While we can only surmise about the actual health of current players, we do know that Valdez and Garcia beat a Red Sox lineup twice each five months ago.
A lot can change by the Fall, two seasons after the Spring, including the condition of pitchers' arms. The White Sox, a step behind the Red Sox in offense all year, knocked around both Valdez and Garcia just last week.
Meanwhile the Boston batting order has definitely changed since Memorial Day. Some hitters have even morphed or peaked in October. For example, Verdugo has thrived in this postseason environment -- eight hits in five games, tied with Kike and Rafie with six RBIs, making big plays -- he stays in my lineup.
Of course, if a guy like Martin Perez makes the ALCS roster, it can only be because he threw the best of all Red Sox vs. Houston last June, with 7 2/3 shutout innings (pre-sticky stuff ban).
