Burnett hopes to avoid a rehab start, and Hurdle hasn't given any thought as to whether or not Burnett will need one.
But Hurdle said that traditionally, players who return from rehab starts are sharper than those who skip them. Burnett, however, didn't injure his arm.
"We haven't given it any thought other than taking it one day at a time," Hurdle said. "He has his own personal feelings, that he's going to continue to do the work he needs to do.
"We'll talk. That's what we'll continue to do."
