The latest "Mike Trout is amazing" update is a doozy.

Trout's big weekend–which included starting back-to-back games with leadoff homers–has propelled the 21-year-old Angels rookie to 10.0 Wins Above Replacement for the season.

That's remarkable for a few reasons. One is that no other player, in either league, has more than 6.3 WAR this year. Beyond that, Trout wasn't called up until April 28 and has only played 117 of a possible 140 games. And finally, the last position player to reach double-digit WAR was Barry Bonds in 2004.
