Friday's contest between the Giants and Padres at Petco Park will be quite a homecoming for right-hander Sean O'Sullivan, who will make his first start as a member of the Padres.
Born and raised in San Diego, O'Sullivan grew up rooting for the Padres and played at Valhalla High School and Grossmont College.
"A dream come true is the only way I can describe it," O'Sullivan said. "I always dreamt as a little kid about putting this uniform on, so it's a special day."
O'Sullivan will see his first big league action since a start Sept. 27, 2011, with the Royals. He has made 34 career starts in the Majors with the Angels and Royals.
In 18 starts with Triple-A Tucson this season, he went 7-4 with a 3.88 ERA, including a 6-2 record and 3.21 ERA in his last 12 starts.
"It's hard not to want to do so well," O'Sullivan said. "I'll try to put that as far back in [my mind] as I can and go out there and play baseball."
Meanwhile, former Padre Chad Gaudin (2-1, 2.44 ERA) will make his sixth start since joining the Giants' rotation.
A boost to the staff in his five starts, Gaudin has allowed more than two earned runs only once. He's 2-6 with a 5.30 ERA in his career at Petco Park, but has allowed just one run in four innings against San Diego this season.
The right-hander received a no-decision in his previous outing against the Dodgers, allowing just one earned run on four hits, while fanning a season-high nine.
"Guys that compete like that you always want on your team," Giants catcher Guillermo Quiroz said after the game. "He located everything. He went right at people with his fastball and mixed in his changeup and curve."
In eight career appearances (one start) against the Padres, Gaudin is 1-0 with a 1.72 ERA.
Giants: Pence finishes third in Final Vote
San Francisco right fielder Hunter Pence came in third in the National League All-Star Final Vote.
He finished behind Atlanta first baseman Freddie Freeman and Los Angeles outfielder Yasiel Puig and ahead of Washington shortstop Ian Desmond and Dodgers first baseman Adrian Gonzalez.
"All five of us are deserving. I'm happy for Freddie," said Pence, a two-time All-Star with Houston. "This is his first [All-Star Game], so that makes it more special."
• Ryan Vogelsong threw a bullpen session at Petco Park on Thursday for the first time since breaking the pinkie finger on his throwing hand. He threw 30 pitches, all fastballs, and reported that he was sharper than he would have felt during a comparable session early in Spring Training.
Padres: Alonso expected to return from DL
First baseman Yonder Alonso is expected to be back in the Padres lineup Friday after missing 34 games with a broken bone in his right hand.
Manager Bud Black said there's a "high probability" Alonso will be reinstated from the disabled list in time to start the game.
Alonso, who landed on the DL on June 6 (retroactive to May 31), played in his fourth Minor League game with Triple-A Tucson on Thursday as part of his rehab assignment.
"Physically, he's doing well," Black said. "The hand is fine, there's no pain. The swings are better. He's gotten some hits, not a lot of them hard contact. But he swung the bat better last night, he used his lower half and it's much more indicative of the swings we expect when he comes back."
• In one career start against the Giants, O'Sullivan tossed seven innings and allowed one run on five hits for the win.
• The Giants are just 12-18 in the first game of a series this season, losing nine of their last 11.
