A’s officials aim to narrow their list of sites for a potential new stadium in the Las Vegas area to a few finalists by early November, soon after baseball’s postseason ends, team president Dave Kaval said Friday.

Team officials made another trip to the Las Vegas area this week, their sixth since MLB gave permission for the A’s to explore relocation while also pursuing a new ballpark in Oakland. Kaval said the trip included meetings with Clark County commissioners, local unions and the Mayor of Henderson, Debra March.

The A’s have looked at up to 20 sites that could potentially house a major-league ballpark in Southern Nevada, including near the resort corridor and in locales like Henderson and Summerlin, Kaval has said.
