Pinto was optioned to Triple-A Durham after Wednesday's 3-0 win over the A's, Marc Topkin of the Tampa Bay Times reports.
Pinto appeared in five games since being recalled from Durham on April 22, and he went 3-for-15 with a home run and two RBI. Francisco Mejia (illness) is expected to be activated from the COVID-19 injured list Thursday and resume his role as Tampa Bay's No. 2 catcher.
