However, the visitors immediately attacked again, overwhelming the Hammers for a third time in the process to complete a miserable opening half. Tysiak’s miscued clearance fell kindly to Beever-Jones in the box, who rifled into the far corner from distance past a static Szemik.
And before referee Amy Fearn blew for half-time, it was so close to being four. Ramírez sent in a cross from the right channel, which saw Baltimore unleash an effort goalwards, only to be denied by another full-stretch Szemik save.
Shekiera Martinez was sent on for her West Ham debut from the bench at the break, but Chelsea continued in a similar vein after the restart, with Baltimore adding a fourth to effectively end the contest seven minutes after the restart.
Niamh Charles robbed West Ham of possession in the final third, and the ball fell to Baltimore, who set herself and powered a left-footed strike that Szemik could not keep out.
Skinner’s side, to their credit, never gave up in their attempt to reduce the arrears. Moving on to Katrina Gorry’s through ball, Riko Ueki raced through the left-hand channel before cutting inside a defender to send a blistering right-footed drive towards goal that was saved by Hannah Hampton.
Substitute Oriane Jean-François then hit the side-netting from close range before Ashley Lawrence and Maika Hamano were both brilliantly denied by our No1.
As the game headed towards its conclusion, an unfortunate own-goal from Tysiak completed the rout, by turning Cuthbert’s right-wing cross into her own net, but we did manage to avoid suffering any further wounds on a very painful afternoon in east London.
