ATLANTA— Alberto Callaspo hit a tiebreaking single in Atlanta's two-run fifth inning and the Braves held off Miami in the ninth inning to beat the Marlins 3-2 on Monday night in a game slowed by two rain delays.
Shelby Miller (1-0) allowed one run in five innings as the Braves bounced back from their first loss and handed the Marlins their sixth loss in seven games.
Before the game, the Marlins placed opening-day starter Henderson Alvarez on the 15-day disabled list with inflammation in his right shoulder and elbow.
Jason Grilli gave up a double to Martin Prado to open the ninth before striking out Michael Morse and Marcell Ozuna. After walking Jarrod Saltalamacchia, Grilli gave up a run-scoring single to Adeiny Hechavarria. Grilli struck out Jeff Baker on a called third strike to earn his fourth save.
A single by pinch-hitter Jace Peterson and double by Eric Young Jr. knocked Marlins starter Matt Latos (0-2) out of the game in the fifth. Callaspo hit Sam Dyson's first pitch to center field to drive in Peterson for a 2-1 lead. Nick Markakis followed with another run-scoring single.
The start of the game was delayed 52 minutes by rain. There was another delay of 39 minutes in the middle of the fourth.
After walking Dee Gordon, Jim Johnson struck out Christian Yelich and Giancarlo Stanton to end the eighth.
Latos allowed three runs, two earned, on five hits and three walks in four-plus innings.
Yelich's groundout drove in Hechavarria, who reached on a single, in the third.
Yelich took a run-scoring hit away from Cameron Maybin in the second. With runners on first and second, Yelich made a leaping catch of Maybin's line drive in left field and held the ball as he tumbled onto the warning track. A video review confirmed the catch.
The Braves pulled even in the fourth with Christian Bethancourt singled, stole second, advanced to third on Saltalamacchia's throwing error and scored on a wild pitch from Latos to Andrelton Simmons.
Marlins manager Mike Redmond said losing Alvarez, a 2014 All-Star, to the DL was "definitely a concern."
Redmond said the initial plan is "calming down the inflammation and get him feeling good and healthy. How long it will be, I don't know."
Before the game, the Braves designated right-hander Juan Jaime for assignment and selected the contract of right-hander Sugar Ray Marimon from Triple-A Gwinnett. Jaime walked four while getting four outs in his first two games.
Marlins right-hander David Phelps was placed on the paternity list after his wife gave birth. He is expected to rejoin the team on Thursday and replace Alvarez in the rotation on Friday.
Stanton, who was 0-for-4, is hitting .130 with no homers.
Marlins: Backup catcher Jeff Mathis and reserve infielder Don Kelly landed on the 15-day DL. Each broke the ring finger on his right hand in Sunday's game. ... Right-hander Jose Urena was recalled from Triple-A New Orleans to replace Phelps. Also coming up from New Orleans were catcher J.T. Realmuto, infielder Reid Brignac and right-hander Carter Capps, who pitched the eighth inning.
Marlins: RHP Tom Koehler will look for his first win against Atlanta on Tuesday night. Koehler is 0-3 with a 3.13 ERA in 10 games, including seven starts, against the Braves.
Braves: RHP Trevor Cahill, acquired from Arizona on April 3, will make his Braves debut. The Braves need Cahill to provide depth and stability to a rotation that has lost Mike Minor indefinitely with a sore shoulder.
