Hard to believe, but there have been just 13 combined runs scored during the first three games of this series. Not surprising, all three games have gone Under. 
I see a turnaround coming in the finale of this series. The Padres are a strong offensive club on the road away from Petco Park. The Brewers rank eighth in the majors in homers.
The Over is 13-4-1 (76 percent) the past 18 times the Brewers have played Game 4 of a series. 
The pitching matchup is lefty Joey Lucchesi versus Jordan Lyles. 
Lucchesi is coming off his worst outing giving up a career-high eight runs on nine hits - six of which went for extra bases - in just 3 2/3 innings in a 10-8 road loss to the Rockies this past Friday. That was at Coors Field. Miller Park, the site of this matchup, is another hitter-friendly park. 
The Brewers can expect to start righthanded hitters Keston Hiura, Ryan Braun and Lorenzo Cain against a southpaw starter. Braun and Cain didn't start Wednesday's game because San Diego threw righthander Dinelson Lamet. 
Lyles pitched for San Diego last year. So the Padres know him. Lyles has a 5.02 ERA in 13 career appearances against San Diego, including nine starts. 
The Padres have a .434 slugging percentage on the road compared to .398 at home. They also are batting .249 away compared to .232 at Petco Park.
