The Toronto Blue Jays have placed pitcher Marco Estrada on the 10-day disabled list, retroactive July 10 with a left glute strain.
Outfielder Dwight Smith Jr. has been recalled from Buffalo (AAA) and is active for tonight's game against the Boston Red Sox.
The 34-year-old left Tuesday's home game against the New York Mets after recording just one out in the first inning. An MRI revealed the strain after the game.
Estrada said he had been dealing with the issue since the day after his road start against the L.A. Angels on June 22 and felt it again in his next start in Houston a week later.
Estrada is 4-7 with a 4.72 earned-run average through 17 starts this season.
Meanwhile Smith has played 15 games so far this season with the big league club batting .300 with 1 home run and four RBI.
