What are teams looking for?
A rundown of each team's offseason needs and wants
Here is a look at what each of the Major Leagues' 30 teams may be looking to do to address their needs this offseason.
Blue Jays: The Blue Jays' situation could change significantly depending on whether they move third baseman Troy Glaus, but at present they are searching for catching and infield help and could move arbitration-eligible outfielder Reed Johnson to fill one of those needs.
Orioles: Baltimore is seeking another starting pitcher, bullpen help and a power-hitting outfielder and might deal shortstop Miguel Tejada to fill one or more of those holes.
Rays: The Rays are looking for a starting pitcher, shortstop, catcher and middle relief help, and could deal such players as Rocco Baldelli, Akinori Iwamura, Elijah Dukes, Edwin Jackson, Carlos Pena or perhaps Carl Crawford for the right offer.
Red Sox: Backup catcher and bullpen are remaining needs now that Curt Schilling has been re-signed, and the Sox will try to retain third baseman Mike Lowell, but if not, the club could move Kevin Youkilis to third, go after a free agent like Alex Rodriguez or try to trade for a player like Texas' Hank Blalock.
Yankees: The Yankees could be facing the prospect of having to replace Rodriguez, Mariano Rivera, Jorge Posada, Andy Pettitte and Roger Clemens this offseason, though it is unlikely they will lose all four free agents.
Indians: There are no untouchables on the roster but the defending division champs do not figure to be very active this winter, though they will try to upgrade wherever possible and would especially like to land a corner outfield bat.
Royals: The Royals are looking for one or two back-of-the rotation starters and a middle-of-the-order outfield bat, and they could deal prospects or veterans like Emil Brown, Jorge De La Rosa or Angel Berroa to get them if they can't find suitable free-agent options.
Tigers: The Tigers need bullpen help, and if Kenny Rogers doesn't return, they'll need another starting pitcher, but they are more likely to fill their needs through trades rather than the free-agent market, which is thin on pitching this year.
Twins: They'll need a center fielder and a starter if they don't re-sign Torii Hunter and Carlos Silva. The Twins are also looking for a corner outfielder, a third baseman and a power hitter. They have prospects to trade and might be convinced to move Johan Santana or Joe Nathan for the right price.
White Sox: The White Sox addressed one area by re-signing shortstop Juan Uribe, and now they will focus on upgrading the bullpen and center field.
Angels: The Angels are looking for a power hitter for the left side of the infield and have expressed interest in Alex Rodriguez; they're also seeking another starting pitcher.
Athletics: The A's have been busy trying to fill their many needs, which include a right-handed-hitting corner outfielder, starting pitcher, shortstop, backup third baseman and bullpen help, and they will consider trading some of their pitching (perhaps Joe Blanton or Rich Harden) or some of their bigger contract commitments (Mark Kotsay and/or Eric Chavez?) to address those needs.
Mariners: Seattle needs a new right-handed setup man now that Brandon Morrow is moving to the rotation, and the Mariners are also on the lookout for a No. 2 or 3 starter and a left-handed bat off the bench.
Rangers: Teams are calling about Blalock, but the Rangers aren't likely to deal him. The Rangers are also looking for bullpen help with Eric Gagne and Kerry Wood (a native Texan) on their radar.
Braves: Replacing free-agent center fielder Andruw Jones is the priority, and the Braves are also hunting for another lefty reliever and bench help and might part with Kelly Johnson, Chuck James or Scott Thorman if they can't find what they need on the free-agent market.
Marlins: The Marlins' current needs are a starting pitcher, an everyday catcher and a center fielder -- though their picture could change considerably if another team blows them away with an offer for third baseman Miguel Cabrera or left-hander Dontrelle Willis.
Mets: They'd like to re-sign free agents Tom Glavine, Luis Castillo and Paul Lo Duca, and are eyeing other targets, including Jorge Posada, in case they don't.
Nationals: Center field, starting pitching and leadoff hitter, in that order, are the Nats' biggest needs, and while they will go after top free agents like Torii Hunter and Aaron Rowand, they also have players they would be willing to deal in Chad Cordero, Felipe Lopez, Ryan Church and Nook Logan.
Phillies: In getting Brad Lidge in a trade with Houston, the Phillies will move Brett Myers into the rotation to fill a need there. Now are looking at third base upgrades and center field options in case they can't re-sign Rowand.
Astros: Having settled their outfield for 2008 with the trade with the Phillies that brought Michael Bourn, the Astros now must find a closer, bullpen help, another starter and perhaps a second baseman. They have already contacted the agents for free agents Glavine, Jon Lieber, Francisco Cordero, Scott Linebrink, Jeremy Affeldt and Kaz Matsui.
Brewers: Milwaukee needs a corner outfielder and will also be looking for bullpen help if free agents Cordero and Linebrink do not return.
Cardinals: The Cardinals are looking for starting pitching and will need a shortstop if David Eckstein departs via free agency, but they don't have much in the way of trade bait and may fill their needs via the free-agent market.
Cubs: The Cubs would love to add a left-handed power bat -- preferably a right fielder -- and a starting pitcher, and if they can't find answers on the free-agent market, they might trade Matt Murton, Ronny Cedeno or prospects to fill the gaps.
Pirates: The Pirates are seeking to restock the system and might be willing to part with Jason Bay, Salomon Torres, Jose Bautista and/or Ryan Doumit for the right offer.
Reds: Only two rotation spots (Aaron Harang and Bronson Arroyo) are set, and the bullpen had the NL's worst ERA, so the Reds are looking hard for arms this winter and have outfield depth to deal.
Diamondbacks: The defending division champs are looking for a starter and bullpen help and have the prospects and available veterans to make them likely trade partners for a number of teams.
Dodgers: An uncertain personnel picture, considering the health questions of Jason Schmidt and Randy Wolf and the payroll if the Dodgers go after Rodriguez, and yet the Dodgers have talented veterans and prospects to deal and thus the flexibility to fill their holes any number of ways.
Giants: Few teams have as many attractive young arms as the Giants, and considering they must upgrade their offense for the start of the post-Bonds era, this is a team to keep an eye on this winter.
Padres: Second base, center field, back end of the rotation and bench help, the Padres have numerous needs and some organizational depth to use as trade fodder to fill them.
Rockies: The NL champs could lose second baseman Matsui and catcher Yorvit Torrealba to free agency, but in any case are looking for bullpen help and at least one starting pitcher.
