Kirby threw one inning 2 weeks ago, JR was off last week, so this was his second appearance. JR has 4 or 5 games at its spring break tourney in SC next week, so I would guess he'll be stretched out to 4 or more innings in one of those games. The alternative would be to use him in relief and try to get two stints out of him. Not sure how the coaches intend to work it.
