The White Sox placed Lucas Giolito on the 10-day injured list, retroactive to September 1, due to a left hamstring strain this afternoon. It seems the move is mostly precautionary, as manager Tony La Russa told reporters (including Daryl Van Schouwen of the Chicago Sun-Times) that Giolito is scheduled to throw a bullpen session next Wednesday. The White Sox can afford to be especially cautious with even minor injuries for their top players, as they’re coasting to a division title and hoping to get everybody right for the postseason. Giolito has a 3.69 ERA/3.68 SIERA over 158 1/3 innings this season.
