Right: St. Lucy’s all everything Danielle O’Toole…

Tuesday’s Sierra League results: Chino Hills beat Charter Oak 5-3 to stay in the Sierra league lead, improving to 18-5 and 9-2. South Hills outslugged Claremont 9-5 to stay a half-game back of first, improving to 15-6 and 9-3 in league. St. Lucy’s pitcher Danielle O’Toole threw a one-hit shutout with six strikeouts for the Regents, who earned an much-needed 2-0 win over Ayala to move into a tie for third with the Bulldogs, who both sport identical 6-6 league records. All of these teams meet again on Thursday, St. Lucy’s needing to win again to move into third all alone. Meanwhile, Chino Hills and South Hills are still in a tight race for the title — neither can afford to stumble with three games left.
