As a relatively avid fantasy baseball player, I hate the concept of selling high.
Wait, let me correct that—selling high makes me extremely anxious and subject to immediate regret. What if I was wrong about [Player X]? What if he's for real?
Take Jose Bautista from last year. Say you had tried to sell high on him by the All-Star Break—which, considering he had more home runs at that point (24) than he did by the end of any previous season, would have made all the sense in the world.
But you would have been sorely disappointed. Bautista actually had a better second half, hitting 30 home runs, knocking in 68 and batting .287 (compared to a .237 first-half average).
To be brutally honest, you can never be sure you're making the right decision when you choose to sell high on a player—unless you are blessed with psychic powers, in which case I kindly suggest you invest in more meaningful activities than fantasy baseball (you know, like the lottery).
That being said, there are certain signs you can look for in a player that indicate that he may have reached his peak value for the season. Injury history, first- and second-half splits and possible trades that may happen in real life can all determine the direction in which a player's season will head.
Here are 10 players who, for one reason or another, you may want to consider moving in order to maximize their value.
Note: This advice should not be considered for fantasy keeper leagues—this speculation focuses strictly on the 2011 season. All statistics are as of June 13, 2011 and are courtesy of baseballreference.com.
