A busy forward who was a slippery customer and always dangerous around goal, Lockwood was said to be a level headed player, but in 1901 he and his twin brother were dropped from the Geelong side because of irregular attendance at training.

In 1902, while playing for Collingwood, he was said to have played a better game against his old club than he ever had for it.

With 35 goals he topped the League goalkicking in 1903 and was a member of the premiership side for the second successive year.

He represented Victoria in 1902.
