Rojas impressing Mattingly with defense

MILWAUKEE -- Yasiel Puig's running catch of Josh Hamilton's drive to the fence on Thursday night in Anaheim was repeated constantly on TV highlight reels, but manager Don Mattingly had this question for reporters.

"What about Rojas?" Mattingly asked. "Nobody asked me about Rojas. He saved four or five hits."

Mattingly was promoting the reliable and sometimes spectacular play of Miguel Rojas, who was given a rare start at shortstop with regular Hanley Ramirez used as the designated hitter in an American League park.

Rojas had 10 assists without an error, started one double play and, in Mattingly's estimation, saved at least two runs in the 7-0 win.

Rojas is generally used as a late-inning replacement for Ramirez when the Dodgers are leading. That role, and the acquisition of Darwin Barney, made veteran Chone Figgins expendable, and Figgins has been designated for assignment.

Rojas was pressed into service early in the series opener in Milwaukee when Ramirez exited with an injury.

Beckett back on the DL with hip impingement

MILWAUKEE -- Josh Beckett was placed on the 15-day disabled list on Friday because of a left hip impingement that has resulted in a torn labrum and two cysts.

Beckett went on the DL on July 7 for a stretch of rest, but since his return, the discomfort has prevented him from making quality pitches.

The only cure for a torn labrum is season-ending surgery and a three-month rehab.

Speculation is that Beckett is likely done for the season and that he might be calling it a career. Although he is 34, it's a high-mileage 34, with 2,051 innings pitched. This is his third stint on the DL this season and 18th in a 14-year career.

Until the hip problem, Beckett was a Comeback of the Year candidate after missing most of last season with thoracic outlet syndrome, which required surgery to remove a rib. He threw a no-hitter on May 25, and through June his ERA was 2.02.

Manager Don Mattingly put the most optimistic spin on Beckett's injury, comparing it with a minor hip impingement that cost Clayton Kershaw one start in 2012.

"It sounds like Clayton's," Mattingly said. "He missed eight or 10 days, then he was good. I'm hoping that's the case. It's the same area. It makes a little bit of sense."

Mattingly hopes Beckett can resume throwing after 10 to 14 days off and called Beckett returning to pitch this season "possible."

The club reported that a new MRI also revealed a strained left groin. Hip impingements often send sharp pain into the groin area. When Beckett had an initial MRI before the All-Star break, he also received a cortisone injection. There was no word of another injection this time.

Beckett's latest setback triggered the acquisition of Roberto Hernandez, who took Beckett's Friday night start against the Brewers.

Hanley to undergo MRI after early exit

MILWAUKEE -- Shortstop Hanley Ramirez was removed from Friday night's game against the Brewers with a tight right side after playing one half-inning and will have an MRI on Saturday.

If the Dodgers need a replacement for Ramirez, they can choose from Erisbel Arruebarrena, Darwin Barney and Carlos Triunfel at Triple-A Albuquerque.

Ramirez felt the injury swinging in the cage prior to the game and reported it to trainers. Just before game time, he played catch with Stan Conte, vice president of medical services, watching nearby, and it was decided that he would start.

"One swing, and it tied up on me," said Ramirez. "I tried to play. [Manager Don Mattingly] wanted to be careful and took me out of the game to get treatment. What he did, I think, was smart. He doesn't want me to get worse."

Ramirez, a free agent after this season, hasn't been on the disabled list in 2014, but he's missed 24 starts with injuries to his calf and shoulders.

"The team is doing good, and obviously, I want to be in there every day," he said. "And this comes up and, like, what happened? I've worked hard to stay in the lineup, then overnight, something happens, and you get disappointed."

The Dodgers had the difficult schedule of a game in Anaheim on Thursday night, when Ramirez served as designated hitter, then an overnight flight to Milwaukee that landed at 6:30 a.m. and the Friday night contest in Milwaukee.

Ramirez was removed after walking with two outs in the first inning, replaced by Miguel Rojas. Rojas was then replaced as part of a seventh-inning double switch by Justin Turner, who misplayed three balls in Milwaukee's four-run seventh inning.
