"I haven't felt it in a long time, but it's my [swing], yeah," Venable said.
"I was messing with some stuff that felt good, and then found something about four days ago that felt right."
The Padres optioned Venable to Tucson on May 23, and after 14 Minor League games, he returned to San Diego on Thursday.
Venable hit .529, getting nine hits in 17 at-bats in his last four games -- with two doubles, one home run and six RBIs, while scoring five runs.
"He was hitting the ball with authority. Even some of the outs he made -- according to our people -- were hard-hit outs," Padres manager Bud Black said.
When Venable was optioned to Tucson, he was hitting .224.
Venable flew into San Diego on Thursday morning, and said he's ready to help in whatever way he can.
"No one wants to get sent down," Venable said. "I think that I needed to be sent down. I think that I needed this -- not just for these next couple of weeks, but for my career, just to find something that I'd been missing.
"I just know that I found my swing, and I'm going to be able to go out there and do my thing."
The Padres optioned outfielder Aaron Cunningham back to Tucson. He hit .167 in 12 at-bats for the Padres.
