I remember Mike Morse had a spring like Vogelbachs. Then I looked it up.
He hit
| .492 | .548 | .769 | 1.317 |
in 2008 and led the Cactus league in everything. Then he played part time for a week, tore his labrum and was traded to the Nats the next year.
In 2014, Brad Miller hit
| .410 | .478 | .836 | 1.314 |
That ST earned him full time play. He hit
| .221 | .288 | .365 | .653 |
in 123 games.
If memory serves, in 2014, Miller struck out too much because his swing was too long. Also, he seemed anti-clutch, that is, he played worse in big games.
I think Morse, Miller and Vogey have had the best Cactus lines the Mariners have ever produced. The thing they seem to have in common is mammoth power. Morse and Miller probably prospered in Spring Training from the lack of booking, but the holes in their swing caught up to them once the season started.
I agree with Doc that mammoth power and excellent eye can only mean good things and Vogelbach's career looks much brighter than Morse and Miller's. Also, those guys have been productive major leaguers in their own right.
