As the Twins stumble toward a third consecutive 90-loss season next week's trade deadline is an opportunity to acquire young talent to aid the ongoing rebuilding effort. But will any of the Twins' obvious trade candidates be in enough demand to actually fetch significant long-term help? And does it make sense for the Twins to shop some not-so-obvious veterans in an effort to make a bigger splash? Here's my view of the players they might deal between now and July 31.

Justin Morneau: Sadly, at this point Morneau is little more than a recognizable name with an MVP trophy and a big salary. He hasn't been the same since suffering a concussion in mid-2010, hitting just .258/.319/.401 in 295 games over the past three seasons. This year he's been healthy after dealing with an assortment of major injuries in addition to the concussion, but his power has vanished and his .726 OPS is 50 points below the MLB average for first basemen.

Contending teams looking to add a left-handed veteran bat cheaply may have some interest, but even if the Twins are willing to cover the remaining $6 million on Morneau's contract they aren't going to get much for the 32-year-old impending free agent. He hasn't been an above-average first baseman since the concussion and has played poorly enough that draft pick compensation is no longer a realistic option, so it's either let him walk for nothing or settle for a modest return.

Glen Perkins: Trading relievers when their value is high usually makes sense because their role only involves throwing 60-70 innings per season and they often burn out sooner than expected. Toss in the "proven closer" aspect potentially inflating Perkins' perceived value a la Matt Capps and the Twins would be making a mistake if they didn't listen to offers. With that said, he's not an example of the closer role making a mediocre reliever look like a great one.

Perkins is legitimately great, with a 2.37 ERA and 194 strikeouts in 171 innings since moving to the bullpen full time, and because the Twins signed him before he became a "proven closer" he's priced more like a setup man. He's under team control at reasonable salaries through 2016, so even setting aside the fact that he's a native Minnesotan and fan favorite there's no reason to trade Perkins now unless they get big-time value back.

Jared Burton: Everything about trading relievers with their value high applies to Burton too, but like Perkins he's under team control for reasonable salaries: $3.5 million in 2014 and $3.6 million in 2015. Burton is also two years older than Perkins and has a lengthy injury history that allowed the Twins to acquire him cheaply in the first place, so there should be quite a bit more motivation to shop the 32-year-old around now.

Burton has a 2.71 ERA and 95-to-34 strikeout-to-walk ratio in 106 innings for the Twins and even after going through a rough patch recently his overall numbers this season remain late inning-caliber. If the Twins can get a solid position player prospect or a young pitcher with some upside for Burton they should absolutely consider it strongly, but he's cheap enough, good enough, and signed for long enough to hang onto unless the market is a decent one.

Mike Pelfrey: His early work coming back from Tommy John elbow surgery was ugly, but Pelfrey has looked much better recently and more or less resembles his pre-surgery self. Of course, he wasn't all that good before going under the knife, posting a 4.45 ERA and 5.0 strikeouts per nine innings in 97 starts for the Mets from 2009-2011. Since a brutal April he's started 13 games with a 4.38 ERA and 6.0 strikeouts per nine innings.

Pelfrey was signed in the hopes that he could eat innings for a rebuilt rotation, but he's gone more than six innings just twice in 18 starts and with the Twins already out of contention a 29-year-old back-of-the-rotation starter on a one-year contract carries even less value than before. He's owed about $1.5 million for the rest of the season, so teams that miss out on bigger targets might view him as an inexpensive fallback option.

Kevin Correia: Correia has been as advertised, posting a 4.17 ERA compared to the AL average of 4.05 while striking out just 5.0 batters per nine innings and serving up 18 homers in 19 starts. He hasn't been horrible, but he certainly hasn't been an asset and because the Twins felt the need to give him a two-year contract at age 32 he's owed $2 million for the rest of this season and $5 million next year.

None of their young rotation options have established themselves as quality big leaguers yet, so bringing back Correia for 2014 wouldn't be a terrible idea. However, there was nothing separating him from the various mediocre starters who signed one-year deals this offseason and the same type of starters will be available again this winter, so if the Twins can get a mid-level prospect in return while wiping his salary off the books that sounds pretty good.

Brian Duensing: After repeatedly flopping as a starter the plan was for Duensing to move back into the bullpen and rediscover his previous success as a reliever. Instead he's mostly struggled, against both righties and lefties, although his secondary numbers versus left-handed bats remain promising. Duensing is a decent middle reliever, but the need to be sheltered from right-handed power hitters will always limit his value.

Beyond that he's 30 years old and being paid $1.3 million this season, with the arbitration process all but assuring him a raise for 2014. If the Twins think he can bounce back to his pre-2013 relief work then Duensing would be worth keeping around for next season and they also have him under team control for 2015, but he's no longer a bargain and no longer has any real upside. If a team in need of left-handed bullpen help is willing to part with a decent prospect they should take it.

Ryan Doumit: When the Twins signed Doumit to a two-year, $7 million contract extension in the middle of last season it seemed like a fair price for an above-average hitter with some defensive versatility and one of the talking points was that the deal would make him easy to trade if needed. Instead he's hit just .237/.297/.388 in 87 games for the worst production of his career at age 32 and has struggled defensively as a catcher and corner outfielder.

Doumit is owed about $1.5 million for the rest of this season and $3.5 million next season, so his contract is hardly an albatross. Still, he was never perceived as being especially valuable to begin with thanks to his terrible defensive reputation behind the plate and Doumit's hitting has fallen off enough that trading him would probably be mostly about unloading the salary. He could be useful next season in a similar but reduced role if there's no market for him.

Trevor Plouffe: Plouffe is sort of the wild card in any trade speculation because he's 27 years old, making the minimum salary, and under team control through 2017. However, the Twins rightfully seem less than convinced that Plouffe's good but not great offense makes up for his awful defense at third base and 20-year-old stud prospect Miguel Sano will hopefully be ready to take over the position relatively soon anyway.

Plouffe could always slide across the diamond to first base, where his defense would be less of a negative and maybe even turn into a positive, but his .242/.305/.442 line at the plate since the beginning of last season would be below average among first basemen. On a good team Plouffe fits best as a part-time player who can fill in at a few positions and get most of his playing time versus left-handers, but if another team views him as an everyday asset the Twins should listen.

Josh Willingham: This time last season Willingham was in the middle of a career-year at age 33 and there were some trade rumors swirling, but the Twins opted against dealing him and then decided not to move him during the offseason either. It's impossible to say for certain what they could have gotten for Willingham in July or December, but whatever trade value he had is gone now and he'll be on the disabled list when the July 31 deadline passes.

Willingham had a strong April, but then hit .213/.338/.343 in 50 games from May 1 until the Twins finally shut him down in late June. In addition to the poor production at the plate he was also even worse than usual defensively in left field, limping around on what turned out to be a torn meniscus in his left knee. Willingham is due back in late August and it's possible the Twins could move him during the waiver trade period, but any chance of getting a significant return is long gone.

Jamey Carroll: Carroll went from useful, underrated role player to washed up in the blink of an eye, which is often what happens to 39-year-olds. His contract includes a $2 million team option or $250,000 buyout for 2014 that becomes a player option if he gets 401 plate appearances, but there's no chance of that happening. He's a goner anyway and might be headed for retirement, so if the Twins can save money or get a random minor leaguer in return it would make sense.
