These 7 women have all scored big jobs in men’s pro sports leagues

What started with the San Antonio Spurs hiring Becky Hammon in August 2014 has become a movement, whether accidental or intentional. The NBA and NFL beat baseball to the punch, but this week MLB added its own historic first when the Oakland Athletics made Justine Siegal a temporary coach for its Instructional League team.

By the numbers, we’ve seen four female coaches hired in just 14 months, as well as some female “firsts” in non-coaching positions. Here are the 7 women that have grabbed headlines and inspired many with big positions in the last year or so.

Head coach Gregg Popovich (he of our World’s Greatest Leaders list) and the San Antonio Spurs made Becky Hammon one of its assistant coaches just over one year ago. She helped coach the team to the first round of the NBA Playoffs, where the Spurs lost in seven games to the L.A. Clippers. Hammon made history again this summer when the Spurs tapped her to be the head coach of its Summer League team; the Spurs won the league. Read more about Hammon here.

Former college basketball player Sarah Thomas became the NFL’s first female official in April of this year. You can find her on the field this season as a line judge. Back in the preseason, when Thomas found herself officiating a game in which Jen Welter was coaching, the Internet went nuts, and a photograph of the two shaking hands went viral.

Jen Welter (NFL coaching intern)

Dr. Jen Welter, a former football player and coach, got the call-up from Arizona Cardinals coach Bruce Arians in July to be a preseason coaching intern working with outside linebackers. Welter formed tight relationships with many of the players and many were hopeful she’d be kept on as a permanent coach for the regular season. That didn’t happen, but she told Fortune she’s hopeful that her run in the NFL has only just begun. Read more on Welter here.

In July, just days after Welter’s hiring, the Oakland Raiders announced the team had added Beth Mowins to its preseason play-by-play announcing team. Mowins is a broadcast veteran, but had never held such a position—and neither had any other woman apart from Gayle Sierens, who announced one game 30 years ago. When Mowins got in the booth for a Raiders-Chiefs preseason game, she became only the second woman ever to call an NFL game. Read more on Mowins here, at our sister publication Sports Illustrated.

Nancy Lieberman (NBA assistant coach)

Nancy Lieberman, hired as an assistant coach by the Sacramento Kings in August, has such a long history in the sport that it’s surprising it took until now for her to land a permanent job in it. She played for Team USA at the 1976 Summer Games in Montreal and played women’s professional basketball for more than 20 years before there was a WNBA. She’s been inducted into the Naismith Basketball Hall of Fame. And now she’s an assistant coach, the league’s second ever. Read more about Lieberman here.

This former collegiate softball player and All-American is only 34, and made history when she stepped in for Curt Schilling and announced a Sunday Night Baseball broadcast in August of the Chicago Cubs at the L.A. Dodgers. She’ll achieve another first on October 6 when she becomes the first female analyst to call an MLB postseason game for the October 6 American League wild-card matchup.

Justine Siegal already made baseball history back in 2011 when she pitched for multiple different MLB teams at batting practice, including the Athletics, who have now hired her as a coach for this month’s Instructional League. The position may be temporary, but the milestone is a big one. Read more about Siegal here.
