Marlins' Seth Martinez: Jettisoned from 40-man

The Marlins designated Martinez for assignment Thursday.

Martinez has made six appearances since joining the active roster Aug. 27, across which he coughed up four earned runs over 6.2 innings. He'll now lose his place on the MLB and 40-man rosters to make room for Ryan Weathers' (lat) return from the 60-day IL.
