Who will win Braves vs Mariners today: Braves moneyline (+128)
The best team in baseball is a heavy underdog, but it's not as if the Atlanta Braves are suddenly struggling. The Braves opened their road trip with a three-game sweep in Colorado.
The Seattle Mariners must be blazing hot then, right? Nope. The Mariners were swept by the then last-place Royals in three straight at home.
It’s a road game for the Braves — but they’re 13-4 away from home.
There's not even a terrific pitching mismatch, as Atlanta rookie JR Ritchie has a lower ERA (2.92 to 4.03) and hits per nine innings (7.3 to 9.7) than Seattle veteran Logan Gilbert.
COVERS INTEL: Gilbert’s line is buoyed by four starts against losing teams. In his three games against teams over .500, he has a 6.75 ERA, while opponents are hitting .310 with an .852 OPS.
Braves vs Mariners Over/Under pick: Under 8 (-120)
Both teams have suffered major injuries to players they’re counting on to contribute at the plate.
The Braves put Ronald Acuna Jr. on the injured list after he left a game over the weekend with hamstring tightness.
Meanwhile, Seattle might be close to putting Cal Raleigh on the injured list with soreness in his side. He had an MRI and was held out of the last two games. The team said Sunday that an IL stint was possible.
The Mariners scored 10 total runs over their latest weekend series and have plated five or less in seven of their last 10 overall.
