An advance scout provides the scouting reports the players and coaches use prior to each series during the season.
General manager Jack Zduriencik said the Mariners might not use one this season.
"We haven't made that determination yet," Zduriencik said Tuesday. "One of the things we may do is [get the information] via video. We did that in Milwaukee and it was very effective.
"We set up a really good video team to do a lot of the advance work."
Zduriencik said he has discussed the situation with manager Don Wakamatsu.
"I think most managers are comfortable with having a guy in the ballpark, but you also can sit back and see a lot of things on video that you might miss during the course of a game," Zduriencik said.
"They both work hand in hand and should this ballclub become [a playoff contender], we can have some of our people doing some advance work [on the road]."
