Pretty even dimensions, left center still a tad shorter than right center, but don't think that it'll matter.
In general I prefer the AL hitters, although Alvarez & Harper both have a nice uppercut swing. Wright imo isn't really suited for that kind of competition with his swing and the rest Cuddyer, Alvarez & Harper are rookies when it comes to the MLB HR derby, even though at least Harper has participated in that type of contest before (on a much smaller scale). In general Alvarez & Harper imo have that kind of uppercut swing, you need to have a fighting chance, but not sure if that lack of experience will play a role.
Cespedes/Davis certainly have the power & swing, but same lack of experience (plus the pressure for Davis since everybody is expecting him to put on a big show). Fielder has a proven track record and Cano also has the total package, so I'm thinking about the -150 on an AL hitter to hit most HRs in round 1.
