Call-ups can make or break your team, and that's why they are so important.

Injuries in the MLB are not a given, so any player at any time could be called up to replace a roster spot.

Here is a look at the five biggest call-ups of the 2010 baseball season.

2010 has blessed Major League Baseball with a memorable rookie class.

Fantasy owners in Dynasty and Keeper leagues were quite familiar with this cast of characters long before they arrived in the show.

In commemoration of their foresight, let's take a gander at the top ten positional keepers for 2011.

Over the season, I've had to hear the media lament over key injuries. Surprisingly, when the unlucky injury-bugged teams are mentioned, the Atlanta Braves are normally overlooked.

For most baseball fans, they would look at you as if you were crazy if you mentioned that Braves have battled through several key injuries.  The Braves are believed to be lucky when it comes to the injury bug, with the exception of Chipper Jones.

The Atlanta Braves are once again looking like a championship-caliber team. The Braves have held first place in the National League East for nearly three months and show no signs of slowing down. In fact, they are showing signs of improvement. (see: Derrek Lee)

Atlanta's success has undoubtedly been a 25-man effort, but that does not mean that the incredible individual performances should go unnoticed. Here are the handful of Braves that are amongst the top candidates to win some of Major League Baseball's most coveted awards.

Despite being home to the all-time home run king, the Atlanta Braves have never been known for their ability to hit the ball out of the park. They are somewhat better known as the "Anti-Yankees," if you will. They have country accents, less money, and very little power, but they have still found ways to to win.

That Braves offense that led the charge to the top of the standings during a 20-win month of May has seemingly been relieved of command.

Going back to the All-Star break, the Braves are 7-9 since Brian McCann roped a bases-clearing double in the NL's 3-1 win in the Mid-summer Classic.

News flash—the Braves only have won one series since then.

These are not the Braves that many Atlanta fans came to recognize during a two-month span that took them from last place to a 7.0 game lead in the NL East.

Back in 2001, the first "article" I ever wrote about baseball was an amateurish ditty comparing the 2001 rookie class to a great rookie class of a generation ago, the 1986 rookie class.

I am reminded of that article in 2010 as an endless stream of amazingly talented can't-miss prospects spills into Major League Baseball.

Jason Heyward has been under intense scrutiny since the moment he set foot on a major league field. This intensified one at-bat later, when he hit his first major league home run.

He got off to a good start, but as pitchers began to learn that he would chase a low breaking pitch, he cooled off a bit. He made the appropriate adjustments, however, and was National League Rookie of the Month for both April and May.

Josh Johnson makes history each time he takes the mound.

Since he plays for the Florida Marlins, however, media outlets fail to mention him in the NL Cy Young race as often as Ubaldo Jimenez and Adam Wainwright.

Jimenez, whose 15-2 record comes thanks to a hot start in April and May, fares much better with his team's run support.

Over his first 17 starts, the Colorado Rockies pitcher went 13-1 with a 1.15 ERA. In Jimenez's last six starts, he is 2-1 with a 7.64 ERA.

On getaway day, the Braves concluded their first post All-Star break homestand with an 8-0 shutout of the San Diego Padres at Turner Field. With Tim Hudson leading the way on the mound, and Alex Gonzalez's four-hit day leading an offense that had six different players drive in runs—this was the epitome of a Braves quality win.

Atlanta currently owns a 7.0 game lead in the NL East, with an NL-best 56-39 record, as both Philadelphia and New York look up at the Braves with identical 49-46 records.
