Those points are valid and catchers should obviously focus on trying to prevent as many as they can. Looking at the stats, the Sox are tied for second with 7 other teams with 4 PBs, which isn't great (Marlins lead the league with 6). They also check in at 26th with 7 WPs this season (the Tigers are in first with a whopping 25). While the PB portion could absolutely use some shoring up, the Sox and their Cs seem to be doing a great job at limiting WPs. It would be interesting to see if there is any direct correlation on the way C's set up leading (or not leading) to more WP/PBs.
