D-backs Probable Pitchers

Bumgarner made five Opening Day starts for the Giants, including one against the Padres last year. The D-backs signed him to a five-year, $85 million free-agent deal this past winter to replace Zack Greinke at the top of the rotation.

Paddack called his duel with D-backs ace Madison Bumgarner "a cowboy showdown." It will be Paddack's first Opening Day start. After a series of restrictions and workload limitations in 2019, Paddack will be turned loose in '20.

Ray was outstanding in his Spring Training starts and carried that over into Summer Camp. A free agent at the end of the season, Ray dropped weight this offseason due to a change in diet and new workout regimen. He hopes an adjustment to his mechanics -- he’s shortened his arm action -- will pay off with better command.

Lamet is a popular pick for a breakout 2020 season, and there's plenty of evidence to support that. He was dominant in Spring Training and Summer Camp and has harnessed two spin weapons -- his high-octane slider and a sharp, biting curveball.
