In a muddled National League Cy Young award race, Jacob deGrom could be considered the front runner.

“There’s some strong points we can all make that deGrom is leading this race,” manager Mickey Callaway said before the Mets’ 3-0 victory over the Dodgers on Saturday.

DeGrom’s stock rose even further with a three-hit shutout over seven innings against one of the NL’s premier lineups. The right-hander saw his ERA drop from 2.70 to 2.61.

A month ago, Hyun-Jin Ryu wore the front-runner label for the award, but a rough stretch opened the door for competition that also includes Nationals ace Max Scherzer and Braves rookie Mike Soroka. But on Saturday, the lefty Ryu rebounded with seven scoreless innings against the Mets, dropping his ERA from 2.45 to 2.35. In the middle of last month, Ryu owned a 1.45 ERA.

Entering play, deGrom’s 6.3 WAR ranked first among NL pitchers, according to baseball-reference.com, along with his 231 strikeouts. DeGrom’s .610 opponents’ OPS ranked second, and he was third in WHIP at 1.03. He was fourth with a 2.70 ERA, and his 183 innings pitched ranked fifth.

Ryu was not among the NL’s top 10 in K’s or innings pitched — two barometers generally used by voters.

“I am going to be biased toward deGrom, because I get to see him every single day,” Callaway said of last year’s winner. “I don’t get to see Hyun-Jin all the time. But if you just look at the numbers, the strikeouts, all the peripheral numbers, deGrom excels in all those areas, so there is that and I can see how hard this guy works, what he has to go through every day to go out there and be an ace of a staff and I get to watch him pitch and it’s hard for me to fathom that anybody is better than him out there.”

Seth Lugo struck out the side in the eighth, extending his scoreless inning streak to 14 since Aug. 17.

The Mets selected the contract of left-handed reliever Donnie Hart from Triple-A Syracuse. Hart appeared in one game for the Mets, on Aug. 4 against the Pirates, and pitched a perfect inning. To clear space on the 40-man roster, reliever Eric Hanhold was designated for assignment.

Callaway was asked about the possibility of Jed Lowrie starting a game. The veteran infielder has been used strictly as a pinch-hitter in the week since he was activated from the injured list.

“Right now, we know he’s an option, and he’s going to continue to be,” Callaway said. “We’re trying to get in the playoffs and we are going to continue to play the players we think are going to allow us to do that.”

The Dodgers had a nine-game Citi Field winning streak, dating to 2016, snapped. The Nationals hold the longest Citi winning streak among opposing teams — 12 straight games in 2013-14.
