After what seems like every Dallas Keuchel start this season, Astros manager A.J. Hinch has been asked about last year’s American League Cy Young Award winner and his 2016 struggles.And after each inquiry, Hinch has delivered the same message.Keuchel doesn’t have to be the 2015 AL Cy Young winner or the stopper. He just need to do his part in helping the Astros turn around what is now a subpar quarter of the season.The lefty was a little of both Tuesday.There was the ace – Keuchel retired the first 11 batters he faced in dominant fashion. And there was the pitcher who hasn’t won a start since April 15 – Keuchel allowed four two-out hits in the fifth and walked the bases loaded before coming out in the seventh.He’ll have to wait another turn to get his third win. Keuchel left the game with the score tied and watched the Astros blow a ninth-inning lead before Evan Gattis gave them a 6-5 win over the White Sox at U.S. Cellular Field in his return.Gattis, who spent 10 days at Class AA Corpus Christi to work on his catching, scored the game’s first run and later sent an 0-2 sinker from former Astros reliever and Clements product Matt Albers into the White Sox’s bullpen in the 11th to win it. It scored George Springer, who reached on a single.The White Sox got one back, but Tony Sipp ended it, striking out Alex Avila with the tying run standing on second base.The Astros had earlier chances, which included going up in the eighth inning. Jose Altuve, after not reaching in his first two at-bats, gave them a 4-3 lead with a sacrifice fly.Before that, it was Tyler White, who started the eighth-inning rally with a double but also homered twice for his first 3-hit game since the opening week of the year.He snapped his homerless streak that dated back to April 20. The first put the Astros up and the second tied the game, taking Keuchel off the hook and erasing missed opportunities – the Astros twice left the bases loaded.It didn’t stick.After Ken Giles struck out consecutive batters to end the seventh and Will Harris worked a 1-2-3 eighth, the White Sox got to Luke Gregerson in the ninth.Austin Jackson led off with a double and went to third on a Carlos Sanchez bunt. Tyler Saladino followed, lifting an 0-1 slider to center for the game-tying sacrifice fly.It was Gregerson’s third blown save in four chances after converting 16 consecutive opportunities.It was also another missed chance for the Astros, who led early.
