LOS ANGELES -- Cubs pitchers Andrew Cashner and Randy Wells headed to Arizona on Wednesday to continue their rehab there and both could be facing batters next week.

Cashner, sidelined with a strained right rotator cuff, and Wells, out with a strained right forearm, both went on the disabled list April 6.

"I don't think either one is very happy about [leaving the team], and that's OK, too," Cubs manager Mike Quade said Wednesday.

They both had side sessions on Wednesday at Dodger Stadium. The plan is for both to have two more side sessions in Arizona and, if all goes well, face hitters in batting practice.

They're going to Arizona to take advantage of the nice weather.

"If there's ever a place to get a lot of work done rehabbing, Arizona is the place," Quade said. "Hopefully, the next time I see him they'll be on the verge [of returning]."

Quade shows savvy in lineup tweaks

LOS ANGELES -- Mike Quade keeps juggling the lineup, and on Wednesday, his moves paid off.

Jeff Baker made his first start of the season in the outfield in the Cubs' series finale against the Dodgers. It was Baker's first start since Saturday. He's been sidelined with a sore left shoulder.

"I think he'll be fine, and it gives you another option," Quade said. "Like most guys, he wants in so he'll go stand in left and [also] take balls in right."

Baker was batting .480 against left-handers, which is why Quade wanted him in the mix against lefty Ted Lilly. In Wednesday's 5-1 Cubs win, Baker went 1-for-3 with a single in the fifth but was thrown out trying to stretch his hit into a double.

Quade also started Carlos Pena, who hit his first home run Tuesday night. Pena hasn't fared as well, batting .063 against left-handed pitchers.

"We have to get him going, whether it's left-handed, right-handed, whoever we're facing," Quade said. "To have somebody in the lineup, who, on any given pitch [can hit one out], we have to keep the power going."

It worked as Pena hit his second homer of the year leading off the sixth. It was his second hit off lefties this season.

One player who hasn't had as many at-bats is Tyler Colvin. He was batting .132 in 23 games. Last year, he hit .289 in his first 22 games of the season.

"That's probably the toughest thing for me right now," Quade said. "Whether it's spotting Marlon [Byrd] a day or spotting [Alfonso Soriano] a day, it's a very difficult situation for Colvin."

The Reds will start three right-handers in the weekend series at Wrigley Field, and Quade said Colvin could get a start in one of those games. The problem is Soriano, Byrd and Kosuke Fukudome all are playing well, with Soriano leading the Major Leagues with 11 home runs.

"I'd like to play all four of them, and I can't," Quade said.

The Cubs do have off-days Thursday and Monday, which means Starlin Castro will likely keep playing. The 21-year-old shortstop is 1-for-16 in May.

"Any time a guy starts to struggle, you start to think, what adjustments can I make?" Quade said. "I think he's got a short memory and I know he's working like heck to put together good at-bats."

Missouri native DeWitt saddened by flooding

LOS ANGELES -- Cubs infielder Blake DeWitt, who lives in Sikeston, Mo., in the offseason, said he feels for the people near where the Mississippi River levee was demolished.

The demolition has left more than 130,000 acres of Missouri farmland under water.

"We're really close," DeWitt said Wednesday. "We're protected where we're at. It's affecting a lot of people in the area and it's really sad. The river kept rising and it's at historic levels right now. Hopefully, this works out for the best."

However, DeWitt said he's heard the water may not dissipate until the fall. That will be difficult for farmers there.

"It's really sad," DeWitt said. "That's one of the best farmlands in the country."

Friends and family felt the impact of the explosion Monday night.

"They felt the shock waves come through the ground," he said.
