SEATTLE — The Seattle Mariners signed general manager Jerry Dipoto to a multiyear contract extension on Friday, a reward for the club being on track to end the longest playoff drought in the four major professional sports in the U.S.

The agreement comes with the Mariners 24 games above .500, and striving to make the postseason for the first time since 2001.

“Jerry arrived here 2½ years ago with a specific plan for our franchise,” Seattle president and CEO Kevin Mather said. “He has successfully executed that plan, resulting in a younger, more athletic and, most importantly, far more successful major league team.”

Dipoto is in his third full season with the Mariners, who are 56-32 and 1½ games out of first place in the AL West. Since the start of the 2016 season, his first full year, the Mariners have the eighth-best record in the majors at 220-192.

“As I said when I arrived here, I believe this organization has every opportunity to be successful on a consistent basis,” Dipoto said in a statement.

While there are still issues in the farm system, Dipoto has succeeded in making the major league product better. He’s turned over a roster that had gotten old and added key younger pieces like Mitch Haniger, Jean Segura and Dee Gordon, who are all major contributors in Seattle’s start to this season. The trade that landed Haniger and Segura from Arizona before the 2016 season now looks like a coup pulled off by Dipoto.

Dipoto also has locked up key parts of Seattle’s core for the next several seasons, either by having club control through arbitration or by signing long-term extensions. All of Seattle’s current starting rotation is under contract through the 2019 season and the only everyday player without club control beyond this season is designated hitter Nelson Cruz.

Dipoto arrived in Seattle in 2015 charged with finding stability after the final years under Jack Zduriencik had crumbled.
