MILWAUKEE -- Pitching at Miller Park is not the same as pitching at a high school diamond in Corvallis, Ore., which is where Kevin Gregg had been working out after being released by the Dodgers at the end of Spring Training.

Friday was Gregg's first game action since March 30 and his first big league game since last September. He gave up an infield single and then walked Ryan Braun before he was pulled.

"The first guy, I made my pitches, got the ground ball, and we weren't able to get an out on it, and I'm not going to let Braun pile on," Gregg said of his outing. "It was a matter of making [Braun] chase my pitches and deal with Rickie [Weeks] hitting behind him, who hasn't been swinging very well lately."

Gregg is in shape, just not game shape.

"Side sessions are not the same as the game," he said. "It's just getting my feet out there, getting into game situations. I feel good, I felt good yesterday, and it's just a matter of getting in that groove and getting the first-game jitters out of the way. It was exciting to get back out there."

After posting a 4.95 ERA in 40 games with the Orioles last season, Gregg started tweaking his mechanics this offseason. When he arrived in the Dodgers' spring camp, they suggested some changes, which were along the lines of what the right-hander was already doing.

"I started that in the offseason as I was looking for a job, and when I went in and got there, they said, 'Hey, we have some things we want to work on,' and a lot of it was similar to what I had done in the offseason," Gregg said.

The changes were simple, he said, such as being in a better position on the mound and adjusting his hands.

"It was little things that are easy to overlook, but very important," he said.

Castro extends league-leading hitting streak to 12

CHC@MIL: Castro's single extends hitting streak to 12

MILWAUKEE -- Cubs shortstop Starlin Castro singled to right with one out in the fourth inning against the Brewers on Saturday to extend his hitting streak to 12 games, the longest active streak in the National League.

Castro now has eight hitting streaks of 10 or more games since the start of the 2011 season, tied with the Yankees' Robinson Cano for the most during that stretch.

Since he made his big league debut on May 7, 2010, Castro has totaled 550 hits, the most in the NL in that span. Milwaukee's Ryan Braun was second, entering Saturday's game with 537 hits.

Borbon excited to join Cubs outfield

Must C Caught: Lucroy throws out Borbon to end it

MILWAUKEE -- After a whirlwind day on Friday, all Julio Borbon had to do on Saturday was get fitted for his new Cubs uniform.

On Friday, Borbon found out he was claimed by the Cubs at noon CT, then stuffed all of his belongings in four suitcases, caught an afternoon flight to Chicago, rode a limo to Milwaukee and arrived at Miller Park in the eighth inning when he ran into manager Dale Sveum in the clubhouse. Sveum had been ejected earlier.

"I was in there, and said, 'Hey, get your stuff on, there's a good chance you're pinch-running in this game,'" Sveum said.

Borbon, 27, did enter as a pinch-runner with two outs in the ninth against the Brewers and got the green light, but was thrown out trying to steal second to end the game.

"He got the green light, but unfortunately he did a slow slide," Sveum said. "He had the bag stolen easy and he slid too early."

What kind of player is Borbon?

"People say numbers don't lie, and it comes down to, I'm a guy who relies on speed," Borbon said. "I like to go out there and put some pressure on the defense. From the second I get up there, I like to bunt. It's no secret in the American League. I like to get out there, put some pressure on the pitchers."

Born in Starkville, Miss., Borbon moved to the Dominican Republic when he was 3 or 4, and lives in Santo Domingo in the offseason. He attended the University of Tennessee and played with Darwin Barney on Team USA in 2006. Funny, he didn't sound like he was from Mississippi.

"There are some words where I definitely have a little Southern accent," he said.

Sveum said Borbon could get a start if Alfonso Soriano wants a breather, but the veteran hasn't asked for a day off yet. Borbon said he was excited to join the Cubs and get a front row seat to watch what Theo Epstein does since taking over as president of baseball operations.

"My fiance, she's from Boston, and she knew him, and she was the first one to tell me he had done great things for the city of Boston," Borbon said. "From his background and his resume, he's on his way to doing the same thing here. It's exciting to become a part of that and know that you're going to go on to great things. That's what I see looking around here."

Extra bases

• The televisions in the visiting clubhouse at Miller Park were all tuned to the Red Sox game on Saturday as the Cubs watched the first game back at Fenway Park since the Boston Marathon bombing.

"It was a pretty emotional day and easy to tear up [watching that today]," Cubs manager Dale Sveum said.

He also heard Boston's David Ortiz's rather emotional statement regarding the city that may have needed a seven-second delay.

"It's a fitting, I guess, statement for the day," Sveum said.

• The Cubs and Brewers were still trying to figure out what happened in the eighth inning Friday night after a bizarre play. Milwaukee's Jean Segura singled to lead off against Kevin Gregg and stole second. Ryan Braun walked, and Shawn Camp entered. During Rickie Weeks' at-bat, Segura broke for third, there was a brief rundown, and he slid back into second. But Braun had advanced to second as well.

Second base umpire Phil Cuzzi called Braun out. Segura thought he was out, and headed for the Milwaukee dugout, but first-base coach Garth Iorg told him to stay at first. Darwin Barney tried to chase after Segura with the ball. Too late. Segura was safe, until he was caught stealing second to end the inning.

"It was obviously a strange play and the final result was a guy getting thrown out stealing the same bag," Sveum said Saturday. "That goes unnoticed a little bit that a guy got a caught stealing and a stolen base in the same inning of the same bag."

• Sveum didn't seen Braun mimic Green Bay quarterback Aaron Rodgers' touchdown dance after hitting a home run Friday. Rodgers just happened to be at Miller Park for the game.

"It's kind of part of the game," Sveum said of the antics. "I didn't even notice."

Did Sveum ever do anything like that?

"Not even close," he said. "I put my hands up one time on a walk-off homer and that was about it."
