In 2010, the San Diego Padres traded for Ryan Ludwick at the trading deadline. They were a game-and-a-half up in the division, and Ludwick was hitting .281/.343/.484 for the Cardinals. After the trade, Ludwick hit .211/.301/.330, and the Padres went 30-30, losing the division by two games.
In a way, Ludwick was partially responsible for the Giants winning the West, which would put them in line for their first World Series title in San Francisco.
So he's making up for lost time. If the Reds hang on to their series lead and advance to the NLCS, Ludwick will likely get some consideration for the series MVP. Actually, I don't think they have division-series MVPs. But they should. And Ludwick would have a shot because he keeps doing stuff like this:
After the third-inning homer, Zito allowed a two-out walk, and that was it for him. Giants manager Bruce Bochy pulled Zito, who allowed eight runners, and brought in reliever George Kontos, who got a fly ball to end the inning.
