Allen is lined up to start Thursday's pre-season game against Minnesota, according to the St. Louis Post-Dispatch. Allen and nominal starter Brian Elliott are alternating starts so far in the pre-season, a pattern that is likely to hold into the regular season the Blues appear poised to split their starts pretty evenly. As the rookie, Allen is likely to end up on the short end of the split, but his status as a legit top prospect (and Elliott's historical streakiness) could play into how the starts get divided up as the year goes on.
