New Met Jed Lowrie hit the first MLB homer in Citi Field history -- and it was a grand slam

The Mets added to their stable crop of infielders on Thursday, agreeing with Jed Lowrieon a two-year deal worth $20 million. 
For Lowrie, this is a return to the National League, as he was with Houston in 2012 (its final year in the NL) before spending the next six in the AL with Houston and the A's.  
But back in 2009, Lowrie, then a 25-year-old for the Red Sox, crushed the very first MLB home run in Citi Field history -- a grand slam that sailed deep into left-center against left-hander Oliver Perez: 

Lowrie's slam gave Boston a quick 6-0 lead in the first inning of the exhibition game, en route to a 9-3 win that also featured a three-RBI performance from Kevin Youkilis (and his Hall of Fame-worthy batting stance). 
The first homer at Citi Field in an official game came on April 13, when the Padres' Jody Gerut lined one over the wall in right field. 
Lowrie's exhibition game grand slam is noteworthy not only because of its place in Mets history, but also for the fact that Lowrie has gone on to demonstrate a greater power stroke as a lefty (76 home runs) than from the right side of the plate (28), though he definitely can muscle up from that side every now and then. 
Now finding himself in a lineup that boasts fellow slugging infielders like Robinson Canó and Todd Frazier, it shouldn't be long until we see Lowrie hitting the ball all over the field in Queens as well.
