DETROIT -- The Red Sox are still trying to figure out what they have in Tyler Thornburg, who missed a season and a half with right shoulder troubles. In a critical juncture on Saturday, Thornburg simply wasn't as effective as his team needed him to be.
The righty allowed three runs in the bottom of the sixth, two of them on a homer by Jose Iglesias, and the Red Sox lost, 5-0, to the Tigers at Comerica Park.
It had been a tight game up to that point, Boston trailing, 2-0, on the strength of a strong performance by Brian Johnson.
