SAN FRANCISCO >> Months from now when the season has played out to its conclusion, the Dodgers might have regrets about not doing more at the trade deadline.

For now, though, they seem to have everything they need right here.

After building an early six-run lead, the Dodgers nearly saw it disintegrate in the chill Bay air before Evan Phillips rode to the rescue, holding the line with the bases loaded. Peril averted, they landed the knockout blow later, taking a 9-5 victory over the San Francisco Giants Tuesday night.

The win was the Dodgers’ 25th in their past 30 games and maintained their 12-game division lead over the hyperactive-at-the-deadline San Diego Padres.

A big early lead had all but melted away when Tyler Anderson walked Luis Gonzalez and David Villar to start the sixth inning. Joey Bart bunted for a single against Phillips to load the bases with no outs.

But Phillips got a favorable strike three call on LaMonte Wade Jr. then got Dixon Machado to bloop one harmlessly to second baseman Gavin Lux. A four-pitch dismissal of Austin Slater defused the threat.

It was the kind of situation that would normally have belonged to Blake Treinen … or Daniel Hudson … or Brusdar Graterol. With each of those three subtracted from the Dodgers bullpen over the course of the season, Phillips has emerged as the type of “fireman” reliever so critical to the Dodgers’ bullpen strategy.

In 24 appearances since late May, Phillips has been charged with just one earned run while giving up 10 hits and striking out 27 in 23 increasingly high-leverage innings.

It shouldn’t have come down to Phillips’ heroics Tuesday. The Dodgers had the Giants on the ropes early but let them slip away.

They scored four times in the second inning against former teammate Alex Wood, getting three hits, a hit batter and benefiting from the Giants’ shoddy defense. They scratched together another run in the third and made it 6-0 on Mookie Betts’ leadoff home run in the fourth.

But nearly all of that lead disappeared in the bottom of the fourth when Anderson gave up six hits including and RBI double by David Villar and a two-run homer by Joey Bart.

The nightly “Beat L-A!” chants gained vigor until the Dodgers silenced them in the eighth by stringing together four consecutive two-out, extra-base hits.
