ATLANTA - Dillon Gee's season-long saga took another turn on Sunday when the Mets placed him on waivers, a source confirmed.

The righthander was designated for assignment last Monday, opening a seven-day window for the Mets to explore a trade. But despite some interest, a deal did not materialize.

Teams have until 1 p.m. Tuesday to claim Gee, who is owed roughly $3 million for the rest of the season. If he clears waivers, general manager Sandy Alderson has said he will be sent to Triple-A Las Vegas.

Gee, 29, is 0-3 with a 5.90 ERA in 39 2/3 innings. He started in all but one of his eight games.

If Gee accepts a minor- league assignment, it's unclear whether he'll have a clear path back to the big leagues.

Though the Mets plan to use occasional spot starters to help keep their pitchers within their innings limits, Ward Melville product Steven Matz has made a strong push to get those chances. Matz, 24, is 7-4 with a 2.11 ERA in his first season with Triple-A Las Vegas.

Despite an MLB-wide need for pitching, rival executives seemed skeptical of the Mets' chances of finding a deal. They cited Gee's remaining contract and concerns about his durability. He was sidelined earlier this season with a groin injury and spent two months on the disabled list with a strained lat muscle last season.

An influx of young pitching slowly has pushed Gee into a diminished role since he started on Opening Day in 2013.

With the Mets having a perceived pitching surplus, trade rumors hovered over him throughout the offseason. In spring training, he was moved into the bullpen briefly, though he regained a spot in the starting rotation when Zack Wheeler suffered an injury that required Tommy John surgery.

However, the Mets remained open to trading Gee, whose groin injury opened a rotation spot for Noah Syndergaard.

Gee returned from the DL to make one start in the Mets' six-man rotation before the team shifted gears and ended the experiment, which sent him to the bullpen again.

In his only relief appearance, he allowed a run in 1 2/3 innings on June 8.

Gee made a spot start against the Braves on June 14, allowing eight runs and 11 hits in 3 2/3 innings.
