The talk of the baseball world the past few weeks has been about the trade market, and understandably so, as a number of high-profile players, headlined by David Price and Jon Lester, changed teams at the deadline.
Teams can still explore trades via waivers, but there are also a number of contenders who will be getting notable in-house additions for the stretch run as key players return from injury.
What follows is a ranking of nine players who are currently sidelined who could have the biggest impact on the 2014 pennant races.
Players were ranked strictly based how much they mean to their respective teams' chances of making the playoffs and succeeding beyond that once October rolls around.
It should be noted that players injured in August were not considered for this list, so you won't see the likes of Andrew McCutchen, Anibal Sanchez or Hanley Ramirez, among others. This was strictly a look at players who have been shelved since before the trade deadline but could return to make a significant impact.
