Quad strain sends Mets' Murphy to DL

PHOENIX -- The Mets placed infielder Daniel Murphy on the 15-day disabled list Friday with a left quad strain, recalling Danny Muno from Triple-A Las Vegas to replace him. Murphy, 30, strained his quad running out a routine ground ball in Thursday's win over the D-backs. The Mets offered no timetable for his return -- only assurances that it's not a serious strain.

"It's not real serious," manager Terry Collins said. "But David [Wright's] hamstring wasn't very serious, either."

Murphy will remain with the Mets until next week, when he will travel to Florida to begin his rehab. He was by far the club's hottest hitter in the weeks leading up to his injury, batting .346 with 11 doubles and three home runs in his last 37 games.

"It's frustrating because I'm not going to be able to be with these guys for a little bit," Murphy said. "But the news could have been worse. There are definitely worse things that have happened on earth than me going to the DL."

With Murphy sidelined, Collins said Ruben Tejada will remain at second base on a full-time basis, but third base will become a "day-to-day" decision. At this point, any production at all from the hot corner could result in a string of playing time for either Campbell, who entered Friday's play in an 0-for-27 slump, or Muno, who was hitless in his last 14 at-bats over two stints at the big league level.

The Mets optioned Muno to Triple-A earlier this week, but were allowed to recall him before the typical 10-day waiting period due to Murphy's DL assignment.

"They were pretty limited," Collins said of his third-base options. "This was what we thought was the best way. We'll see how this goes."
