What Does Terry Collins Have Against Wilmer Flores?

It's become apparent that Mets manager Terry Collins is not a fan of shortstop Wilmer Flores and instead favors backup shortstop Ruben Tejada. Collins has taken multiple jabs at Flores and his offense and defense. Last season, after a game-winning grand slam against the Phillies, he tried to downplay it by saying it wasn't against Cliff Lee. TC continued to bench Flores for the majority of the season last year and give Tejada the majority of the starts. He only started Flores in September, where he put up solid offensive numbers. This season, Collins has showed skepticism of Flores and has questioned whether he can hit well enough or make enough defense plays to remain the starting shortstop. In tonight's game, against the Brewers, despite being the team's home run leader with 5, he decided to bat Flores 9th. Fortunately, Flores was able to prove Collins wrong by hitting a grand slam. After the game, Collins once again tried to jab at Flores by saying that he batted him 9th because he's not Giancarlo Stanton and that the bench was surprised that Flores came through. I found these comments to be very disrespectful, unprofessional, and demeaning. A manager should never make these kind of statements about his players. He should be praising them when they perform and try to boost their confidence, rather than disregard their accomplishments or make sarcastic comments. It's just not right and I wish Sandy Alderson and the Mets front office would try to hold Terry Collins accountable for his comments that try to belittle Wilmer Flores.
