Olney: Buyers or sellers? These five teams need to decide now

Better than any of their peers, the good folks who run the Minnesota Twins’ front office have demonstrated how wrenching the decision to buy or sell can be. A year ago, they decided to be buyers, completing a trade for Jaime Garcia at a time when the Twins were 3½ games out of first place.

The Twins promptly went on a mini-losing streak and by July 30 — just six days later — Minnesota was seven games out of first place. Immediately, the Twins became sellers, flipping Garcia to the Yankees after only one start. But down the stretch, the Twins’ offense exploded, and Minnesota boat-raced its way into a playoff berth.
