Joondalup looking for improvement
Joondalup will look to recover from its undesirable start to the WA Premier Cricket season when it faces Subiaco Floreat on Saturday.
The Centurions are on the back foot after two losses to open their season, with Fremantle and Gosnells proving far too strong in the one-day clashes on Saturday and Sunday respectively.
Joondalup was without WA rookie Josh Inglis (domestic one-day duty) and Garrick Morgan (injury), subsequently struggling with the bat in their absence.
The Centurions’ Jaron Morgan (39 and 37) tried hard in both fixtures, but his side was rolled for 118 against Fremantle in pursuit of 7-236 at Iluka Sports Complex.
Joondalup’s Michael Johnson (48) top scored against Gosnells at Sutherlands Park to allow the Centurions to reach a competitive 154.
But Gosnells needed just two wickets to chase down the target inside 30 overs.
