If you are looking at your fantasy team, and your overall offense is looking pretty good, but you could use one more arm to fortify your rotation. Here are a few suggestions you may want to look into.
Jake Odorizzi, Tampa Bay Rays. This is one of those classic players where you should not look at his overall season numbers when you are evaluating him to add to your roster now. Plus, I know his record is 3-7 but I also know his April ERA was 6.85 and his ERA since then is 3.17. In those 54 innings since May (a 10 stretch start) he has only allowed 39 hits and 18 walks while striking out 69 batters. He might not give you wins, but he cannot control how many runs his team scores for him in any given start, but of the stats that he can control he is doing really well on.
Next is an ex Tampa Bay Ray and current Kansas City Royal (he was involved in the same trade with Jake above) could also boost your overall WHIP and ERA, but this pitcher is a reliever so he will not get you wins. Right-hander Wade Davis entered the week on a 22 inning scoreless streak that has spanned his last 19 appearances. To make the sample size a little larger, he has a 1.11 ERA with 54 strikeouts in 32.3 innings.
Anaheim Angels starter Garrett Richards should be on the radar of more people. With his win on June 20th he is now 7-2 with an ERA of 2.79. He has only given up 2 home runs while striking out 94.
If his previous owner got fed up and dropped him, then the time is now to scoop up Cliff Lee from the Philadelphia Phillies while he is still on the DL. In his previous 10 starts he has a 3.18 ERA in 68 innings. He has only given up 24 earned runs with 9 walks and 61 strikeouts.
Lastly, if you are just trying to move up a step or two in all pitching categories then you would look for a pitcher with quality starts. A quality start is defined as a pitcher who goes 6 or more innings with no more than 3 earned runs in those 6 innings. Believe it or not, Milwaukee Brewer starting pitcher Kyle Lohse has 13 quality starts this year and he has a record of 9-2 in 16 total starts.
