LAKE BUENA VISTA -- The Marlins have reached agreement with the Mariners on a deal that would send first baseman Logan Morrison to Seattle for right-handed reliever Carter Capps [see stats here], according to sources with knowledge of the deal.
Morrison has been on the trading block for weeks.
Capps, 23, made 53 appearances with the Mariners last season, going 3-3 with a 5.49 ERA. Capps was rated by Baseball America as the 7th-best prospect in the Mariners' system after the 2012 system, and was also ranked by BA as having the "best fastball" in the Seattle system.
Morrison became expendable when the Marlins signed first baseman Garrett Jones to a two-year contract. But they were trying to trade him even before then following two seasons in which he battled injuries, missed significant playing time, and saw his production drop.
The Marlins are still looking for a third baseman, either through a trade or free agent signing.
I'll have more on this later as the story develops.
