A’s Likely To Rely On Internal Options At Third Base

The A’s added to their infield with this week’s acquisition of Jeff McNeil from the Mets. The A’s sent a lottery ticket pitching prospect (Yordan Rodriguez) while taking on $10MM of the $17.75MM remaining on the veteran’s contract.

Adding help at one of second or third base had been on the A’s checklist since the beginning of the offseason. It seems they’re content with one outside pickup. General manager David Forst told Martín Gallegos of MLB.com that the A’s view McNeil as their primary second baseman. They’re planning to leave the third base job open for a Spring Training competition among a few players already on the roster.

“We’ll probably look internally at third base,” Forst told Gallegos. “Max Muncy did a really nice job there in his limited time. Darell Hernaiz has shown he can play the position. Brett Harris has a lot of experience at third base. So I like our internal options.” Forst didn’t specifically mention Zack Gelof, who is questionable for the start of exhibition play as he works back from September shoulder surgery. Gelof was a college third baseman but hasn’t played anywhere other than second since he reached Triple-A at the end of the 2022 season.

None of Muncy, Harris or Hernaiz showed a lot in limited big league playing time. Harris was the best of the group offensively, hitting .274 with a .349 on-base percentage. That came in just 84 plate appearances, and he was a .146/.276/.262 hitter in a similar amount of playing time as a rookie the year before. Muncy struck out in 31% of his first 220 trips to the plate in the big leagues, leading to a .214/.259/.379 slash. Hernaiz made a ton of contact with below-average exit velocities. He only managed two homers and a .231/.292/.306 line over 197 trips to the plate. Gelof showed some promise when he hit 14 homers in 69 games as a rookie in 2023. He led the American League in strikeouts in his first full season and battled injuries for most of the ’25 campaign, dropping him down the depth chart.

It’s one of the weakest third base groups in MLB on paper. 19-year-old top prospect Leo De Vries is likely to open the season in Double-A. It’s not out of the question that he forces his way to the big leagues before the end of the year, especially if the A’s hang around the playoff bubble. That won’t be a consideration out of the gate, so the A’s will need someone from their group of upper level infielders to take a step forward.

If the A’s wanted to go outside the organization, they could probably get a veteran like Yoán Moncada or Ramón Urías on a cheap one-year deal closer to Spring Training. That doesn’t appear to be the current plan. The McNeil acquisition pushed their projected payroll to $87MM, as calculated by RosterResource. That’s $12MM above where they opened the ’25 season. They’ve yet to make any moves to upgrade a rotation which was 27th in ERA and 25th in strikeout percentage. Forst reiterated to Gallegos that acquiring a starter is the “first focus right now.”
