Closing, shmosing. Ottavino almost gave the game away last night in the 8th inning right after the Sox tied it on the weak sac fly, and Ottavino is a very experienced and well paid reliever who overall has been good for the Sox bullpen this year.
My version of the 9th is that the Sox hitting, led by the bottom of the order, finally came through. Verdugo, Dalbec, and Chavis combined for 6 of the Sox 10 hits, and both Verdugo and Dalbec singled in the 9th. However, Green also K'd Vazquez (of course) and got Plawecki on a line out to Gardner in left. When Hernandez, the Sox hottest hitter right now, came to bat the Sox had two on and two out, and Hernandez simply hammered that fastball off the wall--which Gardner couldn't handle so Duran, pinch-running, was able to score from 1b.
So, me, I think the Sox earned that tie in the 9th and Green didn't fold.
As for Kriske, he was in there for the same reason Andriese pitched the 12th with a 2 run lead three weeks ago at Oakland. The four wild pitches weren't just because he was nervous, they were also the result of a catcher who couldn't field them and a catcher and manager and pitching coach who allowed Kriske to keep throwing those curves despite the fact that he K'd JDM on fastballs.
Back to my point. I think the 7th and 8th innings are often just as important as the 9th or 10th in terms of game outcomes, and that's why winning teams usually have well-stocked bullpens. Goodness knows that, as good as Barnes has been this year, there have many games in which the earlier Sox relievers laid the groundwork for Barnes to get his save. Indeed, last night Taylor, Hernandez, and Rios combined for 3.1 scoreless innings. Only Ottavino stumbled, maybe because this was his 3d appearance in 3 games in 3 days.
