Even with his slow start, Vlad is still 74th in fWAR (only 117 in bWAR).
The bigger issue offensively is that only 5 guys have wRC+ of 100 (average) or better and they are Bo, Vlad, Springer, Heineman (playing 1/3 of the time) and Straw (playing 1/2 the time). That means that they routinely have 6 guys performing below average in the lineup.
Santander is a slow starter and they will let him heat up, but Wagner is hitting around the same level as Schneider was and Roden and Gimenez are rocking 80 wRC+s.
Varsho could be back as soon as Friday. Barger should be getting some run to see what he can do (he should be getting some reps at 3B at this point).
