Yovani Gallardo takes the ball for the Orioles on Wednesday in the finale of a two-game set at Petco Park, against the Padres and Christian Friedrich.
It will mark the first time Gallardo has thrown against a National League team this season, and the first time he's stepped in the batter's box since last September when he pitched for the Rangers against the Padres.
"It will be fun," said Gallardo, who hit 12 home runs over eight seasons as a pitcher for the Brewers. "I think having the opportunity to do it for seven years when I was with Milwaukee, I kind of got used to it after a while. And I enjoyed it."
Baltimore has won both of the games Gallardo has started this June, where he has posted a 4.35 ERA over 10 1/3 innings.
Friedrich will look to bounce back from his last two starts, in which he has allowed 10 earned runs in 11 innings against the Nationals and the Reds. In his first three June starts, when he allowed just five earned runs over 17 2/3 innings.
