His ERA ballooned by almost three runs the next year, and the Astros traded him along with Jeff Juden to the Philadelphia Phillies in exchange for Mitch Williams in December 1993. Jones redeemed himself in 1994, recording 27 saves with a 2.17 ERA, and the win at the All-Star Game, his fifth appearance at the Midsummer Classic. At the end of the season, Philadelphia opted not to sign him to a multi-year contract, and Jones left as a free agent.
