I like how the starters match up. Miley has averaged 7 innings a start the last month. Redmond about 5 innings. BABIP (Batting Average With Balls In Play) against Miley is only .269 with 58.3% of his batters hitting ground balls. BABIP against Redmond is .333. Redmond has struggled on the road, going 0-1 with a 7.41 ERA in four starts while giving up 25 hits and walking six over 17 innings.
Bullpens are about even over the last 2 weeks.
Hitting looks good for the D'Backs also. I know they have only scored 8 runs in the last 5 games, but they have still outhit the Blue Jays over the last week (54-42). BABIP D'Backs are ahead .325-.270. Batting average .273-.228. OBP .356-.285. Throw in the fact that there is no DH, and that favors Arizona a little more.
I would consider the run line, but Redmond can strike batters out, and that could potentially kill some high scoring rallies Nonetheless I feel pretty secure taking Arizona tonight.
