On Sunday, Perez gave up just five hits in seven strong innings of a 3-0 win over the Rockies—his fifth victory in six decisions.
For Colorado, Oliver gave up three unearned runs and four hits in eight innings in his fourth straight defeat following a three-game winning streak.
Perez’s win came after the worst outing of his career, an 18-4 loss to the Houston Astros on Aug. 26 in which he gave up a season-high 10 earned runs and 10 hits in 4 2-3 innings.
“Same guy,” he said. “I never change. I did nothing different than in Houston. I believe in my ability, why change? If I have four good starts for every one bad start, I’m going to the Hall of Fame.”
However, manager Jim Tracy said he noticed some differences in the two starts.
“Odalis threw the same pitches he did in his start in Houston,” Tracy said. “The difference is that tonight he had better location, a much better mix of pitches, and did a much better job of using both sides of the plate.”
Perez has allowed at least six earned runs in five starts this season, including nine in a 12-5 loss to the Rockies on May 29. However, the 26-year-old left-hander has also allowed one earned run or fewer in seven starts.
On Sunday, he became the first Dodgers left-hander since Fernando Valenzuela in 1986-87 to win 11 games in consecutive seasons.
The Dodgers beat the Rockies 8-7 on Friday, remaining tied for third with Chicago in the NL wild-card race, three games behind Philadelphia. The Cubs beat the Milwaukee Brewers and the Phillies beat the New York Mets on Friday.
