Steven Matz has done little wrong in his first season with the New York Mets but sleeping has suddenly posed a problem.

The Mets have moved Matz' scheduled start back one day, and they'll instead turn to Logan Verrett against the Philadelphia Phillies on Wednesday night.

Matz has been terrific through six starts this year, going 4-0 with a 2.27 ERA - 2-0 with a 2.86 ERA in four since missing nearly two months with a partially torn lat muscle.

Now, he's dealing with discomfort in his back after spending a night on a couch.

"It's just kind of one of those things where you wake up and I slept wrong or something," Matz told MLB's official website. "It's definitely making improvement."

The Mets (89-68), however, aren't taking any chances since Matz is supposed to join Matt Harvey, Jacob deGrom and Noah Syndergaard in their postseason rotation. That's reason enough to move his scheduled start back to Thursday's finale of this three-game set and advance Verrett forward one day.

Verrett (1-1, 2.70 ERA) is 1-1 with a 3.00 ERA in three spot starts this year after allowing two homers and four runs in a 6-2 loss to Atlanta on Sept. 22. The rookie right-hander's other 13 appearances have come in relief, including a perfect seventh inning of a 9-5, 13-inning win at Philadelphia on Aug. 27.

He was originally scheduled to make this start in place of Jonathon Niese, who was moved to the bullpen in preparation of the playoffs.

New York had its franchise-record 11-game road winning streak end with Tuesday's 4-3 defeat at Philadelphia (60-97). However, Lucas Duda remained hot and went 3 for 5 with two homers and three RBIs.

The first baseman has homered five times on six hits in 12 at-bats while driving in 13 runs over the past three games. Duda is 9 for 17 in the past five contests after batting .154 with one homer and two RBIs over the previous 13 following a stint on the disabled list due to a back strain.

"He's getting hot at the right time," manager Terry Collins said.

Duda is 10 for 20 with five homers and seven RBIs in his last five meetings with Philadelphia.

Alec Asher (0-5, 7.52) will try to slow him down and avoid becoming the first Phillies pitcher to begin his career losing six straight starts since Frank Hoerst did it in 1941.

"You want to finish strong," Asher told MLB's official website. "That's the main goal. I know I've started 0-5. I don't want to start my career like that, but there's nothing I can do about those past games."

The rookie right-hander is also attempting to prove he's worthy of a spot in next year's rotation. He showed some promise Thursday, yielding one run and three hits in seven innings of a 1-0 loss at Miami.

"With each start, I'm building more confidence," said Asher, who lowered his ERA more than two runs.
