OAKLAND -- Brad and Sue Peterson have had quite the busy week and a half. First the Temecula, Calif., residents were in Sacramento to see their son Shane open the season with the Triple-A River Cats. Then, when it appeared A's first baseman Brandon Moss might go on the paternity list April 4, they hopped a flight to Houston, where Shane was headed in case the A's needed to replace Moss on the active roster. Only Moss' wife did not go into labor, and Moss returned the next day, meaning Shane was never officially called up.
Peterson returned to Sacramento and his parents returned home until this morning, when Moss was officially placed on the paternity list and Peterson officially called up. They hopped in the car, Peterson said, and made the drive up to Oakland, where Peterson is in the A's lineup tonight, batting eighth and playing first base in his major-league debut.
"It's been a long few travels for them," Peterson said with a grin. "But obviously it's worth it for them."
Peterson, a second-round draft pick of the St. Louis Cardinals in 2008 out of Long Beach State, has played in 529 games in the minors. He opened eyes in spring training with a .408 average (20-for-49) and has not stopped hitting since reporting to Triple-A, batting .410 with five doubles and seven RBIs in 11 games with the River Cats.
"I'm feeling pretty good, trying to keep the confidence up, trying to stay within myself and not make too many adjustments," Peterson said. "I've been going good, so I don't want to over-adjust, don't want to do too many things."
Peterson has played mostly outfield in the minors but said he has taken more ground balls lately anticipating filling in for Moss at some point. Manager Bob Melvin said he hadn't yet heard whether Moss' wife has given birth, but that birth was supposed to be induced this morning. Melvin said he expects Moss to miss tomorrow's game before rejoining the A's for their flight to Tampa Bay on Thursday's off day.
*** UPDATE, 7:50 p.m.: The A's announced that Moss' wife gave birth this afternoon at 3:42 p.m. to a boy weighing 7 pounds, 9 ounces.
That means it could be a short call-up for Peterson, but that didn't dim his excitement prior to tonight's game, especially after the false start in Houston. He said he had never even been to the Coliseum before this afternoon.
"If it would've taken me 500 games, five games, 5,000 games, it means a lot just to be here," Peterson said. "Who knows how long it's going to be, but I'm just trying not to worry about that."
* Here's the full lineup the A's will have against Astros right-hander Brad Peacock, who pitched for the River Cats last year and was sent to Houston over the offseason in the Jed Lowrie trade:
And the Astros' lineup against A.J. Griffin, who will be going for his third win:
* Peacock is 1-1 this year for Houston with a 4.83 ERA. Early last season he appeared in line to be one of the first options for the A's in terms of starting pitching depth. But the ascensions of A.J. Griffin and Dan Straily, along with some struggles from Peacock, changed that. Peacock was 12-9 with a 6.01 ERA for the River Cats last season.
"He's got a chance to be a good starter, there's no doubt," Melvin said. "He's got a live fastball that has good four-seam spin to it, a good curveball that he throws in any count, working on a changeup. I think it's just confidence and believing in himself on a big-league level. He's got good stuff."
* A's infielder Adam Rosales (strained intercostal) was out taking early ground balls and making throws to second base. Melvin said Rosales "looks good," and if he comes out of today's work feeling good he could start a rehab assignment as early as tomorrow.
