40-something left-handers to duel

Philadelphia (14-19) at Arizona (19-16), 3:40 p.m. ET

Wednesday's series finale will be a matchup for the aged, when lefties Jamie Moyer duels with Randy Johnson.

The contest will be the oldest matchup of left-handed starters in baseball history, at a combined 88 years and 48 days. Moyer and Johnson have a combined 41 years of Major League experience.

This matchup will eclipse the previous high set on April 24, when San Diego's David Wells opposed Johnson. That battle passed Moyer's duel with New York's Tom Glavine on April 12.

The oldest starting pitching matchup ever occurred June 8, 1987, when right-handers Phil Niekro and Don Sutton hooked up. Their combined age was 90 years, 135 days.

Moyer has the edge in this geriatric battle, despite a significant drop in velocity. Moyer began his previous outing against the Giants with six shutout innings, then got into trouble in the seventh when he loaded the bases and surrendered a double to Eliezer Alfonzo. He has faced Arizona only once before, allowing two runs over seven innings and receiving a no-decision.

Johnson is still a work in progress in his first three starts. The Big Unit missed the first few weeks of the season recovering from offseason back surgery. His most recent outing was on Friday against the Mets, and he allowed five runs on nine hits over seven innings.

Pitching matchup
PHI: LHP Jamie Moyer (3-2, 2.85 ERA)
Moyer has gone at least six innings in all six of his starts this season.

ARI: LHP Randy Johnson (0-2, 6.50 ERA)
Johnson is 8-3 with a 2.46 ERA in his career vs. Philadelphia.
