Zack Greinke is on a roll as the Dodgers gear up for their first postseason appearance in four years.
Greinke, who will start Sunday against the Padres in the finale of a three-game series at Petco Park, has won his last seven decisions dating back to Aug. 5. The right-hander is 15-3 with a 2.75 ERA in 26 starts for the Dodgers this season and has not lost since July 25.
Greinke has had some eventful starts against the Padres this season. He broke his left collarbone in a benches-clearing fracas in San Diego on April 11, Greinke's second start with the Dodgers. He returned to Petco Park for the first time since his injury and fired eight innings of one-run ball on June 22, which began the Dodgers turnaround after a rough start to the year.
The Dodgers have already won the National League West, but they are still battling for home-field advantage in the postseason. Los Angeles trails the Braves by 2 1/2 games for the top spot in the league, and are two games behind the NL Central-leading Cardinals.
The Padres, meanwhile, are 10 games under .500 with eight games remaining in the season.
Andrew Cashner will take the mound for San Diego in what could be his final start of the season. Cashner has thrown 168 innings and started 25 games, both career highs. The Padres are watching his workload and could shut down the right-hander after Sunday.
Cashner is not showing signs of slowing down, though. He took a perfect game into the seventh inning against the Pirates on Monday, and finished with his first career shutout. Over 10 starts in the second half, he's 5-3 with a 2.36 ERA and a .198 opponents' batting average.
"The thing about Cashner was evident on Monday night, he still feels good and he's not showing any signs of any work-load struggles," said Padres manager Bud Black. "He really is one of our strongest guys. When we do strength and conditioning tests in Spring Training he grades out as one of our strongest and most powerful players.
"I think his delivery is efficient, and one thing that has always sort of surprised me over the last couple years is how he had some arm troubles. And that just might be a result of how hard he throws and the torque that he puts on his arm to get the velocity, but physically and mentally he's in a good spot. But we're still going to watch this next start and we'll see whether that's the end or not."
Dodgers: Young not looking ahead
• Michael Young said he hasn't thought about his plans after the season, despite rumors that the infielder is considering retirement.
"I'm too focused on what I'm doing on this team," said Young, who will be a free agent. "Winning is the sole priority, and we're playing as hard as we can in the name of winning games. Anything else is not on the radar. There will be a time and place for that, just not now."
Young, 36, was acquired Aug. 31 from the Phillies for Minor League pitcher Rob Rasmussen. He waived no-trade protection and accepted the Trade Deadline deal to the Dodgers for the chance to play in October. Young was acquired to be a role player on a deep Dodgers club that will require difficult decisions for the postseason roster.
Padres: Street in a groove
• Huston Street tossed a scoreless ninth inning Friday to record his 32nd save in 33 chances, and has converted 24 consecutive save opportunities, the second-longest streak of his career.
Since joining the Padres at the beginning of the 2012 season, Street is 55-for-57 in save opportunities and leads the Majors with a 96.5 percent save percentage.
• Jedd Gyorko smacked his 20th home run Friday, becoming only the fifth second baseman with at least 20 homers in his rookie season. Gyorko joined Joe Gordon (24 in 1938 with the Yankees), Dan Uggla (27 in 2006 with the Marlins), Alexei Ramirez (21 in 2008 with the White Sox) and Danny Espinosa (21 in 2011 with the Nationals).
• The Dodgers are one win shy of joining the Giants (403) as the only teams with at least 400 wins over the Padres.
