The Rockies are only four games out and are expected to make a run in the second half of the season as they always do.  In order to do that they will have to shore up their bullpen and protect closer Huston Street from being over worked.  Matt Lindstrom and Matt Belisle have pitched well in the setup role, and Rafael Betancourt gives them veteran fire power in the late innings as well.  They currently roster two lefties, Matt Reynolds and Rex Brothers.  If the Rockies make a run, they need to protect their starters (who stink this year) with a bullpen that can go 3-4 innings almost every night.

What They Need?

A proven lefty.  After trading Morales, they have a big hole to fill.  Pitching in Colorado, they can use a closer that will become a setup man who doesn't pitch to contact like Carlos Marmol.

St. Louis Cardinals 

The Cardinals bullpen is a mess, but that was expected when your opening day closer is Ryan Franklin.  Franklin has almost become a memory in that bullpen and is all but been replaced by Fernando Salas.  While Salas has pitched well, he's the ideal closer for Tony LaRussa.  He's actually an ideal setup man with a rubber arm that can go two inning if needed.  LaRussa wants a veteran and as long as the Cardinals are positioned to make a run they will trade for one.  Eduardo Sanchez is on the DL, but will be invaluable to the bullpen along with Jason Motte. Mitchell Boggs is also an effective middle man, but lefties Trever Miller and Brian Tallet are leftovers from other teams and won't do well down the stretch.  The Cardinals bullpen is ranked 24th in ERA at 4.30 and are a miserable 22/35 in saves.

What They Need?
Expect the Cardinals to sign a closer to closeout games.  LaRussa's dream would be a Sanchez/Motte 7th inning, Fernando Salas 8th inning, and Heath Bell in the 9th.

Philadelphia Phillies

The Phillies don't have the biggest needs and will not be desperate to add to their bullpen.  However, they have a team built to win and will fill any holes they feel that they have.  Right now their bullpen is stable with Madson, Bastardo, and the always ailing Jose Contreras.  They are backed up by aging Danys Baez, then Kyle Kendrick, Juan Perez, and David Herndon.  They are expecting Brad Lidge to return.  If he returns to form and is Castor Lidge and not Pollux Lidge (Gemini Twins), then he will fill the hole they need at back up closer/setup man.

What They Need?
Phillies need a proven veteran lefty.  If Lidge doesn't work out and if Contreras is hurt as we expect, they will go after a second closer like Heath Bell

Texas Rangers 

For a team in first place, the Rangers have one of the worse bullpens. Their bullpen is ranked 26th with a 4.38 ERA and is 19/31 in saves.  Closer Neftali Feliz has been erratic all season and has four blown saves already.  After Feliz they have two aging lefties in Darren Oliver and Arthur Rhodes.  Mark Lowe, who was once considered for closer, hasn't had a good season and was demoted to AAA for a short amount of time.  If the Rangers want to find success in the playoffs or even make it, they will need to add one or even two more arms to their bullpen.

What They Need?
The Rangers need a top flight setup man and frankly a second closer.  Someone along the lines of Carlos Marmol, Joel Hanrahan, or Joakim Soria.  A Fernando Rodney for the 7th inning would help as well.

Cleveland Indians

The Indians have been a pleasant surprise in 2011, but they are fading.  If they can hold on, they will make a move to add depth to their bullpen, which ranks 4th overall with a 2.99 ERA. Chris Perez has done an outstanding job, but at 26 he only has 190 innings in his career and has never pitched more than 63.  IN fact, they only have one reliever (Chad Durbin) over the age of 28.

What They Need?
Another lefty to compliment Tony Sipp.  Possibly another closer to add depth for setting up Perez or resting him.
