The Atlanta Braves head to Petco Park on Monday, June 22, 2026, for a 10:10 PM ET first pitch against the San Diego Padres, with right-hander Grant Holmes drawing the start opposite Padres ace Michael King. It's a late-night West Coast challenge for a Braves club that needs to show it can handle elite pitching — and King is exactly that kind of test. The game airs nationally on ESPN and ESPN App, so the whole country gets to watch Atlanta make its case.

Pitching Matchup: Grant Holmes vs. Michael King

Grant Holmes gets the nod for Atlanta, and this is the kind of start that will tell you something real about where he stands heading deeper into the 2026 season. Holmes has the stuff to keep lineups off-balance, but Petco Park under the lights against a loaded San Diego lineup is a genuine proving ground. He'll need his command to be sharp from the first inning — this is not a rotation where you can afford to fall behind early and grind through traffic.

Michael King on the other side is a legitimately tough assignment. The Padres right-hander has established himself as one of the better starters in the National League, and he thrives at Petco, where the park's spacious dimensions work in a pitcher's favor. Atlanta's hitters will need patience at the plate and a willingness to work deep counts to get to King early and make the Padres bullpen a factor.

San Diego Lineup: Threats Up and Down the Order

The Padres are sending out a lineup that demands respect from the first batter to the ninth. Fernando Tatis Jr. leads off from right field, followed by Jackson Merrill in center — that's a dangerous top two that can set the table or beat you with one swing. Manny Machado hits third and remains one of the most complete hitters in the game. Gavin Sheets slots in as the cleanup DH, with Ty France at first and Xander Bogaerts at short rounding out a middle section that punishes mistakes.

Keys to Watch for Atlanta

• Holmes's command early: Getting through the Tatis-Merrill-Machado portion of the order without damage in the first two innings is critical. Walks and extra-base hits will snowball fast against this lineup.
• Working King's pitch count: Atlanta's offense needs to be disciplined. King is at his best when hitters chase. Making him throw strikes and hunting fastballs early in counts gives the Braves their best shot at getting into the San Diego bullpen.
• Handling the late start: A 10:10 PM ET first pitch on the West Coast is a grind. Focus and energy in the late innings could be a factor, especially if this game stays close into the seventh and eighth.
• Capitalizing on Bogaerts and the bottom of the order: Xander Bogaerts at six is still a hitter who can hurt you. Holmes cannot afford to let his concentration slip when he gets through the heart of the order — the threat doesn't reset.

Prediction

This is a tough spot for Atlanta. Petco Park, a late West Coast first pitch, and Michael King on the mound add up to a steep hill. Grant Holmes has to pitch the game of his life to keep the Braves in it, and that's asking a lot. San Diego's lineup depth is real, and King will exploit any inconsistency from Holmes. Look for the Padres to win this one, 4-2, but Atlanta's ability to keep it close and make King work deep into the game will be the real storyline to monitor heading into the rest of the series.
