Knapp signed a minor-league contract with the Rangers on Wednesday that includes an invitation to spring training.
Knapp spent all of the 2023 season at the Triple-A level between the Tigers and Astros organizations, posting a .705 OPS with nine homers. He's slashed .209/.310/.313 over parts of six seasons in the majors and will compete for the right to back up Jonah Heim at catcher.
