SAN FRANCISCO – Talking to the media before the game Sunday, Dodgers manager Dave Roberts bemoaned his team’s lack of a “winning” mindset recently.

Then they went out and did nothing to contradict him.

Giants left-hander Carlos Rodon allowed just two hits over the first six innings of a 2-0 shutout of the Dodgers Sunday afternoon.

Three sellout crowds filled Oracle Park this weekend, chanting “Beat LA!” and the Giants did just that.

The five-hit shutout completed the Giants’ first three-game sweep of the Dodgers since the last three games of the 2016 regular season. But it is only part of a stretch that has seen the Dodgers lose nine of their past 13 games – starting with a three-game sweep by the Pittsburgh Pirates at Dodger Stadium.

The Dodgers have been in first place in the NL West every day since April 14. But the San Diego Padres are now just a half-game back.

In the three games against the Giants, the Dodgers were held to four runs while going 2 for 24 with runners in scoring position and stranding 29 runners on base. It is the low point in a two-week downturn offensively that now includes two shutouts in their past six games and only 47 runs over their past 13 games (11 of those in their victory in Chicago on Thursday).

The Dodgers’ lineup is riddled with underperforming hitters. But the most glaring — and extended — slump belongs to Mookie Betts.

An MVP-level Betts made the Dodgers’ offense go in May. But he has not carried it into June, dragging the offense down with him. After another hitless game Sunday, Betts is 2 for his past 31.

The Dodgers did put the leadoff man on base in four of the first seven innings Sunday, three times on leadoff doubles – by Will Smith in the second inning, Chris Taylor in the fifth and Taylor again in the seventh.

Smith never advanced past second. Neither did Taylor in the seventh. In the fifth, he moved to third on a ground out and was stranded there.

Not only did the Dodgers go hitless with a runner in scoring position (0 for 10), they were 1 for 16 with any runner on any base. The lone hit with a runner on was Justin Turner’s single in the eighth that put the tying runs at the corners with two outs in the eighth. Taylor struck out to end that inning.

In the bottom of the inning, Taylor crashed into the wall in left field trying to make a play on Mike Yastrzemski’s double. Taylor wound up leaving the game after his sunglasses appeared to break and cause bleeding near his right eye.

Dodgers starter Julio Urias deserved better than the lack of support he got Sunday.

Urias got off to a rocky start, allowing home runs to two of the first three batters he faced. But he retired the next 16 in order and allowed just one more hit (a two-out double by Darin Ruf in the sixth) while going six innings.
