Arizona Diamondbacks right fielder Justin Upton vetoed a trade to the Seattle Mariners, a person with knowledge of the situation said Thursday.
The person asked to remain anonymous because Upton’s decision had not been made public. Upton’s contract gave him the power to turn down a trade to a short list of cities, Seattle included.
The Diamondbacks have a glut of outfielders and Upton, a former All-Star, is by far the most marketable. He is coming off a subpar season in which he was bothered by a thumb injury.
Upton’s rejection of the trade first was reported by FoxSports.com, which said Seattle offered four players in the deal — relievers Charlie Furbush and Stephen Pryor, infield prospect Nick Franklin, and one of three pitching prospects; James Paxton, Danny Hultzen or Taijuan Walker.
