Johnson to have Dr. Andrews inspect forearm

SAN DIEGO -- Pitcher Josh Johnson, on the disabled list since March 21 with a right forearm strain, will be examined in the next week by noted orthopedic surgeon Dr. James Andrews.

Andrews did the cleanup surgery last October on Johnson's right elbow, removing bone spurs. It was 2008 when Andrews performed Tommy John surgery on Johnson, then a member of the Marlins.

"The general view [of Johnson's rehabilitation] has been good days and bad since we shut him down," said Padres general manager Josh Byrnes. "We'll get him in to see Dr. Andrews next week, get another set of eyes, and see where we are. I wish we all knew more."

The Padres signed Johnson to a one-year deal worth $8 million in November, with the hopes he could rebuild his credentials and be a force in the starting rotation.

The Padres hold a club option of $4 million for 2015 if Johnson is unable to make at least seven starts -- risk protection given his health issues last season.

Johnson was having a good -- and for him, an ordinary -- spring, posting a 3.38 ERA in his four starts when he woke up with a swollen forearm after an outing. He had an MRI shortly thereafter that confirmed the strain in the flexor pronator muscles of his right forearm.

Does Byrnes think Johnson will pitch for the Padres this season?

"I'm not sure," he said. "We'll know more next week."

Johnson received a cortisone shot on April 2 and said he felt better afterward. Still, there have been enough days of not knowing what would happen next to frustrate him beyond belief.

"It still drives me crazy," he said Tuesday. "It's a waiting game. We just want to do what we can to make sure it's 100 percent."

Cabrera racking up doubles in leadoff spot

SAN DIEGO -- Chances are that Padres leadoff hitter Everth Cabrera isn't going to finish among the top five in the National League in doubles this season, but after 13 games, he's tied for fourth with six doubles.

"It's great, he's using the whole field," said Padres manager Bud Black. "We're seeing a nice job out of that leadoff spot. Cabby's doing a good job of taking pitches, fouling balls off and letting the other guys see a high number of pitches."

Cabrera, who was a late scratch Tuesday with right knee soreness, has a .340 average and a team-high 18 hits. He's hitting .333 from the right side and .341 in 44 at-bats from the left side with four of his six doubles.

Last season, Cabrera had 15 doubles in 381 at-bats. So far, he has six in 53 at-bats.

"With Cabby, we're still working on shortening his stroke. He and [hitting coach Phil Plantier] are talking about his ability to turn on the ball, turn on the fastball and get it into right-center. You can't complain about the batting average right now," Black said.

Cabrera also leads the team with 17 strikeouts.

"We need to get him to cut down on that strikeout total," Black said. "He's expanded the zone a little bit, which has led to the strikeouts."

Bullpen arms fresh for long stretch before off-day

SAN DIEGO -- Manager Bud Black was joking Tuesday that he needs to "reintroduce myself" to rookie reliever Donn Roach, who has made just two appearances this season and none since April 4.

"I see this guy named Roach walking around the clubhouse but I never see him play," Black joked. "I've got to get him in there."

The Padres, who are currently carrying two long relievers -- Roach and Tim Stauffer -- haven't needed Roach lately, as the starting pitchers have generally done a better job of working deeper into the games in the second week of the season.

Roach might be seen before too long, as the Padres are in a stretch of 20 consecutive days without a day off. The team won't have a scheduled off-day until May 1.

"That's a function of the types of games we're playing. His innings in the first part of the season have not really been required. But he'll get in there. You can't just pitch with just 10, 11 guys."

The Padres have six more games at home, counting Tuesday, before embarking on a 10-game road trip to Milwaukee, Washington and San Francisco.

"This stretch we're in now, we're going to use all 12 guys," Black said.

Worth noting

• Shortstop Everth Cabrera was a late scratch Tuesday with a sore right knee, the team announced. Alexi Amarista got the start at shortstop. Cabrera leads the Padres with a .340 average and 18 hits. He's started each of the first 13 games this season.

• Right-hander Burch Smith, a member of the rotation for Triple-A El Paso, has landed on the seven-day disabled list with muscular soreness in his right forearm. The Padres expect him to be ready for his next start, but they needed to make a roster move to add another pitcher so they wouldn't be shorthanded in the interim. Smith is 0-2 with an 18.56 ERA in two starts. He's allowed 11 runs on 13 hits in 5 1/3 innings.

• Pitcher Casey Kelly, working his way back from Tommy John surgery last April, took a step forward in his rehabilitation program on Tuesday, when he threw two innings in an extended Spring Training game in Arizona. He told the organization that he felt good afterward, said general manager Josh Byrnes.
