Miguel Castro isn't the only young reliever who is getting a higher profile early in the season. His roommate, Roberto Osuna, also is going to be pitching in high-leverage situations. He likely will find himself in a set-up role in the seventh or eighth inning.

"We're going to have to use him," manager John Gibbons said. "These are our guys. And we have to find out about the other (relievers). We had a chance to put some other guys in (Wednesday) but (Aaron) Loup and (Brett) Cecil are our reliable guys that we know a lot about. My thought was that if we don't get through the eighth inning, there wasn't going to be a ninth. And there wasn't a ninth."

Staked to a 3-1 lead, Loup came in to start the eighth and gave up a bloop single, a solid single and then hit Yankee Brett Gardner to load the bases with nobody out. Cecil came in and wild-pitched in one run, hit a man to force in another and then a grounder bounced off his wrist that scored another run.

Osuna came into the inning with one out and struck out Alex Rodriguez before getting a routine fly ball by Stephen Drew.

"With our rotation, the bullpen is going to be very valuable considering we don't have a lot of guys who you can expect to go eight innings or a complete game," Gibbons said. "(Daniel) Norris could turn into one of those guys. Maybe (Aaron) Sanchez but he tends to throw a lot of pitches. We're going to have to lean pretty heavily on our bullpen.

"We'd love to have somebody (in the closer role) so we could define the roles. But we're still trying to figure some things out. Normally, nine out of 10 times, we would shut that game down last night. It just didn't happen. The hit batters, the wild pitches, that's not normal."

"Generally teams have that bona fide proven guy and they just work backwards from there. But if teams with good closers don't have a quality set-up guy, then that guy isn't as good either. You don't win without a good bullpen nowadays."
