meaning of "triumph over experience"

[Learning_English]

The man against whom perhaps they have the greatest question is of course Virender Sehwag. He hasn't scored a century since April 2005. In the last 15 innings he played he has made only 180 and his record over that in fact is an average of just 17.30. Many people say that in picking Sehwag you have allowed hope to triumph over experience.

Please explain the meaning of `triumph over experience' in the above paragraph

Experience (the past) demonstrates that Sehwag has a poor record; choosing him anyway is evidence that one hopes for more than experience shows: ergo, hope triumphs over experience.

The experience referred to is the bad part. The text says nothing about prior to 2005.
