Odalis Perez left his most recent start with a tight left shoulder.
Perez was forced to leave after five innings Thursday in the Dodgers’ 8-4 win over Diamondbacks. He allowed three runs and five hits, but did not get the decision.
The 27-year-old left-hander spent three weeks on the disabled list earlier this season with inflammation in his rotator cuff.
“It’s in the same place and it feels the same, no pain, but tightness,” Perez said. “I didn’t feel comfortable warming up, then it got better in the game, then it got worse in the fourth and fifth innings.”
Perez, who has not earned a decision in any of his past four starts, will now look to lead the Dodgers to just their third win in seven games.
After getting swept in a three-game weekend series against the St. Louis Cardinals, Los Angeles opened the set with an 8-2 win on Tuesday.
Hideo Nomo won for the first time in 11 decisions, and pinch-hitter Robin Ventura hit his 18th career grand slam to tie Willie McCovey for third place on the career list. Hall of Famers Lou Gehrig (23) and Eddie Murray (19) are the only players with more.
With the win, Los Angeles extended its lead over San Francisco to 4 1/2 games in the NL West.
The loss put the Diamondbacks a club-record 54 games under .500. Arizona’s next defeat will tie the club record for losses, set in 1998, when the Diamondbacks finished their inaugural season 65-97.
Casey Fossum will try to help the Diamondbacks delay that ignominious achievement.
Fossum has won his last two decisions after dropping his previous six. The 26-year-old left-hander allowed three runs and four hits over seven innings Thursday, but he did not get a decision in the Diamondbacks’ 8-4 loss to the Dodgers.
“He threw the ball real good,” Arizona manager Al Pedrique said. “We keep wasting these quality starts. That’s either eight or nine in a row.”
