• The Pirates added a new wrinkle into the race for the National League Central title by acquiring Twins first baseman Justin Morneau on Saturday afternoon. Morneau was expected to arrive at PNC Park during Saturday's game.
• Though Jake Westbrook's bullpen session went well Friday, the Cardinals remain coy with what the next step is in the right-hander's rehab program. Westbrook, who was placed on the disabled list due to a lower back strain, is eligible to come off the DL on Friday.
• The Cardinals need to win all five of their remaining games against the Pirates to finish with a winning record in the season series. That head-to-head record could have implications in certain postseason tiebreak scenarios.
