UNCASVILLE, Conn. (AP) _ Swin Cash scored 17 of her 20 points in the first half to lead the Detroit Shock to a 78-61 victory over the Connecticut Sun on Tuesday night.

Center Ruth Riley and Kedra Holland-Corn each added 13 points and rookie forward Cheryl Ford grabbed 12 boards for Detroit (19-6), which extended its winning streak to five games and tightened its grip on first place in the Eastern Conference.

The Shock led by as many as 21 points and were up 47-28 at halftime, scoring easily and often in transition. The 19-point halftime deficit was the largest for Connecticut (14-13) this season.

Katie Douglas led the Sun with 14 points and six rebounds, while Nykesha Sales and Taj McWilliams-Franklin each scored 11 points.

The Sun struggled from the field and couldn't keep pace with Detroit's speedy transition game and inside power.

Detroit's dominant inside trio of Cash, Riley and Ford clogged up the middle, giving Connecticut little room to work. Detroit outscored Connecticut 50-30 in the paint and finished with 38-27 edge on the boards.

Connecticut, 0-4 against Detroit this season, found the going just as futile early from the outside, hitting 1-of-12 from behind the arc in the first half.

The Shock extended their lead to 23 points in the second half. The Sun mounted a small rally on three straight 3-pointers by Douglas, but would get no closer than 13 points.
