The battle for the title remains intense, with City of Manchester and Polytechnic both winning earlier in the day.
Lancaster proved to be no pushovers in the early stages against Penguin. The London side raced into a 4-0 lead but, when Tom Curwen slotted his second penalty towards the end of the second period, Lancaster trailed only 6-5.
However, it was one-way traffic after that, Penguin scoring six in the third quarter.
Early in the day, Lancaster went down 15-12 to Polytechnic. Poly appeared to be coasting to victory when they led 13-7 early in the final period. But Lancaster's powerful shooting from distance - notably by Scott Sharpe and Tom Curwen - kept them in the hunt as the margin reduced to 13-11, only for late goals by Nick Hock and Giacono Cupido to take Poly clear again.
Manchester defeated Cheltenham 10-7 - a game that was much closer than the final score suggests. Manchester were 6-3 ahead early on, but then faced a determined Cheltenham rally, which reduced Manchester's advantage to 8-7 when George Davies scored early in the final quarter. Cheltenham needed the next goal, but failed to cash in on two man-up chances - and Manchester promptly made it 9-7 through Dan Paddon (Photo: Trevor Hyde). Jordan Elliot's deflected shot added a final Manchester goal at the end of an excellent match.
