ST. LOUIS -- The San Diego Padres juggled their rotation after Tuesday night's game against the St. Louis Cardinals was postponed because of anticipated storms that finally materialized about one hour and 45 minutes after the scheduled start.

Busch Stadium was dry but empty when heavy rains began.

The Tuesday night pitching matchup, Colin Rea vs. Carlos Martinez, moves to the Wednesday opener at 2:15 p.m. ET. Paul Clemens gets a spot start in the second game set for 8:15 p.m. ET and will oppose Jaime Garcia.

Andrew Cashner gets bumped back a day to the series finale on Thursday, opposing Adam Wainwright.

Clemens (1-0, 4.73) made two starts for Miami, the most recent one on June 25, three days before being claimed by the Padres. In 14 starts for Triple-A New Orleans he's 6-4 with a 4.30 ERA.

Both clubhouses were closed after the postponement was announced.
