Read full report: 2 offers made for possible MLB stadium sites

UPDATE: The Portland Diamond Project made an unsolicited offer to Portland Public Schools to purchase the district's administrative offices in North Portland for an MLB stadium site.

PPS spokesman Dave Northfield confirmed on Tuesday the offer was made. Northfield issued the following statement:

"The Superintendent met with Portland Diamond Project on two occasions at their request. They introduced the idea of bringing major league baseball to Portland. The Superintendent listened and reiterated our core mission and priorities which focus on improving student outcomes. While PPS is not actively marketing the BESC property for sale, we did receive an unsolicited offer from Trammell Crow Company to purchase the BESC property. The school board has not yet had a group discussion about this offer.

The BESC property is an important and valuable asset, and the Superintendent and Board of Directors take their stewardship of this and other real estate assets very seriously. District leadership has an obligation to ensure that any possible sale of property maximizes the return, in order to better serve our students and fulfill our mission.”

A spokesman for the Portland Diamond Project also confirmed the offer.

PORTLAND, Ore. — Major League Baseball in Portland is one step closer to becoming a reality.

On Monday, KGW confirmed that a group formed last year to bring baseball to Portland is led by a former Nike executive named Craig Cheek.

While there's been talk about the possibility of Major League Baseball in Portland for years, this appears more organized than past efforts.

The group behind this effort even has a name, logo and website .

It's called the Portland Diamond Project.

KGW contributor and Oregonian columnist John Canzano said one possible site for a new baseball stadium is where the current Portland Public School offices in North Portland next to the Moda Center.

But if the city of Portland doesn't play ball, Canzano said the group may look at building the stadium along the river in Milwaukie.

Canzano said if Portland does get a stadium, a Major League Baseball team will likely follow.

"You've got a team in Oakland that doesn't have a stadium plan, that is frustrated, that has nowhere to go ... suddenly Portland, if it has its arms open and a stadium in the process of being constructed, becomes a pretty attractive place for the Portland A's to end up," Canzano said.

On March 31, longtime Bay Area sports columnist Ray Ratto reported that there have been "quiet whispers" that A's owner John Fisher "might offer the team up for sale, with relocation an option."

Ratto mentioned Portland as a potential destination, along with Montreal, Mexico City, Charlotte and Nashville.

Canzano said if a stadium is built in Portland, it would likely be a smaller stadium, around 35,000 seats.

Nothing is a done deal yet, Canzano said, but the group is expected to make an announcement sometime later in the week.

On Sunday, Canzano reported the group had met with city officials to talk about plans to build a stadium in downtown Portland.

"A city hall source confirmed that Portland Mayor Ted Wheeler is in communication with representatives of the group. A second source indicated that the group is engaged in talks to secure two potential stadium sites," Canzano wrote.

Canzano also reported Sunday that the group is planning on using mostly private funds to pay for the stadium, which would quell concerns about asking the city to use public dollars to fund a stadium.

In September, MLB commissioner Rob Manfred said Portland would be on a list of potential cities for league expansion.
