While the Blue Jays have one of the most stocked farm systems in all of baseball, don't expect them to make a splash when it comes to September call-ups. Most, if not all of Toronto's major league ready prospects are already in the show.
Twenty-four year old right fielder Eric Thames has been up since May, while pitchers Henderson Alvarez and Joel Carreno got the call in August. Same goes for third baseman Brett Lawrie, who has been on a tear since his promotion, and catcher Brian Jeroloman, who despite joining the team following the Hill and MacDonald for Johnson deal, has yet to see any game action.
Expect the initial group of Blue Jays September call-ups to include mainly players with at least some prior major league experience.
Even though prospects like Adeiny Hechavarria and newly crowned Eastern League MVP Travis d'Arnaud have been getting a tremendous amount of attention as of late, they'll be helping the organization in another way during the early part of September―the Blue Jays double-A affiliate, the New Hampshire Fisher Cats, have all but clinched a playoff spot and are expected to make a run at the league championship.
Alex Anthopoulos has previously stated that Hechavarria would benefit greatly from returning to AA following the completion of the AAA season in order to get a taste of post-season baseball.
For d'Arnaud, the Jays would be remiss to take the team's leader with the playoffs right around the corner. The latest possible date for the completion of the Eastern League playoffs is September 17.
That would leave only a week and a half of games for Hechavarria and d'Arnaud to get their first taste of the big leagues. Although unlikely, I wouldn't be surprised to see those two get a handful of at-bats over the season's final 10 games or so.
But until then, Toronto appears set to call up a quartet of players who have already seen the majors at some point in their careers. Among them are an impressive career turnaround, an amazing comeback story, a "can't miss prospect" who has been off-target this season, and a young player who has yet to prove that his gaudy AAA numbers can translate to the majors.
