The Bull is no baby, but he’s a lot lighter.

Rockies catcher Wilin Rosario, decked by influenza-B that put him in bed with a 103 fever and cost him 10 pounds, is back in the starting lineup for Sunday’s rubber game against the Padres.

Rosario was 228 pounds before his illness; he tips the scales at 219 now.

“I was 218 last week and I weighed myself today and I gained one (pound),” he said Sunday morning.

Asked if he wants to stay at his current weight or bulk back up, Rosario said: “I don’t know. I’m going to stay where I can hit bombs. If I hit the ball like this, I’m going to say here. If I need a little bit more weight, I’m going to go get it.”

Manager Walt Weiss welcomed The Bull back.

“He’s another weapon, another dangerous bat to our lineup,” Weiss said. “Bull does look a little smaller. But it’s good to have him back in the lineup. … No doubt about it, he’s another one of our guys who can hit it into the seats.”

But Rosario, hampered by a sore left hand, was hardly raking when he went on the disabled list. His average is just .239 and he’s hit only three homers with 15 RBIs and his on-base percentage is a middling .274.

Rosario’s last game was May 2. He made two rehab starts with Triple-A Colorado Springs, going 2-for-6 with a double.

So, how sick was he?

“I don’t know too much about the temperature, but I shook a lot,” he said. “I was cold. When I was here (in Denver), I couldn’t stay here because I was shaking a lot, because it was too cold. I had no appetite or nothing, because when I smelled the food, I wanted to throw up.”

CarGo’s knee

Carlos Gonzalez is coming off a nice game Saturday night — 2-for-3 with a two-run double — and is showing signs of breaking out of his lingering slump.

But he admitted Sunday that the tendinitis in his left knee, the knee he uses to drive for power, is still bothering him.

“I feel a little better; still fighting with that knee,” he said. “I think it’s showing in stolen bases. It’s kind of slowed down a lot. But I continue to get treatment every day and hopefully it gets better and I can bring that speed back to the club.”

Gonzalez enters Sunday’s game hitting .270 with seven home runs and 28 RBIs, but just two stolen bases.

“Right now, I’m just trying to concentrate on playing every day,” he said. “That’s what’s most important for this club, keep my legs in the game and my body there. Like we were saying in spring training, our goal is to play 150-plus games — me and Tulo. We understand if we do that, this team is going to be in a good position.”

CarGo feels discomfort in his knee the most when he’s on the bases, but it affects him at the plate, too.

“Sometimes, thinking about my hitting mechanics, and sometimes it bothers me (there) too. To have the leg kick and sit on that knee,” he said. “When I’m having that pain, even without trying, my reaction is to just get (off) of that knee and jump out front.
