CHICAGO -- A foul ball turned into a tiebreaking RBI single and the decisive run, leaving the Chicago White Sox thanking Omar Narvaez and instant replay.Narvaez came through in his fifth major league game after the replay challenge, and the White Sox beat Chris Tillman and the Baltimore Orioles 4-2 Saturday night.Its what replay was meant to do, White Sox manager Robin Ventura said.With the bases loaded and nobody out, Narvaez hit a popup to shallow left field off Mychal Givens. Third baseman Manny Machado tried to make an over-the-shoulder catch, but the ball dropped and umpire Mike Winters immediately ruled it foul.I think the umpire got blocked out a little bit by Machado, White Sox center fielder Adam Eaton said.Replays showed the ball hit the foul line . The question was if it hit Machados glove first and, if so, was his glove in fair or foul territory.Orioles manager Buck Showalter said the ball hit Machados glove.Doesnt matter where it hit the ground if it hit his glove, Showalter said. So, Im hoping they felt like they had a replay that was definitive enough that he touched it in fair territory, because we dont have one. Maybe theyve got one.It was ruled fair and pinch-runner J.B. Shuck was awarded home. Narvaez got a single and has hit safely in each of his first five big league games.Hes come up here out of necessity, but hes jumped up pretty quick through our system, Ventura said. His at-bats are the thing that are starting to impress everybody.Eaton added an eighth-inning solo home run, Nate Jones (5-2) got four outs and David Robertson worked around a walk the ninth for his 27th save.Tillman (14-4) allowed two singles to lead off the seventh before he was lifted, failing in his third try to get his 15th win.Not good. Not bad, said Tillman, charged with three runs and seven hits. Made a lot of good pitches when we needed to. A lot of hard contact, a lot of hard outs, both in the air and on the ground.Tyler Saldino also homered and Melky Cabrera added an RBI double for the White Sox, who won for the third time in 10 games.J.J. Hardy drove in both runs for the Orioles, who stayed percentage points ahead of Toronto atop the AL East.The White Sox went up 1-0 on consecutive doubles by Tim Anderson and Cabrera leading off the first. Saladinos liner to left on an 0-1 changeup in the third made it 2-0 as Tillman struggled with his command.The Orioles were unlucky in
