LOS ANGELES — The Mets attempts to keep Jose Reyes off the disabled list have been proven futile.

The team placed their star shortstop on the DL Thursday, retroactive to July 3. Manager Terry Collins had hoped to keep Reyes available for a series against the Phillies that starts after the All-Star break. Now he will be out until at least the day after that series, July 18.

The All-Star shortstop, who incurred a strained left hamstring running to first base on Saturday against the Yankees, is expected to miss at least two more weeks, testing the Mets’ resolve as they attempt to make a wild-card run.

“It’s disappointing, because I want to be on the field, but it’s part of the game,” Reyes said before the Mets faced the Dodgers on Thursday.

Reyes, who had a second opinion on the hamstring, said there has been no change from the original diagnosis: He’s dealing with a Grade 1 (least severe) strain.

Collins’ preliminary guess is Reyes might return for the Mets’ first road trip after the break, which begins July 22 at Florida.

“It came down to what’s the most important – three games [against the Phillies] or the next 50?” Collins said. “We just thought it was going to be at least another week, if not more.”

Reyes was slated start at shortstop for the NL All-Star team next Tuesday, but will be reduced to watching the game. It marks the third time in his past four All-Star selections that an injury will prevent Reyes from playing in the game.

“It’s a little bit disappointing, because when you go to the All-Star Game, you want to play,” Reyes said.

Nick Evans was called up from Triple-A Buffalo to take Reyes’ roster spot and was in the starting lineup at first base. Ruben Tejada will remain the starter at shortstop, with Justin Turner capable of backing up the position.
