BOSTON — The Boston Red Sox did something on Wednesday that they haven’t done in three weeks: Lose.After the Baltimore Orioles pounced on Red Sox rookie starter Eduardo Rivera for four runs in the first inning, Boston couldn’t muster one of its magical comebacks that has been customary in recent weeks.The Red Sox fell to the Orioles, 5-1, in the second game of a Wednesday doubleheader, snapping their win streak at 15 and costing them a chance to set a franchise record of 16 straight.Earlier in the day, a 6-3 win over Baltimore helped the Red Sox tie the longest win streak in club history, set in 1946 by a Ted Williams-led team that went to the World Series. Now, this 2026 team will sit alongside that group in the history books.In the midst of their improbable streak, the Red Sox had swept three straight road series before the All-Star break, besting the Los Angeles Angels, Chicago White Sox and New York Mets. They returned to action with a four-game sweep of the American League East-leading Tampa Bay Rays, and had taken the first two games against Baltimore. They had not lost a game since July 1.Shohei Ohtani is playing through a knee injury, when will he pitch again?Eno Sarris and Derek VanRiperRivera, the rookie pitcher, started in place of veteran Ranger Suarez, who was set to return Wednesday from a stint on the injured list. But Suarez, who had been dealing with a groin strain, fell ill earlier in the week. That illness — coupled with a few intense workouts as he tried to prepare for a return — set him back. The Red Sox turned to Rivera, who pitched well before the break, but struggled in his most recent outing Friday. It was more of the same Wednesday. Rivera recorded just two outs and was booed as he headed back to the dugout. The Red Sox then turned to beleaguered right-hander Brayan Bello in long relief.
