LOS ANGELES -- Mitch Haniger’s career day at the plate wasn’t enough for the Mariners to snap their losing streak as Seattle fell, 6-4, to the Dodgers on Tuesday night at Dodger Stadium.

Dodgers starter Walker Buehler sat down eight Seattle hitters via the strikeout and induced seven ground balls through seven innings, but he couldn’t solve the riddle in the right-handed batter’s box that was Haniger, who took Buehler deep in the first and sixth innings to tie the American League leaders with 10 on the season.

As the second at-bat of the game, the sold-out crowd at Dodger Stadium was still getting settled when Haniger picked up his first long ball of the day. He blasted the third pitch of the at-bat, and the fourth of the game, 402 feet to right-center field.

"Mitch is having a great start to the season. Phenomenal game tonight against a really high-quality pitcher,” manager Scott Servais said. "He looks great. Working his tail off and looks like he always had, so really excited about the start he's had to our season.”

Haniger said he’s been working with the coaching staff to get right at the plate. The 96.1 mph fastball from Buehler was Haniger’s second opposite-field home run of the season, which is a pretty good sign that things are coming together.

"Over the weekend [against the Rangers], I didn't feel too good, so I came in today and worked with [hitting coaches Jared DeHart and Tim Laker] to try to get back to where my swing’s feeling good,” Haniger said. “It's always a work in progress, and today I had a talk with them about just kind of synching up my upper body with my lower body a little bit better and staying through the middle of the field.”

Seattle still was holding on to the one-run lead that Haniger provided in the first when Kyle Seager extended the Mariners’ lead in the fourth with a two-run homer. The comfortable three-run lead was extended once more in the sixth when Haniger stepped into the box against Buehler for the final time of the night.

Before Tuesday’s loss, Haniger was hitless against the right-hander in three at-bats. Three years after he faced Buehler the first time and with a detailed scouting report, Haniger packed a punch in his third at-bat of the night.

Unlike his first home run, Haniger pulled an 84.6 mph slider over the middle of the plate and sent it to the left-field bleachers to give Seattle a four-run lead.

"We've talked before about whether you want to hunt that fastball up or you want to try to push him down because he's effective at the top of the zone, that's why he throws up there,” Haniger said. “He's got really good stuff, so we're just trying to kind of set our sights, set a bar and try to get him below that and be aggressive, and we knew he was going to come after us.”

While Haniger’s progress at the plate was a silver lining in the loss, it also backed up left-handed starter Yusei Kikuchi’s career night. Kikuchi recorded his 200th career strikeout and established a new single-game high with 11, though the Dodgers’ rally against the bullpen kept him from recording the win.

The seventh inning was when things took a turn. The Mariners held a 4-1 lead when Kikuchi was removed with one out after Gavin Lux poked a grounder through an empty third-base side that put runners on first and second. Anthony Misiewicz took over and walked AJ Pollock to load the bases, struck out Mookie Betts in a nine-pitch at-bat and then gave up a two-run single.

“Eleven punchouts tonight, and he did it with all different pitches,” Servais said of Kikuchi. “A heck of an outing by him. Unfortunately, we weren't able to lock it down.”

Right-handed reliever Rafael Montero took over for Misiewicz and struck out Justin Turner to end the seventh, but he gave up a three-run homer to Lux in the eighth that gave Los Angeles a 6-4 lead.

The Mariners have lost three games in a row and are holding third place in the AL West with an 18-18 record.
