He's not on the 40-man, and I'm not advocating making him the starting SS, but Fontana is off to a nice start in AAA, and would be an interesting leadoff or #2 hitter experiment. I'm curious what the Astros' plan is for him, considering they also have Marwin, Villar, Sclafani and Torreyes as middle IF utility types, all at AAA or MLB. Not to mention Lowrie may shift into a Zobrist-esque super-utility role (wild-ass guess) once Correa is ready.
