Despite an unbeaten century from David Wainwright and a half century by James Sykes, Castleford fell short in their run chase at Sheriff Hutton Bridge in the Yorkshire Premier League North.
Set 263 to win, they knew they would be up against it from the start, particularly then as openers George Swaby and Connor Hyde were both out without scoring.
But Mohammad Waqas began a recovery as he hit a six and four fours in a 31-ball knock of 27.
Skipper Wainwright and Sykes then came together and put on 115 for the fourth wicket, taking the score up to 150 before Sykes was caught out having made 52, including six boundaries.
The remaining batsmen struggled to support Wainwright and Cas found themselves too far behind the asking rate to force a victory.
They did bat out their full 50 overs, however, ending on 211-7 with Wainwright finishing not out on exactly 100 after cracking 11 fours in his battling knock.
Mark Fisher, with 3-45, was the pick of the bowlers for third-placed Sheriff Hutton, who had earlier made 262-7 in their 50 overs with Fisher again leading the way in hitting 117.
Eddie Morrison did his best to restrict the hosts as he took 4-62 in 14 overs while Connor Hyde claimed 2-55.
Castleford seconds gave the club something to cheer about as they beat Londesborough Park II by 90 runs in the York League’s Ebor Division Three to boost their hopes of avoiding relegation.
Batting first, they were able to set a challenging target in making 218 as Ardash Vani and Nathan Smith both top scored with 59 and there were handy runs also from Eddy Cole (37), Darren Hyde (16) and Amol Vani (13).
Londesborough Park were then all out for 128 with Smith following up his batting exploits by taking 3-23.
George Gibson mopped up the lower order with 4-25 while Ardash Vani took 2-29 and Darren Hyde 1-11.
Castleford under 11s were well beaten by Pledwick in the Pontefract Junior League.
After Pledwick made 122-1 in their 20 overs, with Charlie Goose taking the only wicket, Cas were all out for 29 in reply, Isack Newrick top scoring with five.
