The Toronto Blue Jays just got stronger up the middle.

Not content to let the hot stove season pass them by, the Jays sent outfield prospect JB Woodman to St. Louis in exchange for shortstop Aledmys Diaz.

​​Diaz, a 2016 All-Star with the Cardinals as a rookie, is coming off a more temperate season. He swatted a pedestrian .259/.290/.392 this past year, and found himself booted down to Triple-A for his troubles.

Toronto will hope that they're getting the first-year version of the 27-year-old Cuban, who is still a career .283 hitter at the top of what ought to be his athletic prime.

The Cardinals receive Woodman, a 22-year-old left-handed hitter who most recently plied his trade in Class A ball. Given his roughness around the edges, it will be a good couple of years before we get a sense of who won this trade.

Could this be an appetizer on the way to Toronto packaging up slugger Josh Donaldson in a blockbuster deal? Stay tuned, folks.
