J.A. Happ looks to remain with the Toronto Blue Jays for the rest of the season.

The Blue Jays pulled Happ back from revocable trade waivers after an unknown team placed a claim on the 34-year-old starter, reports Jon Heyman of FanRag Sports.

It's unknown which team made the claim and it's unclear if it was placed with an intent to strike a deal for the pitcher or to simply block a potential move to another club.

Happ has posted serviceable numbers with the Blue Jays in 2017. The left-hander owns a 4.10 ERA in 107 2/3 innings this season and is also striking out nine batters per nine innings.

Any club hoping to add reinforcements for a postseason run will need to strike deals before the end of August, as players added to the roster in September are not eligible to play in the postseason.

Teams have 48 hours to negotiate a deal after a waiver claim is made.
