C: John Buck (.228/.276/.496, 10 HR, 30 RBI): B+
It would be crazy to think that the Mets expected this kind of production from Buck when acquiring him along with the young pieces in the R.A. Dickey deal with Toronto.
Considering the inconsistency of the rest of the lineup outside of David Wright, the Mets would be far worse without the April posted by their veteran catcher. He's cooled off but handles the pitching staff well, has enough pop to hit 10-15 more home runs this summer and will hold the position well until Travis d'Arnaud is ready.
1B: Ike Davis (.169/.261/.288, 4 HR, 9 RBI): F
Unacceptable: While Davis may turn out to be a slow starter for the rest of his career, his lack of production or professional at-bats are killing New York's lineup.
Terry Collins deserves some heat for Davis' mental approach—flip-flopping him from bottom-of-the-order, to platoon duty to cleanup hitter can't help—but ultimately, Davis needs to learn to recognize the difference between balls and strikes.
2B: Daniel Murphy (.279/.315/.407, 2 HR, 16 RBI): C
Murphy has been labeled a hitter without a position since his arrival in 2008. Over the years, he's clearly put in the work to become an acceptable second baseman. If his bat were to live up to past expectations, New York could have a tremendous building block.
Instead, he's been almost perfectly average at the dish since the start of the 2012 season. A 103 OPS+ isn't worthy of a benching, but it's also far from anything to be excited about.
SS: Ruben Tejada (.227/.301/.295, 0 HR, 10 RBI): D
We're now 1,280 plate appearances into the Ruben Tejada experience in New York. With a .659 career OPS, it's clear that the Mets don't have a world-class bat on their hands.
Of course, Elvis Andrus hasn't been a much more dynamic hitter in his young career, but Texas just handed him a contract that could exceed $100 million. The difference? World-class defense. Andrus plays it, Tejada doesn't.
3B: David Wright (.296/.414/.512, 5 HR, 24 RBI): A+
If there's one reason to pay money to watch the 2013 Mets every night, it's their franchise third baseman. Despite playing in the media capital of the world, Wright is actually underrated.
Since his first full season in the majors, no full-time third baseman has posted a higher WAR. His .382 wOBA ranks third during that span behind only immortals named Alex Rodriguez and Chipper Jones.
Thus far in 2013, months after signing a long-term contract to stay with New York through his prime, Wright is in the Top 10 for OBP and playing his way into the All-Star Game at Citi Field.
UTL: Justin Turner (.310/.349/.362, 0 HR, 5 RBI): B+
Turner has made the most of his spot duty along the infield, giving the Mets a versatile bat to plug in when needed. If Ike Davis continues to struggle against left-handed pitching, Terry Collins could give Turner more opportunities to shine.
