Canberra Cavalry MVP Jay Baum came here hoping to make someone take notice and then he posted numbers that means someone in Major League Baseball surely must.

While there's been no contact from any MLB clubs as yet, Baum's batting average was astronomical from his stint in the Australian Baseball League.

He has a league-leading batting average of .439 and if he can maintain it it will be an ABL record.

Not surprisingly, Baum was named the Cavalry most valuable player on Monday night.

But his focus was on helping the Cavalry get past rivals Perth Heat in the ABL semi-finals in Perth, with the three-game series starting Friday to decide who will make the championship series in a week's time.

After four years in the MLB system, the Seattle Mariners released the 25-year-old last year.

He finished the USA summer playing in the independent Canadian-American Association for Sussex County before he joined the Cavalry.

Since then he's been lighting up ballparks around Australia with a hot streak that's lasted the entire regular season.

Cavalry manager Michael Collins hoped Baum would "get another chance" with an affiliated club, but Baum was yet to get a call.

Baum revealed waiting was a tough part of the business.

"Not yet, I'm hoping I get a call or something soon, but definitely that's my goal. That's why I came out here," Baum said.

"I think I've shown that I can play.

"It's tough in terms of a lot of it eing out of your control ... hopefully at the end of the [season] when I get back to the States I hopefully receive a call."

The Cavalry have a proven record of getting players back into MLB-affiliated baseball.

Adam Buschini had a fantastic 2012-13 ABL season and was picked up by the San Diego Padres and the Arizona Diamondbacks signed Ryan Stovall for his efforts in that same championship-winning season.

Baum's had a better season than both of them.

He grew up playing baseball and ice hockey. The baseball was from his father's side - who also played golf at college - while his mother played ice hockey at college.

While he wanted to do well, Baum didn't think he'd do as well as he has.

"I wasn't expecting that, but I just came out here to show I could play well and then everyone on the team's been playing so well - hitting's contagious - it just kept me positive and I kept playing well throughout the year," Baum said.

"I've never had numbers like that. I've definitely been working on every game here on staying with my approach and being consistent with that.

"Which I think I've done much better this year than I have any of the past years playing professionally."

The Atlanta native said they were confident heading into the Heat series.

Canberra will face a weakened Heat, who have lost two of their star hitters.

Michael Brosseau had a batting average of .427 before the Tampa Bay Rays recalled him to the USA, while ABL leading run scorer (50) and base stealer (39) Jake Fraley has also returned home.

Brian Grening will start game one on Friday night, while Lake Bachar will start game two on Saturday, with the Cavalry's other starters, Frank Gailey and Steve Kent, adding depth to the bullpen or starting game three if required.
