Not a lot of history. Teheran faced the D-backs earlier this year, and gave up seven hits and two runs in six innings, striking out three and walking none. Unfortunately Eric Chavez owns two of those hits, and he remains on the DL. Of Diamondbacks who can actually play today, .240/.269/.280 figures, with Gerardo Parra leading the charge (2 for 5 with a double). Didi Gregorius drove in both runs in the previous meeting, and Pollock, Prado, and Pennington also got hits. Apparently, it helps to hit Teheran if your name begins with a plosive, preferably a p. Still, 26 plate appearances is a small sample size, and those figures are better than the figures against Strasburg I posted yesterday.
As would be expected, current Braves have faced Delgado even more rarely, with only 12 plate appearances. Jordan Schafer and Chris Johnson are the only players to get hits. I looked at a few minor league statistics, but couldn't find any additional plate appearances. I did see that Goldschmidt seemed to hit a home run off Delgado every game they faced each other in the Southern League.
I'm guessing Aaron Hill gets the day off today. He hasn't done particularly well against either of the other Braves' starters, and has never faced Teheran, but I think after extra innings he gets a break.
I'm going to be away from a computer tomorrow morning, so I may post statistics for tomorrow's game later today.
