MIAMI -- With a perfect ninth on Friday, Mets closer Jason Isringhausen collected his second save of the season and moved within five of 300 on his career.
One of the reasons the 38-year-old right-hander decided to pitch this year after his comeback from a third Tommy John surgery in 2010 was to reach that milestone.
At 33 2/3 innings in 2011, Isringhausen is less than 10 frames shy of how many he pitched in his last full season, which came in 2008 with the Cardinals.
"We've reached that time of the year where obviously we'll continue to be careful and monitor things," Mets manager Terry Collins said. "It's no longer, 'Hey look, let's try to get him through the year.' We're at that point."
Collins said that the veteran wants to be put into games and will let his skipper know if anything's up.
"I think in his new role obviously his frame of mind has changed a little bit more. There's probably a lot more focus and concentration," Collins said. "He has to know now that he might be in there three, four days a week."
Meanwhile, Bobby Parnell continues to enter ballgames in a setup role during key situations.
"We're trying to do it in a process that works for everybody. I think there's going to be a time when Bobby pitches the ninth inning," Collins said. "I don't think there's any doubt that's going to come."
"As we've seen [in] the last three games Bobby Parnell has pitched they've been huge innings -- even though it's been the eighth inning -- because [of] who he's had to get out in those games and shut those games down, and he's done a good job doing it."
Bay bats seventh vs. Marlins Saturday
MIAMI -- After missing the past two games with a tight right hamstring, Jason Bay was back in the lineup Saturday night against the Marlins.
The three-time All-Star, who is batting .232 with six homers and 29 RBIs in 71 games this season, was in the seventh spot of the order for the first time this year.
"Due to the way we've played and the way Justin Turner's handled the second spot, [we] try to juggle the order a little bit so we don't have and exploit the other left-handed relievers on the other team," Mets manager Terry Collins said. "Don't exploit our left-handed lineup."
The Marlins have two southpaw relievers, Randy Choate and Mike Dunn. In Saturday night's lineup, the Mets had lefties Daniel Murphy and Jose Thole as well as switch-hitters Jose Reyes and Carlos Beltran.
On the season, Bay has 79 at-bats in the cleanup spot, 113 in the fifth slot and 67 sixth in the order.
"I know he doesn't care. I know he told me yesterday, 'I'm ready to play tomorrow' and I said, 'You're in there,'" Collins said. "I thought about the lineup today, who's pitching. I looked at all the variables and said, 'This is where I think he fits best in the lineup.'"
Collins cites what Bay did in seven games against the Dodgers -- two homers and six RBIs -- as something he hopes happens again to wake up Bay's bat.
"When he starts swinging the bat obviously we have to get him in the mix," Collins said. "When he does what he did in Los Angeles I've got to move him up in the batting order."
Mets manager Terry Collins said that if he decides to give Jose Reyes a day off, Justin Turner would move from second to start at shortstop.
Nick Evans was designated for assignment on Friday when David Wright was reinstated from the 15-day disabled list.
Outfielder/first baseman Mike Baxter, who was claimed off waivers from the Padres on Friday, was optioned to Class A Lucie.
