This past week saw the conclusion of interleague play in its current format -- the Astros are relocating to the American League next year, which will force it to be a regular, season long occurrence -- and as usual, the AL dominated. AL teams won 142 of the 252 match-ups, good for a .563 winning percentage, and outscored their Senior Circuit brethren by 108 runs. This is the ninth consecutive year that the AL has come out on top, and its 142 wins is the third most that either league has racked up in one season of match-ups since interleague play began.

The good news for the NL contenders is that they won't have to play another AL team until the World Series, so they can now go back to padding their records against some of the weaker teams in their own league. No team will be happier to see interleague play end than the Rockies, however, as they managed just two wins in 15 tries against AL opponents.

wRC+ is an offensive index where 100 is league average and every point above or below that denotes how far from league average a player's performance has been up to that point. It is adjusted for park and league, so it takes into account the context of a player's surroundings, and allows for comparison of performance from players in different situations and in different times.
