Rajai Davis' season is over for the Toronto Blue Jays.
Manager John Farrell told reporters on Tuesday that the speedy outfielder has suffered a setback in his recovery from a hamstring injury while on a rehab assignment down in Florida.
As a result, with less than a month remaining in the regular season, Farrell said it made sense for the American League team to shut him down for the rest of the season.
Davis, acquired from the Oakland A's in November, provided Toronto with some much needed speed on the roster this season, swiping 34 bases in 94 games.
But Davis was also thrown out 11 times and his just .238 with a .273 on-base percentage.
The Blue Jays also has announced the promotion of six more players to the Major League roster for the stretch run, led by pitcher Kyle Drabek.
Drabek, the centrepiece in the Roy Halladay trade, started the season in the Blue Jays starting rotation but got off to a horrible start and was soon optioned back to the minors.
Other pitchers who will join Drabek in Toronto will be Brad Mills, Chad Beck and Danny Farquhar.
Toronto manager John Farrell said all the newcomers will be utilized out of the bullpen.
The Blue Jays have also added outfielder Adam Loewen, a native of Surrey, B.C., and first baseman David Cooper to the roster.
The players are expected to be in uniform in time for Wednesday's game.
