Game Snapshot

• Matchup: Milwaukee Brewers vs Seattle Mariners
• Date & Time: Monday, July 21, 2025 at 9:40 PM ET
• Starting Pitchers: Brandon Woodruff vs George Kirby
• Stadium: T-Mobile Park, Seattle, WA
• Broadcast: ROOT Sports NW and FDSWI

Key Storylines

• Pitching form: Brandon Woodruff has looked good since starting his season late due to injury. Woodruff has a 1-0 record and a 2.61 ERA. This game will be a significant test for him in his comeback. George Kirby of the Mariners has rebounded from early struggles. He is 4-4 and has a 4.50 ERA. But you would expect him to continue to rein in that ERA here.
• Bullpen usage: Milwaukee’s relievers have a slightly higher ERA than those of the Mariners do. Still, both teams have bullpen ERAs just under 4.00 for the season. We should see an evenly-matched bullpen battle in this contest.
• Recent team streaks: The Brewers are riding a 10-game win streak. Mariners have won four of their last five but had their winning streak snapped by the Houston Astros on Sunday.

Final Thoughts

Brandon Woodruff has been very good for the Brewers since making his delayed debut this season. In this game, I will take Woodruff and the Brewers to get the job done on the road, as I have been very impressed with the play of the Brewers on both sides of the All-Star break.
