Delayed before the start, the game was finally called after a wait of an hour and 32 minutes due to rain, and it was rescheduled as the day portion of a day-night doubleheader Wednesday.
Carlos Martinez (8-6, 2.85 ERA) is expected to work the opener for St. Louis against Colin Rea (5-3, 4.95). In the nightcap, the Cardinals will pitch left-hander Jaime Garcia (6-6, 4.11) against Paul Clemens (1-0, 4.73).
The Cardinals (48-44) opted not to start the game as planned Tuesday when the storm was detected less than 30 minutes before the scheduled first pitch. Neither Martinez or Rea even started his warmups, and the field was covered shortly after the national anthem.
The first raindrop didn't fall until around 8:45 p.m. CDT, but before it did, the fans scurried for cover as they were encouraged to leave the seating area. The storm featured frequent claps of thunder, lightning and sheets of rain blowing from left to right.
With this being San Diego's only trip into St. Louis this year, a day-night doubleheader was the only option to make it up. The teams have no mutual off days for the season's remainder, and they already played their series in San Diego.
Martinez will be pitching on 11 days of rest, his last outing coming on July 9 in an 8-1 win at Milwaukee that saw him match a career high by fanning 11 in five innings. He is 0-1 with a 5.51 ERA in five career games against the Padres, two of them starts.
Rea will be facing the Cardinals for the third time in his short major league career, but the first time in St. Louis. Rea absorbed a 10-3 loss to them last August and got a no-decision on April 24 in an 8-5 loss. He hasn't pitched since a no-decision July 6 in Arizona, when he was hooked one out shy of a win in San Diego's 13-6 victory.
In the nightcap, Garcia will make his first start against the Padres since Sept. 10, 2012, when he ate an 11-3 loss. He wasn't involved in the decision Friday night in a 7-6 loss against the Miami Marlins, pitching 6 1/3 innings and allowing four runs.
Clemens will replace Wednesday night's scheduled starter, Andrew Cashner, who will be pushed back to Thursday night's series finale. Clemens, who was picked up off waivers from Miami on June 28, has no record and no ERA in three relief appearances with San Diego.
NOTES: St. Louis 3B Jhonny Peralta went on the 15-day DL Tuesday, retroactive to Monday, due to a strained ligament in his left thumb. Peralta left Sunday's game in the fifth inning after injuring himself while hitting. He was replaced on the roster by OF Jeremy Hazelbaker, who was recalled from Triple-A Memphis. ... RF Matt Kemp's homer in the fourth inning Monday night gave San Diego 108 for the season, keeping the Padres well ahead of pace to break the franchise record of 172, set in 1970. ... In other roster moves, the Cardinals recalled RHP Miguel Socolovich from Triple-A Memphis while designating C Michael McKenry for assignment.
