The injured Blue Jays outfielder finally began a rehab assignment Thursday with Buffalo, hitting a home run and drawing two walks in five plate appearances. Santander, who hasn't played since May 29 thanks to a shoulder injury, was supposed to start a rehab assignment earlier this week. Having Santander hit just left-handed would likely limit his playing time, but there are some reasons why that may not be a bad thing. The Blue Jays have been scoring runs with the best of teams this season without Santander, largely thanks to contributions from everyone on the roster. Still, there's a chance Santander could return to being a source of power, which is why the Blue Jays signed him to a five-year contract.
