Frankie leaves to tend to injured brother

Closer expected to be back by Monday's season opener

PORT ST. LUCIE, Fla. -- Jose Reyes and Daniel Murphy are certain to be absent from the Opening Day lineup, and though it didn't appear that it will further impact the Mets' plans for Monday, closer Frankie Rodriguez left the team on Thursday and returned to his native Venezuela, reportedly after he received news that his brother was injured in a serious car accident.

"There was a car accident with one of his family members. I'm waiting to hear from [Rodriguez] to see how he's doing. It's pretty serious," Rodriguez's agent, Paul Kinzer, told the New York Daily News. "I found out [Wednesday] night. Hopefully it works out."

Kinzer told the Daily News that the brother was hospitalized, and ESPNNewYork.com reported that he is expected to be fine and that Rodriguez plans to return to New York on Sunday, according to sources.

Kinzer said he believed Rodriguez would be back in time for Monday's season opener against the Marlins at Citi Field.

"I know he's planning on being there for Opening Day," said Kinzer.

General manager Omar Minaya said on Thursday: "We expect to have him available" for Monday. But Minaya hardly was certain.

The Mets are scheduled to work out at Citi Field on Sunday.

Rodriguez's absence from a bullpen still unsettled would create a great unknown. As of Thursday morning, the club hadn't decided who will fill the eighth-inning role.

Thursday notes from Port St. Lucie

PORT ST. LUCIE, Fla. -- Sean Green has made a late run that has enhanced his chance of winning a position on the roster. Bobby Parnell hasn't.

Kiko Calero pitched an inning without allowing a home run Thursday.

The Mets made no personnel moves Thursday. General manager Omar Minaya said they were "taking everyone" to the west coast of Florida, and that it is likely that no moves will be made until Saturday, perhaps Sunday. Frankie Rodriguez, Jose Reyes, Daniel Murphy, Carlos Beltran and Kelvim Escobar won't be with the team in St. Petersburg.

Prevention and Recovery has made the cut. Charlie Samuels, the clubhouse manager, packed four P&R signs to bring to Citi Field.

A few April Fools' Day notables: Today is the 30th anniversary of Mets PR man Jay Horwitz's hiring. It's the 25th anniversary of the infamous Sidd Finch hoax in Sports Illustrated. And it's Rusty Staub's 66th birthday.
