Caitlin Clark's WNBA debut finally arrived on Tuesday, but it didn't go as planned ... she logged 10 turnovers -- and her Fever team lost by double digits.
The former Iowa superstar's W career officially kicked off in Connecticut ... as she and Indiana took on the Sun for their season opener -- and initially, things went well.
The arena was packed -- and she was cheered at player introductions ... despite it being an away game.
But, after tip-off, it wasn't all roses for the sharpshooter ... her 10 TOs ended up being the most in Fever history -- and her squad ultimately fell 92-71.
