Arizona Diamondbacks general manager Kevin Towers said he is not sure how much longer he will be with the team.

Towers acknowledged that Diamondbacks managing partner Ken Kendrick and president Derrick Hall are disappointed in the team's slow start and that his job may be at stake.

"(Kendrick and Hall) are both very, very disappointed, and rightfully so," Towers told "When you spend $110 million and you're 9-22 at the end of April, I wouldn't be happy, either.

"I'm also disappointed, but I still believe in the core group. I think they will get better. Will I be around to see it? I don't know."

The Diamondbacks (11-23) have the worst record in the National League.
