Joseph Estes: Everything you need to know

The Athletics optioned Estes to Triple-A Las Vegas on Wednesday. After overcoming a herniated disc in his lower back, Estes threw 2.2 scoreless innings in Tuesday's Cactus League game against the White Sox in his spring training debut. He now finds himself cut from big-league camp a day later. Estes is ticketed for the Triple-A Las Vegas rotation at the start of the season.

Estes (back) is scheduled to make his spring debut during Tuesday's Cactus League game against the White Sox, Jason Burke of SI.com reports. The right-hander finished last season on the injured list due to a herniated disc in his lower back, and he ramped up slowly early on in spring training. Estes made just three appearances for the A's last season and spent most of the campaign at Triple-A Las Vegas, where he struggled to a 5.51 ERA across 80 innings.

The Athletics placed Estes on the 15-day injured list Wednesday, retroactive to Monday, with a herniated disc in his lower back. Estes performed well Sunday during his return to the majors, firing four shutout innings while allowing one hit and striking out one batter. He'll now be forced to sit out until at least Sept. 9, however, and the A's will call up Brady Basso from Triple-A to fill the opening on the active roster.
