Who is that FSN intern?

When Sara Mosiman’s basketball playing career ends, she plans to keep working in sports. That’s why she was at Safeco Field Tuesday.

Mosiman, best known as a guard on the University of Washington women’s basketball team, was at the Mariners ballpark enjoying her second day as an intern for FSN. The former King’s High School multi-sport star is slated to work about 28 hours per week for the TV station. She is majoring in communications at the UW, where she will be a senior when classes begin this fall.

“I’ve known I’ve wanted to be involved in sports the rest of my life,” Mosiman said, standing at the top step of the Mariners dugout during batting practice, “so this just seems like the most logical way to go about it, because I’d probably be doing research and going on to ESPN.com anyways.”

Mosiman started her FSN gig after completing a five-month internship with KJR sports radio. She helped with Elise Woodward’s show.

“I’m just kind of testing everything out, seeing what I like,” said Mosiman. “I really like the broadcast thing. I was a big fan of radio so we’ll see what TV has to offer.”

As for basketball, Mosiman said she’s excited for the upcoming season, her final one as a Husky.

“Finally, we have some veterans,” she said. “We’ve been a young team for basically like four years so it’s kind of a year we’re getting more experience and I think that’s what’s going to help us a lot.”

Johnson should return today

Seattle catcher Rob Johnson (sore throwing elbow) has missed the past three games but will return to the lineup today against the White Sox, manager Don Wakamatsu said. Kenji Johjima caught in place of Johnson. “He had some tenderness in it (Monday) and I told him I’d give him one more day,” Wakamatsu said.

Fister’s big debut

Before pitcher Doug Fister made his first major-league start Tuesday, he got lots of encouragement. “We had a long talk the other day, just trying to give him some words of advice and trying to relax him,” Wakamatsu said. “Let him know that everybody goes through it and you’re not alone out there.”

Mariners outfielder Michael Saunders, who made his major-league debut July 25, understands the mix of excitement and nervousness Fister was likely feeling.

“I think everyone’s done a great job making him feel comfortable, just like they did with me a couple weeks ago when I first got called up,” Saunders said. “We’ve got a great clubhouse and a great group of guys trying to take care of the younger guys when they get called up.”

All or nothing

Lately, when Russell Branyan is at the plate it’s either a home run or a strikeout. Going into Tuesday’s game, Seattle’s Branyan had three hits, all homers, in the previous five games. During that stretch, he was 3-for-22 (.136) with seven strikeouts. For the season, Branyan’s 27 homers accounted for nearly 29 percent of his hits.
