Joe Kerrigan is the Pirates' new pitching coach

In a story that literally popped up on the PG's website minutes ago, Paul Meyer is reporting that veteran pitching coach Joe Kerrigan has been tabbed for the Pirates' open position. Kerrigan's been the pitching coach in Montreal, Boston, and Philadelphia. I wonder if his history of working with a hard-throwing, short-tempered pitcher named Pedro Martinez and the problem the Pirates have with Ian Snell have any correlation.
