According to one insider, the Philadelphia Phillies will compete with the New York Mets at the MLB trade deadline over the same group of high-leverage relievers.

The New York Mets came into Thursday with a five-game lead over the Philadelphia Phillies in the NL East, and how that race for the divisional crown shakes out could be determined by how both teams handle the MLB trade deadline.

This will be a fascinating deadline for Dave Dombrowski, who has to issue a referendum on this roster's chances for a World Series title.

The Milwaukee Brewers and Philadelphia Phillies begin a 3-game series Friday at Citizens Bank Park in Philadelphia.

The Cardinals sit 5.0 games behind the division-leading Chicago Cubs, with the Brewers just 0.5 games behind St. Louis. The Cardinals are in desperate need of a turnaround, having lost seven of their last ten games—including four straight.
