It turns out Taijuan Walker’s invitation to the All-Star Game may have gotten lost in the mail.

The former Mets pitcher tweeted Wednesday that he was never actually invited to this year’s All-Star Game, denying a report from The Post’s Jon Heyman, who stated Walker had been asked to join the All-Star team as a replacement but already had family plans.

“If there was an opportunity for me to be part of an all-star game I would’ve been there,” wrote Walker, who is now with the Phillies.

“Especially, with it being in the city of the team that drafted me. I was told it was a possibility only! Unfortunately that possibility never fully presented itself. #ThankYou #2ndHalf”

Walker’s response came one day after Heyman’s initial report, which noted, “Taijuan Walker was asked to be on the All-Star team as a replacement, but he already had family plans.”

“Scott Boras, agent for both Walker and Blake Snell, said he was disappointed Snell, a Seattle product, wasn’t then asked to take that spot,” the report continued.

Walker has a 4.02 ERA in 96.1 innings for the Phillies this year, and a 10-3 record —the second-highest win total in the National League.

The 30-year-old pitcher, who was drafted by the Mariners in 2010, was an All-Star during his time with the Mets in 2021.

Walker tossed a 2.66 ERA in the first half of the season to earn the All-Star nod, but crumbled in the second half to a 7.13 ERA, giving up 20 home runs and not winning another game.

The Phillies signed Walker to a four-year, $72 million contract this offseason after he threw 316.1 innings and a 3.98 ERA over two years with the Mets.

Philadelphia is in third place in the NL East and just a half-game out of a wild card spot.

The team has overcome a slow April and May to surge in June and July, over which the Phillies posted a 23-11 record.
