ATLANTA — Tyler Glasnow had waited long enough to return to a big-league mound, but he stewed more and more after each pitch. It took 111 days for Glasnow to pitch again for the Los Angeles Dodgers, and he wound up stuck in a first inning that felt as if it might never end.Two runs had scored by the time pitching coach Mark Prior came out for a mound visit. Prior’s trip amounted to more of a breather than anything else, as the Dodgers could not afford the inning falling apart. Glasnow finally got out of it on his 35th pitch. Then Glasnow showed something. He did not crumble.“He did everything he could to prevent runs tonight,” manager Dave Roberts said.Tuesday night felt overdue. Glasnow pitched for the first time since May, after dealing with lingering back spasms.“It felt like a long time,” Glasnow said.Not long ago, a meltdown by the gifted right-hander in that shaky first inning wouldn’t have been surprising. Glasnow steeled this time, mixing in his slider to keep hitters off his fastball after being too predictable early.Soon, Atlanta Braves batters couldn’t hit either pitch. They swung and missed seven times in the second inning as Glasnow struck out the side. He needed just 54 pitches to record the final 14 outs of his start, allowing just a pair of hits along the way.When Glasnow’s day was done, Roberts told him it was good to have him back.“How he navigated that first inning to not let it spiral, reset,” the manager said.Glasnow’s five innings were not enough Tuesday, as Atlanta won 4-3. The Braves strung their last big hit in the eighth inning, and the Dodgers failed in three attempts from the middle of their order to get Shohei Ohtani home after he led off the inning with a triple.Freddie Freeman waved over a Raisel Iglesias changeup. Mookie Betts couldn’t get his soft groundball past the infield grass, much less past Mauricio Dubón at short. Tommy Edman flied out to end the night and a chance to gain more ground toward a first-round bye in the National League postseason picture.
