He is 31 and without a contract for next season, but Blake Ferguson showed there's still plenty of life in his legs as he recorded the top speed last weekend.

According to Telstra Tracker data, the Eels winger was clocked at a slick 36km/h in the tough 8-6 semi-final loss to the Panthers.

Ferguson, who has been linked to Japanese rugby, could yet be a handy pick-up for an NRL club with four tries in his last four appearances of the year.

Sea Eagles winger Jason Saab again impressed as he effortlessly zoomed away to score a trademark long-range try against the Roosters, but the 20-year-old only reached a peak of 35.3km/h.

Recalled Panthers outside back Brent Naden (34.7km/h) and Roosters pair Adam Keighran (33.8km/h) and James Tedesco (32.5km/h) completed the top five speedsters in week two of the finals.

Saab led the way for high-speed metres (20km/h or more) as he chalked up 763 with Parramatta captain Clint Gutherson (753hsm) typically giving his all against Penrith.

Some questioned Eels coach Brad Arthur's decision not to start Ryan Matterson, but the forward gave everything he had in a 42-minute stint off the bench, averaging 101.1 metres per minute.

Roosters hooker Ben Marschke (99.8m/min) ranked next in a solid performance considering his relatively limited match fitness.

When it came to total distance, Panthers playmaker Nathan Cleary (9.4km) edged out Parramatta No.7 Mitch Moses (9.2km).

Usually, halves, fullbacks and the occasional hooker fill out the top five, but Penrith centre Paul Momirovski (9.05km) and Manly winger Reuben Garrick (9.03km) flew the flag for outside backs last weekend.
