Andrew Flintoff took two wickets on his return to competitive cricket as Lancashire beat Worcestershire by 50 runs to move top of the NatWest T20 Blast North Division.
The former England all-rounder was listed to bat at number eight and was not required as his side piled up 229 for four at New Road. Ashwell Prince top-scored with 68 while the main aggressors were Jos Buttler, who made 55 off 28 balls, and Steven Croft with 29 from 11.
Croft removed Pears openers Daryl Mitchell (46) and Richard Oliver (44) after a 90-run stand and Flintoff, having seen his first seven balls disappear for 21 runs, recovered to post figures of two for 36 in his four overs as the hosts were restricted to 179 for seven.
Tom Kohler-Cadmore and Alexei Kervezee were the 36-year-old's victims in his first game for almost five years. Croft and Kabir Ali each took two for 30.
Elsewhere in the North Division, Leicestershire recorded only their third win of the season and inflicted Derbyshire's eighth loss in 10 games.
Derbyshire made 143 after a remarkable end to their innings. Charlie Shreck began the final over but was removed from the attack for bowling his second beamer of the innings. Anthony Ireland took over for the remaining five balls - and took three wickets, completing figures of five for 22, before Mark Turner was run out from the last ball.
Wes Durston's brilliant 89 was a lone effort, with Marcus North's 20 the only other score in double figures, and it was not enough as Greg Smith made 65 not out to guide Leicestershire home with four balls and five wickets to spare.
In the South Division, Somerset brushed Hampshire aside by 39 runs after bowling them out for 116 - Alfonso Thomas, Dirk Nannes and Peter Trego with two wickets each.
Craig Kieswetter (60) and Alviro Petersen (38no) earlier led the west country side to 155 for four.
