Peralta might not like his chances with his shoulder.
Calhoun has had that one down year over the past 6. He's been consistently better, but Peralta has had slightly higher highs.
Calhoun 6YR - 3.4, 3.2, 3.5, 2.1, 0, 2.5
Peralta 6YR - 1, 3.9, 0.3, 1.9, 3.9, 1.7
So 4 of the past 6 years Calhoun has out produced Peralta, and 3 out of the last 4.
