The MLB waiver wire is an awfully busy place this time of year.

As ESPN's Jayson Stark noted, "every player" in the bigs hits the the wire at some point in August. Of course, it's also an extremely mysterious place, as only a fraction of those major leaguers will make it through unclaimed and subsequently become available for a trade prior to the August 31 deadline.

With the Washington Nationals currently 4.5 games behind the New York Mets in the division, now seems like an apt time to talk about next year and the prospects who could get their feet wet with a September call-up.

Primarily due to injury, the Nationals have thrown a number of their top prospects into the MLB fire this season. So most of the team's late-season promotions will have already made their big league debuts. 

In a sport where those who fail 70 percent of the time are considered to be among the game's elite hitters, it's easy to forget how truly humbling baseball can be.

No matter a player's salary, track record of success or numbers on the season, every player inevitably finds himself in a funk at one point or another over the course of a 162-game regular season. And every player handles that funk differently.

The San Francisco Giants and the St. Louis Cardinals own October.

At least one of those teams has appeared in the National League Championship Series in each of the past five seasons, and the clubs have combined to win four of the last five World Series titles. Simply put, the Giants and the Cardinals have been there and done that.

In the process of ranking the most battle-tested squads of the 2015 MLB playoff races, there were a few key factors taken into consideration:

There's no doubt that 2015 will live on forever as the "year of the prospect." At the three-quarter mark of a season filled with youthful contributions, let's check on the stocks of MLB's current batch of top 10 prospects.

Of MLB.com's top 50 prospects at the beginning of the season, a whopping 23 have debuted in some form or fashion in 2015. By succeeding in the majors, many of those debuting talents have lost their prospect statuses this season.

This week brought teams to their 50-game marks, signaling the stretch run for the 10 postseason spots and Major League Baseball’s exciting scoreboard watching.

But Week 19 of this season brought us more than just wins, losses and jockeying in the standings. It brought us stupid quotes from a floundering team, a stupid decision from a franchise with an already spotty track record and more trade rumors, among other happenings.

The three-quarter mark of the 2015 MLB season is here, and with that playoff races around the league are really starting to heat up.

At this point in the season, the vast majority of players and teams around the league could be pegged as a "winner" or a "loser" for one reason or another, so what follows is by no means an all-inclusive list.

Mariano Rivera III is just one of the high-profile members of the 2015 MLB draft class who has already learned that playing in the minor leagues can be extremely unforgiving.

While the son of the Sandman has been an early flop in his first summer in the Washington Nationals system, the key word here is "early." After all, in the process of climbing to the bigs, nearly every blue-chip farmhand struggles at some point along the way.

It's time for the latest edition of B/R's top prospect call-up radar report!

This week, we'll take a look at six impact bats and when baseball fans can expect to see them reach the big leagues. But first, let's take a look at our handy radar system.

Since the season is well into the second half, we've had to make some adjustments. Here's what we'll use to predict the following prospects' anticipated debuts:

The 2015 MLB trade deadline was only two weeks ago, but there is already an array of contending clubs that made decisions that have proven to be highly regrettable.

Take, for instance, the Los Angeles Dodgers, who only made minor tweaks to a bullpen that has turned into a pumpkin. While clubs like the Dodgers should be ruing their missed opportunities, there is also an assortment of teams that found some flat-out bargains in the final days of July.
