Trent Rockets bagged their second win of The Hundred as they beat Birmingham Phoenix by 11 runs in front of a 10,000 crowd at Edgbaston.
Heather Graham’s unbeaten 44, from 21 balls, lifted the visitors to 145-5 from their allotted time.
The Phoenix's reply fell short at 134 for eight after a top-order collapse to 58 for five left the lower batters with far too much to do.
Nat Sciver conceded just three runs from her first ten balls, Sarah Glenn leaked just 17 from 20 and Graham 15 from 15 while Sammy-Jo Johnson took three for 28 in 20.
"I enjoyed batting out there. As the ball got a little bit older and softer, it got a little bit easier to bat,” said Graham.
“We were probably a little but under par towards the back end so the way myself and Abbey (Freeborn) finished off just got us up to a good total.
"Then they started well with the bat but our bowlers came back really well and used their variations and I think they showed the composure that our team has started to create now.
"We needed that win - that's two wins away from home, now so now we have to do it back at Trent Bridge.
"It was a really good atmosphere. It slowly built from the very first ball and it's something that we don't experience as much in the WBBL as they have moved away from double-headers with the boys.”
After choosing to bat, the Rockets were given a strong start by Johnson. The Aussie moved fluently to 29 (21 balls) and looked set to dominate the innings when she perished in the unluckiest fashion.
Rachel Priest timed a straight drive sweetly and when bowler Abtaha Maqsood deflected the ball on to the stumps, Johnson was stranded out of her ground.
Priest (18 from 15 balls) skied a return catch to Emily Arlott but Nat Sciver (27 from 23) kept the runs ticking over before charging and missing at Kirstie Gordon and falling stumped.
As the Phoenix bowled tightly, the Rockets needed some late impetus at 118 for five from 91 balls and Graham supplied it. The last nine balls yielded 27, including six from the last ball which Graham lifted over long on.
The Phoenix started strongly as Eve Jones and Shafali Verma bashed 29 in 14 balls but both then fell in the space of four balls. Jones chipped Johnson to mid-on where Sciver took a great, low catch running in and then Verma was bowled by Katherine Brunt.
The Rockets followed up with another big blow when Sciver removed home captain Amy Jones, caught at mid-wicket. When Erin Burns and Gwen Davies sent up catches, five wickets had fallen for 29 runs in 34 balls.
That was 58 for five after 48 balls and there was no way back for the Phoenix.
Katie Mack offered some resistance with 24 and Issy Wong hit successive sixes in a merry 11-ball 27 which lifted the crowd but the Rockets ultimately closed the game out.
