BALTIMORE — The Rays would have been better off if it rained Saturday. Poured actually.Instead the forecast was off. And so was their play.The result was another frustrating loss, their third in less than a week, to one of the worst teams in the league, 3-0 to the Orioles this time.A good dousing would have washed away Yonny Chirinos’ shaky start to what ended up a solid career-high 71/3-inning outing after the Rays (21-12) abandoned plans to use an opener, allowing runs in three of the first four innings.They wouldn’t have been on the wrong side of Baltimore starter Dylan Bundy’s first win of this season and best start since June, allowing just three hits, and none over a span that included seven innings, while working into the eighth.And they would have been no need to try to explain Willy Adames’ confounding baserunning mistake that took them out of the one rally they seemed to have going in the eighth.“It seems like every time we’re in here at some point we’re trying to play weatherman,’’ manager Kevin Cash joked, kind of, before the game. “I don’t know if we ever get it right.’’Expecting heavy rains to interrupt or potentially cut short the game, the Rays decided about two hours ahead of the first pitch to have Chirinos start rather than work behind scheduled opener Ryne Stanek.Chirinos said it was no big deal or major adjustment, that in his hybrid role, “I’ve got to prepare for anything on this team.’’He did not look particularly comfortable or overly sharp from the start. He gave up a double and a single to begin the first, which led to the first run, but kept them to one. He gave up singles to the Nos. 8 and 9 hitters to open the third, which resulted in the second run, but also limited the damage. The third came on a two-seam fastball he left up that Dwight Smith Jr. hit out to start the fourth.“I thought he was awesome,’’ Cash said. “We’ll take that outing any day of the week from a starter — seven innings and gave us a chance to win. Their guy was just a little bit better. But couldn’t have been more impressed with the way Yonny threw the ball.’’Bundy was dazzling, an unexpected outing from a guy who came in 0-4, 6.67 in six starts, having allowed 46 baserunners in 28 1/3 innings, including nine homers.He gave up a leadoff single to Brandon Lowe in the first, a double to Avisail Garcia to open the second, and … and … and … nothing else until Michael Perez doubled with one out in the eighth. “We do have some guys quiet at the plate,’’ Cash said, “but I do think you’ve got to give the bulk if not all of the credit to Dylan Bundy and the way he threw against us.’’The double ended Bundy’s night, brought Shawn Armstrong out of the bullpen and set up Adames’ mistake and apparent misunderstanding of the rules.What happened was that Adames reached for a pitch and in hitting a slow bouncer toward the mound ran across and stayed on the infield grass as he headed toward first.What looked like a break for the Rays, with Armstrong’s throw sailing over first baseman Chris Davis’s head, Perez scoring and Adames advancing to second, ended up being a mirage.Adames was called out — correctly — for interference, Perez was sent back to second and the rally died when Brandon Lowe struck out.“It was just unfortunate it cost us,’’ said Cash, who went out to get an explanation from the umps but couldn’t put up much of a fight as they were right. “We didn’t have much momentum, but that might’ve been it and it just got taken away from us.’’Adames said, and Cash agreed, that there wasn’t much he could do, that his momentum carried him onto the grass.But his mistake was not correcting his course and getting within the baseline on the way. And, maybe worse, in not knowing that he needed to.“I feel like every righty that has that weak swing runs in the grass,’’ Adames said. “I didn’t know that you have to be like halfway into that box they have marked there. I didn’t know that we couldn’t run through the grass. That’s something new that I learned today.’’Cash said the rule gets talked about a lot, but not changed.“You could sit down with umpires and managers and that rule could be debated back and forth, but they did get it right. It’s the right call,'' he said. "I don’t think anybody really likes it when it happens to them but it’s one of those, it’s a judgement call. I saw where Willy was. He was out of the baseline.’’But Cash also felt Adames wasn’t to blame.“I think when you swing the bat, he kind of hit a chopper, his momentum took him out in front of home plate,’’ Cash said. “It’s tough to say, Okay, now I’m going to reset and get right back in the baseline. That’s the part of the rule that I don’t think the players like. Or, tonight, me.’’It was just that kind of night.Contact Marc Topkin at email@example.com. Follow @TBTimes_Rays.
