The Minnesota Twins' Brian Duensing has become known as a "lefty specialist" for incredible effectiveness in key situations against lefties. As the midpoint of the the 2012 MLB season approaches, several teams should be looking to add Duensing to their roster.
Some of these teams are .500 clubs with poor pitching against left-handed batting. Others have beat-up pitching staffs that simply need to add a reliable LHP to their bullpen.
Whatever the case, Duensing's numbers could entice teams to pick him up this midseason. Currently, Duensing has an incredible .157 BAA against lefties with a modest 4.91 ERA (an overall ERA of 3.12 ERA).
