Nicasio appears to be the odd man out of the rotation, if and when the Pirates promote one of their pitching prospects following the Super 2 arbitration date.
The righty holds a 6.75 ERA in May and has been outpitched by Jon Niese and Jeff Locke, both of whom were thought to be on the rotation bubble at one time or another. Nicasio registered a 3.86 ERA in 2015 as a reliever and Pittsburgh could use additional bullpen help. His fastball, which averaged 95.1 mph out of the pen last year, has dropped to 93.3 mph.
