Kershaw then raced to the mound to share in the moment with Jansen (whom, you might recall, teamed up for a particularly dramatic finish to Game 5 of last season's NLDS win over the Nats).
After Ketel Marte's first-inning bunt single, Darvish sent down 13 in a row before Descalso hit his second homer of the series.
Darvish gave up one run and struck out seven in five-plus innings to send the Dodgers to the NLCS against the victor of the Chicago Cubs-Washington Nationals series.
"I don't think they're uptight, I just think we're a little frustrated because we haven't been playing Arizona Diamondbacks baseball", said Arizona manager Torey Luvullo before the game.

Bellinger, the likely NL Rookie of the Year, had 39 regular-season homers but was 1-for-12 in the NLDS before his opposite-field homer made it 2-0 in the fifth inning.More news: Amber Alert issued for abducted 3-year-old Texas girl

Meanwhile, his counterpart, Yu Darvish, was absolutely filthy through the first four innings for the Dodgers. Arguably the greatest pitcher of his generation, the three-time Cy Young Award victor has 144 regular season wins in his Dodgers career. He was also was tremendously efficient with his slider (27 pitches, 21 strikes, five swings and misses), and his cutter (21 pitches, 15 strikes, four swings and misses); the latter was a pitch the Dodgers encouraged him to emphasize. But the four-time all-star went more than a month without a win around the same time the entire team went almost three weeks with just one. And, it would put the Dodgers up 2-0.
In Saturday's game, Logan Forsythe helped lead the charge as he was 3-for-5 with a stolen base, three runs and an RBI. Clayton Kershaw - who didn't even need to pitch in relief in this particular NLDS after his memorable turn a year ago against the Nationals - can start the NLCS opener Saturday on seven days' rest, with Rich Hill, Darvish and Alex Wood all well-rested and ready to take their turn. Greinke faced 3-2 counts against five of his first eight batters and was at 54 pitches through two innings. Austin Barnes went 2-for-3 with a double, a walk, a stolen base two runs and two RBIs.
Ray escaped trouble in the third inning, despite continuing with his control issues.
The theme of the Diamondbacks this postseason was early exits for their starters.
Darvish, acquired from Texas in a trade deadline deal, struck out seven over five innings to outpitch Arizona's Zack Greinke and earn the righty his first postseason victory in three tries.
Greinke walked five in the first three innings, his season high. On Greinke's second pitch of the sixth, he served up an 89 miles per hour fastball that Barnes lined 398 feet to leftfield, restoring their two-run lead. Poor Fernando Rodney, the Diamondbacks closer, not only never got to fire a single arrow, he never even got to pitch in the series.
