The Padres will try to put the first half of the season behind them when they take the field on Friday in St. Louis.
San Diego enters the second half having lost 18 of its last 22 games and will send Jason Marquis to the mound against his former team. Marquis recorded nine victories in his first 14 starts but has stalled there in his last five outings, and still searches for an elusive 10th win.
Marquis has issued the most walks (65) in the Majors, but the Padres aren't concerned about the free passes, especially since Marquis is 9-4 with a 3.77 ERA.
"Some of those walks, I call them 'navigating his way through a ballgame,'" said pitching coach Darren Balsley. "He's stubborn, and he doesn't actually pitch around guys. He's going to throw the ball where he thinks they can't put it in play hard."
Marquis had 12 quality starts in the first half, his most since posting 13 in all of 2011 and nine shy of his career-best 21 in 2009, his lone All-Star campaign. Friday will be Marquis' second start this season against the Cardinals, with whom he spent the 2005-06 seasons.
Starting for St. Louis is Jake Westbrook, who will be making his seventh start since coming off the disabled list in mid-June. He has looked good in his three wins, but he has also dropped three contests, including his most recent -- a 5-4 loss to the Cubs on Thursday in which he allowed three earned runs on seven hits in seven innings.
"I wasn't as sharp as I have been, but I was able to get back in the zone and make some good pitches," Westbrook said. "I felt like I battled and was able to get deep in the ballgame and give us a chance."
Cardinals: Adams steps in for the injured Holliday
With Matt Holliday sidelined due to an injured right hamstring, Matt Adams was called upon to start at first base and Allen Craig was bumped back into Holliday's spot in the outfield on Sunday.
Adams isn't consistently in the lineup but has made the most of his limited opportunities, batting .316 with 26 RBIs and seven homers in just 133 at-bats.
"He does a great job off the bench [or] starting," manager Mike Matheny said. "He's done a nice job defensively. There's just not a whole lot that we've seen not to like. It can be [a tough role], but he's done a terrific job so far. We just want him to keep doing exactly what he's doing."
Padres: Dee returns to become president, CEO
Mike Dee helped develop the Fenway Sports Group with the Red Sox, aided in continued success of the Miami Dolphins franchise and will now return to San Diego, where he worked for the Padres from 1995-2002.
Dee returns as president and CEO. He played an integral role in helping generate public and corporate support that led to the approval and construction of Petco Park, which opened before the 2004 season.
"Mike is the best sports executive I've ever dealt with," said Dan Novak, vice president of global marketing, public relations and communications for Qualcomm. "We were able to collaborate and really focus on a shared vision for what we were trying to create; what's the best thing to do for the customer or the fan."
• Padres All-Star shortstop Everth Cabrera swiped his 33rd base of the season on Saturday night. Those 33 thefts before the midseason break are the second most in franchise history, behind only the 35 stolen by Alan Wiggins in the first half of the 1984 season.
• Cardinals shortstop Pete Kozma was 0-for-28 until his RBI single in the third inning of Sunday night's game against the Cubs. He hadn't had a hit since June 25, but finished Sunday 3-for-6 with a run scored and two RBIs.
