Ort was optioned to Triple-A Worcester on Tuesday, Chris Cotillo of The Springfield Republican reports.
The right-hander joined the Red Sox last Friday, but he did not make an appearance during his four games with the club. Martin Perez's (illness) return from the COVID-19 IL pushes him back to Worcester for the time being, but he could rejoin the big-league roster should Boston need to add an arm during the final three weeks of the regular season.
