CITY could have no complaints about the final outcome of this match - despite being the victims of some decidedly harsh calls from referee Jon Moss.
Boston deserved the three points and should have been ahead long before Jamie Stevens, 18, headed the only goal of the game.
The most contentious moment of the match arrived on 17 minutes when Mark Greaves' header hit Kevin Sandwith in the chest and appeared to roll onto his arm.
There seemed to be no intent on Sandwith's part but Moss awarded a penalty and dismissed the former Macclesfield skipper. Jamie Clark stepped up to take the spot kick, but Chester keeper John Danby saved it.
On 70 minutes, the Blues felt they should have had a penalty of their own as Colin Cryan tripped Paul Rutherford. But it was not given and Stevens then headed Boston's winner - from a corner Chester's players were convinced should have been a goal kick. Star man: Dave Artell.
