Respect runs deep between Giants manager Bruce Bochy and A's manager Bob Melvin.
Said Melvin: "I've managed against him for quite a while. He's probably the best manager in baseball right now. ... They have a lot of confidence as a team and that comes from their manager."
Said Bochy: "The roll they went on last year, that's pretty impressive. [He was] a well-deserved Manager of the Year."
The two Bay Area skippers match wits again Tuesday in the final game between the two clubs in Oakland. They'll head to San Francisco to conclude the home-and-home Interleague series with games Wednesday and Thursday.
Southpaw Michael Kickham, 24, will make his big league debut for the Giants, replacing the injured Ryan Vogelsong in the rotation after the right-hander fractured his hand his last time out. In 10 starts for Triple-A Fresno, Kickham was 3-4 with a 4.33 ERA, but he's posted a 1.72 mark in his last five outings.
"His stuff is good," said Giants catcher Guillermo Quiroz, who caught the left-hander in Spring Training. "He was working on a changeup in Spring Training and has a good fastball and slider."
The Giants won't have to tinker with their bullpen as Chad Gaudin, who was also a candidate for Vogelsong's vacated rotation spot, will stay in the 'pen. As for the A's, they'll be tasked with the challenge of facing a pitcher for the first time.
"It's going to be more scouting and video that we can get," Melvin said. "From what I understand, he's a guy who has been hot recently, but he's a guy that we don't know."
Opposite Kickham will be A's right-hander Jarrod Parker (2-6, 5.76 ERA). In his last start Wednesday, Parker surrendered a pair of first-inning home runs, but he shut out the Rangers' offense over the next six frames.
Parker had a dreadful opening month, but he has lowered his ERA by almost two points in May thanks to three consecutive quality starts.
Giants: Casilla set for surgery
San Francisco reliever Santiago Casilla will undergo leg surgery Tuesday to remove a cyst in his right tibia.
Casilla is hopeful to return to the club after the All-Star break.
• Everyday second baseman Marco Scutaro will get a day off in the field Tuesday, instead assuming the designated-hitter role.
A's: Reddick on the mend
Oakland right fielder Josh Reddick will continue his rehab assignment Tuesday, heading to Triple-A Sacramento for what will likely be the first of three games there.
Reddick was slated to play at Class A Stockton on Monday, the first game in his recovery from a right wrist injury that landed him on the disabled list on May 8.
"We're looking at probably four [rehab games] right now," Melvin said Monday.
• Parker has made one start in his career against the Giants, tossing six innings of four-hit, one-run ball before the bullpen lost the game for Oakland.
• The Giants have not yet won a game in Interleague Play this season, after dropping two games earlier this month in Toronto.
• The A's saw two left-handed starters in their weekend series against Houston, and in the four games this week against San Francisco, three Giants lefties will take the hill.
