With David Wright's return from his hamstring injury delayed and the Mets beginning to teeter, Sandy Alderson made the aggressive move late Thursday night to shift Daniel Murphy to third base and call up Dilson Herrera, 21, to play second.
Herrera, who was batting .370 in Triple-A, went 0-for-3 in Friday night's 4-0 victory over the Nationals at Citi Field. Alderson said this will be the configuration until Wright returns from his hamstring strain. The Mets had hoped he would come back this weekend. Then they targeted next weekend, and now that timetable also might be pushed back.
"Dilson's been playing very well at Las Vegas," Alderson said. "Second, we realized David wasn't coming back as early as he might have hoped and we might have hoped. Thirdly, we wanted to change things up a little bit."
Alderson said Wright has backed off doing any baseball activity and is working on getting the hamstring healed.
Herrera hit .220 with three homers and 11 RBIs in 18 games with the Mets in 2014.
Believing in Flores
Alderson expressed support for shortstop Wilmer Flores, who committed his sixth error Thursday. "We know he can catch the ball," Alderson said. "The important thing right now is to make sure he knows we have confidence in his ability to catch the ball. He's demonstrated it. This is not a hope and a prayer." Flores caught the ball just fine Friday night but had a throwing error for No. 7.
Steven Matz (Ward Melville) struck out a career-high 12 Thursday night for Las Vegas. Matz (3-1, 1.84 ERA) allowed one run, five hits and two walks in seven innings in a 7-2 win over Reno.
