Work will begin this week to bring in the fences in right field and left-center at Petco Park.

The visitor's bullpen will also be moved from right-field foul territory to behind the home bullpen beyond the fence in left-center.

Petco Park has long been considered a pitcher's park that eats up many long fly balls.

"We want the park to play the right away for players and for the fans," Padres president and CEO Tom Garfinkel said. "That was driven first by baseball operations in terms of the right way to construct the dimensions to make it more fair for players. Players know what's fair and what's not. When they crush a ball that would be out in 29 other parks, and it's not out here, they know that it's not fair. We wanted to make it more fair from that standpoint."

From the right-field porch to the right-center gap, the fence will be moved in from 402 feet to 391 feet and lowered to match the rest of the outfield wall.

In left-center, the fence will be moved in from 402 feet to 390 feet to allow for the visiting team's bullpen to be relocated.
