Chicago White Sox — With the White Sox languishing in the AL Central basement, Addison Reed could be traded if another team makes a great offer. If Reed does move, he’ll either take on a setup role (drastically decreasing his value) or close for a better team (mildly increasing it). On balance, we think the rest of this season will see a slight regression in Reed’s worth to you. Meanwhile, if Reed is traded, Matt Lindstrom will probably be the White Sox pitcher who benefits most. Jesse Crain could be in the mix also, once he returns from his injury, but (as noted in the link above) he’s even more likely to be flipped this month. BUY: Matt Lindstrom. SELL: Addison Reed.
Cleveland Indians — The Indians need to add a lefty arm and perhaps replace Vinnie Pestano, but Chris Perez and Cody Allen are pretty secure. BUY/SELL: None.
Detroit Tigers — Detroit is likely to trade for one or two relief pitchers; although it’s not yet clear whether they will replace Joaquin Benoit with a “proven closer” or simply reload with middle relief reinforcements, we think Benoit’s days as the closer in Comerica are numbered. SELL+: Joaquin Benoit.
Kansas City Royals — Although there’s a strong case that Kansas City should flip Greg Holland now, at the height of his value, the three years of team control remaining suggest that he’ll remain a Royal for a while. BUY/SELL: None.
Minnesota Twins — Glen Perkins is too good a closer to stay on this bad Minnesota team; if he’s traded, he’ll almost certainly be closing for a contender, while Ron Gardenhire goes to Jared (Burton) and dreams of someday getting a ring. BUY: Glen Perkins, Jared Burton.

Houston Astros — With Houston as bad as expected, Jose Veras is extremely likely to be traded this July — but he’ll probably move into a setup role wherever he ends up. Jose Cisnero is expected to succeed Veras, if necessary. BUY+: Jose Cisnero. SELL+: Jose Veras.
Los Angeles Angels — It’s been a disappointing year for the Angels and it’s unlikely that any exciting bullpen trade news will spark a second-half renaissance. BUY/SELL: None.
Oakland A’s — Oakland might add another arm in middle relief; they were chasing Matt Thornton before the Red Sox sealed that deal. With Grant Balfour facing free agency, though, don’t put it past Billy Beane to deal his All-Star closer, even with the A’s atop their division. BUY: Ryan Cook. SELL: Grant Balfour.
Seattle Mariners — Oliver Perez and Charlie Furbush are both attractive trade bait; Perez’s save chances are likely to drop off dramatically if (and when) he’s moved. Yoervis Medina could benefit as a result. BUY: Yoervis Medina. SELL+: Oliver Perez.
Texas Rangers — The Rangers are very happy with their deep bullpen; any trade they make will focus on their offense or starting rotation. BUY/SELL: None.
