White Sox closer David Robertson worked a two-hit ninth inning, but did not allow a run en route to his third save of the season in Chicago's 5-3 win over the Royals Sunday.

Robertson allowed two singles in the ninth, but his two strikeouts and groundout by Omar Infante was good enough to end the game.

"It probably was an interesting situation for him essentially starting a game," White Sox catcher Tyler Flowers said of Robertson's throwing twice Sunday. "The typical Robertson. Came in, shut them down, gave us a chance in the bottom and on the save right there, he just missed a couple spots and ended up giving up the base hits. But other than that, he went right back to executing pitches."

Robertson is yet to allow a run in his seven innings of work with 14 strikeouts and just one walk.
