Anderson, who was optioned to Reno following Tuesday's game, was able to be recalled before the minimum 10 days due to the injury. Hellickson, 28, is 9-8 with a 4.60 ERA (66 ER in 129.0 IP), .263 opponents average (134-for-509) and 107 strikeouts in 23 starts (11 quality) this season. Anderson, 27, is 5-5 with a 4.51 ERA (61 ER in 121.2 IP), .280 opponents average (130-for-465) and 84 strikeouts in 21 starts (10 quality) this season.
Well, that was quick. And a little strange, considering it's doubtful Hellickson will have done anything since the end of his last start, three days ago, to have aggravated the injury. I'm guessing it simply didn't recover fast enough for his next start which would have been Saturday, to be considered an option. Interesting how at the time, and after the game, it was described as "cramps" and "dehydration", and as recently as Tuesday was said to be "improved." However, he added ""Probably get a better idea tomorrow when I get on the mound," referring to his bullpen session yesterday; and it appears the results there may be what triggered the need for a move.
We still don't know at this point how the pitching order is going to shake down. Presuming Anderson takes his scheduled slot again, he'd pitch Sunday, and would then mean the team has a vacancy for Saturday's start, That could rule out Aaron Blair as a possible, since it would require him to pitch on short rest after his last appearance, on Tuesday for the Aces.
UPDATE. Looks like it'll be Randall Delgado who gets the spot start.
