Tampa Bay Rays. So far in the 2023 MLB season, they’re standing alone (like Godsmack) as MLB’s only undefeated team in the season, with a 9-0 record. While undefeated starts in the sports world are common, the way the Rays have been doing it hasn’t been seen since the 1884 St. Louis Maroons started that season 13-0. The Rays have won all 9 games by 4 or more runs (the most dominant being a 11-0 victory against the visiting Oakland Athletics on April 9th)
