1. RHP Corbin Burnes looks ready to go. The Diamondbacks’ new, high-priced starter struck out all three batters he faced in an efficient inning of work. He was in the low-to-mid-90s with his fastball and got help from a challenge when catcher Gabriel Moreno asked for a two-strike review.

Burnes admitted later he had forgotten the new wrinkle that was in effect on Friday afternoon at Salt River Fields. He had forgotten that pitchers, catchers and batters could challenge ball-strike calls by appealing to an automated strike zone.
