SAN DIEGO -- The last time that Padres reliever Nick Vincent did his job well, he found himself on a plane back to Triple-A Tucson.
"It's part of the game," Vincent said on Tuesday.
Vincent was added to the roster before Tuesday's game against the Braves with pitcher Burch Smith on his way to Tucson, where he'll rejoin the starting rotation.
Vincent gives the Padres a fresh arm in the bullpen and someone with Minor League options, meaning he could find himself on the way back to Tucson if he's pressed into duty.
That's what happened when the Padres needed 17 innings to defeat the Blue Jays on May 31, a contest that saw Vincent throw 36 pitches over three scoreless innings, his longest stint since 2010.
"It was a fun game," Vincent said.
Vincent was optioned back to Tucson the following day as the Padres, in need of a fresh arm, promoted left-handed reliever Tommy Layne.
"It's not that disappointing … you know you did your job and helped the team win," Vincent said.
Vincent made four appearances with Tucson and didn't allow a run in 3 2/3 innings with no walks and seven strikeouts. Vincent was 4-0 with a 1.64 ERA in 11 appearances in May for Tucson.
Vincent might have been a part of the Opening Day roster had he not developed an inflamed tendon in his lower right forearm near the end of Spring Training. He said it wasn't until the end of April when he finally felt like himself again
Smith joined the Padres on June 8 from Tucson but didn't make an appearance.
Maybin out minimum of six weeks with PCL damage
SAN DIEGO -- Padres center fielder Cameron Maybin will miss a minimum of six weeks after suffering damage to the posterior cruciate ligament in his left knee, general manager Josh Byrnes confirmed on Tuesday.
Maybin injured his knee after landing on it while attempting a diving catch of a fly ball that Rockies third baseman Troy Tulowitzki hit in the eighth inning Sunday at Coors Field.
"I've taken a lot of bumps, lot of bruises, lot of big hits over my career playing outfield. ... I just thought it was one of those things that I'd be able to shake off. I was actually ready to go today if it was a possibility," said Maybin. "But, unfortunately, the MRI results we got back said I tore my PCL, so it's something I got to deal with."
Maybin was 5-for-18 with a home run, four RBIs and four stolen bases in four weekend games against the Rockies since returning from the disabled list on Thursday. Maybin previously missed 45 games with a right wrist impingement.
For the season, Maybin is hitting .157 with one home run and five RBIs in 51 at-bats.
Mark Kotsay was in the lineup Tuesday in right field and Will Venable was in center. On Monday, Alexi Amarista got the start in center field.
The Padres might not need to add an outfielder to their 25-man roster, as they have seven players who can handle the three outfield positions.
Headley involved in 'Tribute for Heroes' campaign
SAN DIEGO -- Mary Ann Holman, Josh Hooker and Nick Kimmel are the Padres three finalists in the "Tribute for Heroes" campaign, a national initiative by Major League Baseball and People magazine that recognizes military veterans.
The field has been narrowed down to 90 nationwide, three from each team, and fans are encouraged to visit TributeForHeroes.com to vote on their favorite stories until June 30.
One winner from each team will be included in the festivities during All-Star Week and recognized on July 16 before the 2013 All-Star Game at Citi Field.
Third baseman Chase Headley was among the guest panel that had the unenviable task of narrowing down the field to 90.
"I read the first three and I was like, 'I'm supposed to narrow this down?'" Headley said. "It's very difficult, because everybody you looked at, you feel like they deserved to receive that honor, to go to the All-Star Game and be on the field and all that stuff.
"It was tough. I just sat down with [wife] Casey, sort of reviewed everything, talked about all the accomplishments, what they've been through, what opportunities they have had in the past to get to do something like this. There is really no good way to do it, because they are all such worthy candidates."
Holman became a member of Team Red White and Blue -- an organization that connects veterans to their community through physical and social activity -- after being discharged from the Navy. She is also a member of Team Rubicon Region 8, a veteran group that works as a disaster relief team.
Hooker served as an Army Scout team member after enlisting right after his high school graduation. While in Iraq in 2006, his vehicle was struck by an Improvised Explosive Device, killing his good friend and mangling his left leg. That leg is amputated below the knee, and Hooker now does some volunteer work in the community and is a local high school football coach.
Instead of pursuing a baseball scholarship at Arizona State University, Kimmel enlisted in the Marine Corps in 2008. In his second deployment to Afghanistan, he step on an IED, losing both legs above the knee and his left arm above the elbow. He's is able to weld, drive a car and snowboard with the help of his high-tech X2 legs, and he returns to his high school to talk to the high school drafting and welding class about those legs. He has been awarded the Purple Heart, a Combat Action Ribbon and a Navy Achievement Award.
• Double-A San Antonio will have seven players participate in the Texas League All-Star Game on June 25 in Springfield, Ark. Three players are in the starting lineup for the South -- Outfielders Rico Noel, Reymond Fuentes and third baseman Jake Blackwood. Jeudy Valdez made the team as a reserve infielder. Pitchers who made the team include Matt Andriese, Matt Stites and Kevin Quackenbush.
• Closer Huston Street, on the disabled list since May 30 with a left calf strain, will pitch one inning on Wednesday for Class A Lake Elsinore. Manager Bud Black said there's no set plan for when he'll pitch again, though it's not inconceivable that he could return when eligible on June 14.
