Every MLB season a team seems to surprise us and overachieve.
They compete in their division and sometimes even win it when we expected them to be out of the race by the All-Star Break.
This year it seems there are a few teams like that which makes this trade deadline more interesting then others in the past.
Here is a list of 4 teams who will be buyers at the trade deadline after we expected them to be sellers before the start of the season.
The Tampa Bay Rays may not be as big of a surprise as other teams on this list but they still seem to be playing better than their roster says they should.
The Rays are currently nine and a half games out of first place in the A.L. East but only six and a half out of the Wild Card spot and are going to be looking to acquire players at the deadline.
The Rays have a nice roster but it seemed like this was going to be a transition year from their first wing of great prospects to the next.
They signed Johnny Damon and Manny Ramirez in the offseason to plug in as stop-gaps to eventually make room for some players from their loaded farm system.
The fact they are as close to the playoffs in an extremely tough division this deep into the year makes this season a successful one.
The Rays have a bright future ahead of them and should be buyers at the deadline for years to come.
The Arizona Diamondbacks seemed to be a team in limbo, not quite good enough to contend but not bad enough to start an entirely new rebuilding process.
But that was before this season and the Diamondbacks have shocked us all.
Arizona is part of a two team race in the N.L. West with the San Francisco Giants and jockeying for position in the Wild Card standings.
The Diamondbacks are four games out of first in the West and with a quality acquisition at the deadline could set them up to win that division.
If they pulled if off and sneaked into the playoffs they would be the surprise story of the year and be great for the future of their team.
The Diamondbacks may not be in the running to trade for a huge piece at the deadline but a few upgrades to their roster could go along way.
The first major "surprise team" of this list is the Cleveland Indians.
Before the season started it seemed the Indians were in for another losing season and another trade deadline in which they sold off many of their assets.
The Indians shocked us and are now fighting for first place in the highly competitive A.L. Central.
The Indians, like the D-Backs, won't try and land a huge chess piece at the deadline but could make a few upgrades to their lineup or simply acquire some depth.
The Indians are playing with house money at this point and if they stayed in the race until the end of the year their season would be a success.
With that said, they could win their division and it seems like the team who does the most at the deadline will have the best chance of doing that.
The Pittsburgh Pirates are going to be buyers at the trade deadline for the first time in my life.
That's right, while I am only 19 years old its been about that long since the Pirates have played competitive baseball and are currently tied for first place in the N.L. Central.
The Pirates may shock us all and land a Carlos Beltran type player but more realistically they could go after someone like Carlos Pena.
Pena's power could be a huge help to the Pirates lineup and his defense at first base would be an upgrade as well.
The Pirates have drafted near the top of the draft for the past 20 years and similar to the Tampa Bay Rays rise up in 2008, this could be the start of a long stretch of great baseball in Pittsburgh.
I'm sure Pirates fans aren't thinking of it like that, though, and are probably enjoying every minute of their Pirates in the buying market.
