IMO, you can only win the game you are currently playing , not tomorrow's or next week's. To me, Cora should have recognized that Rodriguez was having a bad night after 3 walks and a hit, prior to the Grand Slam. Maybe Cora was thinking it was 50-50 between a GIDP or just another walk then he makes a move to Sheriff . But maybe he should have thought that after 35 pitches with only 16 strikes, Rodriguez would try to push a strike over the plate and get bombed , which is what happened.
A statistically rare outcome but certainly possible, and those 4 runs, along with the ball Duran couldn't pull down in CF , resulting in a triple off Sheriff and a sac fly for the 9th run sunk the Sox 8 run outburst against the Reds lesser BP throwers.
So did Cora defer pulling Joely because he considered the game lost at 4-0 , due to dead bats in the 6th, or was he playing today's game vs the Reds saving ammo in the BP, OR was he actually preplaying the 4 game series with TB who waxed his team 4 straight a month and a half ago. Time to get the Sox act back together and win these next two.
