Rivera has had a front-row seat for greatness

PHOENIX -- Rene Rivera, pitcher whisperer?

The 31-year-old catcher smiles and shrugs sheepishly at the mere suggestion that he might have helped play even a small part in helping mold two of the top pitchers in baseball -- Clayton Kershaw and Felix Hernandez.

"No," Rivera said. "But sometimes I just have a feeling that when I catch someone, I can tell if they're going to be good or not. With Kershaw I could tell. And with Felix it was the same."

Rivera first caught Hernandez when he was an 18-year-old in the Mariners system in 2004, with San Bernardino of the California League.

Four years later he had the chance to work with the then-20-year-old Kershaw in Double-A Jacksonville of the Southern League.

There was something so similar about Kershaw and Hernandez at that young age, something aside from raw talent and a supreme skill set that stood out.

"It was the way they approached the game, the way they competed," Rivera said. "The way they acted on the mound. [Kershaw] looked like a big leaguer in Double-A."

Rivera was reminded of this on Thursday, when Kershaw allowed one run in eight innings, striking out 10 in a 2-1 victory over the Padres. The one run he surrendered came on an RBI single to none other than his former batterymate Rivera in the seventh inning.

Although Rivera didn't have the chance to work with Tyson Ross in the Minor Leagues, he has similar strong feelings about Ross' upside. That much has shown in 2014 for Ross, an All-Star for the first time, who took a two-hit shutout into the eighth inning of Thursday's loss to the Dodgers.

"[Rivera has] helped me out tremendously the last two years," Ross said. "We sit next to each other on the bench and talk all the time. He's been huge for my career."

Luebke's recovery takes big step

PHOENIX -- Cory Luebke's road back from a second Tommy John surgery in February took a positive turn last week, when he played catch for the first time.

"I had to find my glove," Luebke joked on Friday at Chase Field.

Luebke made 30 throws from 45 feet and will do so three times a week for the foreseeable future as he continues his rehab.

"It felt good to throw again," he said.

Luebke has spent his entire time since his surgery in Arizona, working out and living in Gilbert with Allen Gruver at the Postural Restorative Institute, where he's also worked on strengthening his hips and core muscles.

Luebke's rehab protocol is similar to the one he had after his first Tommy John surgery, on May 23, 2012, although the throwing program has been altered, with more time built between throwing sessions.

The good news, he said, is that having done this before has provided a blueprint for what's ahead.

"I have a better idea now of where I'm at," he said.

Manager Bud Black had a chance to talk with Luebke on Friday and watched him play catch in the outfield before the game.

"He feels good about where he's at," Black said. "It's a long process, but he's indicated his elbow feels different [in a good way] at this stage.

"He's excited about the next six months. And maybe we're getting a bit ahead of ourselves, [but] he's excited about being a Padre in Spring Training."

Luebke would be right around 12 months to the day of his second surgery (Feb. 18, 2014) when pitchers and catchers report for the start of Spring Training 2015. The "typical" recovery from Tommy John surgery, if there is such a thing, is usually between 12 and 18 months.
