The Red Sox optioned Burgos to Triple-A Worcester on Sunday, Mac Cerullo of the Boston Herald reports.
The Red Sox will swap Burgos out for a fresh bullpen arm in Seth Martinez, whose contract was selected from Triple-A in a corresponding move. After getting called up Friday, Burgos made three-inning relief appearances on consecutive days, giving up two earned runs on two hits and no walks while striking out four and earning his first MLB save.
