The Phillies hope they addressed any needed bullpen improvement through the improvement of their rotation. The philosophy is grounded in logic.
With four starters who routinely pitch into the seventh inning - do we really need to list their names? - the back-end trio of Brad Lidge, Ryan Madson and Jose Contreras should suffice.
In fact, the strength of the rotation could prompt the Phillies to carry six relievers instead of the customary seven.
"I hope it's a discussion," general manager Ruben Amaro Jr. said earlier this week. "That will mean that we're healthy going into the season. I can't say it's a definite. It's a debate we'll have."
Things could get interesting in the event of an injury, either to the aforementioned relievers or one of the front four starters. The Phillies have decided to sacrifice depth in their bullpen for depth in their rotation, at least in terms of their allocation of payroll space.
That's why it will be worth watching the performance of the slew of young relievers in camp this spring.
Lefty Antonio Bastardo has a huge upside but hasn't had a chance to pitch consistently at the big-league level. He appeared in 25 games last season, registering an impressive 26 strikeouts in 18 2/3 innings. But he also walked nine, hit two batters and allowed nine earned runs.
Veteran lefty J.C. Romero is the only experienced southpaw on the roster, and he was re-signed only after an agreement with free-agent Dennys Reyes fell through.
Amaro said righthanders Kyle Kendrick and Vance Worley will compete to fill the role that was previously held by Durbin, who was used primarily in multiple-innings situations but also could pitch in the late innings of tight games. He said that neither pitcher is more suited for a relief role than the other.
"Both of these guys can be multiple-innings guys," Amaro said.
