The Toronto Blue Jays have made big changes after a 15-inning marathon that resulted in a 5-4 loss to the Oakland Athletics. The A’s walked off for a major league-best 13th time this year.

The Blue Jays have called up Adeiny Hechavarria from Triple-A Las Vegas, who will most likely play third base after Brett Lawrie left the game with what is said to be ribcage tightness.

Hechavarria had been tearing it up in the Pacific Coast League, batting a scorching .312/.363/.424 to go along with 63 RBI, 38 walks and a .961 fielding percentage. He is widely regarded as the best defensive player in the Jays system, and one of the best in the PCL.

It’ll be interesting to see how he performs in the bigs, as the PCL—and Las Vegas in particular—is widely known for being a hitter’s league. Hechavarria has a tendency to fall behind in the count, which might hinder his ability to get in a good hitter’s count. So facing A.J. Griffin will be a good test for him to start his MLB career. 

Nonetheless, Jays fans have been anxious to see how he performs with the big club, as he is a key part of the Blue Jays’ very bright future. 

Colby Rasmus also left last night’s game with a groin injury. He’ll be on the disabled list for a few days meaning the outfield will consist of Anthony Gose, Moises Sierra and Rajai Davis. 

The Jays have demoted lefty pitcher Brett Cecil after yet another sub-par pitching performance, giving way for southpaw J.A. Happ to join the rotation. 

On the season, Cecil is 2-4 with an inflated 5.72 ERA in nine starts, and has yet to find a groove in 2012.

The Blue Jays also designated pitcher Andrew Carpenter for assignment.
