Fantasy Baseball: Top 5 "Sell High" Trade Candidates

I'll admit it. I know as much about fantasy baseball as I do quantum physics.

But, I do know which player performances are the real deal and which are not.

That hot hitter who never hit more than 10 home runs in a season or that dominant pitcher who is sporting a sub-two ERA and will probably come back down to Earth at some point.

Here are 11 trade candidates that you might want to consider moving while the demand is still high.

Ryan Vogelsong

Don't let the 4-1 record and 1.68 ERA fool you. 

With a career 5.25 ERA and sub-.500 record, this journeyman may return to normal after awhile.

If Vogelsong is on your roster, trade him for a bat that may help your team in the long run before his ERA catches up with him.

Lance Berkman

Berkman is having an outstanding start to 2011.

However, it is questionable whether he can play everyday for a full season.

At 35, Berkman may start acting his age once the dog days of summer hit St. Louis.

Deal him now if you can for an offensive replacement.

Asdrubal Cabrera

When I see the year Cabera's having (10 HRs), I think about the year Jose Bautista had in 2010.

Both never hit many home runs prior to each season in question and all of sudden started raking.

The only thing to consider when weighing the reality of Cabrera's numbers is that he is only 25.

Power, however, is not in repertoire.

Owners should consider moving him in case Cabrera has a power outage.

Alexi Ogando

Ogando has been impressive thus far in 2011.

However, pitchers are difficult to gauge early in their careers.

Hitters either don't figure them out right way, or once the book is out on them, hitters find a way to make the youngster pay.

Ogando may turn out to be the real deal, but if you receive an offer for Ogando, take it.

Matt Kemp

With 17 HRs and 50 RBI, Kemp is off to a great start.

Maybe, Kemp has finally received the message and turned into the player everyone thinks he can be.

However, if he falls into the mental trap that sapped his production in the past, prepare to move him immediately.
