As is the case for a handful of his Philadelphia teammates, A.J. Burnett's days with the Phillies may be numbered.
Burnett, who has a limited no-trade clause, has been mentioned in numerous trade rumors as speculation heats up in advance of the July 31 non-waiver Trade Deadline. The 37-year-old righty has value for contenders, with a 6-9 record and 4.08 ERA in 21 starts this season. He posted a 2.94 ERA in seven starts before struggling in his last outing. He faces the Giants on Wednesday.
"I signed here to play here," Burnett told a reporter recently. "I'm not a guy who looks for an out or wants to get out because things aren't going the right way. If that happens, then it happens, but I'm not looking to move on. This is my team. I understand how things work, but I'm trying not to worry about it. I just try to go about my business and enjoy my teammates."
There wasn't much for them to enjoy about his last start, as he was chased from the game after allowing six earned runs on 10 hits in five innings. Wednesday will be his first start against San Francisco in 2014; he's 6-3 with a 2.30 ERA in nine career starts against the Giants.
He'll be opposed by All-Star lefty Madison Bumgarner, who resembled his usual All-Star form in his last start, when he gave up one run on four hits in six innings against the Marlins last Friday. He gave up 19 earned runs in 24 1/3 innings in his four previous starts.
The lone blemish in Bumgarner's previous outing was a home run to Marlins slugger Giancarlo Stanton, who crushed an 0-1 curveball. ESPN's Home Run Tracker measured the drive at an estimated 466 feet.
"He was on top of his game," manager Bruce Bochy said of Bumgarner. "With the position we had him, it allowed me to give him a break, because he was really the one guy going without any added rest."
Wednesday's start will be Bumgarner's first against the Phillies this season. He's 1-2 with a 4.05 ERA in three career starts against Philadelphia.
Phillies: Ruf returns to Majors
After a short stint in the Majors earlier this year, Darin Ruf was granted another crack at big league action after the Phillies recalled him from Triple-A Lehigh Valley before Tuesday's game vs. the Giants.
John Mayberry Jr. was placed on the 15-day disabled list with left wrist inflammation to make room for Ruf.
Ruf was first called up in late May, and the Phillies toyed with the idea of implementing a platoon situation at first base between Ruf and Ryan Howard, who struggles against left-handed pitching.
But after Ruf went just 1-for-10, the Phillies ended any chance of that scenario playing out by sending him back down to Lehigh Valley. Shortly thereafter, Ruf suffered a left wrist fracture sliding into a wall while trying to chase down a foul ball. The injury forced him onto the DL on June 4, and he only returned to game action July 2.
In his last three games with Lehigh Valley prior to his callup Tuesday, Ruf went 6-for-12 with four RBIs.
"It's gotten better," Ruf said of his timing at the plate. "Felt a lot more comfortable in the box the last few days."
Giants: Homegrown players abundant
San Francisco's 7-4 victory against Philadelphia on Monday ended with the Giants using an infield consisting entirely of homegrown players: first baseman Adam Duvall, second baseman Ehire Adrianza, shortstop Brandon Crawford and third baseman Pablo Sandoval. Tuesday, manager Bruce Bochy started an infield produced entirely by the Giants system, with Buster Posey playing first base and Joe Panik at second.
San Francisco also employed a homegrown starting infield a handful of times earlier this year: Brandon Belt or Posey at first base, Adrianza or Panik at second base, Crawford at shortstop and Sandoval at third. For most of the season, however, at least one player nurtured in a different organization -- such as Michael Morse, Brandon Hicks or Joaquin Arias -- has joined the infield alignment.
"It's a proud moment for your player development and scouting staffs," Giants assistant general manager Bobby Evans said of the homegrown infield. "They pour hours that nobody sees into preparing the organization for the future. It is very gratifying to fill out your lineup with players from your system. It's a significant accomplishment, especially when it gets to the point where that's the group you go with every day. Any general manager will tell you that's something he's proud of."
• Grady Sizemore needs one hit to reach the 1,000-hit plateau for his career.
• The Giants are 41-15 when they hit at least one home run.
