Given the issues in getting timely test results, Jake Diekman has serious questions about Major League Baseball's ability to pull off a season.

The delay in results has forced delays and cancellations of workouts.

The Oakland Athletics left-hander still plans to play, but will be extra cautious. He has the autoimmune condition ulcerative colitis.

"Once the regular season hits, there's no way I'm opting out, but if they don't get the testing figured out, then this whole thing will get shut down," Diekman said. "During the season, there's no way we can go 72 hours or longer without knowing our result. There's just no way. There's no way that can possibly happen and this be safe for all 60, 70 days or whatever it is."
