As the second half begins, 30 core questions for 30 teams -- some macro, some micro.

Arizona Diamondbacks: How much more progress will the team's young pitchers make in the weeks ahead?

Robbie Ray is getting better, clearly; will Rubby De La Rosa? How far will Patrick Corbin progress as he comes back from Tommy John surgery?

The answers to those questions will determine whether the D-backs will continue to be a factor in the 2015 playoff race and be a more dangerous threat in 2016.

Atlanta Braves: Who are the team's tradable assets now, and how much can they get for them?

The Braves' slump leading into the All-Star break served as confirmation that this is a team that is rebuilding. Jason Grilli (left Achilles rupture) is out for the year, taking him off the market, but Cameron Maybin is a good sell-high candidate. Could A.J. Pierzynski bring something meaningful in return?

Baltimore Orioles: Will Chris Tillman stay on track, after throwing better in his most recent outing? Tillman was a core part of the Orioles' second-half surge last season, and he needs to be that again if Baltimore is going to run down the Yankees.

Boston Red Sox: The best possible position for Hanley Ramirez is designated hitter, it appears. So can the Red Sox have an effective roster with both Ramirez and David Ortiz, and how can they make that work, given Ortiz's stature in their history
