The Cubs picked-up Shawn McGill from the Lincoln Saltdogs:
McGill, who will turn 25 at the end of February, took over as Lincoln's starting catcher in late May and went on to post an outstanding 2008 season. The Rhode Island native hit .299 with nine home runs and 43 RBI on the year. His nine homers tied him for the active team lead, and he led the team outright in triples (six) and times hit by pitch (16). Shawn ranked second on the squad in RBI and walks as well. McGill also showed versatility in the field, appearing as an outfielder in 18 games. After the season, he was ranked by Baseball America as the fourth-best prospect in independent minor-league baseball, as well as the top American Association prospect and the top independent catching prospect.
You always need lots of catchers in camp, but McGill could also be useful down the road.
