Zavala exercises an upward mobility clause; essentially placing him on waivers and if anyone was willing to add him to the 40-man roster, he would head to that team. No one made that claim, so Zavala will be org depth in Triple-A.

Zavala fortifies Boston’s catching depth behind Connor Wong. He makes sense as a temporary stopgap until top prospect Kyle Teel is ready to ascend to the big leagues at some point next year. The 31-year-old journeyman backstop holds a lifetime .613 OPS in 194 contests in the majors since 2019.

Zavala was designated for assignment on Friday but went unclaimed, so he will remain with the Mariners as veteran catching depth. He hit .154/.214/.282 in 18 games for Seattle this season.

Zavala didn’t play this time around in his three days with the Mariners. He’s hit .154/.214/.282 in 18 games for Seattle this season.
