As for rank, it seems to be a slightly down year for AL SS -- this wRC+ would have only ranked 5th at the position in 2013 and 2012, and 8th in 2011 (min. 400 PA).
My other note of caution is that this might be Escobar's peak. Punto certainly looked like "more than a utility player" at times, only 93-96 wRC+ but with excellent defense he projected as a 3-4 fWAR player in multiple seasons. Escobar has the advantage of age, but his record suggests that 102 wRC+ is more his peak than his average. A nice stabilizing fill-in at the position this year, for sure, but like Suzuki, he shouldn't preclude other options going forward.
Definitely gets hurt by the Liriano trade perception, in my mind. Looked like a futility infielder eating up a 40-man roster spot at the time, but he has salvaged that trade. The Morneau trade return is now at the top of the disappointment list, although he was more expensive and it was only for one month. Otherwise, Ryan has acquitted himself quite well in his recent trades (even if his 1990s vets for prospect swaps are no longer possible).
