We're going division by division to look at what each team needs to do at the trade deadline and what may actually happen. As always, you can keep up with the latest trade talk at Rumor Central.
Biggest needs: Right now the Cubs have enjoyed some recent success, sporting a four-game win streak that included a sweep over the defending champion Boston Red Sox. However, it’s important to remember where this team is in the rebuilding process. Right now their biggest need is minor league talent, regardless of position, but with an emphasis on near major league-ready starting pitching. They didn't get that with Addison Russell, the 20-year-old shortstop in Double-A, but he was too talented to pass up.
Other possible trade chips: With the blockbuster deal with the A's, the Cubs' available pieces have been considerably depleted. There are still names on the roster that can be had, but they aren't impact players. Guys like Nate Schierholtz, Darwin Barney and Carlos Villanueva are all available, but all figure to be role players designed to help a team fill out the back part of a roster.
The future: The Cubs now have a logjam in the infield, with Starlin Castro, Javier Baez and Russell all capable of playing shortstop. You can eventually move one to second base and one to third, but Kris Bryant is also there at third. Since being drafted with the fourth overall pick in the 2013 draft, Bryant has been a freak of nature with the bat and has accelerated quickly through the system. The rise has been so fast and the success so big (.357, 29 home runs between Double-A and Triple-A) that a lot of Cub fans have begun to wonder if Bryant could see Wrigley this season. It will be interesting to see how all this works itself out and if Baez or Castro will eventually be used to acquire pitching.

Biggest needs: The Reds are tenth in the National League in runs scored, so upgrading the offense should be the first priority for GM Walt Jocketty. Shortstop has been the least productive position, but at least Zack Cozart has been playing elite defense. Cincinnati would be better served trying to land a left fielder to replace the three-headed Ryan Ludwick/ Chris Heisey/ Skip Schumaker combination. The Reds also need to find an effective relief pitcher or two, as the bullpen has been one of the worst in the league, by almost any measure.
That prospect everyone will want but the Reds won’t want to trade: RHP Ben Lively tore through the California League before his promotion to Double-A Pensacola, posting a 10-1 record with a 2.28 ERA, 95 strikeouts, and only 16 walks in 13 starts. He has a live arm, and stands a good chance of competing for a spot in Cincinnati's rotation at some point in 2015.
Likely scenario: Seth Smith, an impending free agent, would look good in red and white, but it has been a long time since Jocketty took any direct action to improve the Reds by bringing in real talent from outside the organization. The most likely scenario, frankly, is that budget constraints and lack of trade bait cause him to continue sitting on his hands. Look for the Reds to seek to land a set-up reliever, possibly a lefty in light of Sean Marshall's continuing injury problems.

Status: Trying to lock up the NL Central.
Biggest needs: The Brewers opened play on Saturday with a four-game lead over the Cardinals in the NL Central, which was tied for the largest lead in any division. They've done it by getting contributions from up and down the roster, so there really aren't a lot of big holes to fill here. The main areas of need are the bench, specifically a left-handed power bat who can play first base or a corner outfield spot and a utility infielder who can play short and third. They could also possibly use a right-handed reliever for setup.
The untouchables: The Brewers' much-maligned farm system has taken a significant step forward this year, headlined by the breakout performance of starter Jimmy Nelson in Triple-A. Down in A-ball, OF Tyrone Taylor, SS Orlando Arcia and C Clint Coulter are having the kinds of seasons that would make them attractive players to ask for in trade. That being said, it's hard to imagine them giving up any of these players to fill these second- and third-tier needs the team has to fill.
What probably won't happen ... but might: Brewers owner Mark Attanasio and general manager Doug Melvin haven't been shy about making big, splashy moves when contending in the past, so we shouldn't completely rule out the earth-shattering blockbuster. The Brewers did send a scout to watch a recent David Price start, and he would give them the obvious ace that their more balanced rotation lacks. It's not likely because they could easily be outbid by teams with better systems and they don't really need to do it, but don't rule it out.
What probably will happen: Melvin has talked quite a bit in the local media about his desire to add a right-handed reliever who can pitch late in games, so unless either Tyler Thornburg or Jim Henderson get healthy over the next month something will probably happen on this front. Despite some recent protestations from Melvin that they don't have big needs for bats, it's hard to see them standing completely pat without adding at least one player who can hit off the bench.

Status: After a slow start, they're back in it. Since May, the Pirates are tied with the A's for the best record in the majors.
Biggest needs: Starting rotation. The rotation has been better since May 2, but even then the 3.90 ERA is just ninth in the National League. Among position players, first base remains the biggest hole, as Pirates first basemen (mostly Ike Davis) have been worth 1.4 wins below average. They already made the Jason Grilli-Ernesto Frieri trade but could use another bullpen arm for depth.
Possible trade targets: SP A.J. Burnett ($15 million mutual option or $7.5 million player option for 2015); 1B Justin Morneau ($6.75 million in 2015); SP Jon Lester (free agent); SP David Price (under team control for one more season); RP Chad Qualls ($3 million in 2015); RP Tony Sipp.
Likely scenario: Jeff Locke and Vance Worley have helped solidify the rotation of late with Francisco Liriano on the DL, but you probably can't rely on those two to keep this up (although Locke's walk rate has been much improved from last season). The rotation is OK enough that it makes sense for the Pirates to only go after one of the big guns -- which means Price or Lester, now that the Cubs traded Jeff Samardzija and Jason Hammel. The Pirates have pitching prospects like Nick Kingham and Tyler Glasnow that are certainly interesting, but the Pirates have to get closer to the Brewers before management would consider such a big trade and added salary. As for first base, maybe Clint Hurdle should see if super utility guy Josh Harrison could handle the position to at least platoon with Davis.
In the end, the Pirates probably stick with what they have and hope Liriano and Gerrit Cole have better second halves and that one of Locke or Worley manages to hold his own.

Status: Chasing the Brewers while in the thick of the wild-card race.
Biggest needs: It's easy to point to the rotation now that Michael Wacha and Jaime Garcia are on the disabled list, but the offense is just 13th in the NL in runs while ranking last in home runs. Second base has been a disaster, with a combined line of .201/.268/.260.
The big chip: OF Oscar Taveras remains one of baseball's top prospects, despite a lackluster .196 mark in 15 games with the Cardinals earlier this season (he's hit .318/.370/.502 in Triple-A).
Likely scenario: The Cardinals and Dodgers remain the two teams most often tied to Price, largely because they have quality and depth in the farm system to deal from. A lot depends on the prognosis of Wacha; if he can't come back, the Cardinals are more likely to go after Price or maybe Lester if he becomes available. That said, Kolten Wong and Mark Ellis haven't produced at second and that could be filled much easier (Matt Carpenter can always move back there if they go after a third baseman like Prado). Either way, considering the ages of guys like Yadier Molina, Matt Holliday, Adam Wainwright and Allen Craig, there's some imperative for St. Louis to make a deal this year.
