When Emma Tiedemann takes the NESN mic Tuesday night to call the Boston Red Sox game against the Kansas City Royals at Fenway Park, it will be her second big league game. Already having the experience doesn’t mean her nerves won’t be in overdrive before the first pitch.

“The million butterflies are still here. They have never left,” Tiedemann said.

The play-by-play voice of the Portland Sea Dogs, the Double-A affiliate of the Red Sox, Tiedemann will be on the call of Tuesday’s Red Sox game as a part of the Women’s Celebration Night at Fenway Park, which will feature an all-female broadcast team. Joining Tiedemann in the booth to call the entire game will be NESN’s Alanna Rizzo on color commentary. NESN reporter Kasey Hudson will handle sideline reporting duties. The pre- and postgame studio show will be anchored by Natalie Noury, NESN’s Worcester Red Sox and Hockey East reporter. Jen McCaffrey of The Athletic will serve as the studio analyst.

Last season, Tiedemann and her then-partner with the Sea Dogs, Rylee Pay, did a few innings of a Red Sox game against the Toronto Blue Jays at Fenway on Aug. 26, taking the reins from Dave O’Brien and Kevin Youkilis in the fourth inning through the remainder of the game. In 2023, Tiedemann and Pay, who now calls games for the Tacoma Rainiers, the Triple-A affiliate of the Seattle Mariners, became just the second all-female broadcast team in professional baseball.

A seven-time Emmy winning reporter, Rizzo joined NESN this spring, and co-hosts “Unobstructed Views,” NESN’s alternate broadcast of Red Sox games found on NESN+. Tuesday’s game will be Rizzo’s first time as a color analyst. She said she and Tiedemann planned to watch Monday’s game together at Fenway Park and get to know each other a little bit.

“I’m not really sure what to expect. I will be as prepared as I possibly can (be),” Rizzo said. “The biggest thing is making sure that Emma takes the lead. She’s the play-by-play voice, and I’m just there to add some value in terms of story telling and some color. I’m not going to be Lou Merloni. I’m not going to be Will Middlebrooks. That’s not who I am. I won’t be breaking down pitch sequences and those type of things. I’ve covered the game for decades, but never in this role. … Emma knows what she’s doing. She’s been doing play-by-play for a long time. I have no hesitation at all that she’s going to do an amazing job.”

Tiedemann said the biggest difference between calling a Sea Dogs game and the Red Sox is the amount of information she’ll have at her disposal on NESN’s broadcast.

“To give you an idea, our TV production in Portland has two people. We have a director and we have a replay person. We don’t really have graphics that I can call for because in my ear is actually our radio producer, because we simulcast on the radio,” she said. “Just having the access to the different angles of everything, not to mention the stats. I’ll never forget last season, having somebody in my ear just giving me stats, and I had no idea how they could do it so quickly. But here they are and they’re right at my fingertips.”

Having that experience last season will allow Tiedemann to look at the monitor more as she calls the game, knowing all the support she has behind the scenes from the production crew. She’ll lean more into the TV style of a broadcast, rather than the radio style she’s used to calling with the Sea Dogs.

Rizzo was part of the first all-female baseball broadcast in 2021, when she served as sideline reporter for a game between the Tampa Bay Rays and Baltimore Orioles produced by the MLB Network and YouTube. For that game, Melanie Newman handled play-by-play, with Sarah Langs the color analyst. The studio show featured Heidi Watney and Lauren Gardner. Rizzo said doing color commentary Tuesday will be a fun new experience, but she doesn’t expect it to result in a new career path.

“I love sideline reporting, the story telling element of the job,” she said.

For Tiedemann, who first caught the play-by-play bug calling games in the Alaska Baseball League, a summer collegiate league, in 2014, Tuesday’s Red Sox game is a step towards her ultimate career goal of working as a major league broadcaster.

“I’ve been really happy with my career so far. I am moving up, slowly but surely, but that’s also the industry. That is my overall goal, to be full-time with a (major league) team at some point,” Tiedemann said. “I’m not rushing things. I’m taking it one day at a time, one game at a time. I’m happy with where I’m at for right now. I’m happy with how things have gone so far.”

Rizzo said she looks forward to the day an all-female broadcast team isn’t outside the norm.

“It would be great if gender wasn’t even an issue. We’re having this conversation right now and doing these interviews because it’s an all-female broadcast, but if you look at the resumés, I mean, we’ve been doing this for decades,” Rizzo said. “While it is unique because of our gender, the second the first pitch is thrown and Emma calls the first pitch, we’re off and running.”
