Hernandez & Kingery -- the Phils are kind of screwed no matter what they do. The market is awash in available 2nd basemen, so the Phils have no chance of getting good value for either player. And Hernandez only has 1 year left on his contract before he can be a FA, so that diminishes his value. Kingery would have been better served with another year in AAA, especially since he struggled so much this past season. Compound that with the Phils, in a move that still baffles me, signing of Kingery to a long contract for significant $$, means that he's not going for anything close to his value.
I'm a Hernandez fan, and think the Phils undervalue him.
As the Phils can't get much for either player, I think the best play for the Phils is to go into next season with Hernandez as the starter, and with Kingery as the backup at 2nd, SS, and 3rd. Depending on how Hernandez does next season, and how the Phils do, the Phils may elect to move Hernandez near the trade deadline. If they don't trade him, they either resign him, or they allow him to walk and have Kingery as his replacement.
The Segura trade appears to be a positive on multiple levels. It stabilizes the SS position, it improves the Phil's batting lineup, it allows Hoskins to move back to 1st, and it removes Santana from the team (decent OBP, but disappointing bat last season). I am sorry to see Crawford leave, but he can't seem to stay healthy, and as
@LundyPSU mentioned, his bat has not been all that productive since rookie ball and the very low minors (in part due to injuries).
