Shahzad sees Yorkshire over the line
Yorkshire made heavy weather of it at Headingley as they got their Twenty20 campaign off to a winning start.
Chasing Leicestershire's 148-3, they looked on course at 110-2, only to lose five wickets for 15 runs, including Michael Vaughan for 35.
But young Ajmal Shahzad and keeper Simon Guy saw their side home to win with just one ball to spare.
Ackerman was the Foxes' top scorer, batting through for an unbeaten 66 (from 56 balls) out of their 148-3.
Yorkshire now turn their attention to Tuesday evening's Roses battle with Lancashire at Old Trafford.
