The Phillies have been looking for an additional outfielder with at least some major league experience and also wanted to find another left-handed bat to the bench. Carrera meets that requirement, with 384 major league plate appearances to his credit.
Indians manager - and former Phillies manager - Terry Francona referred to Carrera as having "game changing speed." Carrera has stolen 18 bases in 24 attempts in the majors and stole as many as 35 stolen bases, while being thrown out just four times, in 2011 with the Triple-A Columbus Clippers.
If Inciarte is claimed by another team, they will have to keep him on their major league roster all season, because of his status as a Rule 5 player. If he goes unclaimed, the Phillies will have to offer him back to the Arizona Diamondbacks. It's possible that Arizona will pass on taking him back or that the two teams could work out a trade if the Phillies are interested in keeping him in their organization.
