The Cardinals claimed Young off waivers from the Cubs on Monday.
The Cubs had removed Young from their 40-man roster last week and he'll now join one of their division rivals. The 28-year-old turned in a .310/.417/.577 batting line with 21 home runs over 90 games this season at Triple-A Iowa. He's slashed .210/.290/.435 across 22 contests at the major-league level and can handle the corner infield and outfield spots.
