it went a long way, and it was a game-clinching grand slam.
Alex Stumpf
And that's disappointing for a multitude of reasons.
Alex Stumpf
The biggest being, I actually agreed with Kelly.
Alex Stumpf
Up to that point, I thought maybe he was building a bit of a head of steam.
Alex Stumpf
We were seeing him use his slider more, the sinker a little more.
Alex Stumpf
It's like, okay, that's a combo that can work.
Alex Stumpf
Whenever he was at his best last year, he was throwing his slider over 50% of the time.
Alex Stumpf
He really hasn't done that this year.
Alex Stumpf
We're finally seeing the four-seam usage dip down a little bit.
Alex Stumpf
Slider usage goes up.
Alex Stumpf
Sinker, he's basically thrown as much as the four-seamer this month.
Alex Stumpf
It's like, okay, this is a little different.
Alex Stumpf
I don't know if this is the right mix.
Alex Stumpf
I don't know if he's executing properly as is, even if he had the right mix.
Alex Stumpf
But, man, I'm just looking for something at this point.
Alex Stumpf
Because the Dennis Santana we saw last year, he was their best relief pitcher.
Alex Stumpf
And I'm convinced the Pirates would not have made the David Bednar trade last year if they didn't think, okay, we have someone internally who could pitch the ninth.
Alex Stumpf
And Dennis Santana took over those ninth-inning closer duties the last two months of the year.
Alex Stumpf
And outside of Colorado, looked pretty good.
Alex Stumpf
Then this winter, I thought, okay, he might be the closer.
Alex Stumpf
And then they signed Gregory Soto.
Alex Stumpf
It becomes like a, maybe he, it's a roaming closer.
Alex Stumpf
bullpen by committee.
Alex Stumpf
Play the matchups.
Alex Stumpf
And that's what we saw the first month.
Alex Stumpf
And for the first month, he looked like 2025 Dennis Santana.
Alex Stumpf
Then the Cardinals came to town at the end of April.
Alex Stumpf
And he just has not been the same guy since.
Alex Stumpf
Last year, 179 batting average allowed.
Alex Stumpf
This year, 244.
Alex Stumpf
Slugging percentage goes from 297 to 455.
Alex Stumpf
And you can look at, well, wait a minute, the exit velos are about the same.
Alex Stumpf
he's, the whiff rate is about the same.
Alex Stumpf
Why is it such a drastic drop-off?
Alex Stumpf
And yeah, to address the elephant in the room, he outperformed his peripherals in 2025.
Alex Stumpf
But by a pretty significant amount.
Alex Stumpf
217 ERA, an expected ERA of 351, according to Baseball Savant.
Alex Stumpf
Now, at the end of the day, a 351 ERA for someone you claimed off waivers, that's a fine pickup.
Alex Stumpf
If Dennis Santana had a 351 ERA right now, he would probably still have the ninth inning.
Alex Stumpf
But his balloon to 580, the expected ERA is five, so you can't even be like, oh, he's just unlucky, really.
Alex Stumpf
Like, he is not pitched well.
Alex Stumpf
And looking at it, the biggest change I see, he's not in the zone.
Alex Stumpf
Last year, 54.9% of his pitches were in the strike zone.
Alex Stumpf
This year, it's 44.1%.
Alex Stumpf
And you can see the walk rate, it's gone from 6.3 to 11.7, nearly doubled.
Alex Stumpf
And that's a big part of this equation.
Alex Stumpf
But I also look at the slider.
Alex Stumpf
And it has the same whiff rate as last year.
Alex Stumpf
It has the same expected slugging percentage.
Alex Stumpf
But the exit velo has gone from 86.2 miles per hour to 91.6.
Alex Stumpf
I think that is still his best pitch.
Alex Stumpf
I think it's still the pitch that he can throw the most and try to craft something out of it.
Alex Stumpf
But this last homestand, I saw a lot of belt-high sliders.
Alex Stumpf
He had an 0-2 pitch to Brice Turang, who nearly took one out.
Alex Stumpf
Like, it's a problem.
Alex Stumpf
So it's, his best pitch isn't getting soft contact.
Alex Stumpf
He's never been a huge whiff strikeout guy.
Alex Stumpf
He's always relied on getting some quick contact occasionally.
Alex Stumpf
Whenever he does it's usually soft or right at a fielder or something like that.
Alex Stumpf
But whenever you add the walks on top of everything, that's a big part of this equation.
Alex Stumpf
Not only are these at-bats going longer and he's facing more batters this way, he's putting on more base runners.
Alex Stumpf
So he could allow a gap shot last year and if the bases are empty, okay, you just got to pitch around the runner on second.
Alex Stumpf
This year, there's a runner on first, he scores, and now you have to pitch around the runner on second.
Alex Stumpf
The inning is already snowballing.
Alex Stumpf
We're going to take a quick break.
Alex Stumpf
We'll be right back.

Alex Stumpf
So is there a path out?
Alex Stumpf
So is there a path out?
Alex Stumpf
Maybe?
Alex Stumpf
I did notice this year, every month, Dennis Santana's arm angle has been going down.
Alex Stumpf
Now that could be a deliberate choice.
Alex Stumpf
That could be just a product of new mechanics.
Alex Stumpf
Maybe it's something that is subconscious.
Alex Stumpf
I don't think it would have gotten this far without it at least brought to his attention at this point.
Alex Stumpf
That the arm angle keeps going down.
Alex Stumpf
And it's only a handful of degrees at the end of the day, but it's still enough that it's like, look, if these pitches are performing like we have seen in the past, you have to look at where your arm slot is too.
Alex Stumpf
That could be part of this equation.
Alex Stumpf
I think throwing more sliders is part of this equation too.
Alex Stumpf
I think leaning into the sinker could be.
Alex Stumpf
I wouldn't mind seeing more cutters.
Alex Stumpf
That was 2024 Dennis Santana.
Alex Stumpf
Whenever he came in.
Alex Stumpf
And he had, a pretty good slider in these fastballs and he had no intermediary pitch.
Alex Stumpf
Say that five times fast.
Alex Stumpf
To bridge the gap.
Alex Stumpf
And that cutter became an interesting tool.
Alex Stumpf
I don't think it was a great tool for missing bats, but like that rebooting of Dennis Santana in 24, whenever they claimed him off waivers and it was like, let's see if there's anything here.
Alex Stumpf
That was their kick the tires pitch and it worked.
Alex Stumpf
And then we saw it less than 25 and he had a really good year in 25.
Alex Stumpf
So I don't think it's necessary.
Alex Stumpf
Like he doesn't absolutely need it to be successful, but we have seen him once lead into this pitch whenever he's struggling here and it worked out.
Alex Stumpf
I wouldn't mind seeing that, try out again.
Alex Stumpf
I really don't have a lot of faith with the four seamer at the moment.
Alex Stumpf
It's just not landing in the zone enough and I think that puts extra pressure to put the slider in the zone and we have seen a couple sliders really get left right up the middle and that's why they get hit harder.
Alex Stumpf
The number one thing for Dennis Santana is he needs to get in the strike zone more.
Alex Stumpf
I really think that is the path here.
Alex Stumpf
He has to right the ship mechanically, whether that's finding a way to fall closer to the mound instead of, towards first base, whether that's getting the arm slot in the right spot.
Alex Stumpf
I really don't know.
Alex Stumpf
I really don't know.
Alex Stumpf
I'm not at the end of the day, a major league pitching coach.
Alex Stumpf
I just throw out ideas and this is one where it's throw stuff up against the wall and see what sticks.
Alex Stumpf
But I don't know how much runway he has for that.
Alex Stumpf
Because while I didn't think that they were going to cut Dennis Santana whenever they brought up Thomas Harrington for a day or two.
Alex Stumpf
If they do make a couple additions to this bullpen.
Alex Stumpf
You have to wonder if his spot is going to be one of the ones on the chopping block.
Alex Stumpf
Carry eight relievers.
Alex Stumpf
Carmen Mijinsky is in the spot where whenever he's active or available, he'll have one of them.
Alex Stumpf
Yohan Santana.
Alex Stumpf
I know it's been messy and it's been some ups and downs, but he's actually had a really good month and change.
