Could be.
In real life, if you glance at pre-arb players who do actually have salary info available, there is really a range. Some teams (ahem, the Rockies) are stingy/cheap and keep their guys nearer to 500k and other teams have performance incentives for doing well. For example, Adam Eaton on the White Sox is balling pretty hard for a pre-arb player.
To state the obvious, normally guys get a little more dough based on years of service. Mike Trout went from 510k in year 1 to a cool mil in year 2 and everyone thought it was way too cheap of LAA, but in fact pre-arb salaries that high are relatively unheard of unless they are part of a long-term deal buying out pre-arb/arb/FA years.
