Teams that desperately need to make a waiver deal—I explained the the process here last week—are probably the same teams that needed to make a trade deadline deal but couldn't make it happen for some reason.
What's changed just over a week later, other than it's more difficult to make a trade now than in July?
First off, a team's level of hope or desperation could change with their own wins or losses or those of a playoff contender.
Injuries can also occur. Rays center fielder Desmond Jennings and left-hander Matt Moore, D'backs catcher Miguel Montero, Rockies outfielder Carlos Gonzalez and Indians starting pitcher Corey Kluber have all been placed on the disabled list since the trade deadline passed.
Depending on the severity of the injuries, their respective teams might want to explore the waiver wire for at least a temporary replacement. Or maybe a key injury is what they needed to decide to become August "sellers."
With the first big name reported having been claimed on waivers—Alex Rios has been claimed, according to Ken Rosenthal of Fox Sports, and Evan Grant of the Dallas Morning News tweeted that the Rangers are the claiming team—the excitement that can occur in August is starting to pick up.
By process of elimination, as beat writers and reporters begin to confirm which teams didn't make a claim, the team that was awarded the claim can be identified. Then we'll wait it out as the two teams try to come to an agreement in the allotted 48.5 hours. If not, the player can be pulled back from waivers.
Here are the five teams that should be the most active in August, if only because their playoff hopes could vanish without some quick reinforcements.
