Jameson Taillon joins the Pirates' rotation today, and despite Neal Huntington's protests to the contrary, he seems likely to stay. That means someone needs to go, and the widely held assumption is that Juan Nicasio will move to the bullpen. That might happen, but I'm not sure it should.
Nicasio is a frustrating starter. He throws two pitches about 95 percent of the time, which makes him vulnerable against lefties and over long stretches.
Still, he hasn't been bad. Including last night's strong performance, he's whiffed a batter per inning this season while walking a very reasonable 3.
