Not necessarily.
If they extend Ranger, they'll have 4 starters locked up the next 3 seasons, plus Walker for 2, plus Phillips.
With Painter and Abel starting the season in Lehigh, with Mercado and McGarry in the pen.
That allows you to go with Cabrera, Aldegheri, McGowan, Castellanos, and possibly Klassen/Steward at Reading.
Then you load up the Lehigh pitching staff with veteran retreads and TJ recoveries.
