Wieland's elbow feels fine after catch session

PHOENIX -- Pitcher Joe Wieland, who is recovering from right elbow surgery in March, was in the clubhouse on Wednesday afternoon mingling with his teammates.

More than that, though, Wieland was at Chase Field to test his elbow with a session of playing catch at 105 feet. He'll progress to 120 feet next week, then 135 feet and 150 feet.

And after that?

"Hopefully the middle of next month, I'll be able to start my [Minor League] rehab assignment," Wieland said.

Wieland was nearly to the point where he was back from Tommy John surgery on July 27, 2012, when he felt soreness in his right elbow during Spring Training. He had the elbow examined by a doctor which led to surgery that repaired an impingement and removed loose bodies in the elbow.

Wieland has been working out and rehabilitating his elbow at the team's Spring Training facility in Peoria since. Better still, he's optimistic about getting in games next month.

"One-hundred percent ... it feels like my old, TJ-free elbow," Wieland said.

For as eager as Wieland is to get in a game again, he's taking the patient approach to his rehabilitation -- which isn't always easy.

"It's patience," he said. "The way I've looked at it is when I'm ready, God will let me know when I'm ready. We'll go from there."

Grandal's hand good to go for finale vs. D-backs

PHOENIX -- Imagine the surprise Padres manager Bud Black received early Wednesday when he picked up his phone to see a text message from catcher Yasmani Grandal.

"I was at the hotel and got a text, Yazzy said, 'Buddy, I'm good ... I want to play tonight,'" Black said.

Black was under the impression that Grandal would likely need Wednesday's series finale off after D-backs first baseman Paul Goldschmidt hit Grandal's left (glove) hand with a swing in the seventh inning on Tuesday.

Grandal was called for catcher's interference but, worse yet, initially felt he sustained a broken finger or a fractured knuckle. It turns out he did neither, as X-rays came back negative.

So less than a day after the injury, Grandal was back in the starting lineup.

Black asked Grandal, who lives in the Phoenix area, if his swing and grip strength were good and then had to see for himself. Grandal arrived at Chase Field early and took a handful of swings in the batting cage several hours before the game started.

Grandal got treatment on the hand after Tuesday's game, which continued after he went home with ice and compression work. When Grandal woke up Wednesday, he felt considerably better.

"He's fine and he's good to go," Black said. "He's a fast-healer."

Grandal has proved to be a fast-healer before in terms of coming back from August knee surgery to make the team's Opening Day roster even though many figured he wouldn't be ready.

A's send Friars pitcher to complete Blanks trade

PHOENIX -- The Padres didn't wait long to complete their May 15 deal with the A's that saw them send first baseman/outfielder Kyle Blanks to Oakland for Minor League outfielder Jake Goebbert.

The team announced on Wednesday that it received 19-year-old right-handed pitcher Ronald Herrera from the A's as the player to be named in the deal.

Herrera, 19, was 3-4 with a 3.38 ERA in nine starts for Oakland's Class A affiliate in the Midwest League, striking out 35 batters in 50 2/3 innings while issuing just 10 walks.

The Venezuelan was originally signed by the A's in December 2011 for $20,000 and posted a 3.36 ERA in three seasons in their system.

Herrera will report to the Padres' low-A affiliate, the Fort Wayne TinCaps, of the Midwest League and will likely start there on Friday.

In parts of three seasons with the A's, Herrera was 12-12 with a 3.36 ERA in 187 1/3 innings. He had 145 strikeouts and just 43 walks over that stretch.

"We targeted him as a guy we saw in the Arizona rookie league and in the Midwest League," said Padres assistant general manager A.J. Hinch. "He's a good athlete with a good arm and has a good feel for what he's doing. We like the arm and his ability to command the fastball."

Short hops

• Outfielder Will Venable, who didn't play in the first two games of the D-backs series because of his sore right foot, was available on Wednesday, Black said. Venable was hit by a pitch on Sunday and had some swelling in the foot. He was out Monday and was available to play on Tuesday.

• Black said that it's an almost certainty that Carlos Quentin will serve as the designated hitter during the team's Interleague series in Chicago against the White Sox, which begins on Friday.
