ST. PETERSBURG -- Left-handed pitcher Aaron Poreda, a key component in the trade that sent Jake Peavy to the White Sox last July, has been pitching well since he earned a promotion from Double-A San Antonio to Triple-A Portland.
In his last outing on Saturday, Poreda struck out three and didn't walk a batter over three scoreless innings.
Overall, Poreda hasn't allowed a run in Portland in four appearances. In 7 1/3 innings, he has allowed three hits with seven strikeouts and seven walks.
The walks -- and command, in general -- are a big reason Poreda began the season with San Antonio. He had a 2.52 ERA there with 25 strikeouts and 26 walks in 25 innings.
Still, there's no denying that Poreda has electric stuff, as Randy Smith, who is the Padres director of player development, said recently.
"Guys look uncomfortable hitting against him," Smith said of Poreda.
Between San Antonio and Portland, opponents are hitting .191 against Poreda in 2010.
