Nava became just the second player in franchise history to homer in his first two plate appearances in his first game with the Phillies. Jeremy Giambi homered in his first two plate appearances against the Expos at Olympic Stadium on May 25, 2002. Gene Freese homered in his first two plate appearances with the Phillies in 1959, but they came in two games five days apart.

Interestingly, Nava hit a grand slam against Phillies right-hander Joe Blanton in his first big league plate appearance with the Red Sox on June 12, 2010.

Nava started in left field on Thursday, as Phillies manager Pete Mackanin wanted to give some of his bench players the opportunity to play after not having played since Friday’s Grapefruit League finale in Clearwater, Fla.

The power display from a Phillies left fielder is welcome. Phillies left fielders hit just 13 home runs last season. They did not hit their second homer until May 18.
