Jansen reports no problems with heart in Coors return

DENVER -- Kenley Jansen pitched a scoreless inning Friday night and did not figure into the decision in the Dodgers' 7-5, 10-inning win, but it was still quite a milestone for the 25-year-old Dodgers reliever.

His most recent appearance at Coors Field was shaky in more ways than one. He allowed four runs in two-thirds of an inning on Aug. 27, then was rushed to the hospital with an irregular heartbeat that led to offseason heart surgery.

Jansen had ablation surgery to identify abnormal tissue in his heart and cauterized it to stop the abnormal electrical signals sent from this area to his heart.

"I've been thinking about coming back here for a week," Jansen said. "It's scary, but I know I'm fixed, so I just have to put it out of my mind."

Jansen was pleased to report he did not experience lightheadedness, rapid breathing or any of the symptoms he had last year.

"I didn't think about it during the game, but after the game, I wondered how I'd feel," he said. "I was totally fine. My heart rate was normal. You never know with the altitude. And doctors told me that some football players that have the surgery still have trouble at altitude and can't play anymore. So sometimes you worry a little bit, but I'm fine."

Mattingly tossed after arguing sixth-inning call

DENVER -- Dodgers manager Don Mattingly was ejected in the sixth inning of Saturday's game against the Rockies by first-base umpire Brian Knight for arguing a call on a comebacker to Zack Greinke.

With Nolan Arenado on first base and no outs, Greinke gloved Yorvit Torrealba's drive and threw to first to double-up Arenado.

Home-plate umpire Gerry Davis ruled that Greinke short-hopped the ball. Mattingly came out, and Davis called a meeting of the umpires. When they upheld the original call, Mattingly said something that drew an immediate ejection from Knight.

That sent Mattingly into a rage that lasted a few minutes as he followed Knight back to his position behind first base.

It was Mattingly's first ejection of the season.

After the game, Mattingly conceded the replay was "way too close for anybody to overturn it."

Crawford exits in third with left hamstring cramp

DENVER -- Dodgers left fielder Carl Crawford suffered a left hamstring cramp on a third-inning double and left Saturday's game against the Rockies.

Crawford followed a solo home run by Tim Federowicz and a single by Zack Greinke by punching a ball just inside third base. Greinke went to third, and Crawford felt the muscle twinge as he rounded first base.

"It's similar to the first time," said Crawford, who missed two games with a tight hamstring earlier this year. "It's just tight and sore, and I've been icing it.

Trainer Sue Falsone and manager Don Mattingly quickly made their way to second base and accompanied Crawford back to the dugout. He was replaced by Scott Van Slyke.

Crawford returned to the lineup Saturday after missing Friday night's game because he was still sore from running into the wall making a catch in Anaheim on Thursday night. He said he wasn't sure if the hamstring injury was related to the collision with the wall.

Manager Don Mattingly indicated the club needed to call up a healthy outfielder, and Yasiel Puig was held out of Double-A Chattanooga's lineup as a precaution in the event the club decides to bring him to Denver in time for Sunday's matinee.

Ryu questionable for series finale start in Colorado

DENVER -- Hyun-Jin Ryu said he "doesn't know" if he will make his scheduled start Sunday for the Dodgers because of lingering left foot pain, while Chris Capuano said he expects to make his scheduled start Monday night, despite a left triceps muscle cramp.

Ryu took a Mark Trumbo comebacker off the top of his left foot during his two-hit shutout Tuesday night. Although he completed the game, the foot still hurts. He threw a rare between-starts bullpen session Saturday, but it was only to test the foot with half-speed throws off the mound.

"That's where we are now," said a non-committal Don Mattingly, who joked he "may start [Skip] Schumaker tomorrow in center and pitch."

After Saturday's 7-6 loss in 10 innings, Ryu said the final decision would be made by management, but that "I never want to take the mound and put my team in jeopardy unless I'm fully comfortable I can be the pitcher I am. I wouldn't want to be out there unless I'm 100 percent."

If Ryu can't make the start, or the club wants to push him back a day, Matt Magill would probably be called up from Triple-A Albuquerque. Magill hasn't pitched for the Isotopes since May 25, so he would be fresh if the Dodgers need him.

"Considering how much it hurt that evening, it's healed faster than I thought," said Ryu, who continues to receive treatment for the bruise. X-rays taken of the foot were negative.

Capuano pitched well Wednesday night, but left after 5 2/3 innings because of the cramp. He pushed back his regular bullpen session from Friday to Saturday and came out of it optimistic.

"We're a go for Monday, for now," said Capuano. "I definitely still feel it a little bit, but I anticipate by Monday it will feel really good. I've had a lot of treatment. It's not the shoulder or elbow, but the belly of the triceps muscle. If you're sore as a pitcher, that's the best place."

Mattingly refuses to speculate Puig could be promoted

DENVER -- Matt Kemp is on the disabled list, A.J. Ellis missed his third consecutive game Saturday and Yasiel Puig is now playing center field at Double-A Chattanooga.

But don't ask Dodgers manager Don Mattingly to connect the dots and confirm that the club plans to bring Puig to the big leagues to take over in center field until Kemp returns.

Mattingly just shook his head back and forth when asked if he would talk about the plans.

Ellis said he was able to hit off a tee with no pain in his strained oblique, that it felt better than he thought and he was headed in the right direction. But Mattingly hedged when asked if that meant Ellis didn't need to be moved to the DL.

"We're pretty confident he won't need 15 days," said Mattingly, but "we still don't have to make a decision today, so we won't."

Disabling Ellis would open a spot for Puig or another center fielder. Skip Schumaker started in center for the second consecutive game Saturday.

Mattingly said his reports on Hanley Ramirez's first rehab game with Class A Rancho Cucamonga on Friday night were favorable. Ramirez is expected to continue rehabbing there at least through Sunday.

League remains closer after Friday's blown save

DENVER -- Dodgers manager Don Mattingly said he hasn't changed closers despite the game-tying two-run blast Brandon League allowed to Todd Helton in the bottom of the ninth Friday night.

"Not in my mind," said Mattingly, asked if he would make a change. "I don't want to be in between. We can talk about the game that gets blown, but the guy [Helton] is a pretty good player. It's not like he's walking guys and hitting a guy and there are bullets all over the yard.

"He made good pitches. He came in and attacked, and the guy had a good at-bat. Every time something happens you want to change, but I want to create some continuity and keep roles established."

Helton fouled off five two-strike pitches before unloading on the 11th pitch of the at-bat. Every pitch was a sinker, but Mattingly didn't second guess League for not throwing a splitter.

"He didn't try to go in, but that's what a good hitter does," Mattingly said. "You keep fighting as a hitter until the pitcher makes a mistake, and he did with the 11th pitch. I give my guy credit for throwing a bunch of good pitches that got fouled back in the stands instead of saying he didn't do his job."
