Mike Cameron, Red Sox Bullpen, Keys to 4-2 Win Over Giants SAN FRANCISCO — Mike Cameron hit a
three-run homer, Darnell McDonald also connected and the Boston Red Sox
beat the San Francisco Giants and their top pitching prospect 4-2 on

Scott Atchison (1-1) tossed 2 1/3
innings for the win against his former team after Boston starter Clay
was removed early because of a hyperextended left knee that he
hurt while running the bases.

The Giants called up Madison Bumgarner
(0-1) from Triple-A Fresno to make his 2010 debut and second career
start. He struck out five and allowed four runs on five hits in seven
innings, but had to throw a lot of pitches to get through Boston's
dangerous lineup. He didn't get much help from the offense, either.

Buster Posey drove in both Giants runs,
but that wasn't enough as Boston bounced back to even the series
following a 5-4 loss Friday night.

Along with his first home run in a
season that featured more than a month on the disabled list, Cameron
crashed into the wall to make a great catch of Pablo Sandoval's fly to
end the eighth.

Jonathan Papelbon worked a 1-2-3 ninth
on eight pitches for his 17th save in 20 chances.

Only a few hours after the Red Sox
placed All-Star second baseman Dustin Pedroia on the 15-day disabled
list with a broken left foot, they lost Buchholz. Going for his 11th
win, he was removed after only one inning.

Buchholz singled in the top of the
second and was apparently injured moments later running between first
and second on Marco Scutaro's inning-ending double play. Buchholz,
Boston's only pitcher with double-digit wins, grabbed his left hamstring
in the dugout.

In the middle of the game, the Red Sox
announced they had acquired infielder-outfielder Eric Patterson from
Oakland for minor league pitcher Fabian Williamson.

Getting Patterson gives Boston some
added depth with Pedroia out. Patterson was set to join the team Sunday,
an easy trip considering the A's are playing at home across the bay
against the Pirates.

The 20-year-old Bumgarner was
scratched from a scheduled start Friday night for Fresno at Portland in
case the Giants needed him Saturday. With Posey getting a rare start
behind the plate, San Francisco had two of its top rising stars in the

Posey had an RBI groundout in the
fourth and a sixth-inning sacrifice fly.

Bumgarner walked just one batter in a
96-pitch outing and singled leading off the fifth for his first major
league hit.

The left-hander, who went 7-1 with a
3.16 ERA in 14 Triple-A starts this season, is expected to remain in the
rotation as the Giants try to find some consistency from their No. 5
starter. Todd Wellemeyer isn't close to returning from a strained right
quadriceps that sidelined him June 11 and should keep him out until the
All-Star break or longer.

Bumgarner took the mound shortly
after the Giants retired the No. 20 of 91-year-old Hall of Famer Monte
— with Hall of Famers Willie Mays, Willie McCovey, Juan Marichal,
Gaylord Perry
and Orlando Cepeda on hand — offering quite a glimpse of
Giants past and future.
