Bruney, Capps, Clippard, Walker, Bergmann, Stammen, Speier, Batista would all likely be ahead of him on the depth chart... and that's just RHP.
If he could fill a role, great.
His K/BB would not be that high in the pros. He's projected at a low 1.38 K/BB.
Of the 9 Nats pitchers that threw at least 50 innings last year, Gambino would be 7th on that list.
Projections - 3-4, 4.50 ERA, 45 games, 64 IP, 64 H, 36 K/26 BB, 1.41 WHIP, 5.16 FIP and these are the favorable projections.
