With four relievers under the age of 27, Leyland is hoping to see more consistency.
"It's not like we have an established guy down there like a [Octavio] Dotel that has been through the wars and you pretty much know what you are going to get," Leyland said. "With kids and grandkids, we don't know."
Smyly is the only reliever with more than six innings on the mound to have an ERA of under 3.00 against hitters from both sides of the plate. He has thrived in the bullpen, dropping his ERA of 4.30 against right-handed hitters last year as a starter to 2.84 this season. He has held right-handed hitters to a .260 batting average, and left-handed hitters have fared much worse, mustering only a .100 batting average against him.
"That's why I keep stressing that a lefty has to get a righty out up here," Leyland said, "and a righty has to get a lefty out. If they can't, that makes it difficult."
Although Coke works to cut down the .343 batting average that right-handed hitters have against him, Leyland says he is more than just a lefty-lefty specialist.
"Cokey should be," Leyland said, "because he has the changeup and plenty enough fastball with a breaking ball to get a right-hander out."
