LOS ANGELES -- Rockies right-hander Tyler Chatwood's mechanics deserted him again at Dodger Stadium on Saturday night.
Chatwood tied a career high with eight walks in just 3 1/3 innings of a 4-0 loss to the Dodgers.
With strikes on just 41 of his 88 pitches, Chatwood gave up four runs. That is tantamount to giving the Dodgers the game when Clayton Kershaw is pitching. L.A. is 93-0 when scoring at least four runs for the lefty ace.
Chatwood entered the game 2-0 with a 1.73 ERA in June. He was 3-0 in his previous four road starts. But he was shaky from the beginning Saturday -- indicative of a season in which his control has shown up intermittently.
Four times he has walked just one, and another time he walked two. But Saturday was the sixth time he's walked four or more.

"I don't think it's something that's really alerting," Chatwood said. "It's just one of those days where you feel lost a little bit. Those are the times you've got to fight through it and give your team a chance to win. I was unable to do it tonight."
But what's going on around the rotation has at least the Rockies' fans, if not the club itself, sounding the alarm.
Chatwood's poor start came on the heels of unwinnable starts by rookies Jeff Hoffman, Antonio Senzatela and Kyle Freeland. Now the Rockies have their first four-game skid of the season.
Help is arriving, with lefty Tyler Anderson facing the Dodgers Sunday in his first start since May 30 because he had to nurse left knee inflammation. Jon Gray struck out six and gave up one run in five innings of a rehab start at Triple-A Albuquerque on Saturday, but he walked four. Righty Chad Bettis is kicking up his attempted return from testicular cancer.
Until all is settled, the Rockies need Chatwood -- their most experienced pitcher -- excelling.
"I felt like I beat myself tonight, and that's pretty frustrating to go home to," Chatwood said.
He issued a walk in the first and two in the second, 1-0. But the outing fell apart after he gave up Joc Pederson's third-inning leadoff home run on a first-pitch fastball. Chatwood walked the following hitter, and would walk five more -- including Kershaw on four pitches with the bases loaded.

Rockies manager Bud Black said he saw Chatwood's momentum going toward the left-handed batter's box more than toward the target, and the bounced fastballs were a sign of too long of a stride. He also saw Chatwood "quick off the rubber -- rushing, as we call it."
Chatwood, however, felt different.
"I didn't' feel like I was rushing today," Chatwood said. "Normally when you rush, you miss up. A lot of my misses were down. Maybe I focused too much on trying to get back in the zone, rather than just throwing the ball like I normally do."
Figuring it out and taking it to the mound is the next step.
