— The Tigers made an unusual bet on a player with no major league experience, signing 22-year-old infield prospect Colt Keith to a six-year contract Sunday that guarantees him $28,642,500.

His deal includes three team options that could make it worth $64 million over nine seasons, and the Tigers said there are escalators that increase the value to $82 million over nine years.

Keith is ranked the No. 22 big league prospect by MLB.com.

A left-handed-hitting third baseman and second baseman, Keith is from Zanesville, Ohio, and was a fifth-round pick in the 2020 amateur draft out of Biloxi High School in Mississippi.

Keith gets a $2 million signing bonus and salaries of $2.5 million in 2024, $3.5 million in 2025, $4 million each in 2026 and 2027 and $5 million apiece in 2028 and 2029. Detroit has a $10 million option for 2030 with a $2,642,500 buyout, a $13 million option for 2031 with a $1 million buyout and a $15 million option for 2032 with a $2 million buyout.
