We report on the attainment of a spin-polarized Fermi sea of (87)Sr in thermal contact with a Bose-Einstein condensate (BEC) of (84)Sr. Interisotope collisions thermalize the fermions with the bosons during evaporative cooling. A degeneracy with T/T(F) = 0.30(5) is reached for a (87)Sr Fermi sea of 2 x 10(4) atoms together with an almost pure (84)Sr BEC of 10(5) atoms.
