If you’ve followed @KUBaseball at all this year, you’ve heard a bunch of people describe them as a special group. Stats are great. Season’s been incredible. But it’s this image, from Thurs night in Arlington, that best illustrates why so many said that… r1s1sports.com/a-picture-wort…

In just his 31st at-bat of the season, @mikekoszewski came through with a walk-off RBI single, helping @KUBaseball advance to the @Big12Conference tournament semifinals. @Stitch_Head recaps all the action on Day 2 at @GlobeLifeField ⤵️

In case you didn’t know… @KUBaseball wins A LOT 🔥 #RockChalk
