The Athletics selected Stefanic's contract from Triple-A Las Vegas on Friday.

4w agoRotowire

Stefanic has spent the majority of the 2026 season with Las Vegas, where he's slashed .296/.405/.414 with six homers, 59 RBI, 59 runs scored, nine stolen bases and a 59:43 BB:K across 453 plate appearances in the Triple-A club's hitter-friendly confines. He'll serve as infield depth with the big club.

Stefanic re-signed Wednesday with the Athletics on a minor-league contract.

May 21Rotowire

The Athletics designated Stefanic for assignment over the weekend, and upon clearing waivers, the 30-year-old infielder elected free agency. He was on the open market for just two days before opting to return to the Athletics organization and agreeing to report to Triple-A Las Vegas. Before being dropped from the 40-man roster, Stefanic saw action in two games for the Athletics and went 2-for-5 with a run.

Stefanic was sent outright to Triple-A Las Vegas on Monday, Jason Burke of SI.com reports.

May 19Rotowire

Stefanic was booted from the 40-man roster Saturday, and after going unclaimed on waivers, he'll head to Triple-A. The 30-year-old appeared in two games for the A's and went 2-for-5 with one run scored during his brief time with the big-league club.

The Athletics designated Stefanic for assignment Saturday.

May 16Rotowire

Stefanic will be pushed off the Athletics' 26- and 40-man rosters following the team's acquisition of Alika Williams from Pittsburgh on Saturday. Stefanic went 2-for-5 with a run scored during his four-day stint in the majors and owns a .706 OPS through 149 plate appearances at Triple-A Las Vegas. He'll likely spend the rest of the season as organizational depth if he clears waivers.

The Athletics selected Stefanic's contract from Triple-A Las Vegas on Tuesday.

May 12Rotowire

The 30-year-old will get a look in the big leagues with the A's after signing as a non-roster invitee in December and failing to make the Opening Day roster. Stefanic's .250/.351/.355 slash line in 149 plate appearances at Triple-A this year is underwhelming, though he does have a 17:16 BB:K. He'll provide the club with some infield depth as Jacob Wilson (shoulder) heads to the injured list.
