SAN DIEGO -- Jason Marquis will become the 10th different starting pitcher used by the Padres when he makes a start Thursday against the Giants at Petco Park.
The Padres signed the 33-year-old Marquis to a Minor League contract last month. He then made one start for Double-A San Antonio on May 31, allowing one run and getting 10 ground-ball outs in seven innings.
The Padres were in need of a fifth starter, and by promoting Marquis -- the roster move becomes official Thursday, as will the corresponding move -- they were able to give some of their starting pitchers one additional day of rest.
"We're excited to have him take the ball," Padres manager Bud Black said. "He's a veteran guy who knows how to pitch. He's excited about this opportunity. It's a situation for him to get a fresh start."
Marquis, who is 3-2 with a 2.93 ERA in six starts at Petco Park, sounded appreciative for the fresh start. It's already been a trying year for him, and not just on the baseball end, where he was 2-4 with an 8.47 ERA in seven starts before being designated for assignment by the Twins in May.
Marquis missed two weeks of Spring Training tending to his 7-year-old daughter, Reese, who was badly injured in a bicycle accident on Long Island.
Reese Marquis suffered a wound from below her chest to her belly button in the accident. She also had internal bleeding and a collapsed lung and was in a Staten Island hospital for 18 days, nine of which were spent under heavy sedation.
She's doing fine now, Marquis said Wednesday.
"I'm grateful for the opportunity the Twins gave me, on the field and in order to spend time with my family," Marquis said. "People tend to do good things in bad situations. But her recovery has been amazing. That's a testament to her."
Marquis said that, for obvious reasons, he wasn't able to "hone his craft" while he was at home during Spring Training. But since the Twins cut him loose, he's been able to make some mechanical changes that he hopes will serve him well moving forward.
With Marquis starting Thursday, Black said his rotation for an upcoming three-game series in Milwaukee that starts Friday would be Edinson Volquez, Eric Stults and Anthony Bass.
Outfielder Will Venable, who left Sunday's game with a strained right oblique, is doing better but is still likely a few days from returning to the lineup. "He's getting better," Black said.
