Game Snapshot

• Matchup: Kansas City Royals at Miami Marlins
• Date & Time: July 20, 2025 · 1:40 p.m. ET
• Starting Pitchers: Kris Bubic (7-6, 2.48 ERA) vs Janson Junk (4-1, 2.68 ERA)
• Stadium: loanDepot Park, Miami, FL
• Broadcast: FDSN-KC

Key Storylines

• Pitching form: Kansas City’s Kris Bubic has been excellent for the Royals. He is 7-6 but his 2.48 ERA suggests that he has been better than his win-loss numbers show. Janson Junk has posted a 2.68 ERA on the season and is off to a 4-1 start to his season. Both of these pitchers will look to outduel the other on Sunday.
• Bullpen usage: The margins in this series have been incredibly slim. But so far it has been the Miami bullpen that has come through when they have needed to.
• Recent team streaks: The Royals have lost their last two games and four of their last five. The Marlins are on a four-game winning streak and can secure a sweep of the Royals with a fifth straight win.

Final Thoughts

Both starting pitchers in this game have been excellent for their respective teams. But I am going to give the upper hand to Janson Junk and the Miami Marlins in this game. They have been making winning plays when they have needed to in this series thus far. I expect that to continue and for them to earn a sweep at the expense of the struggling Royals.
