The Phillies scored only two runs on five hits combined during two consecutive losses to the Miami Marlins. Jump-starting the offense won't be easy Monday night when they open a three-game series in San Francisco against the Giants.

The Phillies will face 23-year-old lefthander Madison Bumgarner, who is off to a sizzling start.

Bumgarner, who is 2-0 with a 0.00 career record in two World Series games, is 3-0 with a 1.55 ERA this season.

He has not allowed more than two earned runs in any of his six starts. And of course he is lefthanded: The Phillies are batting .207 against southpaws this season.

No matter whom the Phillies are facing, manager Charlie Manuel knows that the team has to pick it up offensively.

"We will struggle until we start hitting the ball better and making better contact and doing things," Manuel said after Sunday's 14-2 loss to the Miami Marlins at Citizens Bank Park.

Manuel said the Phillies need to hit for power. They entered Sunday 10th in the National League in slugging percentage. After Sunday's loss, their slugging percentage is .374.

"With the lineup we have, we better hit extra-base hits because we don't have a whole lot of speed right now," Manuel said.

Halladay's woes

More numbers from Roy Halladay's disappointing run:

On Sunday he allowed nine runs, five in the first inning. According to ESPN, it was the first time he had allowed five or more runs in the first inning of a game since April 29, 1999, at Anaheim when he was pitching for Toronto.

He has allowed 17 earned runs in his last two starts after surrendering nine Sunday. That total was the highest in consecutive starts in his career. Previously he had allowed 16 earned runs in consecutive starts three times.

Halladay had pitched fewer than four innings in three of 90 starts over his first three years with the Phillies. After going 2 1/3 innings on Sunday, he has done so in four of his seven starts this year.

Rare walks

Phillies centerfielder Ben Revere tied a career high with two walks Sunday. He had done it twice previously with the Minnesota Twins.

With Revere's speed, getting walks should be more of a priority. This season he has struck out 15 times and walked just seven times.
