First, it means that the Rockies will now have their 40-man roster complete (barring any other trades or moves). The signing of Mike Dunn brought the 40-man roster to 39 players and Amarista will (perhaps) be the last piece of that puzzle.
Second, it means that the Rockies have signed a player who has hit .230 in his six seasons with the Los Angeles Angels and San Diego Padres. He was non-tendered by the Padres last season after hitting .257 in 150 plate appearances.
His time with the Padres could be key with Colorado’s acquisition of the 27-year-old utility player.
