After last night's tough loss, my statistical model now gives the #BlueJays a 56.84% chance of prevailing in tonight's seventh game. It'll be tight. Let's go Blue Jays!

With last night's convincing win, my statistical model now gives the #BlueJays an 81.4% chance of winning the World Series. Go Jays Go! :-)

For Maths fans, 2025 is a square.
45² = 45 x 45 = 2025
Also,
9² x 5² = 2025
40² + 20² + 5² = 2025
My favourite?
