Arturo Moreno
Angels fans thought it was good news when Moreno bought the franchise in 2003. He became the first Latino MLB owner in history and appeared to be a baseball fan too. But it all went downhill from there because he ran the team into the ground. Moreno ignored scouts and paid massive contracts for underperforming athletes.

Then the team found itself with two of the most exciting players in MLB. We’re talking about Shohei Ohtani and Mike Trout but Moreno refused to surround them with talent. Trout only made a single postseason foray in his career and this is scandalous. He’s one of the worst owners ever (via L.A. Times).
