Nicasio is a likely candidate to fill in for Carlos Frias (back) on Monday against the Phillies, MLB.com's Ken Gurnick reports. Nicasio already has one start under his belt this season, and owns a formidable 2.18 ERA over 33 innings. With Frias landing on the disabled list, he'll potentially serve as a short-term solution, but would likely return to long relief afterwards.
