Puig aggravates hamstring in rehab game

DENVER -- Dodgers outfielder Yasiel Puig, on the disabled list, reinjured his strained left hamstring running to first base in a Minor League rehab appearance Friday night, the Dodgers confirmed.

Puig, who homered earlier in the game in Adelanto, Calif., left after 4 1/2 innings. He is heading back to Los Angeles to re-evaluated. ThinkBlueLA reported that Puig said he felt his hamstring tighten a little when the temperatures cooled.

Puig, who served as designated hitter Thursday, was expected to play Friday and Saturday games and be activated Monday. He is eligible to be activated Sunday, but manager Don Mattingly said the plan was to wait until the team returned for the homestand that opens Monday night.

Puig has played only 11 of the Dodgers' 29 games.

Additional rehab notes:

• Mattingly said Hyun-Jin Ryu still hasn't resumed throwing after a setback in his recovery from a left shoulder impingement.

• Carl Crawford has not resumed baseball activities after straining an oblique.

• Joel Peralta is improving but hasn't resumed throwing after being disabled by a pinched nerve in his neck.

• Brandon League continues in bullpen sessions as he rebuilds arm strength after a right shoulder impingement.
