Clinton Lewis couldn't put a foot wrong for Clyst Hydon in their 64-run win over Alphington.
Lewis made 103 in Clyst Hydon's total of 231 for seven, sharing a stand of 163 for the fifth wicket with Graham Trude (72).
Alphington were 121 for five on the chase and reasonably well placed, with Dave Haysom in and out for 33, and Dinesh Raheja on his way to an unbeaten 67.
However, Raheja suffered from a lack of support as no one made double figures after the fifth wicket as Alphington slid to 167 all out.
There were two wickets each for Dhanuja Nandana and Chris Holmes, but man-of-the-match Lewis took four for 27.
Clyst wind up the season with the short trip to Ottery St Mary this Saturday.
Ottery defeated Chagford by three wickets last time out.
Chagford were kept to 178 for eight in their 45 overs, with two wickets each for Rob Crabbe and Billy Reed.
Ottery started well with Read (31) and Crabbe (36) among the runs.
Then following a wobble an unbroken stand of 61 between Sam Lynch (46no) and Mat Reed (26no) ended any doubts about the outcome.
Delighted Ottery skipper Townsend, said: "The guys bowled really well to keep Chagford to 178, which we always felt was very getable.
"We did make hard work of getting there, but we've got a long batting line up so it was good to see the lower order get us over the line."South Devon are heading a for a title decider against Ipplepen this Saturday after a remarkable win over Dartington & Totnes.
