"We're just praying that the radiation is going to knock it out and that he's not going to have too much of a rough time with the treatments," said Vogelsong, who surrendered one hit and struck out four in three shutout innings as the Giants endured their third consecutive Cactus League tie, an 8-8 deadlock.
Vogelsong said that his father had his prostate removed, but doctors found more cancerous tissue in the area during tests last year. Harold Vogelsong informed his son about his condition last year during a visit to San Francisco.
Because of his father's treatment regimen, Ryan Vogelsong's parents won't be able to visit him at Spring Training or see him pitch in the World Baseball Classic.
"They'll watch [on television] intently, I'm sure," said Vogelsong, who has been named Team USA's No. 2 starting pitcher.
The doctors, said Vogelsong, "keep reassuring me that he's going to be fine. ... It's weighing on my mind a little bit, but at the same time, baseball's kind of a getaway."
Vogelsong found his escape against the Angels. He faced the minimum nine hitters thanks to a first-inning double play that erased Mike Trout, who stroked a leadoff single.
The right-hander will face the White Sox on Monday in his final start for the Giants before he leaves the ballclub for the Classic. Vogelsong's initial start for Team USA will be March 9 against Italy. He hasn't let the excitement of performing in the Classic overwhelm him yet.
"I'm still trying to stay more focused on getting myself ready -- not just for that, but for the season as well," said Vogelsong, who's living across the street from Team USA's training site, Salt River Fields at Talking Stick. "I think once I get over there and we start doing our daily stuff with the team, it'll probably hit me a little bit more."
