With a chance to clinch a playoff spot with a win and some help later in the night, the Orioles instead suffered their most frustrating loss of the season on Saturday.Beyond the obvious effects on the wild-card-standings, the 7-3 defeat to the New York Yankees was even more difficult to stomach because of Buck Showalter’s role in the late-inning collapse. As deserving of the benefit of the doubt as any manager in baseball, Showalter leaving starter Wade Miley in the game to give up the game-tying home run to Tyler Austin to start the bottom of the seventh was baffling.The Baltimore skipper told reporters in the Bronx after the game that he believed Miley was still strong at 99 pitches and that the many left-handed hitters available to come off the New York bench — presumably against right-handed reliever Mychal Givens — prompted him to stick with the lefty starter to begin the seventh. Of course, one could dispute just how strong Miley was at that point after he’d pitched into significant jams in both the fifth and sixth innings in which the Yankees shrunk the Orioles’ lead from 3-0 to 3-2.Miley had given the Orioles a strong performance through six innings, but that should have been all for the starter, especially considering the bullpen hadn’t been particularly taxed in the series-opening 8-1 win on Friday. This was the penultimate game of the regular season, after all, and not a game in mid-June in which you’re thinking about the long-term health of your bullpen.The leash was long enough for that sixth inning, let alone even thinking about having him start the seventh.But Showalter’s overthinking wasn’t the only factor working against the Orioles on Saturday if we’re being fair.Even if Miley had been lifted after six, All-Star setup man Brad Brach was always going to factor into the late-inning equation and the right-hander just didn’t have it on Saturday, giving up four runs, two hits, and two walks while retiring only one batter in the eighth inning. Brach had rebounded nicely in the month of September, but he hasn’t been the same dominant force in the second half of the season, pitching to an underwhelming 3.94 ERA since the All-Star break.It’s no secret that Brach carried an enormous workload with Darren O’Day missing a large portion of the season, and he hasn’t been nearly as consistent in the second half as a result.An offense that plated three runs over the first three innings against Yankees starter Luis Severino all but went to sleep in the final six innings of the game. J.J. Hardy grounded into a 5-4-3 double play with runners on first and second with one out in the sixth, and Manny Machado was inexplicably thrown out at third after Mark Trumbo singled with two outs in the seventh. Those were the only real scoring threats for Baltimore after Machado’s opposite-field solo homer in the third inning.There’s been far too much of that in recent weeks.Even the defense was a question mark.With two outs in the sixth, Machado made a nice stop of a grounder off the bat of Rob Refsnyder, but he took too much time getting up to make the throw to get him at first base to end the inning. Chase Headley then followed with a double to make it a one-run game.There was plenty of blame to go around after Saturday’s loss as the Orioles could only watch what was transpiring in Boston and Atlanta to determine what they needed to do in the final game of the season.It’s tough enough when players simply don’t come through, but seeing a tactician like Showalter blink in such a crucial game was disheartening. It was the kind of decision that disrupted the karma of a game in which the Orioles were winning, but we’ll never know how it might have turned out otherwise. Brach pitching in a similar fashion would have surely netted the same result of a loss.Baltimore just wasn’t good enough on Saturday, whether talking about the players or their revered manager.You can only hope it didn’t cost them dearly.
