What I don’t understand about bringing Foley in for the 7th is that, I think anyway, he is the best reliever? So, he’s being brought in to face 5-6-7 when the game is going to come around to 1-2-3-4 even if the relief is perfect though the 7th and 8th. I don’t think your “closer” needs to be only used in the 9th.
I can more understand bringing him in there if the top of the lineup were due up in the 7th and 8th innings, and Foley was to get that string of hitters. I would think bridging until then with Foley would have been what happened today.
Besides that, Olson was doing fine. I think his only stressful inning was due to Ibanez’ error? I know he was up against 90, but if it’s a relatively unstressful 90, let him pitch. Have the bullpen ready, don’t let him face the tying run.
