Dodgers contemplate move upon return to LA

TORONTO -- With Matt Kemp going on the disabled list on Wednesday and Ted Lilly activated from it, the Dodgers figure to make a follow-up move for a position player as soon as Thursday, when they return to National League rules against Cincinnati at Dodger Stadium.

While an outfielder will be needed, it can't be Scott Van Slyke, who was optioned on Sunday and is not eligible to return until July 31, unless he replaces an injured player.

Alex Castellanos, who spent a week with the Dodgers when Van Slyke was injured, would be a logical candidate.

The Dodgers would need to counter the addition of a position player with the subtraction of a pitcher. The most obvious choice would be Chris Withrow, who has options and can be sent to the Minors without risk of being lost to another club.

Lilly to work out of bullpen after activation from DL

TORONTO -- Ted Lilly is back, this time as a reliever.

Lilly was activated from the 15-day disabled list Wednesday when Matt Kemp was added. Lilly will try his left hand at relieving after a career as a starter.

Lilly accepted the role change because his most recent injury, a flare-up of degenerative arthritis in his neck, had worsened to the point where he couldn't handle the physical demands of starting.

Manager Don Mattingly said Lilly could be used in several situations, from getting a left-handed hitter or in a long role. The Dodgers have not had a true long reliever this year.

"He will allow me to use [Chris] Withrow a little differently," Mattingly said.

Lilly last pitched in a Major League game on June 4. He was disabled earlier this season with a strained ribcage muscle and the lingering effects of last year's shoulder surgery.

The 37-year-old has gone 0-2 with a 5.09 ERA in five starts with the Dodgers this season.

Belisario's turnaround matches team

TORONTO -- As Ronald Belisario goes, so go the Dodgers?

When the Dodgers hit bottom June 22, falling 9 1/2 games out and in last place in the National League West, Belisario had an ERA of 4.64. While the club has made its run from worst to first, Belisario hasn't allowed an earned run over his last 13 appearances, his ERA down to 3.40.

He's struck out 13 in 13 innings with three walks and seven hits, while earning back the set-up job.

"When we've got guys in the middle of the order to go through, like [Jose] Bautista and [Edwin] Encarnacion, it's a good feeling having Beli out there," said manager Don Mattingly. "If he's going good, he's got that inning."

Mattingly said the difference in Belisario when he's good from when he's not is the movement of his pitches.

"All spring it was sideways," Mattingly said. "But Rick [Honeycutt, pitching coach] kept working with him. The velocity was always there, he was throwing hard but it was just sideways. Now it goes down and that's the difference. He threw two balls [Tuesday] night to Bautista that were just filthy."
