So, that's Hudson's return out of the way. Tonight isn't quite as exciting, but does mark Randall Delgado's return to the Diamondbacks' rotation.

| Randall Delgado - RHP | Ian Kennedy - RHP |
Tonight will be Delgado's third start of the season, all of them having come away from Chase Field. It's safe to say that the first two did not go too well. Over 7.1 innings of work, first in Colorado and then in San Francisco, Randall threw 7.1 innings of work, allowing sixteen hits, with an 11.05 ERA. Now, some of that is a hellacious .469 BABIP, especially with a line-drive rate of only 18%, but a K:BB ratio of 3:5 wasn't getting it done either. You won't last long in any major-league rotation when you are allowing close to three base-runners per inning, all told, and he'll certainly need to be much, much better tonight.
Since moving to the rotation, he has been... better in some ways. Over 37 games, he has thrown 52 innings, and held hitters to a .205 batting average, which is very good. However, there have still been too many walks, jacking the OBP against up to .307. Even so, a .655 OPS generally suggests a better ERA than the 5.19 which has resulted, perhaps implying he had bad luck with the runners left behind after he left the game. I haven't been able to find stats this year for "bequeathed runners", only inherited ones, but a quick check shows 7 of the 13 runs Delgado has given up in August, came when he was no longer on the mound. Should be much less an issue tonight.
