Cree Summer (Backyard Sports: Baseball 2015, possibly)
Her voice was heard in Backyard Sports: Baseball 2015, but not herself. This also happens to Vinnie The Gooch.
Sunny Day has dark brownish-red hair. She wears a blueish-purple jacket over a yellow long-sleeved t-shirt and wears red lipstick. In the old games, her hair is almost in bangs and wears it in a bun. But in later games like Backyard Football 2004 or Baseball 2005, she has bangs and her hair is worn in a mullet.
Unlike professional play-by-play announcers (with the exception of regional announcers), Sunny Day will commentate a bias for the human player. In the spectator mode for Backyard Hockey 2005, this bias is given to the 'Away' team curiously.
