Schumaker's suspension upheld by MLB

PHOENIX -- Dodgers outfielder Skip Schumaker's two-game suspension was upheld by Major League Baseball on Wednesday and he was just as annoyed as he was when he first received the discipline.

"I didn't do anything wrong," said Schumaker, who was suspended for what MLB called "aggressive actions" during the June 11 brawl with Arizona. "For pulling guys off each other I get suspended for two games. I appealed, but it didn't do any good. The video showed I didn't throw punches. Guys did more than me and nothing happened to them. It doesn't make sense.

Schumaker began serving the suspension Wednesday night, leaving the Dodgers a player short for the next two games.

Schumaker might have stood out in the video for two reasons -- as the on-deck hitter when Zack Greinke was hit by an Ian Kennedy pitch, Schumaker was already on the field and was one of the first Dodgers on the scene; he also didn't have a hat or helmet on and his shaved head was easily discernible in a scrum where all other participants were wearing caps.

"It's always an issue when you've got to play short a couple of days," said Dodgers manager Don Mattingly. "I know he appealed, but that's the way it goes."

Marmol allows HR in first Minors appearance

PHOENIX -- Reliever Carlos Marmol served up a home run to the first batter he faced Wednesday, the only run he allowed in one inning while pitching for the Dodgers' Class A affiliate, Rancho Cucamonga.

Marmol was acquired from the Cubs on July 2 along with financial considerations that included $209,700 in international signing space. In return, the Cubs received reliever Matt Guerrier, who, like Marmol, had been designated for assignment.

With general manager Ned Colletti in attendance, Marmol also allowed a single, struck out one and made a wild pickoff throw to first base while facing High Desert.

The Dodgers are hopeful they can resurrect Marmol, who they believe needs, in addition to the mechanical tweaks, a change of scenery after losing the Cubs' closer role and becoming a target of Wrigley Field critics.

Marmol accepted the assignment and reported to the club's Camelback Ranch complex in Glendale, Ariz., to work with instructors.

WWII vet Patterson is Dodgers' All-Star hero

PHOENIX -- David Patterson of Rio Rancho, N.M., will represent the Dodgers as one of 30 winners of the "Tribute for Heroes" campaign, a national initiative of MLB and People Magazine that recognizes veterans and military service members.

Patterson was awarded the Silver Congressional Medal of Honor and is a Native American who took part in every Marine assault in World War II as one of the Navajo Code Talkers.

Each winner will be included in All-Star Week festivities and will attend and be honored during pregame ceremonies leading up to the July 16 All-Star Game at Citi Field in New York.

Fans nationwide cast their votes at TributeForHeroes.com to select 30 winners from a pool of 90 finalists.

The "Tribute For Heroes" campaign supports Welcome Back Veterans (welcomebackveterans.org, powered by MLB.com), an initiative of Major League Baseball and the Robert R. McCormick Foundation, which addresses the needs of veterans after they return from service.

Major League Baseball has committed more than $23 million for grants to hospitals and clinics that provide post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) treatment to veterans and their families in a public/private partnership with "Centers of Excellence" at university hospitals throughout the country.

Beckett has rib removed in surgery

PHOENIX -- Dodgers pitcher Josh Beckett underwent surgery Wednesday in Dallas to remove a rib that was pressing a nerve and causing numbness in his pitching hand.

Dr. Greg Pearl removed the right first rib, which was causing thoracic outlet syndrome. The club expects Beckett to be ready for Spring Training next year.

Rehabbing pitcher Ted Lilly pitched a simulated game at Camelback Ranch as he attempts a conversion to the bullpen. He has another simulated game scheduled in Los Angeles this weekend.

Worth noting

• With its Tuesday broadcast of Los Angeles' 6-1 victory over Arizona, KCAL 9 attracted the largest audience for a regular-season Dodgers game on any local broadcast or cable outlet since Aug. 1 2007, when KCAL 9 attracted 505,000 viewers for a game between the Dodgers and Giants. Barry Bonds entered that contest with 754 career home runs, which at the time was one short of Hank Aaron's Major League record.
