LOS ANGELES Rookie right fielder Yasiel Puig hit his seventh home run in his 20th major-league game and added a tiebreaking RBI single in the eighth inning, leading the Los Angeles Dodgers to a 3-1 victory over the Giants on Monday night.
Nick Punto, who replaced third baseman Juan Uribe in a double switch, led off the eighth with an opposite-field double down the right-field line. Mark Ellis sacrificed Punto to third and reached safely when Giants starter Madison Bumgarner threw high to first for an error.
Puig greeted reliever George Kontos with a line-drive single to left that scored Punto. Hanley Ramirez drove in the final run on a liner toward the middle that shortstop Brandon Crawford knocked down with a lunging attempt before getting the out at first.
It was a day full of bad news for the Giants, as they revealed that center fielder Angel Pagan is scheduled for left-hamstring surgery today and could miss the rest of the season.
The procedure to repair the tendon will be performed by Dodgers team physician Neal ElAttrache at the Kerlan-Jobe Clinic in Los Angeles, and Pagan is expected be out at least another 12 weeks.
Pagan, who turns 32 on July 2, signed a four-year, $40 million contract in December after helping the Giants win their second World Series title in three years. He is batting .262 with three home runs and 24 RBIs.
Gregor Blanco and Juan Perez, who was promoted from the minors on June 7, have shared time in center with Pagan out. Blanco started the series opener in Los Angeles.
Also Monday, the Giants recalled Kontos from Triple-A Fresno and optioned right-hander Jean Machi to their Pacific Coast League club. Right-hander Chad Gaudin was placed on the 15-day disabled list because of a bruised elbow, and left-hander Mike Kickham was recalled from Fresno.
Pagan hasn't played since his inside-the-park homer lifted San Francisco to a 6-5 victory over the Colorado Rockies on May 25.
He sustained a small tear when he aggravated the leg injury during a rehab game with Class-A San Jose on Thursday night. He then met with team orthopedist Dr. Ken Akizuki and opted to get a second opinion.
"After getting the second opinion, the consensus was that surgery's the best option right now," Giants manager Bruce Bochy said.
Meanwhile, the Giants reinstated slugging third baseman Pablo Sandoval from the disabled list after he missed 14 games because of an injured left foot. Sandoval started and went 2 for 4.
Kontos was optioned to the minors on June 11, the day he received a three-game suspension for throwing a pitch at Pittsburgh's Andrew McCutchen. Kontos is appealing the penalty and is eligible to play until his case is heard by Major League Baseball.
