Glavine said, "I'm not comfortable talking about it, but I hope so," when talk turns to the statistic that has been essentially an automatic entry into the Hall of Fame.
Glavine's start Friday was pushed back a day because of a rainout.
The Giants are one of two teams to beat him this season (Atlanta, on April 19, is the other) and the only one to score more than three runs off him.
Glavine is 4-1 with a 1.38 ERA in six starts at Shea Stadium, and he's on a 6-0 run with a 2.27 ERA.
For much of his career, Glavine has lived on the outside corner with his fastball and change-up, but has adjusted and is challenging hitters more inside with breaking balls.
REPLAY: Friday's game against the San Francisco Giants was rained out and will be made up Saturday as part of a single admission doubleheader. First pitch at Shea Stadium is scheduled for 1:20 p.m. ET.
CF Carlos Beltran, who fouled a ball off his right knee Wednesday, got an extra day to mend and could play Saturday, although he was not in New York's starting lineup for Game 1 of the twinbill.
LHP Tom Glavine will be seeking his seventh straight win Saturday against San Francisco. Glavine was 5-0 with a 2.94 ERA in May.
1B Carlos Delgado is in a miserable slump, with his average dropping from .299 to .208 during May.

LF Cliff Floyd appears to have shaken off a season-long slump by raising his average 36 points to .234 with three homers over the past two weeks.
BY THE NUMBERS: 91 -- Points 1B Carlos Delgado's average dropped during the month of May.
QUOTE TO NOTE: "I've never seen him blame nobody. We got to help him with runs. Make it easy for him. But it's not gonna be easy, because he's our ace and most of the time he faces the other team's ace." -- Mets INF Jose Valentin, on the lack of support RHP Pedro Martinez is getting. Martinez is winless in his last six starts, with five no-decisions.
