One day after laughing off the notion of giving struggling ace Matt Harvey an extra rest day before his next start, Mets manager Terry Collins did exactly that Friday when he added spot starter Dillon Gee to the rotation.

Gee (0-3, 4.50 ERA) will start Sunday, less than a week after he lost his spot when the Mets hastily ended their short-lived experiment with a six-man rotation.

"We think they need an extra day right now," Collins said of the rotation.

Gee last started June 3. His lone relief appearance came Tuesday, when he allowed a homer.

Collins insisted that the Mets are not returning to a six-man rotation but merely staying in a five-man rotation and occasionally using a spot starter. "It became such an animal, such a big monster, that I said I'm not going to deal with this," Collins said. "I'm not going to answer these questions every day."

Harvey, Jacob deGrom and Noah Syndergaard face innings limits. The Mets want to manage their workloads and avoid in-season shutdown periods, prompting constant juggling that has worn on Collins. "Nobody liked it," he said.

Goeddel to DL

The Mets sent reliever Erik Goeddel to the disabled list with a strained right elbow. He was replaced on the roster by switch-hitting infielder Danny Muno. Goeddel, 26, had helped to solidify a banged-up bullpen, posting a 1.96 ERA in 23 innings during the first significant big-league experience of his career.

Extra bases

Slumping Lucas Duda was held out of the lineup against Braves lefthander Alex Wood . . . The Mets' annual Banner Day competition will be Sunday before the series finale against the Braves.
