Colorado Rockies legend Todd Helton was sentenced to 2 days in jail over a 2019 incident ... this after the 46-year-old pleaded guilty to DUI in court last month.
Todd was busted in Knoxville, Tenn. on March 18, 2019 after cops say the former MLB first baseman lost control of his truck and crashed it into a telephone pole.
Officers say when they arrived on scene ... Helton was being taken care of by emergency medical personnel -- and had admitted to taking Ambien before getting behind the wheel.
But, in the police report, cops say they found a plastic cup that reeked of booze inside his ride .
