Tellez signed a minor-league contract with Atlanta on Friday, Jon Heyman of the New York Post reports.
Tellez spent time with the Mariners and Rangers last season, slashing .228/.276/.443 across 312 total plate appearances. He's spent the entire offseason on the open market but still saw a little bit of action while playing for Mexico in the World Baseball Classic, during which he went 1-for-9 with two walks and two strikeouts across four games. The 31-year-old will almost certainly begin 2026 as an organizational depth piece at Triple-A Gwinnett, but he'd be likely to join the big club if Matt Olson were to miss any amount of time.
