He's actually close to the pace I thought was most likely for him in his rookie year. He's maintained a respectable average and OBP, and has struggled with SLG. But people need to remember he only had a .451 SLG in the minors. He is probably on pace to be a solid major league contributor, and at his cost, there's no reason he can't be in a contender's lineup next year. His OBP is going to be well above average, and his SLG is probably going to improve. While he might still be nothing more than a 790-800 OPS guy next season, even with improvement, that will be anchored by the more important OBP. The key is filling out the rest of the lineup properly. That is where the Cubs have the biggest problems so they might feel forced to replace one of their best OBP guys, even though the smarter thing to do would be to replace Jacque Jones or platoon him. Jones has kept his OPS over 800 most of the season, but it's SLG dependent, which lowers its actual value a bit, since OBP is more valuable when it comes to run production. And he is hitting just .219/.260/.370 since the All Star break. He is currently outpacing his career norms, although his AVG and OBP are right in line with those numbers. Basically, his SLG is inflated, and will likely decline by the end of the season. Jones could finish the year not too much higher than Murton in the OPS department, but at 11 times the cost. And while Matt is likely to improve as time goes on, the 31 year old (32 next April) Jones will be lucky to maintain his career numbers (he's missed that mark the past 2 seasons). Unfortunately, the Cubs probably don't even recognize this situation for what it is, and they'll be much more likely to push aside the kid with the good OBP in favor of the aging/declining veteran with the subpar OBP.
