PHOENIX -- Kenley Jansen calls it a "slow start" to the season.
In two appearances, he has lost a game and blown a three-run lead. No one expects that from one of the game's most dominant closers.
Chris Owings hit a three-run homer off Jansen with two outs in the bottom of the ninth to force extra innings, and the Arizona Diamondbacks scored twice in the 15th to rally past the Los Angeles Dodgers 8-7 early Tuesday.
The first matchup between the teams since the NL-champion Dodgers swept their Division Series last October became the longest game in Chase Field history at 5 hours, 46 minutes.
"We're down to barely nothing," Arizona manager Torey Lovullo said, "and these guys found a way to win the game. It's a special night."
Or, more accurately, a special morning.
Chase Utley's RBI single shortly after midnight put the Dodgers up 7-6 in the 15th, but Nick Ahmed's run-scoring double tied it in the bottom of the inning and pinch-hitter Jeff Mathis, the last position player on the Arizona bench, singled home Ahmed with the winner.
Both teams used all their available relievers. Mathis was going to pitch if the game had remained tied.
Jansen blew one save in 42 opportunities in 2017, but this season has not started well. The Dodgers' closer gave up a home run to Joe Panik in a 1-0 loss to San Francisco in his first outing on Friday, then squandered a three-run lead in his second on Monday night.
"I definitely know I'm fighting with some stuff," he said, explaining that the timing of his delivery was a problem.
Both Jansen and manager Dave Roberts said the All-Star closer is healthy.
"I know that he's got pinpoint command, doesn't walk guys," Roberts said. "And I know there were some close calls tonight that didn't go his way. But regardless, Kenley still has the ability to throw strikes when he needs to. Just the pitch to Owings, it was a cutter that was down and in his nitro zone."
The pitch was recorded at 89 mph. Last season, Jansen averaged 93 mph on his cutter, which is the pitch he has mostly relied on.
"No, it's not mechanic," Jansen said. "He just got me. Who cares? Who cares? It's one game."
With the Dodgers up 6-3, Jansen got the first two batters to ground out but walked Paul Goldschmidt and A.J. Pollock, both on 3-2 counts, to bring up Owings, who hit the first pitch he saw into the left-field seats.
"That pitch was right where I was kind of looking," Owings said. "Definitely got us back in the game. From there, the rest is history."
According to ESPN Stats & Information, the Dodgers had entered Monday's game with a 364-0 record when entering the ninth inning with a three-run lead over the past eight seasons.
Owings became just the fourth player to hit a three-run homer or grand slam against Jansen, who was touched up a bit in the World Series last year, too. The right-hander gave up two homers, took a loss and blew one of his three save chances against the Houston Astros.
"Listen, those guys have bats," Jansen said. "They compete, too. Nobody wants to get beat. Nobody wants to blow saves. Nobody wants to lose games, but the situation of the game, it happens. What can I do? I've just got to bounce back tomorrow and help the Dodgers win."
Yasiel Puig made two fine defensive plays for the Dodgers in the 14th, catching Goldschmidt's drive at the right-field fence and then throwing out Ketel Marte trying to advance to second on a deep flyout by Pollock.
Yasmani Grandal reached base in his first five plate appearances for the Dodgers, including a two-run homer in the first inning, but bounced out to second with runners on first and third to end the 10th.
Marte became the seventh Diamondbacks player to triple twice in a regular-season game. He also did it in last year's wild-card victory over Colorado.
Diamondbacks: Lovullo said OF Steven Souza Jr. (strained right pectoral muscle) threw from 90 feet and swung the bat in the cage. ... 3B Jake Lamb was having his shoulder evaluated after some discomfort following a diving grab for a line drive, and a headfirst slide to score the tying run in the 15th.
LHP Clayton Kershaw, coming off a 1-0 loss to San Francisco in the season opener, takes the mound for the Dodgers and RHP Zack Godley makes his season debut for Arizona on Tuesday night in the second game of the three-game series.
