Athletics Announce Several Roster Moves
The A’s announced a broad slate of roster moves Tuesday. In addition to their previously reported selection of Henry Bolte‘s contract from Triple-A, they’ve also selected Michael Stefanic‘s contract and placed shortstop Jacob Wilson on the 10-day injured list due to a left shoulder subluxation. Infielder Brett Harris was optioned to Triple-A as well, while minor league righty Eduarniel Núñez was designated for assignment. Additionally, the A’s noted that catcher Austin Wynns, whom they’d previously designated for assignment, cleared waivers and was released.
As covered this week, Bolte has been the hottest-hitting prospect in the minors. He’s a plus runner with developing pop who recently rattled off hits in an astonishing 12 consecutive plate appearances to boost his batting line to a mammoth .348/.418/.658. He’s popped a dozen homers, swiped 17 bags and should get plenty of run in center field with Denzel Clarke still on the shelf. Zack Gelof has been seeing a good bit of action in center, but the former second baseman will probably head back to the infield with both Wilson — whose known shoulder injury now has a formal designation — and Max Muncy on the injured list.
With two infielders shelved, the A’s will turn to Stefanic, who’ll be making his team debut. The longtime Angels farmhand has seen prior action in parts of four major league seasons. He’s mustered only a .227/.314/.267 slash in 289 big league plate appearances, but the 30-year-old Stefanic is a prolific Triple-A hitter. He’s played parts of six seasons at the top minor league level and touts a .326/.422/.447 batting line with a tiny 9.5% strikeout rate. Stefanic has marginal power, bottom-of-the-scale sprint speed and below-average defensive skills, but scouting reports from Baseball America, FanGraphs and MLB.com have placed 70 and 80 grades (on the 20-80 scale) on his pure hit tool over the years.
Núñez, 26, was one of four players the A’s acquired in last year’s blockbuster sending Mason Miller and JP Sears to the Padres. That package was headlined by top prospect Leo De Vries and also included a pair of quality rotation prospects in Braden Nett and Henry Baez. Núñez was the clear “fourth” prospect in the deal. The hope was that he could quickly reach the majors and give the A’s a power arm to plug into their bullpen, given that he’d already had a brief MLB call-up in San Diego and was enjoying success in Triple-A at the time of the swap.
In a way, that proved true. Núñez made his A’s debut just two days after the trade deadline last summer, but he struggled out of the gate. He pitched eight innings with the Athletics and was tagged for eight runs on nine hits, seven walks and a pair of hit batters. Núñez did fan nine batters, but when accounting for all the walks and the pair of batters he plunked, those nine punchouts only represented 23% of the opponents he faced.
Lackluster debut notwithstanding, the A’s surely had some hope that Núñez could turn things around in 2026. That hasn’t happened. Núñez has a respectable 4.61 ERA through 13 2/3 innings (2 1/3 in Double-A, 11 1/3 in Triple-A), but he’s walked 11 of his 67 opponents (16.4%) and plunked another two batters (3%). Since coming to the A’s organization last summer, Núñez has faced 155 batters between the majors and minors. A whopping 19.3% of them have reached base without putting a ball in play, whether by walk or hit-by-pitch. He’s also tossed six wild pitches in a total of 33 1/3 innings.
As concerning as the poor command — if not more concerning — is the precipitous velocity drop Núñez has experienced this season. He sat 98.1 mph on his four-seamer last year but is at an even 95 mph so far in 2026. Last year’s slider sat 88.5 mph. This year, it’s at 87 mph.
There’s no known injury for Núñez. He hasn’t been on the injured list and most recently pitched only two days ago. However, between the velocity drop and the poor command, the A’s probably feel there’s a chance they can pass him through waivers and hang onto him as non-roster depth. That may well be the case, but Núñez is a 26-year-old with a decent track record in the upper minors and a pair of minor league option years remaining. If he’s healthy and another club feels the velocity drop and/or command are fixable with some mechanical adjustments, it’s at least possible he’ll be claimed or flipped to another club in a small trade.
The A’s will have five days to trade Núñez or place him on outright waivers. The waiver process would take another 48 hours, so his DFA will be resolved within a maximum of one week.
A’s To Promote Henry Bolte
The Athletics are calling up outfield prospect Henry Bolte, as first reported by Terrel Emerson. He’s not on the 40-man roster, but the A’s have a vacancy there, so they’ll only need to make a corresponding 26-man roster move when they formally select Bolte’s contract.
A 2022 second-round pick, Bolte is the hottest-hitting prospect in baseball at the moment. He recently rattled off hits in 12 consecutive plate appearances (video link) and is sitting on a .348/.418/.658 batting line (157 wRC+) with a dozen homers, seven doubles, three triples, 17 steals (in 19 tries), a 9.6% walk rate and a 22% strikeout rate in 177 Triple-A plate appearances. He’s averaging 90.4 mph off the bat to go along with a strong 43% hard-hit rate.
The A’s young outfield has impressed in recent seasons, but both Tyler Soderstrom and Lawrence Butler have fallen short of expectations thus far. Soderstrom is hitting .207/.293/.407. Butler is at just .179/.278/.282 on the season. Both players have been plagued by BABIP marks that are about 60 points shy of league average despite quality batted-ball profiles. Soderstrom and Butler are both averaging better than 90 mph off the bat with a hard-hit rate just over 48%. They’re also both walking in at least 11% of their plate appearances. Both stand as candidates for positive regression based on the strength of their contact.
Soderstrom and Butler typically man the outfield corners. However, center fielder Denzel Clarke has been out of action for a few weeks due to a bone bruise in his left foot, which has given Butler some time in center. The A’s have also given former second baseman Zack Gelof some run in center, and he’s hit well in the new role, batting .274/.328/.484 in a small sample of 69 plate appearances. His batted-ball fortune is on the other end of the spectrum, about 50 points higher than league average, at .341. In all likelihood, his slash stats will come down a bit, but Gelof is still enjoying his most productive stretch since 2023.
It’s not fully clear how the outfield mix will be tweaked to accommodate Bolte. He’s played primarily center field. The A’s aren’t calling him up to sit on the bench in a backup role, so it seems like Bolte will handle center field regularly. Soderstrom and Butler could play full-time corner roles, with Gelof perhaps mixing in across all three spots in addition to work at second base and third base. It might be natural to think he could platoon in right field with the lefty-swinging Butler, who’s just a career .221/.262/.378 hitter versus lefties, but the righty-swinging Gelof has been even worse against lefties in his own career: .157/.238/.252. The A’s do have some infield injuries at the moment, with Max Muncy on the IL and Jacob Wilson possibly joining him there.
However it shakes out, Bolte is likely going to play every day. He’s ranked fifth among A’s prospects at MLB.com, seventh at Baseball America and tenth at FanGraphs. Bolte topped the latest Prospect Hot Sheet at Baseball America, where J.J. Cooper noted that he’s still a bit too prone to getting beaten in the zone but has developing power and can absolutely punish in-zone mistakes.
There’s not enough time left in the season for Bolte to accrue a full year of major league service, so even if he sticks from here on out, he’ll be controllable six more years beyond the current season. The May timing of his promotion means he’ll qualify as a Super Two player if he stays up for good, making him eligible for arbitration four times rather than the standard three. Then again, if Bolte hits the ground running, the A’s could always look to render that Super Two trajectory moot by signing him long term, as they’ve done with Soderstrom, Butler, shortstop Jacob Wilson and designated hitter Brent Rooker over the past couple years.
Draft Signings: Phillies, Red Sox, Yankees, Astros, A’s, Blue Jays
We’ll use this post to round up some of the more notable recent draft signings:
- The Phillies announced they’ve signed #17 overall pick Justin Crawford. Jim Callis of MLB.com reports (Twitter link) that the lefty-hitting outfielder will receive a $3.8948MM signing bonus, a hair above the pick’s slot value. Crawford, the son of four-time All-Star Carl Crawford, was ranked by Baseball America as the #18 prospect in the class. A product of a Nevada high school, Crawford is an excellent runner who’s regarded as a possible plus defender in center field. The 6’3″ outfielder is seen as a hit-over-power offensive player. He’d been committed to LSU.
- The Red Sox agreed to a deal with #24 selection Mikey Romero, as first reported by Chad Jennings of the Athletic (on Twitter). It’s a $2.3MM deal to convince the infielder to bypass a commitment to LSU. A left-handed hitter from a California high school, Romero was ranked the #54 prospect in the class by BA, explaining why his deal comes in a fair bit shy of the pick’s $2.98MM slot value. BA praises his bat-to-ball skills but notes that his slender frame leads to below-average raw power.
- The Yankees announced agreement with #25 pick Spencer Jones. Callis reports (Twitter link) that he’ll sign for slot value at $2.8808MM. The class’s #49 prospect according to Baseball America, Jones is a 6’7″ outfielder from Vanderbilt. The left-hander posted a massive .370/.460/.644 showing with 12 home runs and 14 stolen bases through 272 plate appearances during his final season with the Commodores. Jones stuck out at a lofty 23.5% rate, an unsurprising development for a player of his size, but his combination of power and athleticism got him into the late first round.
- Astros first-round pick Drew Gilbert has signed, according to a club announcement. Callis reports (Twitter link) he’s landed a $2.5MM bonus, a little under the $2.62MM value of the 28th overall pick. A left-handed hitting center fielder from the University of Tennessee, Gilbert was the #24 prospect in the class, per BA. The 5’9″ outfielder has a well-rounded offensive skillset and a good chance to stick in center field, and he’s coming off a .362/.455/.673 showing with more walks than strikeouts in a breakout junior season for the Vols.
- The A’s are in agreement on an overslot deal with 2nd-round pick Henry Bolte, Callis reports (on Twitter). He’ll receive a $2MM bonus to sway him out of a commitment to Texas. A 6’3″ outfielder from the Bay Area, Bolte entered the draft as the #42 prospect in Baseball America’s estimation. He’s regarded as one of the higher-upside players in the class, showing an enviable combination of power, speed and center defense. However, the right-handed hitter also comes with question marks about the high amount of swing-and-miss in his game.
- The Blue Jays went overslot with a $2MM bonus for supplemental second-round pick Tucker Toman, Callis reports (on Twitter). That’s more than double the $846,900 slot value associated with the #77 overall selection. That reflects a loftier prospect status, as the 18-year-old infielder from a South Carolina high school had been the #40 player in the class, according to BA. A 6’1″ infielder, Toman is a switch-hitter with a chance for a strong hit/power combination, although it’s questionable whether he can stay on the dirt or will eventually have to move to the corner outfield. Like Crawford and Romero, he’ll forego a commitment to LSU and start his pro career.
