It has been nine years since a New York Met has hit at least 40 home runs in a season: In 2006, Beltran hit 41. Before that, Piazza hit 40 in 1999, and Hundley hit 41 in 1996. However, before 1996 no Met had hit 40. Darryl Strawberry came closest in 1988, hitting 39.
Since 2006, the most homers hit in a season by a hit is 32, done in 2012 by Ike Davis. Since leaving the Mets in 2014, Davis has hit only 13 homers.
On the current team, after emerging last season as a power hitter with 30 homers, Lucas Duda has regressed. Through 88 games this season, he has hit only 12. If he continues at that pace and has the same number of plate appearances as in 2014, Duda's projected to knock 19 balls out of the park in 2015. If that is the case, Duda might regret not signing the contract the Mets offered before this season began.
