  Employing the heavy quark pole mass and static potential that were obtained
from resummation of the renormalon-caused large order behavior to all orders,
and matching the resummed static potential to the long distance Cornell
potential we obtain a new estimate of the bottom quark mass % $m_b^{\bar{\text
% MS}}=4.20$ GeV at $\alpha_s(M_z)=0.118$ from $\Upsilon$(1S) system. We point
out that the pure perturbative QCD approach to $\Upsilon$(1S) spectrum should
have a sizable systematic error of about 100 MeV, due to the absence of the
long distance confining potential, and that the incorporation of the latter is
essential for accurate determination of the ground state energy. We also
recalculate the nonperturbative Leutwyler-Voloshin effect using a resummed
octet potential matched to a confining linear potential, and obtain a result
that is substantially smaller than the estimates based on Coulombic potentials.
The hyperfine splitting is estimated to be $50 \pm 8$ MeV at
$\alpha_s(M_z)=0.118$.
