From the Frequently Asked Questions thread that is pinned at the top of this forum:
Qualifications for Awards (MVP, etc):

This is another very commonly asked question, not in these forums, but in the league-chats. There is no subjectivity employed by WIS in the selection of award winners. Everything is strictly based on a formula. While they have not published what the formula is, the link above tells us what factors are considered.
There are several common reasons why the player you think should have won an award did not, even if it appears that someone with "lesser" stats did so:
-- For silver slugger, gold glove, and All-Star selections, your player has to have appeared in at least half his games at the specific position (and note that WIS considers LF, CF, and RF as separate positions.) If your guy played multiple positions, he's not going to get selected.
-- If a player was traded between leagues, it's extremely unusual (in fact, I've never seen it) for him to win an award.
-- You're looking at the wrong stats. HR, RBI, AVG, SB, etc do not matter for MVP. No matter how much you think RBIs are valuable, WIS does not consider them at all. The only offensive stat that WIS considers is runs created.
-- Park effect matters for MVP, ROY, Cy Young, and Silver Slugger. WIS considers what park you were playing in. This is why a lesser offensive player from Safeco may win the MVP instead of a player with better stats who was in Coors. And vice-versa for pitchers.
-- Defense matters in MVP voting. WIS considers the player's position and his defensive performance.
-- Playing time matters for most awards. Again, MVP considers runs created, which increases with more playing time. Your guy may look better across the board, but if he only played 140 games, he may lose out to a guy who players 162, even if the latter was not quite as effective.
