There were plenty of reasons why plunking each other with baseballs seemed insignificant by the start of the Dodgers and San Diego Padres' meeting Monday, the first since a benches-clearing brawl between the teams last week.

Hours before, the players were reacting to bombings at the Boston Marathon and minutes prior to the game all were on hand to watch a celebration of Jackie Robinson, who was hit by his fair share of pitches in situations far more significant.

There was plenty of good old-fashioned drama on the field as the Padres took advantage of the Dodgers' bullpen in a 6-3 win in front of an announced crowd of 52,136 at Dodger Stadium.

In relief of starter Chad Billingsley, who left with the score tied after six innings, reliever Ronald Belisario walked the eventual winning run to begin the seventh inning.

After a single, another walk and a pitching change, Paco Rodriguez walked in a run to give the Padres a 4-3 lead before a double-play groundball scored an insurance run.

Dodgers manager Don Mattingly was less concerned with the relief pitching and more focused on the team leaving nine men on base.

"I'm not happy with the bottom line of what's going on, but we're getting plenty of baserunners," Mattingly said. "If we continue to get that kind of traffic, we're going to score plenty of runs."
