Davis hit .348 with eight doubles, nine home runs and 28 RBIs in 27 games in April.
"For a power hitter, he's been pretty consistent so far," manager Buck Showalter said. "Defense and how he's handled the success that's come his way is the thing I'm most proud of. I think we all know, Chris, his contact-to-damage ratio is pretty good."
Davis received a specially engraved crystal trophy and an engraved watch from MLB.
In recognition of Davis' performance, the Orioles will donate $2,500 to Luke's Wings, a non-profit military organization dedicated to the support of current and former service members who have been wounded in battle. Luke's Wings provides families with the means to visit injured service members during their hospitalization and rehabilitation.
Davis also has pledged to donate $100 for every home run he hits this season to Luke's Wings.
The first baseman hasn't slowed down his offensive pace in May. In 88 at-bats entering Wednesday's game, the lefty was hitting .341 with eight home runs, 10 doubles and 19 RBIs.
