Trade deadline could shake up Rankings and playoff races

With the All-Star game now in the rearview mirror, the focus moves toward the trade deadline, where Zack Greinke, Cole Hamels, and Justin Upton will be the most sought after targets. The wild card races in both leagues are extremely tight, so if those stars land on contenders it could really move the needle as the playoff races heat up.

NOTE: All stats are through Sunday, July 15.

Rankings written by Ben Duronio of Fangraphs.com. The system used to rank the teams is based not on the current standings or a gut feeling about team quality, but on how well they've performed at the underlying traits that predict future performance better than wins and losses.

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.
