What happened: The Las Vegas Aces announced the signing of Mai Yamamoto in a post from the team's account welcoming her to the roster. Terms of the deal were not disclosed.

Why it matters: The addition continues a busy stretch of roster moves for Las Vegas, which has also signed Ta'Niya Latson and waived Chennedy Carter twice this month while retooling its depth. Las Vegas has been named among the teams that could be active buyers ahead of the WNBA trade deadline.

What to watch: Watch for confirmation of Yamamoto's roster spot and whether she factors into Las Vegas's rotation as the team continues to adjust its depth chart.
