Yankees manager Aaron Boone indicated Monday that Marinaccio has an "excellent shot" of making the Opening Day roster, Bryan Hoch of MLB.com reports.
Marinaccio has given up five runs over 4.2 innings this spring, but none of those runs have been earned. He has allowed only three hits while posting a 4:2 K:BB. The right-hander registered a 2.36 ERA, 0.99 WHIP and 41:8 K:BB across 26.2 innings at the Triple-A level last season.
