Matt Kemp starts rehab assignment

Los Angeles Dodgers outfielder Matt Kemp began his rehab assignment Tuesday with a two-hit performance at Class A Rancho Cucamonga.

Serving as the Quakes' designated hitter, Kemp singled to left field in his first at-bat Tuesday and scored from third base later in the first inning. The two-time All-Star walked in the second inning and struck out in the fourth before capping his night with a line-drive single to right field in the seventh.

Kemp had been sidelined since May 30, when he aggravated his left hamstring and returned to the disabled list. He plans to participate in Monday's All-Star Home Run Derby and is expected to return to the Dodgers' lineup July 13 against San Diego.

Despite playing in just 36 games this season, Kemp leads the Dodgers with a .355 batting average and 12 home runs. His return should bolster a Los Angeles team that has lost 12 of its past 15 contests and has averaged just 1.9 runs per game over that span.

Dodgers second baseman Mark Ellis and reliever Javy Guerra also appeared in Tuesday's game as part of their respective rehab assignments.

Ellis, who could be activated from the DL as early as Wednesday, had a pair of singles and scored a run for the Quakes. Guerra tossed a scoreless inning as Rancho Cucamonga's starter.
