The Mariners added a pair of slugging first baseman-outfielders to go along with Robinson Cano on Wednesday, reaching agreement on a one-year deal with Corey Hart and acquiring Logan Morrison in a trade with the Miami Marlins. Hart confirmed he had agreed to the deal in a text to The Associated Press. The deal is still pending what should be a closely monitored physical after Hart missed all of last season following surgery on his right knee. Morrison was acquired for relief pitcher Carter Capps, a source told ESPN.com's Jerry Crasnick. Hart will earn a base salary of $6 million, but could earn up to $13 million with incentives, a source told Crasnick.
