White Sox score eight runs in fifth inning but lose on walk-off walk

SEATTLE — Jose Ruiz (2-2) walked Tom Murphy with the bases loaded in the ninth inning, and the Mariners rallied from a five-run deficit — after blowing a five-run lead — to edge the White Sox 11-10 on Sunday.

With the Sox leading 10-5 in the eighth, the Mariners tied the score on an RBI single by Kyle Seager, a three-run home run by top prospect Kyle Lewis and an RBI single by Mallex Smith. It was Lewis’ fourth round-tripper in six major-league games.

After Austin Adams (2-2) struck out the side in the Sox’ ninth, Austin Nola started the Mariners’ winning rally with an infield single, one of his four hits. He took third on a one-out single by Lewis before an intentional walk to Dee Gordon loaded the bases. Murphy then drew the winning walk. The Mariners matched their season high with 11 walks.

‘‘[We had] a lot of walks today . . . a lot of leadoff walks,’’ Sox manager Rick Renteria said. ‘‘Those are things that we have to certainly clean up in general. You see what happens on a major-league field. It’s not easy to win on a daily basis, no matter who you’re playing.’’

The Mariners batted around twice, scoring five runs in the fourth and eighth. The Sox, meanwhile, scored eight runs in the fifth — their season high for an inning — highlighted by the third career grand slam by Welington Castillo and a three-run shot by Adam Engel. Castillo finished with a career-high five RBI.

‘‘We thought that we put ourselves in a good position,’’ Renteria said. ‘‘[We] got five runs ahead, we tried to get some of these guys to go ahead and finish the ballgame.’’

Before the game, Major League Baseball expressed its regret about a miscommunication that resulted in the Sox’ 2-1 loss Saturday.

The Mariners’ Omar Narvaez hit a ball off the top of the wall in the 10th that umpires ruled a homer. But the ball didn’t clear the fence, and Narvaez would have been awarded a double had a replay review been conducted.

‘‘In last night’s game, there was conversation between the umpires and the White Sox as to the procedure for potentially reviewing two different aspects of the game-ending play,’’ MLB said in a statement. ‘‘There was then a misinterpretation regarding Chicago’s desire to have any aspect of the play reviewed. We regret that this miscommunication resulted in not reviewing the home-run call on the field.’’

Renteria said he immediately asked umpires to review the homer, and they went to the headset used to communicate with replay officials. When Renteria and the umpires reconvened, the umpires asked if Renteria wanted to challenge whether Narvaez had touched home plate amid his celebrating teammates. Renteria mistakenly thought that meant officials had ruled the ball cleared the fence and declined to challenge whether Narvaez had touched home because he had seen replays indicating he had.

Renteria agreed there was a ‘‘miscommunication or misunderstanding.’’
