At his best, Chris Davis has been one of Major League Baseball's best power hitters, with 141 homers since the start of the 2012 season, including 53 in his breakout year of 2013. The Orioles have been hanging in the American League playoff race in recent weeks, and he has been carrying them -- he has 11 homers and a 1.142 OPS since the second half began -- including a crucial homer Monday night.

At his best, Davis has been as much of a game-changer as any left-handed power hitter not named Bryce Harper. He is a good first baseman with a unique ability to throw the ball well, and he also has a reputation for being a really good teammate and a caring person.

At his worst, Davis has been nothing short of awful. In 2014, he batted .196, an average that seemed to magnify all of the strikeouts that he typically generates -- 681 K's over the past four seasons, and counting. He can go through weeks as a perpetual rally-killer.
