Pelfrey not a road scholar

The New York Mets and San Francisco Giants square off in this week's Sunday Night Baseball (ESPN, 8 ET) matchup.

Mike Pelfrey gets the ball for the Mets and enters the game with some historic numbers. Pelfrey has a 3.53 career ERA at home and a 5.44 career ERA on the road. According to Elias, Pelfrey has by far the largest discrepancy between his home and road ERA (in which the road is higher) among active pitchers (minimum 750 IP).

Next on that list would be Wandy Rodriguez (3.40 home, 4.89 road). This season, Pelfrey is 3-0 with a 2.96 ERA at home and 2-7 with a 6.05 ERA on the road. His 5.44 career ERA on the road is the fourth highest among active pitchers (min. 250 IP).

If there's one thing the Giants are not afraid of this season, it's close games. The Giants are 25-12 in one-run games this season, which puts them on pace for 45 one-run wins. The 1978 Giants hold the MLB record for most wins by one run with 42.

Nineteen of those 25 wins in one-run games have been at home. They are on pace for 37 one-run wins at home.

The franchise record (since 1901) for one-run wins at home is 24 in 1978 (24-10). The modern MLB record (since 1901) for one-run wins at home is 28. Of the three teams to do that, two won the World Series: the 1940 Reds and the 1943 Yankees. The third, the 1974 Orioles, lost in the American League Championship Series.

If there's one thing the Giants are afraid of this season, it's scoring runs at home. The Elias Sports Bureau tells us that San Francisco is the only team in the majors that has yet to score more than six runs in a home game this season. Every other team has had at least three such games, with Texas leading the way -- scoring six or more runs in 21 home games this season.

The Giants’ current single-season streak of 43 consecutive home games scoring six or fewer runs is the longest since the 1942 Phillies had a 55-game streak from May 23 to September 27. And it’s the longest to start a season since the Pirates did it in their first 42 games of the 1917 season.
