Henry Wrigley, with an RBI double in the fifth inning, tied a team record for April extra-base hits. He has 14. So did Rhyne Hughes (2009), Elliot Johnson and Michael Coleman (both 2006).
Wrigley has 18 RBIs and has some work to do in that department. Chairon Isenia had 23 in 2005. After that, Reid Brignac had 20 in 2007. Erold Andrus in 2008 and Matt Fields in 2010 each totaled 19 April RBIs.
