The game was tied 3-3 with one out in the seventh, when Sexson crushed a 2-1 pitch from Dodgers reliever
(2-2) over the center field wall to put the Brewers in front.
With the victory, Milwaukee has won three of its last four road series.
"To get two and get out of here is a great thing for our team," Sexson said. "Mota is tough, he is one of the tougher guys coming out of the pen. I just tried to stay back on the fastball. I got some good back spin off the bat and it carried out."
Sexson drove in a pair of runs for the Brewers. The first baseman's sacrifice fly in the top of the fifth inning plated
and sparked a two-run rally that put Milwaukee on top, 3-2.
's RBI single in the bottom half of the fifth tied the game.
"We are definitely not one of the most talented teams out there," Sexson said. "So we have to play a perfect game to win every night. I think it goes to show how hard everyone in here is working to be able to take two from a very good team like the Dodgers."
Sexson is batting .287 (31-for-108) with eight homers and 20 RBI on the road this season.
(1-0) struck out two in 1 1/3 innings and notched the win. Four Milwaukee relievers combined on 3 2/3 hitless innings.
"It was a big game for us, it was a game we really wanted to win," Brewers manager
said. "Playing a quality team like the Dodgers, they swept us last week and, after the loss last night, it was our goal to win two out of three. We got some big two-out hits and it was a big all around win."
The Brewers have driven in 17-of-21 runs on their road trip with two outs.
With two outs in the second,
deposited the first pitch from Dodgers starter
into the left field stands to break the scoreless deadlock.
"I didn't throw very good pitches today," Ishii said. "I should have gotten ahead of hitters and take advantage of that. When they are fouling off a lot of pitches, my pitch count is going to be high. I wanted to get in a good rhythm early, so I started from the stretch. Unfortunately, I was not able to find a good rhythm."
Ishii allowed three runs and six hits in five innings, throwing 122 pitches before being replaced by Mota.
"We came in here and we knew we had to make adjustments or we would get swept again," Yost said. "It goes to show the quality of our players we have in here to win two out of three, it was a big boost for us."
's two-run shot in the fourth - his first homer in 43 games - put Los Angeles ahead, 2-1.
"It is frustrating, we are just not getting it done," Jordan said. "We had a good run for a while, you just hope you can sustain it. Baseball is a game of winning streaks and losing streaks. You just have to keep working hard and fight through it."
After Sexson homered,
's RBI single with two outs in the top of the fifth opened a 3-2 cushion for Milwaukee.
"We came in here and we knew we had to make adjustments or we would get swept again," Yost said. "It goes to show the quality of our players we have in here, to win two out of three. It was a big boost for us."
