ARLINGTON, Texas -- RHP Mark Hamburger and LHP Michael Kirkman won't be on the ALDS playoff roster. But that doesn't mean they couldn't factor into future plans.
Hamburger and Kirkman were sent to the Arizona Instructional League on Thursday so they can stay sharp in case they are needed for the ALCS or World Series.
That's not unusual. Mark Lowe, who was injured much of last year, pitched on his own and eventually made the 2010 World Series roster in the bullpen.
RHP Merkin Valdez went home to the Dominican Republic.
The Rangers have until 9 a.m. Friday to set the playoff roster.
