For some teams, questing for a World Series trophy requires sticking with whatever's working.
The Toronto Blue Jays don't have that luxury.
Things are mostly good for the reigning AL East champs. Their 68-52 record puts them a game ahead of the Baltimore Orioles and Boston Red Sox in this year's race. They're 57-38 since opening with a thud in April. Neither the Orioles nor the Red Sox have that kind of momentum.
The prime mover in the Blue Jays' 2015 success was their offense, which is still going strong with the third-most runs in the American League this season.
