In 1994, the Rockies also only had one All Star in Dante Bichette. If you look at his numbers, his trip to Pittsburgh for the All-Star Game that year was well deserved. However, Andres Galarraga was one of a few snubs on the Rockies that year. He posted first half numbers that were very similar to that of Bichette.
Another snub was center fielder Mike Kingery. Kingery did not play at all in 1993 but the Rockies signed him in 1994 and he played very well in the first half. In particular, his slash line was very good.
However, as you can see by his games started, though, he only started 50 games. That is the primary reason why he was not an All-Star that season.
