Its a good team overall, but somehow... I dunno. It just feels like for a 10 team league you should have been able to avoid guys like Glaus, KazMat, Drew, and Mora. Or at least gotten better replacements. I'm not sure what round you took various people in, but I just get the sense that you took some of those pitchers too early in the draft, and as a result missed out on a couple other sticks. I'd scour the waiver wire in your league ASAP, see if you can find some other names to fill out the roster better.
Biggest red flags are Arroyo, Salty, Weeks, and Izzy. I can easily imagine all four of them having years that don't justify their draft position in your league. You know... the kind of year that makes you wish you'd taken them 2 or 3 rounds later. Just a thought. Keep a close eye and a short leash on all 4 of them. Make sure your team can survive without 'em.
As of 8/4/13 C:Napoli 1B:Goldshmidt 2B:Kinsler, Gyorko SS:Tulo, Profar 3B:Longoria, Machado, Middlebrooks OF:Harper, J. Upton, AGon, R. Davis, Venable SP:Scherzer, Minor, Ryu, E.Santana, Beachy, Samardzja, J.Johnson (DL), T.Ross RP:Perez, Rodney, Farquar
Not a huge fan of either of your catchers, especially in a 10-team league. I'd be looking elsewhere on the WW and would personally drop AJ. I'd stash Salty on the bench and look for two other starters. I'd be checking to see if B Molina is available or JR Towles or G Soto.
Overall I'd think your well-balanced enough, but I'd be looking for an upgrade at C in the near-term future. (and keep Salty until he arrives at the MLB).
