3. Timely Lineup
The 2015 Mets lineup is gaining momentum.
The 2006 Mets may have a much better lineup, but the 2015 Mets lineup has been on a roll in the second half especially after the acquisitions. Playoffs is all about momentum. And the Mets lineup in the second half has been one of the best. They may not have much speed but they have power with Cespedes, Duda, Granderson, and Wright.
Also, the Mets lineup has been more clutch lately too, getting big hits down the stretch. Their improved lineup is why the Mets ran away with the NL East in the second half.
