Valetine made some mistakes early, but for the last couple of months he has made very few errors. He has fashioned a pretty good bullpen out of second rate has been pitchers by carefully choosing appropriate roles for them after losing his closer. He has been quick to remove struggling pitchers instead of sticking with a pitcher until we were hopelessly far behind, a favorite trick of Francona. He has had that relief pitcher ready to go. Valentine has been much better than Francona at utilizing all of the offensive weapons at his disposal, including bunts and suicide squeezes. Not sure what Francona even knows what the word means, even now. Valentine has utilized the pinch hitter much more effectively than Francona ever did. He has emphasized hustle and although the player execution has not been 100% accurate, at least he made them practice it more than the previous manager. Finally (for now), he is up there cheering for the players in the dugout whereas Francona hung out near the spitoon all game long, barely paying attention to the game, seemingly. Where Valentine could improve nowadays is by not allowing players to run the show as much (he should be disciplining insubordinate players, no matter how much money they make) and he should not be penciling into the lineup stiffs like Lillibridge-EVER. They should ride the pine until the FO realizes that the man who makes out the lineup card is not going to play incompetent ballplayers.
Overall, Valentine has not been perfect, but he is a refreshing improvement over Terry Francona.
