Well, I don't agree. We lost the game because of the 5 run 7th inning, which Kike had nothing to do with.
As for the semi-miraculous 7th and 9th innings by the Sox hitters, they were largely due to that 8-0 lead which brought in less than stellar relievers by the Reds--Cruz ERA 7.47 and Salazar ERA 16.20. When Lively left the game with 2 outs in the 6th and just a 3-0 lead, the reliever was Young, ERA 2.91. He got the third out in the 6th.
Then came the 5 run 7th (with Rodriguez on the mound for the Sox) by the Reds, the 8-0 lead, and the decision not to bring Young back to pitch the 7th. So Cruz came in and gave up 3 runs.
With the score now 8-3, with the Reds firmly in control, Sherriff pitched the 8th for the Sox and gave up the 9th and winning run.
And, with the score now 9-3, Salazar got to pitch to six Sox hitters, five of whom scored, in the 9th before Diaz came on.
As for Kike's error, too bad. Errors happen. My guess is that, because he and Valdez are slow turning double plays, he rushed his throw and missed.
And to me the bigger error was by Cora, who sent Rodriguez out to pitch the 7th with the Sox down 3-0. He clearly assumed the Sox would not score any runs in this game.
