The Oakland Athletics have hired Justine Siegal as a guest instructor for the team's 2015 instructional league.

Siegal will work with players Oct. 4-17 at the Lew Wolff Training Complex in Mesa, Ariz. She was the first woman to throw batting practice for a Major League team a few years ago.

"This was a great moment," Siegal said. "I feel qualified for this job. I have a lot to learn, but I feel I've worked my way up the ranks. I can't stress enough how thankful I am for the opportunity."

The Athletics are the first Major League team to hire a female coach. In 2009, Siegal also became the first woman to be hired as a coach at any professional level, when she served as first-base coach for the Brockton Rox, an independent baseball team.
