I'd pick Stroman. He dominated Cleveland this season with defensive independent talent, there's good reason to expect continued success.
In 14 IP against the Indians in 2016:
Stroman - 9.64 K/9, 1.29 BB/9, 63.5% GB%, 1.35 FIP, 1.85 xFIP, 1.27 ERA
Following him up with Estrada in Game 2 and Sanchez in Game 3 would be lethal.
