Rudy went into his fantasy laboratory and came up with yet another tool. This, guys and four girl readers, is the Fantasy Baseball Buy/Sell Tool. It's about as easy to use as any of the other tools combined. It's called the Buysellatops and it looks like this. It talks instead of grunting or whatever dinosaurs did. Actually, they could've talked. We don't know. Maybe The Land of the Lost was a documentary. Who's to say? The Buysellatops has two things on its mind this week, how can we get rid of all of these pollutants and gravity so I can graze the roof? And how little can I buy [player]Jason Heyward[/player] for? Sometimes all the planets align for a great buy, this week is one of those days. This day is one of those weeks? You know what I mean. Heyward has just about reached his nadir. Unless he has a season-ending injury tonight, there's no way he can be worse. His BABIP is silly terrible. Right now, he's hitting line drives into the gap and it's hitting a pelican and falling into the outfielder's glove. If he hits .330 from now until October, it wouldn't surprise me. He is not a one hundred-something hitter. He has power and speed. Here's a comparison for ya -- he can be as good as Adam Jones the rest of the year. Rarely do you get a chance to buy low on such a highly ranked hitter, but here's your chance. As Buysellatops would say, "Get Heyward, and maybe some suntan lotion from Buchholz. This sun is so much stronger than I remember it." Anyway, here's some more players to buy or sell this week in fantasy baseball:
