The frequency of a cavity-stabilized laser is locked to the saturated fluorescence in a thermal Sr atomic beam and is measured with an optical-frequency comb-generator referenced to the SI second through a GPS signal. The $^88$Sr transition is measured to be at 434 829 121 311 (10) kHz. We measure also the $^88$Sr-$^86$Sr isotope shift to be 163 817.4 (0.2) kHz.
