Fantasy: Greinke's regression should have been expected

What's wrong with Zack Greinke? It's a question many people are pondering this season and fantasy players are trying to trade him. The answer is simple: nothing. If you thought Greinke was going to put up similar numbers to last season, you didn't look at the statistics closely. A strand rate of 79.3 percent and an extremely low HR/FB rate of 4.5 percent indicated Greinke would see some regression.

But Greinke hasn't pitched poorly. Unfortunately, he had nowhere to go but down after a 2.16 ERA and 1.07 WHIP last season. He is 2-8, but as I always stress, you can't measure a pitcher on wins. Teammate Brian Bannister has an ERA 1.35 higher than Greinke and has seven wins.

Greinke isn't as dominant as last season and because of that, the perception of him is negative. Greinke's value is down and is someone to acquire. Here are some other players causing concern.

Gavin Floyd (White Sox): Floyd was one of my buy lows early last month and that window has probably shut. Floyd had some bad luck to start the season and has turned things around. Floyd has just two wins, but has a 2.56 ERA and 1.04 WHIP with a 32/10 K/BB ratio in 312/3 innings in June. Don't be fooled by the 4.80 ERA and 1.37 WHIP. You want him.

Wandy Rodriguez (Astros): Rodriguez has had some bad luck, but my eyes tell me something isn't right. He had a start pushed back earlier this year because of back spasms and I wouldn't be surprised if it's still bothering him. Rodriguez had a K/9 of at least 8.45 the last two seasons and it's now 6.09, while his BB/9 has gone from 2.76 to 3.87. Don't bet on a rebound.

Aramis Ramirez (Cubs): Ramirez returned from the disabled list Friday and went 0-for-3 with a walk and two strikeouts. It remains to be seen if the time off helped him get healthy, but his strikeout rate of 25.1 percent is almost 10 percent higher than his career mark. Ramirez is batting .165 and I have to believe it's because of injury. His value is extremely low and I'd take the chance on him.

Carlos Lee (Astros): Lee is batting just .228, but after a .183 April, he hit .224 in May and .277 in June. Lee's batting average on balls in play (BABIP) of .224 is well below his career mark of .288. The power is back with 10 home runs after none in April. Expect a strong finish.

Stephen Strasburg (Nationals): A good sell-high candidate. In non-keeper leagues, you should find out what you can get for the righthander. As dominant as Strasburg is, the Nationals will be very cautious with him and limit his innings. If you're in a tight race come September, you might lose him.
