MIAMI — If Atlanta Braves fans held their breath when Ronald Acuña Jr. was taken out of Thursday’s 9-3 win over the Miami Marlins because of thumb pain, that’s totally understandable. Acuña just returned from the injured list this week, plus offensive catalyst Drake Baldwin was sidelined with an oblique strain two days ago.It appears Braves fans can breathe easy. Although he had been unable to move his left thumb, X-rays came back negative not long after he was replaced in the bottom of the sixth inning. Afterward, he already expected to be in the lineup when the Braves open a series with the Washington Nationals at Truist Park on Friday.“I didn’t have to convince Walt (Weiss, the manager),” Acuña said in Spanish. “Or else we would have four outfielders playing in the field.”Acuña recently missed two weeks with a hamstring strain, but his absence didn’t keep the Braves from winning games. A strong offense, powered in part by Baldwin, helped them maintain the best record in the majors.With Baldwin now on the injured list, Acuña’s presence is even more crucial.“There’s a lot of excitement when he’s in the game,” Weiss said. “Because he might do something you haven’t seen before.”Look no further than the first inning Thursday for proof. Acuña opened the game with a routine ground ball off Sandy Alcantara — likely one of the trade deadline’s most coveted pitchers — but beat the throw from short with a sprint speed of 30 mph. Five pitches later, Acuña greeted Michael Harris II at home with a “making it rain money” celebration after scoring on his teammate’s two-run homer.
