Luke Weaver Has Become A Bullpen Name Pirates Fans Need To Know

Discover how Luke Weaver's unconventional pre-game ritual may be the secret behind his impressive performance on the mound with the Pittsburgh Pirates.

PITTSBURGH - Luke Weaver has found a very simple way to keep himself going: orange juice.

That’s not a throwaway line, either. The Pirates’ new high-leverage reliever says he reaches for it four or five times a day, and he’s not shy about why.

“I think it's delicious,” Weaver told MLB.com minutes before grabbing a fresh plastic cup of OJ. “I think it's helpful.

I think if you want to get nutritionally deep into it, it has a lot of benefits that keeps the mind and the body energized in different ways. And it just tastes freaking good.”

Pittsburgh brought Weaver in from the Mets at the Trade Deadline, sending No. 10 prospect Sammy Stafura the other way in hopes of stabilizing a bullpen that needed help. So far, the move has done exactly what the Pirates wanted.

Weaver has posted a 2.30 ERA and a 0.89 WHIP this year, even with three earned runs allowed on Aug. 15.

The 32-year-old has added more than numbers to the mix. He arrived with World Series experience, a positive presence and a personality that shows up quickly. Orange juice, naturally, has become part of the package.

“I’m probably drinking it four or five times a day. It's just pick-me-ups,” Weaver said.

“I drink coffee, but it’s just a little bit of a healthier, easier way to establish and keep the energy mainstream. Easy carbs … I mean, we could sit for an hour and talk about it.”

The OJ obsession traces back to a joke that stuck. In 2024, as Weaver was establishing himself as the Yankees’ closer, the YES Network asked what had caused a jump in velocity. Instead of leaning on the usual baseball clichés, he credited orange juice.

Two years later, Weaver says he likes keeping that side of himself visible. He doesn’t want interviews to sound too “robotic,” and he wants fans to get a sense of who he is. But the orange juice line wasn’t just for laughs.

According to “Healthline,” orange juice is rich in vitamin C, folate and potassium, and studies have shown that long-term orange juice consumption lowered levels of both total and “bad” LDL cholesterol. Weaver said he prefers organic juice, though he’s fine with pulp or no-pulp.

“I've just kind of kept that lighthearted joke,” Weaver said. “But I do drink a lot of orange juice.”

On the field, the juice seems to be working. Weaver comes in with energy to spare, often sprinting from the bullpen to the edge of the infield for his umpire check-in.

His road to Pittsburgh began a decade ago in St. Louis, where he broke in as a starter and remained in rotations through stops in Arizona and Cincinnati, while also working out of the bullpen in Kansas City and Seattle.

Then came his chance in relief with the Yankees in 2024.

That year, Weaver helped New York reach the AL pennant, throwing 84 innings with a 2.89 ERA. He saved four games in the regular season, then sharpened further in October, finishing the postseason with four saves and a 1.76 ERA.

Mason Montgomery said Weaver and veteran Kirby Yates carry an “aura” because of what they’ve done in big spots. Weaver, though, says the pressure never really disappears. The game can slow down, but the challenges don’t.

His current stretch has looked different than the one that defined him in New York. Pittsburgh overhauled its bullpen at the Deadline, and with the offense only recently finding more life, Weaver still hasn’t had a save chance.

He was 50/50 on whether he’d be moved, wanted to remain in New York, and was among the Mets players told to stay back in New York on Aug. 3 instead of traveling to Cleveland. He was dealt to the Pirates midday before the Deadline and pitched just once in his first 10 days with the club.

“It’s not easy. It’s not something you prepare for.

It’s not something that anybody’s got a recipe for. I’m learning as I go.

This whole month has been a bit of a blur,” Weaver said.

For now, the Pirates expect him to work mostly in the eighth or ninth innings alongside Montgomery. And if Weaver keeps bringing the same energy to those spots, the orange juice routine isn’t going anywhere.

Pirates Make A Quiet Catching Move That Could Suddenly Matter

The Pirates added some catching depth on the quiet Monday by bringing in veteran Christian Bethancourt from the Yankees. For a club always trying to patch together enough coverage behind the plate, it is the sort of low-profile move that can matter more than it first looks, especially when the season starts to squeeze a roster.

Bethancourt had been in Triple-A with New York this season and last appeared in the majors in 2024, so Pittsburgh is banking on experience and organizational depth more than flash. The deal did not come with much fanfare, which fits the profile of a move like this, but the Pirates clearly saw a need worth addressing before it became more urgent. [Read more 🡒]

Pirates Infield Shuffle Puts New Pressure On A Lineup Still Searching

With the Pirates still trying to piece together the right mix on offense, the latest lineup adjustment adds another layer to an infield that has been in motion for much of the season. Oneil Cruzs return and his two-run home run offered a reminder of how much the club still needs from the middle of the order, but Pittsburgh keeps juggling positions as it looks for a combination that can stabilize both the defense and the bats around him.

Nick Gonzales is the newest piece to move, taking over at second base after spending most of the season at third. Brandon Lowe is shifting into designated hitter duty while Jared Triolo stays at third and Jacob Gonzalez remains at shortstop, giving the Pirates a slightly different look as they manage injuries and performance. It is the kind of shuffle that can help in the short term, though it also underscores how much the lineup is still searching for something that lasts. [Read more 🡒]

Braxton Ashcraft Is Giving Pirates Fans Real Reason To Believe

Braxton Ashcraft keeps giving the Pirates something sturdy to build on. After a complete-game start in Miami, he followed it up by working eight efficient innings on 80 pitches in a 4-1 win over Detroit, extending a stretch that has made his August look a lot more like a pitcher settling in than one still trying to find his footing. His previous outing included 10 strikeouts, and over four starts this month his ERA has come down to 2.00.

What has stood out is not just the results, but the way he is getting them. Ashcraft has leaned heavily on his sinker while also showing a faster four-seam fastball, a mix that has played well when his execution is sharp and his competitiveness is front and center. Teammates and coaches have taken notice, and for a Pirates club that can always use another arm to trust, Ashcraft is starting to look like more than a nice short-term story. [Read more 🡒]
