Three wins down and eight to go for the Red Sox to capture their fourth World Series title since 2004. The next four will be the most difficult facing the defending World Series champion Houston Astros. The Sox and Houston combined for 211 wins during the regular campaign, which is an all-time record high for post season opponents. The Sox and the Astros met in a Division Series last year with Houston winning in four. The only Sox victory came in Game Three at Fenway when Hanley Ramirez went four for four and David Price worked four scoreless innings out of the bullpen. Both of these teams are better than they were last season with the Sox’ addition of J.D. Martinez and Houston’s acquisition of righthander Gerrit Cole. It’s baseball’s best in the A.L.C.S. with home field advantage to the Red Sox. Boston in seven.
