Roy Halladay returns to Phillies as guest instructor (Yahoo Sports)

Roy Halladay is back wearing a Philadelphia Phillies uniform. The two-time Cy Young Award winner returned Tuesday to serve as a guest instructor in spring training. Halladay, who threw a perfect game in his first season in Philadelphia in 2010 and a no-hitter later that year in his first postseason start, is considering a more permanent role in the big leagues.
