Grandal hit .230/.342/.382 with 11 home runs in 107 career games at Petco Park, his home ballpark from 2012-2014. The switch-hitter has hit .251/.351/.424 with 14 home runs in 120 games elsewhere.
He is off to a slow start this season, just 6-for-36 (.167) with a home run and six walks, including 4-for-30 (.133) with a home run and six walks hitting left-handed.
The catching split has worked itself out in the first 2½ weeks of the season, with Grandal starting 10 of the first 15 games, including two games in every three-game series so far. But with A.J. Ellis still dealing with taking a ball off his right hand on Wednesday, it is still unknown how much he will be available this weekend.
The lineup is pretty much the regular lineup for the Dodgers, including Juan Uribe at third base.
The Padres made a move before the game, placing Shawn Kelley on the 15-day disabled list with a left calf strain, and recalled right-hander Kevin Quackenbush from Triple-A El Paso.
