It seems like this team really sucks at hitting with RISP, so I looked at the stats. For the season the Sox are actually 4th in MLB with RISP with a .267 AVG.
Then I looked at the last 30 days and the Sox are 27th in MLB with a .231 AVG.
Not sure if last 30 days is just an anomaly or a reason to be concerned but those are the numbers, and yes, I used AVG instead of OPS because with RISP you're really looking for hits and not quite as concerned about SLG.
