Mets
David Wright: Since he made his debut in 2004, Wright has been a fixture at third for the Metropolitans. And despite his wacky 2009, he deserves a spot on this list for his time in Queens. His .309/.389/.518 splits are excellent (and are all among the top 23 among active players) and he's added to that a .391 career wOBA. That wOBA total is 10th among all 3B (min 2500 PA) and ranks ahead of such names as Eddie Matthews, Miguel Cabrera, Harmon Killebrew, Kevin Youkilis, Wade Boggs, and George Brett at the hot corner. In 2007 and 2008, Wright won the Gold Glove and Silver Slugger both years. He also finished in the top 9 in MVP voting in each year from 2006-2008. The big question for Mets fans is "can Wright rebound from a low power output in 2009?" Even without answering that question here (he only hit 10 HR and 52 XBH total), the truth is that the guy still hit .307/.390/.447. But this is a guy who averaged 73 XBH a year from 2005-2008 which is impressive for a third baseman. He just turned 27 in December so he should have plenty of time to build on these credentials. But even through age 26, he looks very similar to Scott Rolen and Duke Snider and adds the element of speed to his repertoire as well (119 SB). Since he broke into the league, Wright has been worth 32.0 WAR according to FanGraphs and has been an invaluable player to the Mets. (picture from the New York Times)
Howard Johnson: When David Wright needed some help with hitting this off-season, he went to hitting coach Howard Johnson. Why? Because HoJo was a pretty good hitter back in his day. A .251/.341/.459 hitter with the Mets, Johnson held his own at the hot corner. His two best seasons were 1989--when he led the league in runs with 104, hit .287/.369/.559 with a .416 wOBA (a career high), 41 2B (a career high), 36 HR, 41 SB (a career high), and a 169 OPS+ (also a career high)--and 1991--when he led the league in homeruns and RBIs with 38 and 117 respectively (both career highs), scored 108 runs (a career high), and hit a major league leading 15 sac flies. Both years he finished 5th in the MVP race, made the All Star team, and won the Silver Slugger. HoJo was originally drafted by the Yankees in the 1978 amateur draft but did not sign. He was eventually drafted in the first round by the Tigers before being dealt to the Mets in 1984. Johnson still leads all Mets 3B in HR, RBI and SB. Johnson also became the first Naitonal League infielder to go 30-30 in a season in 1987. (picture from JetsandMets.com)
Just missed: Robin Ventura (who only played 444 games with the Mets and his numbers lagged behind the two Mets candidates) and Wayne Garrett (played more games at 3rd than Wright but was nowhere near the offensive producer)
