Singleton has been reassigned to minor league camp, MLB.com's Brian McTaggart reports.
EDGE Analysis
Singleton was 4-for-21 at the plate during Grapefruit League play, scoring three runs and driving in two during what will end up being a short spring. The next step for the 25-year-old, who was removed from the team's 40-man roster in April, remains to be seen. Singleton should still get some run at Triple-A Fresno, but after hitting just .202 and striking out at a 24.8 percent clip last year, he'll need to quickly turn things around in order to even keep his job there.
