Chris Davis has a career .477 slugging percentage. Before you tell me that is low, Davis would rank 37th among all active player in the Major Leagues, if he was eligible (3000 PA). He would be ahead of Andre Ethier, Adrian Beltre, Brian McCann, Joe Mauer, and Jayson Werth, just to name a few.
He also has hit 25+ HR before. In fact, he has a 162 game average of 30 homers. Last year, he had a very quiet, underrated season. He hit 33 HR and had 85 RBI in only 139 games. His slugging percentage was over .500 (.501) and he was able to show off his power.
And, the Orioles will help get him up to bat. As a team, the Orioles have averaged 7.25 runs per game, with 11.75 hits per game. This will put runners on base for Davis and get him more RBI and RBI opportunity. The trick is, if you feed your power hitter, he will eat. Expect Davis to have large RBI numbers this year.
If I was to predict how Davis will do this season, I think he'll put up a .270/.310/.540 line with 47 HR and 113 RBI. But, don't count on it. He still is young and possibly unpredictable. But, if everything goes his and the O's way, he could be sitting atop the AL MVP voting.
