The Providence Journal's Brian MacPherson—one of the best baseball writers anywhere—has an intriguing article on what roles Mark Melancon and Alfredo Aceves might play for the 2012 Red Sox. In a stat-laden article about 'inherited runners' and 'run expectancy', McPherson makes a compelling case for putting both Melancon and Aceves into the set-up role Bard performed so well in last year. With all the indecision still rampant with Red Sox pitching (including the fact that we still don't have a pitching coach!), this article will ease your mind a bit. (Photo by J.
