1B Yonder Alonso needs more at-bats at Triple-A Tucson before his return to the club, manager Bud Black said. "He's still got to get his timing and his game stamina. When he comes back I want him to feel like he's been playing. Two games for me (isn't) adequate enough for the time he's missed." Alonso went 2-for-4 on Wednesday night in another rehab start with Tucson. Alonso has six hits in his last eight at-bats with Tucson. He is expected to rejoin the Padres during the upcoming series with the San Francisco Giants.
RHP Sean O'Sullivan will start Friday's game against the Giants. O'Sullivan has a 7-4 record with a 3.88 ERA in 18 starts at Triple-A Tucson. "He's pitched very well with Tucson and he had a good spring training for us," manager Bud Black said.
