can pitchers tire throughout the season?

Can pitchers tire over the course of a season? I am getting a lot of use out of my bullpen. They are doing great, but I'm just wondering if that will hurt me later in the year. Thanks! :?

No. RPers are tired if they pitch in 3 straight games but otherwise there is no such thing as being tired for overuse.
