The Blue Jays optioned Estrada to Triple-A Buffalo on Monday, Ben Nicholson-Smith of Sportsnet.ca reports.
Estrada had pitched each of the last three days, so his spot on the roster will be filled by a fresh bullpen arm. The 27-year-old has permitted seven runs (six earned) with an 8:8 K:BB over 12 innings during his time with the big club in 2026.
