TORONTO -- Baltimore Orioles right-hander Grayson Rodriguez was scratched from Tuesday's start at Toronto minutes before the first pitch and replaced by right-handed reliever Albert Suárez.

The Orioles did not give a reason for the move. Rodriguez was on the injured list from April 30-May 18 because of right shoulder inflammation.

Rodriguez, 24, is 13-4 with a 3.86 ERA in 20 starts for the AL East-leading Orioles, tied with Atlanta's Chris Sale and Kansas City's Seth Lugo for the major league lead in victories.

Baltimore's first-round pick in the 2018 draft, Rodriguez has won five of his last six decisions. He went 7-4 with a 4.35 ERA in 23 starts as a rookie last season.
