Haren to have next start pushed back

SAN DIEGO -- The Dodgers plan to use rookie Carlos Frias as a sixth starter for Wednesday's game against Washington and push back Dan Haren to Friday night against Arizona.

Manager Don Mattingly confirmed Haren would pitch Friday. He wouldn't confirm the decision on Frias, who was optioned to Triple-A Albuquerque before Sunday's game to make room for starter Hyun-Jin Ryu's return from the disabled list and technically isn't on the 25-man roster.

Frias is eligible to return to the club Tuesday, after the Monday end of Albuquerque's season. After Sunday's option, Frias threw a bullpen session of starter's length, while Haren did not throw off the mound. Haren would normally throw a session three days before a start.

Haren is coming off a quality start Friday night, when he allowed two unearned runs in six innings. Because Wednesday's game against his former team starts at 12:10 p.m. PT, he would have less than the normal five full days between starts. Mattingly said that was one reason for the decision.

A sixth starter also will provide extra rest for everybody, including Ryu, who just came off the disabled list, and Zack Greinke, who has been dealing with elbow tenderness.

The decision also will line up Greinke, Ryu and Clayton Kershaw to pitch in San Francisco against the Giants on Sept. 12-14.

Haren is 3-1 with a 4.26 ERA against Arizona this year, and 0-1 with a 4.50 ERA against Washington.

Of course, conspiracy theorists should have fun with the notion that pushing Haren back could compromise his chances of throwing 180 innings this year, which would trigger a conditional option for a 2014 salary of $10 million.

Haren has thrown 156 innings, figures to have five starts remaining and would need to average five innings each to guarantee the contract. He is 11-10 with a 4.27 ERA and hasn't missed a start.

Haren reiterated after Sunday's game that he hasn't even decided if he will pitch next year, regardless of contract status.

"I didn't come into this season shooting for a number of innings, I was shooting to pitch good," he said. "If it happens, it happens. I'm undecided about next year regardless of what happens."

Frias last pitched one inning in relief of Haren on Friday night. He has a 5.65 ERA in eight appearances after replacing the injured Chris Perez in the bullpen, but made 20 starts this year splitting time between Albuquerque and Double-A Chattanooga.

Dodgers activate Ryu and Uribe from disabled list

SAN DIEGO -- The Dodgers couldn't wait for Monday's expansion of rosters, activating starting pitcher Hyun-Jin Ryu and third baseman Juan Uribe on Sunday and optioning reliever Carlos Frias and infielder Miguel Rojas to Triple-A Albuquerque.

Ryu allowed one run over seven innings in Sunday's 7-1 win against the Padres after missing 16 days with a strained glute muscle. Uribe had been out with a strained right hamstring, and he drove in two runs on Sunday.

Both optioned players are eligible to return Tuesday, after the conclusion of Albuquerque's season. Both remained with the Major League club and worked out Sunday.

Frias, in fact, might start Wednesday's game against Washington.

The Dodgers also will promote a handful of players Monday. The most likely are outfielder Joc Pederson, catcher Tim Federowicz, infielders Erisbel Arruebarrena and Alex Guerrero and reliever Yimi Garcia.

The club also was in on talks for left-handed slugger Adam Dunn before he was dealt by the White Sox to Oakland.

One possible September callup who has been off the radar is left-handed reliever Onelki Garcia, who has been out all year after elbow and knee operations. He was to make his season debut for Class A Advanced Rancho Cucamonga on Sunday, and Don Mattingly said Garcia is further along in his recovery from injury than Paco Rodriguez, who has a Teres Major muscle strain.
