Trainer Darren Weir has edged closer to 300 winners for the season and has a four days left to reach the milestone.

Weir-trained runners have been successful in 297 races this season Australia-wide and the trainer has four runners entered at Pakenham on Tuesday.

The trainer prepared a winning double at Swan Hill on Monday courtesy of Stellar Collision and Pantuo which moved him closer to the 300 mark.

Weir also has four runners accepted for the Cranbourne meeting on Wednesday while he will have horses at Sale on Thursday and Pakenham on Friday, the final day of the season.

Last weekend Weir clinched his second-straight Victorian metropolitan trainers' premiership with a winning double at Caulfield and added another double at Geelong on Sunday.

He finished the metropolitan season in Victoria with 79 wins, seven ahead of closest rival Peter Moody.

Weir has prepared a total of 101 metropolitan winners nationwide including 22 in Adelaide where he had a treble last Saturday.

Chris Waller has trained the most metropolitan wins for the season with 182 and is well represented at the final Sydney city meeting of the season on Wednesday at Canterbury.

Weir's previous personal best number of winners was 253 last season when he won his first Melbourne trainers' premiership.
