The Arizona Diamondbacks return to Chase Field on Tuesday, August 11, to host the Colorado Rockies in a 9:40 PM ET start. Left-hander Mitch Bratt gets the ball for Arizona against Tomoyuki Sugano for Colorado. With the NL West race always relevant context, this is a divisional matchup that carries weight beyond the box score — and a chance for the D-backs to build momentum at home.

Pitching Matchup: Mitch Bratt vs. Tomoyuki Sugano

Mitch Bratt draws the start for Arizona. The young left-hander has shown flashes of real potential, and a home start against a divisional opponent is exactly the kind of opportunity that can define a pitcher's season. How he handles Colorado's lineup top to bottom will be the storyline to watch on the mound.

Tomoyuki Sugano starts for the Rockies. The veteran right-hander has experience working deep into games, and Arizona's lineup will need to be disciplined early against him. Sugano tends to work with command rather than pure velocity, which puts a premium on the D-backs making him throw strikes and working pitch counts.

Keys to Watch

Corbin Carroll Sets the Tone Early

With Lars Nootbaar leading off and Carroll hitting second, Arizona has speed and on-base ability near the top of the order. Carroll's ability to get on base and put pressure on the Colorado defense in the early innings could set the tone for the entire night.

Ketel Marte in the Cleanup Spot

Marte hitting fourth is a significant vote of confidence. He is one of the most reliable bats in this lineup, and with Moreno batting third ahead of him, there is real run-scoring potential in that part of the order. If Colorado pitches around anyone, it figures to be Marte — which makes his at-bat approach critical.

Nolan Arenado at Third

Arenado brings Gold Glove defense and a professional approach at the plate. His presence at fifth in the order gives the lineup a legitimate middle-of-the-order threat and takes pressure off the players around him.

Bratt's Command in the Zone

For Bratt, the key is simple: throw strikes, work efficiently, and keep Colorado from getting extended rallies going. Chase Field can play as a hitter's park in the right conditions, so limiting walks and keeping the ball in the yard will matter.

Prediction

Arizona has the lineup depth to do damage against Sugano if they stay disciplined and work counts. The real question is how long Bratt can keep Colorado off the board. If he gives the D-backs five or six quality innings, Arizona's offense should be able to take care of business at home. D-backs win, 5-3.
