One starter's as good as the next (corrected)

The Twins rotation has been a shambles all month, and it got a bit more piecemeal Monday when Phil Hughes was sent back to the hotel with a fever and the flu. Tommy Milone started and got 17 outs (and his ninth win).

Milone's ERA stands now at 4.04. The Twins have six pitchers with at least 16 starts and 100 innings this year, and their ERAs are strikingly similar, with Hughes a bit out of step from the rest:

• Kyle Gibson (31 starts, 188.2 innings): 3.96
• Mike Pelfrey (29 starts, 163 innings): 4.09
• Hughes (24 starts, 154.1 innings): 4.43
• Milone (22 starts, 122.2 innings): 4.05
• Trevor May (16 starts, 113 innings): 4.06
• Ervin Santana (16 starts, 101 innings): 4.10

For that matter, Tyler Duffey and Ricky Nolasco have combined for 16 starts (but just 84.1 innings). Their combined ERA: 4.06.
