Scott Rolen
The Cardinals opened 2010 on April 5, on the road at Cincinnati. St. Louis won 11–6 on six effective innings from Chris Carpenter. Albert Pujols had two home runs. Colby Rasmus had a home run, and robbed Scott Rolen of a home run. Yadier Molina hit a grand slam home run, and became only the third Cardinals ever to do so on opening day. The other two Cardinals to ever do so, Mark McGwire and Scott Rolen, were also in attendance. In the home opener on April 12, St. Louis beat Houston 5-0 behind a three-run home run from Pujols and eight shutout innings from Adam Wainwright.
