Mariners Prospect Colt Emerson Makes MLB Debut

The Seattle Mariners promoted their No. 6 overall prospect, 20-year-old infielder Colt Emerson, to the major league roster. Emerson, who signed a record $95 million contract two months ago, was called up from Triple-A Tacoma. He was scratched from the Rainiers' lineup shortly before first pitch and made his big-league debut in Sunday's series finale against the San Diego Padres, batting ninth. The Mariners ultimately fell to the Padres 8-3 in the contest.
