No doubt, Zack Wheeler spent plenty of time dreaming of his AT&T Park debut after he was selected sixth overall by the Giants in the first round of the 2009 Draft.
He just didn't envision doing so as a member of the New York Mets.
On Wednesday afternoon -- nearly two years after Wheeler was traded to the Mets in the Deadline deal that sent Carlos Beltran to San Francisco -- the 23-year-old right-hander gets the ball against the Giants, looking to complete a sweep.
"It's going to be pretty cool to pitch against the organization I was drafted by," Wheeler said. "It'll be fun."
Wheeler, who has posted a 4.29 ERA in four starts this season, has reiterated that he felt flattered to be traded for a player of Beltran's caliber. He also has nothing but love for the San Francisco fans.
"They're awesome," Wheeler said. "They're true, they're loyal, they love the game of baseball, they know the game of baseball, and they're always going to be there to back you up."
That doesn't mean Wheeler won't be doing his best to remind the Giants organization just what they're missing out on.
"I definitely want to go out there and do well for myself and maybe show them what they could have had, I guess," Wheeler said. "That would be fun."
Taking the ball for San Francisco will be right-hander Matt Cain, in the midst of arguably his poorest big league season. Every time Cain has appeared to turn a corner this year, he has taken a step backward, as witnessed by the eight runs he allowed in 2 1/3 innings against Los Angeles on Friday.
Prior to that start, Cain had worked five outings in which he posted a 1.82 ERA. He's hoping the poor outing in Los Angeles was just a blip on the radar.
The Giants hope so as well. They've looked almost nothing like the reigning World Series champs, having gone 2-13 in their past 15 games. The poor stretch has dropped them to last place in the National League West -- the division they led as recently as May 26.
Mets: Marcum out for year
Mets right-hander Shaun Marcum will undergo season-ending surgery for thoracic outlet syndrome Monday. He experienced numbness in his right hand Saturday night in a start against Milwaukee.
"The two courses of treatment would be conservative -- which would be rehab -- or surgery," assistant general manager John Ricco said. "And Shaun has opted to have the surgery. And that is the recommendation of our doctors as well."
The club called up right-hander Gonzalez Germen from Triple-A Las Vegas.
Giants: Francoeur to SF
Outfielder Jeff Francoeur inked a Minor League contract with the Giants on Tuesday afternoon after he was released by Kansas City on Sunday.
Francoeur, who hit just .208 with a .249 on-base percentage with the Royals, will spend a stint with Triple-A Fresno before the Giants are hopeful he can return to the Majors.
"He has a history of outfield duty and has done some good things with the bat," manager Bruce Bochy said.
• Mets All-Star third baseman David Wright has hit Cain hard in his 27 career plate appearances against the right-hander. He is batting .458 with a .519 on-base percentage and six doubles.
• In their last 17 games, the Giants are batting .128 with runners in scoring position, including a current stretch of 6-for-64.
• On the season, the Mets are 22-21 away from Citi Field, the third-best mark in the NL. In their last 10 road series, including the current one, they've gone 7-1-2.
