Former top prospect Jon Singleton returns to Astros on minor-league deal

The Houston Astros have signed former top prospect Jon Singleton to a minor-league deal and sent him to Triple-A Sugar Land. Singleton played just 114 major-league games with the Astros, struggling with marijuana addiction and receiving three drug suspensions. The Astros' first base situation is currently a mess, with free-agent signing José Abreu struggling and Mauricio Dubón starting at the position despite never having played there professionally. The team hopes Singleton's power and plate discipline from the left side could provide some much-needed depth.
