ST. LOUIS -- Shane Loux considers himself a bit of utility man in the Giants' bullpen. Whether his services are needed as early as the first inning or to get the final out of the ninth, Loux is ready to go whenever.
So was the case Sunday in Colorado as Loux warmed up in the first inning with Tim Lincecum venturing through a 36-pitch first frame. Loux sat down and ultimately relieved Jeremy Affeldt with two out and two men on in the ninth.
Loux used two pitches to seal the Giants' 8-3 victory in his first ninth-inning appearance in more than a month.
"We're using guys in their roles," Loux said. "Guys are doing their jobs and my job is to pitch when asked. It doesn't really matter if it's the first inning or then. Basically, the bottom line, they asked me to get an out and I came in and threw sinkers."
Loux was activated off the disabled list Thursday and had been shelved since June 26 with a neck strain. The 32-year-old right-hander said he's been doing more balanced workouts recently -- rather than focusing on building strength -- to make sure his body is ready to perform.
With many roles in the Giants' bullpen clearly defined, Loux prepares himself to handle any situation that other San Francisco relievers aren't already expected to be called upon for.
"For guys like me, my role is to pitch where they're not," Loux said, "whether it be eat innings early or cleaning up the last couple innings in a lopsided game. Whatever that role is when you don't want to burn arms, that's my role."
Giants add left-hander Mijares to bullpen
ST. LOUIS -- The Giants claimed reliever Jose Mijares off waivers from the Royals on Monday. The 27-year-old Mijares, who appeared in 51 games for Kansas City this season, gives San Francisco another left-handed option out of the 'pen.
"Good arm ... has thrown the ball very well," said Giants manager Bruce Bochy. "He's the type of guy we think can help this club."
Mijares owns a 2.56 ERA in 38 2/3 innings this season. He's given up four earned runs over his last four outings, spanning an inning of work. That rough patch ballooned Mijares' ERA, but he'd given up one earned run in 22 games prior to stretch, dating back to May 30.
Bochy said Mijares will likely be used as a lefty specialist. Left-handers are batting .214 with 21 strikeouts in 84 at-bats against Mijares this season. Bochy added that having Mijares will free up more opportunities to use fellow left-hander Jeremy Affeldt in save situations.
Bochy said Mijares could possibly join the club in St. Louis as early as Tuesday.
Theriot relishes return to St. Louis
ST. LOUIS -- Ryan Theriot only spent a year in St. Louis, but he made it count.
Theriot, who signed with the Giants as a free agent this year, hit .271 in 132 games as the Cardinals won their 11th World Series title and the first of Theriot's career. On Monday, Theriot returned to St. Louis for the first time this season as the Giants take on the Cards for a four-game series.
"It's great, man," Theriot said. "St. Louis was an awesome time. Obviously we had some great success last year. It's good to see those guys. It's going to be fun, a good series."
The series will be the only one in St. Louis between the Giants and Cardinals this season. Theriot spent time catching up with former Cardinals teammates before Monday's game and said he tries to keep in touch with many of them throughout the season.
Despite putting up some better numbers in a couple of years with the Cubs, Theriot called his 2011 season the best of his career as he'll always cherish winning a championship.
"Not many people can say they've won a World Series even if they ever get a chance," Theriot said. "It's a very special place and it always will be for me and my family."
Buster Posey's mobile app game, Buster Bash, was released Monday and is available for a free download from the iTunes App Store. The game follows Posey's playing career from his days as an aspiring player in Leesburg, Ga., all the way up to his days with the Giants.
The Giants entered Monday having won eight of their last 12 games on the road and are 27-26 (.509) on the road this season. That ranked as the fourth-best winning percentage on the road in the National League.
