I think they will be marginally better but the 9 game run was certainly a bit "flukey" and probably not sustainable with this roster.
Hard to say if it will be good enough to hold off the Cubs.
I don't have data to back it up but I feel like the Cubs hitters are more apt to scratch some runs in a bad wind situation.
Brewer hitters are far too geared to hit fly balls.
My gut says Cubs three to one.
As ugly as that looks Weimer pointing the bat straight out across the plate only to put it back behind his shoulder is far far far worse. At least with Tettleton the bat head is relatively close to the proper launch point even if the angle is wrong.
