Gotta bring in the lefty, right?
Not when the lefty is Joely Rodriguez and his lifetime line against same-handed batters is .417/1.101 in 29 plate appearances and only 2 K.
Stay with the power armed righty with a chip on his shoulder (Ramos). Using a lefty for the sake of using a lefty is being too cute with your pitching staff. It might make Tony LaRussa proud, but the outcome was predictably disastrous (2-run homerun, Mets went onto win the game 4-3).
Ramos career against LHB - .244/.774, which isn't ideal, but is a helluva lot better than Rodriguez's.
Joaquin Benoit career against LHB - .215/664, would have been the best choice for a 4-out save, but I'd have just rolled the dice with Ramos.
Mackanin and Co. need to learn how to manage a pitching staff. This has been my major complain against him since he took over as manager. Well, that and his unwarranted loyalty to players despite better choices (Howard, Jeanmar, Chooch).
