Pelfrey has struggled in his first three starts, going 0-2 with a 7.90 ERA. The 6-foot-7 right-hander gave up six runs on eight hits in three innings on Wednesday as the Rockies rolled to an 11-5 victory.
Both Minaya and Randolph agreed that Pelfrey's having problems, but said they'll keep a close eye on the situation. Pelfrey will get at least one more start, and they won't put a timetable on when the 23-year-old needs to get better by.
"Right now, he is, at this point in time, our fifth starter today," Minaya said before Friday's series opener with the Nationals. "With these situations, with young pitchers, you're always talking about [it]. I always reserve [the right] to think these things through and ... we continue to talk about this."
Pelfrey has given up 12 earned runs in 13 2/3 innings in his three starts. He's struck out six, but walked seven batters.
Minaya said that, as a general manager, he has to look at the short- and long-term issues, and there's no defining moment to say someone like Pelfrey is or isn't ready.
Pelfrey is scheduled to make his next start on Monday against the Marlins.
A time to learn: Some members of the Mets' traveling party did something meaningful away from the baseball field Friday morning when visiting the Holocaust Museum in Washington.
They went for a few hours to experience a museum dedicated to the memory of the six million Jews who lost their life at the hands of German leader Adolf Hitler in the Holocaust during World War II.
"It's a new feel, a new, vibrant feel of a dismal part of history," said outfielder Shawn Green, who is Jewish. "It's very heavy and emotional, and it's very educational. I learned a lot about the rise of Nazi power. To me, it was amazing how fast the masses were sort of brainwashed into succumbing to a leader like that."
Green clearly was moved by what he saw in the museum and talked with reporters for several minutes about it.
"It's also scary to think about the potential about something like that happening again," Green said.
A big hit: The Mets have gotten plenty of solid pitching this season, but they've also benefited from plenty of offensive punch.
They came into Friday's game leading the Major Leagues with a .295 team average. The Mets also are third in the Majors with 116 runs scored, with an offense that keeps pounding and takes pressure off the club's pitching staff.
"We've got a good offense," said third baseman David Wright. "We can beat you a number of different ways. We can come at you with a number of different weapons."
Whoops: The three-run homer that Oliver Perez gave up to Washington's Austin Kearns was the first time this season the Nationals have scored in the first inning.
Whoops, again: When Washington starter Matt Chico singled off Perez in the second inning, it was his first Major League base hit.
This date in Mets history -- April 28: En route to a Mets 8-6 victory at the Polo Grounds, Frank Thomas, Charlie Neal and Gil Hodges hit home runs in successive at-bats against Pirates starter Jim Owens in the sixth inning on this date in 1962. The Mets, in the 14th game in their history, hit two others -- one by Neal -- to establish a club record that, though equaled 15 times, stood until Opening Day 1988, when the team hit six in Montreal.
Lindsey Nelson broadcasted a Mets-Astros game from the hanging gondola, which was 208 feet above the field, at the Astrodome on this date in 1965. The Mets lost 12-9; neither team hit a home run.
Rusty Staub, who entered the game as a right fielder in the 12th inning, made a running catch near the right-field line for the final out of the game in the 18th inning of the Mets' 5-4 victory against the Pirates at Shea Stadium on this date in 1985. Staub hadn't played the outfield since June 22, 1983, and never played it again.
Coming up: Tom Glavine, who had his 294th career victory within reach against the Braves on Sunday, makes a second run at it Saturday night at 7:05 p.m. ET at RFK Stadium. Jerome Williams, winless in four decisions, starts for the Nationals.
