The Tigers claimed Diaz off waivers from the Giants on Monday and optioned him to Triple-A Toledo.
Diaz appeared in just six big-league games with the Giants this season, but he should have a clearer path to resurfacing in the majors with a Detroit squad that has struggled to generate production from most of its starting infielders throughout the season. He'll look to get off to a good start with Toledo before potentially getting the call to Detroit at some point in the next two months. In a corresponding move, the Tigers designated left-hander Zach Logue for assignment.
