What an opening day of the 2015 Big Ten Baseball Tournament.

We had no shortage of highlight-reel plays, including several all-out diving grabs, in Wednesday's first four games at Target Field, home of the Minnesota Twins.

Of all the #BTNStandout-worthy plays, though, Nick Day's dramatic walk-off dinger to help No. 2 Iowa stun No. 7 Ohio State, 3-2, took the day's top moment/play.
