Turner activated, Triunfel optioned

ST. LOUIS -- Justin Turner returned to the Dodgers' active roster Friday, joining the club in St. Louis after missing the first half of July with a strained left hamstring.

Turner last played in the Majors on June 28 and had been on the disabled list since with the hamstring strain. The Dodgers activated him as the second half began Friday against the Cardinals, optioning infielder Carlos Triunfel to Triple-A Albuquerque.

"It's nice for us to get [Justin] back," Dodgers manager Don Mattingly said. "He's been a guy for us that has been really good off the bench and really good when he plays. It's just another weapon for us."

Turner is hitting .302 with three homers, 10 doubles and 21 RBIs in 59 games for Los Angeles. The 29-year old appeared in two rehab games at Class A Rancho Cucamonga on Sunday and Monday and went a combined 1-for-5 with two walks.

Triunfel, who has appeared in 11 games and hit .143 in four stints with the Dodgers this season, was with the club in St. Louis before being sent to Triple-A.

Rodriguez called up to combat Cards' lefty hitters

ST. LOUIS -- The Dodgers added to their bullpen depth Friday, recalling Paco Rodriguez from Triple-A Albuquerque, giving the club a left-handed reliever for its three-game series with the Cardinals.

The Cards started four left-handed hitters in the series opener Friday at Busch Stadium, and three more were available off the bench.

"For this series here, you want to have an extra lefty if you can," Dodgers manager Don Mattingly said. "They've got so many guys that you really want to be left-handed with, so it's nice to be able to have him."

Rodriguez made the Opening Day roster and has notched a 6.43 ERA in two stints with Los Angeles. He had a 4.56 ERA in 29 appearances for Albuquerque this season before being recalled Friday.

After his most recent stint, the Dodgers worked the left-hander on mechanics.

"It seemed like about a month ago it was, 'Hey, Paco has really been throwing the ball well,'" Mattingly said. "We knew at that point if we had an opportunity for him, he'd be ready."

That opportunity came Friday with an open roster spot after the Dodgers optioned Pedro Baez to Triple-A on Sunday before the All-Star break.

The 23-year-old Rodriguez owns a 3-5 record and a 2.65 ERA in 97 games in the Majors. The second-round selection in the 2012 First-Year Player Draft made 76 appearances for the Dodgers last season, going 3-4 with a 2.32 ERA.

Rodriguez moved quickly through the organization and has made just 50 career appearances in the Minor Leagues. He has a 3-3 career record and a 2.98 ERA in the Minors.

By deadline, Dodgers sign 30 of 40 Draft picks

ST. LOUIS -- The signing deadline for players selected in this year's First-Year Player Draft came and went Friday, with the Dodgers having signed 30 of their 40 selections.

Those signings included each of the team's top-14 selections and 20 of the first 22 picks.

The Dodgers' first-round selection, right-hander Grant Holmes of Conway High School (S.C.), has made three appearances (two starts) for the organization's Rookie club in Arizona, posting a 3.60 ERA in 10 innings.

The Dodgers spent over half of their allotted pool on Holmes by giving him a $2.5 million bonus, above his slot of $1.9805 million.

Worth noting

• Mattingly is hopeful that right-hander Josh Beckett, who last started July 6 and has been out with a left hip impingement, will return Tuesday to face the Pirates in Pittsburgh.

• Shortstop Hanley Ramirez, who last played July 10 and missed the final three games leading into the All-Star break with a right shoulder injury, returned to the lineup Friday.

"I'm confident that he's healthy today," Mattingly said. "That's really where we're at with that."
