first baseman Todd Helton
was arrested for DUI this morning -- and TMZ has the mug shot.
According to the police report, 39-year-old Helton was busted at 2:39 AM on 3 counts of drunk driving just outside of Denver.
Cops say Helton was cooperative.
A rep for the Rockies released a statement saying the MLB superstar "clearly understands the seriousness of his poor decision."
Helton -- a former All-Star -- was once considered one of the best hitters in baseball.
Helton just released a statement saying, "Last evening I exercised poor judgment and was charged with drinking and driving after driving to a gas station near my house. I am very sorry and embarrassed by my actions."
"I hold myself to a high standard and take my responsibility as a public figure very seriously. My entire career I have worked to set a positive example for my family and in our community and I fell far short of this standard."
"I sincerely ask my family, the Colorado Rockies Organization, Major League Baseball and the community to accept my apology. I make no excuses and accept full responsibility for my actions. I humbly ask your forgiveness.”
