MILWAUKEE - The Pirates went into the trade deadline looking for bullpen help, and they came away with another major arm.
Pittsburgh acquired Mets right-handed reliever Luke Weaver, according to Jorge Castillo of ESPN, adding a second bullpen piece by trade after bringing in right-hander Camilo Doval from the New York Yankees on Aug. 1.
The price was Sammy Stafura, Pittsburgh’s No. 9-ranked prospect per MLB Pipeline, who goes back to the Mets in the deal, according to The Athletic’s Will Sammon. Stafura originally came to the Pirates from the Cincinnati Reds in the trade for Ke’Bryan Hayes last season.
Across 60 games split between Low-A Bradenton and High-A Greensboro, Stafura hit .276/.367/.593 with 20 home runs.
Weaver arrives with the kind of track record Pittsburgh was clearly targeting: a reliable high-leverage reliever the club can trust the rest of the way as it chases a postseason spot. The Pirates had shown interest in him before, and now they’ve landed one of the better bullpen arms available at the deadline.
The 33-year-old has been excellent for the Mets this season, working 42 times over 44.2 innings and putting up a 1.84 ERA. He struck out 45 and walked 11, while holding opponents to a .162 batting average and posting a 0.82 WHIP.
His underlying numbers were just as strong. Weaver carried a 2.84 expected ERA and a .201 expected BAA, along with a 34.0% chase rate, 30.4% whiff rate, 26.6% strikeout rate, 6.5% walk rate and 34.2% barrel rate.
New York used him almost exclusively in the late innings, and he handled the pressure well. Weaver logged a 1.86 ERA in the seventh inning and a 2.22 ERA in the eighth, all while working in high-leverage spots.
He has done most of his damage with two pitches, his four-seam fastball and changeup, both of which carried a +6 run value on Statcast. He’ll also mix in a cutter.
Weaver has been effective against both sides of the plate, but especially tough on right-handers. Left-handed hitters have managed a .217/.278/.325 line against him for a .603 OPS, while right-handed hitters have been held to .099/.167/.155 for a .322 OPS.
This is Weaver’s 11th major league season, and he has appeared in 312 games. That kind of experience gives Pittsburgh another veteran option for the late innings, whether the Pirates decide to use him as a closer or keep him in a setup role.
He has no closer experience, so the Pirates may be cautious about immediately making that switch. Still, the path is there for Weaver to become their top high-leverage reliever, with Doval, left-handers Mason Montgomery and Gregory Soto, and others available for later-game work as well.
No matter where he ends up in the inning structure, Weaver gives the Pirates a much stronger bullpen and helps their push toward the postseason.

Pirates Just Made A Deadline Move Fans Will Want Explained
A deadline-day move quietly added another layer to the Pirates roster picture, with right-hander Hunter Stratton on the way out in a deal that sent him to San Diego. Pittsburghs return was right-hander Andrew Moore, and the transaction came just before the MLB trade deadline, a reminder that even smaller swaps can tell you plenty about how a front office is sorting out the margins of its pitching depth.
Stratton was then optioned to Triple-A, where hell give the Padres minor league pitching help, while San Diego opened a 40-man spot by moving Jason Adam to the 60-day injured list as he continues to recover from a shoulder injury. For the Pirates, the move fits the kind of low-profile deadline business that often gets overlooked in the rush for bigger names, but it also leaves a few questions about how they value the arms that remain in the system.

Henry Davis No Longer Feels Safe In Pittsburgh
The Pirates willingness to entertain trade talk around Henry Davis before the deadline says plenty about where things stand with the former top pick. Davis has had a rough major league stretch at the plate, and even though he has been part of the clubs catching picture, Pittsburghs openness to listening on him suggests his place in the organization is no longer as protected as it once was.
New York checked in on Davis, but the Yankees ultimately passed after deciding he was not the type of hitter they wanted. For Pittsburgh, the more revealing part is not the near-miss itself but the fact that Davis was even available for discussion, which adds another layer to an already unsettled picture for a player whose long-term fit with the team is now very much in question.

Pirates Just Lost A Huge Piece Of Their Rotation
The Pirates rotation took a major hit when the club announced Mitch Keller is dealing with a teres major muscle injury in his right shoulder. Keller had been trying to push through a rough stretch, and the injury helps explain a recent outing in Cincinnati that went sideways early and left him tagged for seven earned runs.
Now the bigger concern is availability, not form. Keller is not allowed to throw for six to eight weeks, which shuts the door on any realistic chance of getting him back before the season ends and leaves Pittsburgh to sort out the rest of its rotation without one of its most established arms.
