Ronald Acuña Jr. has entered the kind of slump that stops conversations in a clubhouse: 1-for-16 since May 22 and, over the weekend, four strikeouts in one game and a broken bat on a slow grounder where he didn’t hustle to first.
The week only magnified the problem. Acuña struck out four times Saturday against the Nationals and, the next day, snapped his bat on a soft grounder and failed to run it out. He has a.240 average this season with two home runs and nine doubles, 22 runs, 12 RBI, seven steals and a.704 OPS. Buck Belue, watching the struggles, put it bluntly: "He’s getting beat by the fastball… I never thought I’d see this."
There were flashes. On Tuesday in Atlanta’s 7-6 win over the Red Sox, Acuña had an RBI single. But the next night the Braves were blanked, 8-0, and Acuña and Austin Riley combined to go 0 for 6 with two walks. In that loss Acuña walked to open the game and then stole second, later settling for a line-drive out to right field. The regular-season series with Boston was evened at 1-1, and Atlanta remained 37-19 with an eight-game lead in the NL East.
Defense and reaction time have also become talking points. "Acuna isn’t getting very good jumps in the outfield," Billy Heyen said, a blunt assessment echoed by the metrics: Baseball Savant ranks Acuña with the seventh-worst jump on fly balls in the majors and measured him as losing about 1.5 feet relative to average on reaction time. That same database lists his walk percentage at 87, bat speed at 92 and baserunning value at 78, but notes his average exit velocity and xBA are down.
The contrast between the numbers and Acuña’s reputation deepens the tension. He is a five-time All-Star and a former National League MVP, and the Braves still own the best record in the NL. Yet his power output — two homers and nine doubles — and the 1-for-16 slide since May 22 are concrete signs the player who drives Atlanta’s lineup is not performing to standard. The primary on-field clues — repeated strikeouts, diminished jumps in center field and slower reaction — line up with what teammates and observers are seeing.
There are possible explanations that remain unresolved. Reports indicate Acuña could still be battling a hamstring issue, which would help explain reduced range and slower first-step reactions, but the club’s decisions about playing time, rest or mechanical adjustments have not been spelled out. He did show baserunning aggressiveness by stealing second after a walk Wednesday, which suggests some tools remain intact even as contact and timing falter.
The single most consequential unanswered question is now clear: will the Braves alter Acuña’s workload or approach to arrest the slide before his free agency after 2027? With a 37-19 record and room at the top of the division, Atlanta can afford a measured response — but the longer a star this central to the lineup remains in this slump, the harder it will be to trust the same version of Acuña that produced MVP-caliber seasons.
