Instead, the Padres went with two long relievers -- rookie Donn Roach and Tim Stauffer, the longest tenured Padre.
What really wasn't a consideration in February has evolved into a situation where Black could see two long relievers in the bullpen the rest of the season.
"I think so, yes," Black said.
Roach has a 2.57 ERA in 12 appearances this season and 21 innings. Eight of his 12 outings have seen him throw more than one inning. Stauffer has a 2.30 ERA in 11 appearances and 15 2/3 innings. He has thrown more than one inning in five of his 11 outings.
The Padres haven't always needed length from the bullpen this season, but Roach and Stauffer have certainly provided it -- with good results -- when called upon.
"It's a little bit comforting because you can use those two guys each and every night and you can space them out where you're never worried about length on any given night," Black said. "With Donn, even though he's been a Minor League starter, his arm is resilient. He's the type of pitcher who can develop into a resilient reliever.
"Stauffer has shown his ability to pitch out the pen and appear in multiple occasions in a given week."
As it stands, Alex Torres is the lone lefty in the bullpen, but because his stuff plays well against righties and the fact that Joaquin Benoit and closer Huston Street have fared well against lefties were other reasons as to why Black didn't see the need to add Schuster or Sipp.
"For me, it starts with who you feel comfortable with at the back end," Black said. "Our comfort level with Huston, Joaquin, Nick and Dale against either left- or right-handed hitters, that sets you up for the last three innings."
