I think they will get the three series wins going 6-3 or 7-2. The amazing thing about the current record is that Pedroia has been a non-factor all season (and may continue that way), Betts and Bogaerts both on the DL before May 31, JBJr-Vazquez-Leon-Swihart all below .200 most of the 60 games so far, Pomeranz a late starting dud , even Sale and Kimbrel a little inconsistent. If you didn't know about the 41 wins vs 19 losses, you would think this team was at .500 at best.
The biggest question may be whether Mookie's "sore side" is temporary or a serious oblique strain as has been opined by some.
