Because of their Yukawa interactions, third generation squarks may be substantially lighter than those of the first two generations. Assuming that {tilde b}{sub 1}{r_arrow}b{tilde Z}{sub 1} and {tilde Z}{sub 1} escapes experimental detection, we show that experiments at the Main Injector upgrade (integrated luminosity of 2thinspfb{sup {minus}1}) of the Fermilab Tevatron should be sensitive to b-squark masses up to 210 GeV for m{sub {tilde Z}{sub 1}}{le}120thinspGeV. For integrated luminosities of 10thinspfb{sup {minus}1} (25thinspfb{sup {minus}1}) the bottom squark mass reach increases by 20 GeV (35 GeV). If the channel {tilde b}{sub 1}{r_arrow}b{tilde Z}{sub 2} is also accessible, the reach becomes model dependent and may be degraded relative to the case where only the decay to {tilde Z}{sub 1} is allowed. In models with gaugino mass unification and {mu} much larger than gaugino masses, we argue that this degradation is unlikely to be larger than 30{endash}40 GeV. {copyright} {ital 1998} {ital The American Physical Society}
