Serven has struck out 20 times across 42 plate appearances during Cactus League games this spring.
Serven is all but locked into a roster spot, so even his slow spring performance isn't likely to change his status for Opening Day. However, he may lose out on playing time to Elias Diaz -- the Rockies' other catcher that will start the campaign in the majors --until he can show he can get back on track at the dish.
