      Re:  Registration Statement on Form S-3
           ----------------------------------
Ladies and Gentlemen:

      We have acted as counsel to SportsLine.com, Inc., a Delaware corporation
(the "Company"), and have reviewed the Company's Registration Statement on Form
S-3 to be filed on or about June 19, 2000 (the "Registration Statement") in
connection with the registration under the Securities Act of 1933, as amended,
of a total of 392,095 shares (the "Shares") of the Company's Common Stock to be
sold by certain shareholders listed in the Registration Statement (the "Selling
Shareholders").

      It is our opinion that the Shares, when sold by the Selling Shareholders
in the manner referred to in the Registration Statement under the caption "Plan
of Distribution," will be validly issued, fully paid and non-assessable.

      We hereby consent to the use of this opinion in the above referenced
Registration Statement. In giving such consent, we do not hereby admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission promulgated thereunder.

                                                  Very truly yours,

                                                  /S/ Greenberg Traurig, P.A.
