Manager John Farrell said Romero will skip his scheduled start Saturday at Boston and will work on nine days rest Sept. 12 against Seattle. Beginning with that start, Toronto will use a six-man rotation for the remainder of the season, with Aaron Laffey joining Romero, Brandon Morrow, Henderson Alvarez, J.A. Happ and Carlos Villanueva.
A first time All Star in 2011, Romero allowed seven runs in one-plus inning against Tampa Bay last Sunday in the shortest outing of his career. Winless since June 22 at Miami, he's 8-13 overall and his ERA of 5.85 is the highest among qualified AL starters.
