Braves was my first thought too but I dont think they ever had 3 in the same season. Although I'm not 100% clear on what the question was. "The second game in a row that they've pitched three 20 game winners"
Were those 20 game winners from the same team and both "current" year? Was it 3 in BOTH games so 6 total?
If we can mix and match I'm guessing the Braves had some games with Smoltz closing where another former 20 game winner was brought in for relief as well.
Who is the only 4x batting champion not in the Hall of Fame?
Both Oliva & Rose are 3x batting champs. But Pitbull nailed it —.it’s Bill Madlock!
