Appropriately--or so I think--there aren't many slings and arrows directed at Cora on this thread. Yes, during games, but that is usually reactionary.
Last night I thought Cora handled a tough situation--losing starter Price in the first inning--pretty darn well. He relied on the bullpen and they pretty much came through and didn't use his best guys at that. Also interesting is that he started Vazquez at DH, then pinch-hit for Leon, moved Vazquez to catcher, and thereafter had to pinch-hit for the pitcher, which proved not to be a problem.
The Sox lost in my opinion because, despite a fantastic rally by Devers, Chavis, JBJ, and the huge single by JBJ, the top of the order--Beni and Moreland--crapped out. And of course Barnes picked this outing to abase himself--lead off double, walk, walk, and hard hit single and no outs.
The manager is ultimately responsible for all wins and losses, but this year the hitting, pitching, and especially defense are all down from last year.
