Pitcher needs time to rest sore shoulder
It was Halladay's first time on the DL. The move was retroactive to May 28 and Toronto recalled right-hander Bob File from Triple-A Syracuse.
Halladay missed his scheduled start in Seattle on Tuesday after feeling discomfort before the game. He was scratched and left-handed reliever Jason Kershner took his place.
Kershner will again pitch in Halladay's place Sunday.
Halladay is eligible to return June 11 when Toronto plays Arizona. The Blue Jays hope he will be able to start the following day.
Halladay is 5-4 with a 3.58 ERA. He was a durable last year, going 22-7 with a 3.25 ERA and leading the majors with 266 innings.
Halladay made 36 starts last year and tied for the AL lead with nine complete games.
File was 1-0 with four saves and a 0.51 ERA in 11 games for Syracuse this year.
