Former Seattle Mariners pitcher Jamie Moyer often said that solo homers won't beat you.

Seattle's Logan Gilbert proved that Monday night.

Gilbert allowed four solo shots, but the Mariners came away with a 5-4 victory against the visiting Atlanta Braves in the opener of a three-game series.

"Four of them is not ideal, but I guess it held true tonight," Gilbert said of the adage.

The interleague series will continue Tuesday night in Seattle.

Matt Olson hit his 300th career homer, and Drake Baldwin, Ozzie Albies and Austin Riley also went deep for the Braves, giving them a 4-0 lead through 5 1/2 innings.

Atlanta rookie right-hander JR Ritchie, a native of nearby Bainbridge Island, Wash., held the Mariners scoreless until the sixth. He walked the first two batters before allowing a three-run homer to Luke Raley.

Raley, mired in a 1-for-24 slump, took the traditional walk the length of the dugout with the Mariners' home-run trident, then sought hitting coach Edgar Martinez to give him a hug.

"He made some adjustments," Mariners manager Dan Wilson said of Raley. "Because of how hard he works and how much he cares, it's good to see."

The Braves brought in reliever Tyler Kinley, who walked Mitch Garver and allowed a two-run shot to J.P. Crawford that put Seattle ahead.

"Ritchie threw the ball really well ... he had a tough start to the sixth with a couple of walks. Kinley has been unbelievable for us; he's done a heck of a job and Crawford got him there," Braves manager Walt Weiss said. "We were trying to squeeze a few more outs out of Ritchie because we didn't have enough available (arms) in the bullpen. We were really light, and that's what happens."

So to recap: Three walks and two homers beat four solo shots.

"These guys play with a lot of heart, and tonight was no exception," Wilson said. "They fell behind and they came right back."

The Mariners snapped a three-game skid and handed the Braves just their fourth loss in the past 19 games.

Atlanta catcher Sean Murphy made his season debut after recovering from hip surgery last September. The Braves designated Jonah Heim for assignment to clear a roster spot and traded Heim to the Athletics for cash on Monday night.

"It's good to have Murph back; he's been a big part of this the past few years," Weiss said.

Tuesday's game will feature a pair of right-handers in the Braves' Bryce Elder (3-1, 1.88 ERA) against the Mariners' George Kirby (4-2, 3.00).

Elder took his second straight no-decision Thursday against visiting Detroit despite allowing one earned run on six hits over six innings as the Braves lost 5-2. He is 0-0 with a 3.00 ERA in one previous start against Seattle.

Kirby had a streak of three consecutive victories snapped when he took a no-decision Wednesday at Minnesota in a game the Mariners won 5-3 with three runs in the top of the ninth. He gave up two runs on eight hits over 5 2/3 innings.

Kirby is 1-1 with a 2.08 ERA in two career starts vs. the Braves.
