I believe Holliday makes the opening day roster, he was rushed through the minor leagues with a purpose....His left handed bat to ball skills out trumps Westburg or Ortiz as righties at Camden Yards so yes he's needed to replace Frazier as a left hand hitting middle infielder
You must use the imperial « we » because the collective « we » definitely didn’t see it coming. His starts from April thru June were collectively awful. Congrats on your perspicacity. Most of us chalked up the Cardinals start as one of those things that sometimes happens before there’s a book on the new guy.
