ATLANTA -- For the second time this season, a game between the New York Mets and Atlanta Braves was postponed because of rain.Heavy rain in the area caused play to stop at 8:44 p.m. ET, with the Mets leading 3-1 with two outs in the fourth inning. The game was postponed after a delay of 1 hour, 59 minutes.The makeup date has not been determined. The Mets have two future series in Atlanta, one in June and another in September. They already have a double-header scheduled for Sept. 25 to make up the earlier rainout in New York.The Braves will open a three-game series on Friday against St. Louis. New York returns home to open a three-game set against Miami.The rainout caused both teams to burn a starting pitcher - Atlanta's Jaime Garcia and New York's Zack Wheeler.Atlanta will keep its starting rotation intact for the series against the Cardinals. Right-hander Mike Foltynewicz (0-3, 2.81 ERA) will open the series against St. Louis right-hander Lance Lynn (3-1, 2.45).New York will start right-hander Rafael Montero (0-2, 9.45), who was recalled to take the spot left open by the injury to Noah Syndergaard. He will be opposed by Miami's Tom Koehler (1-1, 5.40)."First day he was here, he had a huge reputation of great command," New York manager Terry Collins said about Montero's first start of the season. "He got behind in the count early and now he's got to come on the plate and that's what's damaging."If you didn't you walk guys and at this level you're asking for danger if you keep putting guys on. We know his stuff plays, we know his stuff is very good, so trust it ... throw it in the strike zone."Atlanta sent right-hander Matt Wisler to Triple-A Gwinnett after he was roughed up Wednesday. Wisler was 0-0 with a 12.60 ERA in four relief appearances since being recalled on April 23. Wisler will return to the starting rotation at Gwinnett."I still like him," Atlanta manager Brian Snitker said. "His stuff is too good. We're going to need him again before the year is over."The Braves recalled left-hander Sam Freeman from Triple-A. In nine relief appearances for Gwinnett, Freeman had a 0.87 ERA with eight strikeouts in 10 1/3 innings. He has worked in 142 major-league games in five seasons with St. Louis, Texas and Milwaukee."He's throwing the ball over," Snitker said. "He's had good velocity. He's been efficient. The reports every night have been really good. He's not necessarily a matchup guy, either."NOTES: The Mets have won 13 of their last 17 games in Atlanta. ...
