<p>TJ Montgomery is a lifelong Yankees fan, so it gave him great joy to be at Yankee Stadium last September when the team clinched a spot in the playoffs.</p><p>Not because the Yankees won, mind you, but because a home run by his son, White Sox shortstop Colson Montgomery — with dad, mom Lisa and high school coach Gene Mattingly all there to see it — almost spoiled the Yankees’ celebration.</p><p>“Colson kind of ruined their parade for one or two innings when he hit that home run,” the elder Montgomery said of his son’s two-run shot that night. “I tell people that the coolest home run I’ve seen him hit ever was that night in Yankee Stadium, 40-some-odd-thousand people there. It goes from 45,000 people cheering to just about 100 White Sox fans cheering, you know, from the family section.”</p><p>TJ Montgomery lives in Holland, an itty-bitty town in southwest Indiana (population 600 and change) where the Sox found Colson, their No, 1 draft choice in 2021.</p><p>“Me and him, we were the biggest Yankees fans growing up,” TJ said by phone the other day while taking a break from the roofing work he does for a living.
