It wasn’t the sharpest pitching performance by Oakdale’s Shelby Reali, but when the going got tough she and the rest of the Mustangs clutched up in big moments during their 1-0 win at Sierra Monday.Reali, who issued five walks but struck out 11 in a two-hitter, was able to pitch herself out of jams while also getting bailed out by her always-reliable defense. Offensively, the Mustangs (10-1, 19-2-1 overall) scratched across an unearned run in the second inning and held on to maintain their lead in the Valley Oak League standings.Sierra (9-3, 12-4-1) drops to third place with its second 1-0 defeat to Oakdale.“I knew that no matter what happened my defense would be there to back me up,” Reali said. “They were making the plays, and I know they have the confidence in me to make the pitches.”Opposite Reali was cannon-armed Allison Walljasper, the 2011 MVP of the league.
