"There were a couple of pitches I think I left up a little bit early in some at-bats," Corbin said. "Overall, I felt pretty good and felt strong."
The D-backs scored a pair of runs in the first inning on an RBI double by Lamb and a run-scoring single by Peter O'Brien.
Both of the runs came off Adam Warren, who is battling for a spot in the Cubs' rotation. In his first spring start, Warren allowed three hits over two innings.
Warren admitted he had some butterflies in his Cubs debut.
"Things were moving a little faster than I wanted them to," he said of the first inning. "It's to be expected -- I was a little jittery, anxious to get out there, especially with a new team. Just to get that first inning out of the way was really nice. It was really encouraging for me to go out there in the second inning and settle down and pitch like I know I can."
The Cubs tied things up with the two unearned runs in the second and grabbed the lead in the third on a monster home run by Dexter Fowler that was projected by Statcast™ to land 442 feet from home plate.
The D-backs reclaimed the lead with a pair of runs during a sloppy fourth inning that saw Rex Brothers throw four wild pitches and Tommy La Stella commit a throwing error.
Shortstop Jack Reinheimer, acquired from the Mariners in last year's Mark Trumbo trade, capped the D-backs' scoring in the eighth with a two-run homer, his first of the spring.
