NEW YORK -- The grand slam, baseball's ultimate offensive weapon, was on display the Yankees' 4-0 win over the Mets on Sunday at Yankee Stadium in what was a confrontation between the irresistible force and an exceedingly movable object. The slam Mark Teixeira hit against Johan Santana in the third inning was the Yankees' seventh and the seventh allowed by the Mets this season. No team other than the Yankees has hit more than four slams, and no team other than the Mets has allowed more than four this season.
Since the Mets hit 10 grand slams -- the most in the National League and the most in their history -- in 2006, slams have not treated them well. They have hit merely eight since '06, and none this season. Through Saturday, the Mets, Giants, Rockies, A's and Blue Jays were the only teams without a slam.
The Mets went without a slam in 2007, as they had done in 1965, 1974 and 1979.
The seven slams by the Yankees this season equal the most by the team since 2004, when they hit nine. The club record is 10, established in 1987, the first "Year of the Home Run." Don Mattingly was responsible for six of the 10.
Teixeira's slam was his first with the Yankees and the fifth of his career.

Santana has allowed three grand slams -- Teixeira, Shane Victorino and Josh Willingham hit them -- this season, more than 23 teams. Santana had allowed two before this season, Michael Young and Felix Hernandez.
Grand slams hardly are the only bases-loaded difference between the two New York teams. Consider these numbers, with the bases loaded, from this season -- the Yankees' total bases with the bases loaded equal the Mets at-bats in the those situations:
The Mets have 13 hits in 60 at-bats, a .217 average, for a total of 16 total bases and a .267 slugging percentage. The Yankees are 37-for-88, with 60 total bases, a .420 batting average and a .682 slugging percentage.
The last time one grand slam provided all of the runs in a game occurred exactly six years prior, according to Elias Sports Bureau. The Giants' Edgardo Alfonzo hit a slam off Mike Timlin of the Red Sox in a 4-0 San Francisco win on June 20, 2004.
The only other time in Mets history that they lost a 4-0 game on a grand slam was on June 23, 1975, when Ted Simmons of the Cardinals hit one against Jon Matlack at Shea Stadium.
