Wieters returns to lineup after birth of son

BALTIMORE -- Orioles catcher Matt Wieters was back in Saturday's starting lineup a day after his wife, Maria, gave birth to the couple's first child, a son named Maverick Luther.

Asked if he had gotten any sleep, Wieters -- who came right from Greater Baltimore Medical Center to Camden Yards Saturday afternoon -- said yes.

"The first night, not much at all, but last night I was able to scrap together five, six, eight hours there somewhere, so I feel good today," Wieters said.

The original plan was for the couple to induce labor on Thursday's off-day, and that did occur, but Maria was in labor for about 23 hours, with Maverick arriving at 5:11 a.m. Friday. And yes, the Orioles' game was on in the hospital room, making it easier for Wieters to be away from his teammates.

"No sympathy for me -- catching 18 innings was a lot easier than what [Maria] had to do," Wieters said, smiling. "I'd probably have to catch three-in-a-row-18-inning games to equal that."

Asked about the name, Wieters said it wasn't a family name, but they wanted to keep with the "M" theme and try to find something unique.

"I think my mother-in-law mentioned it one day and it just rang as something that was a pretty cool name," he said. "No 'Top Gun.' I find it hard to find a non-cool Maverick."

Hammel to pitch in simulated game on Monday

BALTIMORE -- Orioles pitcher Jason Hammel will throw a four- or five-inning simulated game at the team's fall instructional league in Sarasota, Fla., on Monday as the 30-year-old inches closer to a return.

Orioles manager Buck Showalter hasn't eliminated the possibility that Hammel could pitch in a postseason game even if he doesn't appear in another regular-season game, and the right-hander could line up for later in the week.

"We talked about that," Showalter said Saturday afternoon. "We had a little staff meeting today with the coaches, and instead of trying to handicap it, we left it, 'Let's see what Monday brings.' ... We will step back and see what our needs are from our pitching. Probably something that won't be decided until Tuesday, [after we] see how he feels from the outing."

Hammel, who has been sidelined with right knee discomfort, threw another bullpen session Friday afternoon with no problems. He has been wearing a knee brace, joking it's his best Dan Marino impersonation, and he will face both left-handed and right-handed hitters Monday, with pitching coach Rick Adair scheduled to be in attendance and Steel Russell -- son of bench coach John Russell -- catching.

The team's best starter when healthy, Hammel aggravated his surgically repaired knee in his second start back from the disabled list on Sept. 11. He is 8-6 with a 3.43 ERA in 20 starts.
