So that’s what Robin Ventura had in mind when he asked for the White Sox to wear their big-boy pants. Well for starters, anyway. Jose Quintana’s offense got him some early runs and he did the rest as the White Sox snapped a five-game losing streak by edging past the Baltimore Orioles 4-2 at Oriole Park at Camden Yards on Tuesday night. Quintana allowed a run and six hits over seven sharp innings and the White Sox won for the first time in six games on their 11-game road trip. A night after he surrendered a game-winning home run, Ronald Belisario earned his eighth save after he allowed the tying run to reach base. “After the last five days, you need that,” Ventura said. “It was a good effort by Q to get us in a spot to win. We did enough to win.” Just enough. But after five games in which they made just enough mistakes to beat themselves and dropped to a season-worst seven games below .500, the White Sox will take it anyway they can. Quintana was the driving force in the victory as he made a series of big pitches late in the game his manager approved of. The biggest came in the sixth and seventh innings after the Orioles offense finally got going.
