LOS ANGELES >> Game 4 of a potential National League Division Series between the Dodgers and Washington Nationals would be played on Oct. 11. But the auditions to start that game are beginning this week.Left-handers Brett Anderson and Scott Kazmir will return from their health issues to start Thursday and Friday, respectively, against the Colorado Rockies. In both cases, the Dodgers will be evaluating the veterans for inclusion on the postseason roster.Kazmir has not pitched in a game since Aug. 22 due to thoracic spine inflammation. He was scheduled to make a rehab start for Triple-A Oklahoma City over the weekend but the OKC Dodgers were eliminated from the playoffs and Kazmir threw a simulated game on Sunday instead.During that 60-pitch workout, Kazmir developed a blister on the middle knuckle of his ring finger. He threw a 35-pitch bullpen session at Dodger Stadium on Tuesday with the blister covered and was pronounced ready to pitch. “With Kaz, he’s been dealing with injuries for the second half of the season,” Dodgers manager Dave Roberts said of Kazmir, in particular. “Talking to Scott and (pitching coach Rick) Honey(cutt), he feels good and he’s in a good place.“I think we have to find out what we have in him. He’s a guy that we have high expectations for. We have all year. It’s been a tough year for him. But where he’s at we’re confident he can regain his form and pitch well for us.”The Dodgers have to “find out” the same thing about Anderson who has made just two big-league starts this season since returning from back surgery – and both were horrible. He allowed 11 runs on 14 hits (three home runs) in just four combined innings in those two starts. Shut down with a blister on the index finger of his pitching hand following his most recent big-league start on August 20, Anderson made one rehab start for Single-A Rancho Cucamonga early this month but aggravated the blister. He finally appears to be healthy after throwing five solid innings for Triple-A Oklahoma City in its playoff series last week.“When Brett is right – and he hasn’t been right his last couple turns with the blister, the ball wasn’t sinking,” Roberts said. “But from what I understand his last start he was right and the ball was sinking. We feel he gives us a very good chance to win tomorrow night and then after tomorrow night we’ll see where the next start takes us. And I think the same thing for Kaz as well. Kaz hasn’t been healthy but I’ve got complete confidence in our training staff and in Kaz that he feels ready to give us a chance to win. I think his track record has to be given some credit, some acknowledgement.” Newsroom GuidelinesNews TipsContact UsReport an Error Rookies Brock Stewart and Jose De Leon are also “in the mix,” Roberts said, though he indicated Ross Stripling would be considered more for a long relief role on a potential playoff roster.All of this could be academic anyway. The schedule for a best-of-five NLDS makes a three-man rotation an option if a team is willing to bring back its Game 1 starter on three days’ rest to pitch in a Game 4. The Game 2 starter would line up to pitch Game 5 on regular rest.Kershaw has done the Game 1-4 short-rest combo in the NLDS each of the past three Octobers. That decision will carry more weight this season given the fact that Kershaw spent 75 days on the DL this season with a herniated disc in his lower back.Elbow roomDodgers catcher Yasmani Grandal opened the season on the DL with a strained right forearm that impacted his slow start. Now a sore right elbow that Roberts acknowledged was “a similar thing” could impact Grandal’s play down the stretch and into the playoffs.Roberts gave Grandal back-to-back days off over the weekend in Arizona to rest the elbow and had him out of the starting lineup for the third time in five days Wednesday, giving Carlos Ruiz the start against Giants left-hander Matt Moore. The elbow discomfort is likely to be an issue for the remainder of the Dodgers’ season and into the playoffs.“I think it’s something that he feels considerably better than he did four or five days ago,” Roberts said Wednesday. “I think it’s still going to be there but I don’t think it’s going to impede any type of performance.”A year ago, Grandal’s offensive production tailed off dramatically in the final two months of the season as he played through a shoulder injury that required off-season surgery. He is in the middle of a similar dropoff. Over his past 24 games, Grandal has gone 13 for 73 (.178) with 27 strikeouts and a .620 OPS. In his 38 games before that, he had a .307 average, 1.122 OPS and 15 home runs.
