MVO award voting is done over the season's final week by members of the local media who cover the team on a regular basis. Each ballot has three spots with a 5-3-1 point scoring system.
According to the team's press release, Davis received all first place votes except for one, which went to Adam Jones. The second place finisher in the balloting was Jones, with Manny Machado coming in third. Chris Tillman also received votes for the award.
The team lauds the achievement with this summation of the season Davis has had:
Davis has compiled one of the greatest offensive seasons in major league history. Entering today's finale, he had a club-record and MLB-leading 53 home runs and 96 extra-base hits on the season. His 138 RBI were most in the majors and fourth-most in Orioles history and his 370 total bases were a new club record. He also ranked in the top three in the American League in slugging percentage (2nd, .634); on-base plus slugging percentage (2nd, 1.003); runs (T-2nd, 103) and doubles (T-3rd, 42). Davis is only the third player in MLB history to hit at least 50 home runs and 40 doubles in a season, joining BABE RUTH (1921) and ALBERT BELLE (1995).
This is not a surprising outcome. Had anyone other than Davis won, that would have been the shock. Still, it's a well-deserved recognition of the outstanding season he's put together. We just watched the most home runs an O's player has ever hit in a single season. That is pretty cool.
