Left-hander Ron Mrozinski , a 19-year-old pitcher, was signed by the Philadelphia Phillies as an amateur free agent before the 1949 season. Ron's first assignment was with the Carbondale Pioneers of the North Atlantic League where he went 10-12 with a 4.34 ERA. Ron pitched in the low minors for the next four seasons, coming up with a 53-48 record for his four years work. He was invited to Philadelphia to show his stuff about the same time television did.

The left-hander had a 1-3 record in 37 games along with a 5.36 ERA in his two years, working mainly in relief during his short stay in the major leagues in 1954 and 1955.
