The 2-1 deficit the Rays ultimately couldn’t overcome in Thursday’s loss in Atlanta was created by some things they hadn’t done right more than anything they did wrong.Ryan Yarbrough gave them a strong start, allowing only two runs during a second-inning Braves rally that included a hit batter and a sacrifice fly. The Rays’ hitters were shackled much of the evening by dominating Braves starter Max Fried but had scratched out a run to halve the score.Which brought us to the ninth, when Kevin Kiermaier made a big mistake to thwart their bid for a dramatic rally.After Jose Martinez was robbed of a leadoff double by leftfielder Adam Duvall’s running catch, Brandon Lowe gave the Rays a chance with a single off Mark Melancon.Kiermaier, who was out of the lineup for the first time this season, was sent in to pinch-run, charged with using his speed to get into scoring position with Hunter Renfroe, who was 3-for-8 against Melancon, at the plate.Kiermaier broke for second on a 1-1 pitch, but rather than slide in, he inexplicably pulled up, raised his arms and jabbed his left leg at the bag, easily tagged out by Ozzie Albies.What happened?“Simple answer — I did what you can’t do and assumed,” Kiermaier said. “I thought it was (a) foul ball. I thought I heard the crack of the bat, and it was his glove, and that’s the dead-honest truth. But it doesn’t make it any better. You can’t do that.“They put me in to ... tell me to steal a base and get into scoring position, give us that better a chance of tying the game up. And I made a terrible mistake. It totally fooled me. Obviously, that can’t happen.”Kiermaier, who had tried running on the previous pitch but had to come back when Renfroe did foul off the pitch, said Albies’ positioning standing in his path contributed, but he didn’t think he was being deked, just confused. It was the second straight night Kiermaier was on a Zoom video call from Atlanta explaining a mistake, as he uncharacteristically missed a fly ball in Wednesday’s game that led to a run.Thursday’s play wasn’t the reason the Rays lost, as manager Kevin Cash pointed out they still would have needed a lot to happen, but it certainly kept them from having a last-ditch chance to win, as Renfroe then struck out to end it.Yarbrough had done just about everything he could to help them earlier.Held the Braves to the two runs. Kept traffic off the bases, allowing only two hits and three walks. Went deep, working into the seventh with 87 pitches.“We all thought he was outstanding,” Cash said. “Just kind of being himself, what he does.“The cutter was a big pitch for him. He went a while before he even threw a fastball, almost a time through the lineup without throwing a fastball, just kind of pinching off his cutter it seemed like. And then he brought the fastball in. So just mixing his pitches consistently and able to follow the game plan, he’s as good as anybody at being able to do that.’'In two starts, Yarbrough has made the most — aside from getting a W — of the rotation spot he badly wanted after spending much of the past two seasons working behind an opener. He went 5-1/3 scoreless innings Saturday in his season debut.“I feel, especially after the long (shutdown) we had there, to kind of come out like that and throw pretty well and put your team in situations to win both ballgames, I think that’s all you can really ask for,” Yarbrough said.“And I’m going to continue to do that and really stay aggressive, attack guys and ... continue to build off these two starts and hopefully take them into the rest of the year.”The Rays couldn’t do anything against Fried, the talented lefty, early on. They went down 14 straight before Mike Brosseau singled with two outs in the fifth — and then got picked off.They got another hit and a walk in the sixth, then put together what on this night counted as a rally in the seventh — a two-out double by Willy Adames, their first extra-base hit since Monday, to end Fried’s night, then a pinch-hit RBI single by Ji-Man Choi off reliever Luke Jackson.But that was it as the Rays’ offense has been productive but somewhat inconsistent thus far, not striking until later in games. Not by design, of course.“We recognize it,” Cash said. “I think the guys recognize it, that we’ve basically gone a time through the order and really not put any pressure on the pitcher or the defense. Just quick outs, we’re allowing guys to be really efficient. You’d like to see it one way or the other. You’re not going to score all the time early on in the ball games.“We allowed Fried to get in a really good rhythm. … He probably averaged 10, 11 pitches per inning. It was really impressive. Our offense is gonna be fine, we’re gonna come around and we’ll get going.”It’s early, seven games into a season. But it’s late, with only 53 to go.
