Dodgers' Harris stable after bypass

Minor League instructor has surgery to clear blockages

PHOENIX -- Minor League instructor and former Dodgers player Lenny Harris, baseball's all-time pinch-hit leader, is in stable condition at a local hospital after undergoing emergency quadruple heart bypass surgery Saturday, a baseball source confirmed.

Harris was stricken with chest and arm pains Friday, but did not suffer a heart attack as there was no heart damage. In a Saturday operation, doctors found blockages in four arteries, with one 95 percent blocked.

Harris, 45, is in his second season as the senior hitting coach at the Dodgers' Camelback Ranch-Glendale complex, working mostly with Minor League players. Harris returned to the Dodgers after serving the 2008 season as the Major League hitting instructor of the Washington Nationals.

Harris had an 18-year Major League career that included stints with the Reds, Dodgers (1989-93), Mets, Rockies Diamondbacks, Brewers, Cubs and Marlins. He's the all-time pinch-hit leader with 212.
