The Dbacks have 3 RH starters going in the series(Pfaadt is apparently game 1, I assume Gallen and Kelly will follow him). All 3 have fairly normal RH vs LH splits. Safe to say we'll use a LH heavy lineup where possible. Yelich, Contreras, Santana, Canha, Adames, Tellez, Donaldson, Frelick, Monasterio. Expecting a lineup something like that. They could go with Mitchell in the outfield, Tellez on the bench, Canha DH for better defense if they want. Taylor will enter the game as soon as they use one of their likely 2 LH relievers against Frelick or Mitchell. They also may roll Turang for defense or at the very least will use him as a defensive replacement late game. Bench spots I'm guessing Caratini, Turang, Perkins, Taylor, Winker, Miller...for 15 position players. If we had a 3rd catcher on the 40 man, I would have thought they'd have him over Miller to allow flexibility for pinch running...but we don't so that's out.
For pitchers, the locked in are Burnes, Woodruff, Peralta, Williams, Payamps, Peguero, Megill, Uribe, Milner. Thats 9 locks, probably 2 of Miley, Rea, Chafin, Wilson...with my guess being Chafin and Wilson. I would think Rea over Wilson, but he pitched a lot this weekend so I don't think he would have a shot.
