BOSTON – Highlighted by a pair of clutch RBI singles and sophomore Kasey Ricard's 17 combined strikeouts in 13.2 consecutive innings of work, the No. 23 Boston University softball team outlasted Bucknell in back-to-back 1-0 victories Sunday afternoon.

With the doubleheader sweep, the Terriers (40-4, 12-0 PL) surpassed Big 10 member Northwestern (27) to grab the nation's longest active home win streak at 28 games. Graduate student Allison Boaz delivered the walk-off RBI single in the 12-inning game one thriller, and classmate Caitlin Coker grabbed the lead for good in the second contest with her own RBI single in the fifth.

Coming off Saturday's solo shutout, Ricard (21-3) allowed just five hits against two walks to help BU add two more shutouts against the Bison (15-25, 6-9 PL) and move into a tie with defending national champion Oklahoma for the NCAA lead at 21 total.

Coker finished with a double and two singles on the day to set the program record for hits at 266, while senior Kayla Roncin recorded four singles.
