The Atlanta Braves came out best after an action-packed eighth inning to defeat the San Diego Padres 6-5 on Saturday.

Down 5-2 in the bottom of the eighth following a four-run inning from the Padres, the defending World Series champions responded with a four-run inning of their own to split the opening two games of a three-game series.

Marcell Ozuna scored a home run and Austin Riley hit the go-ahead double in the response to hand the Braves the win, in what has been a sputtering start to the season.

Charlie Morton pitched solidly, striking out nine and giving up two hits over 83 pitches in six innings.

Atlanta have now won four of their past six games to move to a 16-18 record for the season.

Robert ruins Yankees win streak

Luis Robert drove home the winning run in the ninth inning to hand the Chicago White Sox a 3-2 win over the American League East-leading New York Yankees.

The Yankees were relentless at the plate over the opening two games of the series, scoring 25 runs but faced difficulty against Dallas Keuchel, who struck out three and gave up only four hits over 86 pitches.

While New York still hold the best record in baseball at 24-9, the loss ends a five-game winning streak.

Marte mashes Mariners

Patrick Mazeika hit the game-winning home run in the seventh inning, but Starling Marte was the star for the New York Mets in their 5-4 win over the Seattle Mariners.

Marte tripled, doubled, singled and claimed three RBIs from four at-bats for the Mets, who let a 4-0 lead slip when Jesse Winker tied with a three-run home run in the seventh inning.

Batting ninth, Mazeika had the final say however, mashing Andres Munoz inside the right-field foul pole for his second home run in the major leagues.

Atlanta Braves slugger Marcell Ozuna will be sidelined for at least six weeks after fracturing two fingers, the MLB franchise announced on Wednesday.

Ozuna was hurt during Atlanta's 3-1 win over the Boston Red Sox at Fenway Park on Tuesday.

The Gold Glove Award winner and two-time Silver Slugger sustained two fractured fingers – both the middle and right fingers of his left hand.

"Thank God, nothing more serious happened," Ozuna wrote via Instagram midweek. "Now wait six more weeks recovering."

Ozuna injured the fingers as he attempted to advance from second to third base, with his ring finger bending awkwardly as he grounded his slide and crossed over Red Sox third baseman Rafael Devers' left foot.

Braves manager Brian Snitker had hoped the slugger may have only dislocated his fingers after the initial X-rays did not reveal a fracture.

"I was hoping they wouldn't have found anything and he'd have been back in a few days after allowing the swelling to go down," Snitker said.

"This is a significant time to be without a big player on your team."

"I guess the good thing is there won't be a surgical process," he added. They just cast him up and it's going to take time."

Entering Wednesday's action, Ozuna had career lows for batting average (.213) and on-base plus slugging (.645).

Ozuna – a two-time All-Star – has only managed seven homers this season, with 21 runs and 40 hits with 26 RBI in 188 at-bats.
