A year ago on this forum I suggested that Sam Travis was a mirror image of Seattle's Dan Vogelbach, another defensively limited first baseman and former teammate of Kyle Schwarber (Travis at Indiana University and Vogelbach with the 2015 Double A Tennessee Smokies).
The 2018 projections are similar for Travis and Vogelbach, who were born about eight months apart and who each remain under team control for six seasons:

Each has displayed power this spring, posting these numbers entering Sunday's games:
ST 47 PA, .267/.298/.622/.920
DV 51 PA, .400/.529/.850/1.379
Vogelbach may get his shot to start at first base as projected starter Ryon Healy recovers from hand surgery.
