Willie Harris had a tiebreaking two-run pinch-hit single in place of debuting Josh Satin and the Mets won Sunday's rubber game against the Nationals, 6-3, Sunday afternoon.

The Mets now make their final trip to Sun Life Stadium, which the Marlins share with the Miami Dolphins. The Marlins move to a baseball-only stadium with a retractable roof in 2012. Read the Mets-Marlins series preview here.

Monday's news reports:

• Terry Collins told the Daily News his recommendation is for his entire coaching staff to return intact. Hitting coach Dave Hudgens has a two-year deal. As for pitching coach Dan Warthen, the lone remaining member of the 2010 staff, Collins said: "Danny has done an excellent job. He gets them ready. He is sharp. It's a good situation when the players like the coaches. They have fun. They laugh. They have great communication with each other. That helps a lot. ... I do think they should all be back. They all did a great job, and there is something to be said for stability."

• Satin started at first base and went 1-for-2 in his major league debut. He singled in his first plate appearance, off ex-Met Livan Hernandez.

• Ike Davis will meet the Mets in Miami. Optimism abounds that he will avoid surgery on his troublesome left ankle. Davis worked the past three days in Port St. Lucie, Fla., taking grounders, swinging off a tee and with soft tosses, and playing catch. Read more in Newsday.

• Jose Reyes received his first day off Sunday, as a late scratch once it was deemed Ruben Tejada was ready to return from a hand injury. Josh Thole also returned, as a pinch-hitter. Thole, like Tejada, was forced to leave Thursday's game in New York. Thole had been struck on the thumb/wrist with a fastball from Miguel Batista while expecting a slider.

• Johan Santana should throw a bullpen session Tuesday in Miami for Mets staff. He will pitch in a minor league playoff game Friday. If all continues to go well, and the Mets' affiliates are done with the postseason after that, Santana could find himself in a major league game at least for a couple of innings as soon as the following week.

• Outfield coach Mookie Wilson told Mike Puma this about Lucas Duda's right-field play in the Post: "He's not your typical outfielder. I don't want him to think he has to try to make the (highlight) play. Just let the game come to him and let him understand it's going to take reps so that he feels comfortable. His defensive ability, it is what it is. He runs well enough, he has plenty of arm, there is not a question about that. It's about trying to understand it's going to take reps for him to be completely comfortable. Just don't panic." Duda aggressively went after Ryan Zimmerman's flare to right field Saturday, allowing the ball to get behind him and the winning along with the tying run to score. On Sunday, Duda misread Danny Espinosa's liner and the shot sailed over him for a double.

• Warthen had this to say about Mike Pelfrey's high pitch count (106 in 4 2/3 innings), according to the Record's Steve Popper: "(When) he goes out there and tries not to give up runs, he starts getting too fine with his pitches. … He’s got the ability but you can’t strike anybody out until they have two strikes on them. He has the pitches, has enough of a slider, has enough of a fastball, but he has to be ahead in the count. Out of the stretch position he just throws too many balls.”
