Aaron Sanchez reported improvement in his sore upper body Saturday, three days after he was skipped in the rotation, but the Toronto Blue Jays will give the 22-year-old a little more recovery time before throwing him back on the mound.

Sanchez was placed on the 15-day disabled list with a lat strain following Sunday's series finale at Fenway Park, manager John Gibbons told reporters.

Replaced on the mound Wednesday by Scott Copeland, Sanchez will also miss Tuesday's scheduled start at Citi Field, but his backdated stint will allow him to return as soon as June 21.

"It's just the right move, smart move, get rid of it," Gibbons said after the Blue Jays' 11th straight win Sunday.

Sanchez, who made 24 relief appearances for Toronto last summer, was thrust into the rotation this spring following a season-ending knee injury to Marcus Stroman. Though his tenure in the rotation started inauspiciously, Sanchez boasts a 3.35 ERA (109 ERA+) through 11 starts thus far despite issuing more walks than any other pitcher in the American League.
