In a surprise set of moves Friday, the Rockies designated for assignment their veteran closer, John Axford, along with longtime catcher Wilin Rosario and left-handed reliever Rex Brothers.
Right-hander Tommy Kahnle also was designated for assignment, as part of an overhaul of Colorado's 40-man roster.
The Rockies used the roster space to add minor-leaguers Trevor Story, a Triple-A shortstop and one of their most promising prospects, outfielder Raimel Tapia and right-handed pitchers Carlos Estevez and Antonio Senzatela.
And, the Rockies signed backup outfielder Brandon Barnes to a one-year contract extension, avoiding arbitration.
