Jason Bartlett - SS - He's hitting only .249, which is well below his career average of .277 and he career best of .320, but he does steal some bases (15) and his strikeout/ AB ratio is 1:6. This tells me that he's putting the ball in play, if he starts putting the ball into the gaps, he could finish up with over 150 hits and 30 stolen bases. Bartlett's defensive skills are very good, so you know he be in the lineup virtually every night.
Jeff Keppinger - SS/ 2B - Last year, he hit .288 w/ 34 doubles. Had a late start this year (only played 29 games so far), but he's batting .325. His strikeout/ AB ratio is about 1:18 and it really seems like all he does is hit doubles.
Daniel Murphy - 1B, 2B, 3B OF - Owns a .297 BA through 75 games. Could finish with about 160 hits, w/ 30 doubles. He's an everyday player who you can use in four different player slots.
Reed Johnson - OF - In 48 games, he's the owner of a .337 batting average, 11 doubles and 22 RBI.
Ivan Nova - SP - He's 7-4 and is a starting pitcher for the NY Yankees. ERA of 4.26, but he gets plenty of run support from a powerful lineup
Mark Buehrle - SP - His 3.73 ERA is the best it's been in years. This is his 12th MLB season and he's had only one losing season (2006). He's always been a solid pitcher and has perfect game and a few no-hitters to back it up.
Charlie Morton - SP - Is probably the biggest reason the Pittsburgh Pirates could finish the season with a winning record. Has only given up 2 home runs in 86 innings pitched.
