Christian Carmichael, a 19-year-old catcher in the Mariners’ Minor League system, has been suspended for 50 games after he tested positive for a performance enhancing drug, according to the Office of the Commissioner.

Carmichael is presently listed on the roster of the Class-A Clinton Lumberkings in the Midwest League.

The catcher hit .182 last year, in 11 at-bats for the Mariners of the Arizona Rookie League.
