"[We] gave him some clearance from his last start, so making sure he was healthy and ready to go before we sent Quack down," Green said. "Jarred slides back into that [long-relief] role and hopefully maintains health throughout the rest of the season. [There's a] possibility he starts at some point in time again."
Quackenbush was 0-0 with a 3.68 ERA in six appearances. This marks the fourth time he has been optioned to Triple-A since March 29. He is on the move again because he has Minor League options.
"Every organization has guys that are in that boat," Green said. "It's not the most desired role whatsoever for a player. They want to be on the Major League club, and they want to be with the team consistently, but those guys that go up and down throughout the course of the season are very, very instrumental in having successful baseball seasons, so it's a hugely important role.
"I'm sure it's tiring at times going back and forth, and I know Quack desires to be with us and we think he's pitched well when he's been with us. I have every expectation we'll see him again sometime soon."
• Infielder Allen Cordoba was out of the Padres starting lineup Sunday due to hamstring tenderness and the team playing a day game after a night game, but he is available to play, Green said. "We took the cautious route with him today," Green said. "Otherwise, he would've been back in the lineup for sure."
• Right-hander Kyle Lloyd threw the Padres organization's first no-hitter since 2014 on Saturday for Double-A San Antonio. The lone baserunners were via a walk in the second inning and a wild pitch on a strikeout in the fifth inning. "He's a guy I've heard a lot about over the last year or so, a guy who really knows how to pitch, executes well, and it's not overpowering velocity but can flat pitch," Green said. "It's an exciting thing."
