Diamondbacks report

Diamondbacks 6, Guardians 4

At the plate: 1B Christian Walker, playing in his first game since Monday, when he was struck on the hip with a fastball, needed no time to shake off the rust. His first swing of the day, on a 1-0 pitch in the bottom of the second, produced a 430-foot homer to deep left field. After working a walk and stealing a base in the third, Walker missed another homer by just a few feet, flying out to the warning track in deep left-center on a ball that left his bat at 108 mph.

On the mound: RHP Zac Gallen gave up four runs in 4 2/3 innings. He walked two and struck out five. Three of the runs came in the fifth, an inning in which Gallen was called for a balk, committed a throwing error on a bunt single and allowed three stolen bases, two on a double steal. “The ball didn’t feel like it was coming out as great (in the fifth),” Gallen said. “I felt like I was losing a little bit of life.” He said he made an adjustment to his delivery earlier in the week — he thought he had been flying open too soon — and felt like it paid dividends in the early innings. Gallen seems pleased with where he is with 12 days — and likely one more start remaining — before he takes the ball on Opening Day. “For the most part, I feel pretty good about the way everything is kind of taking shape,” he said.

Extra bases: There was a strange moment in the bottom of the fourth when both Guardians RHP Nick Mikolajchak and Diamondbacks RF Yairo Munoz left the game after the same pitch was thrown. Mikolajchak left with an arm injury, Munoz with what manager Torey Lovullo called a “right calf strain.” Munoz told Lovullo his spike got caught on a swing, causing him to tweak the calf.
