What happened: William Contreras threw out Victor Mesa Jr. trying to steal third base for the final out of the inning in the World Series.

Why it matters: The caught stealing ended the threat while Jacob Misiorowski was pitching in traffic, with the Brewers protecting their pitcher at a key point. It was a costly baserunning risk for Mesa Jr., one of the acquisitions Tampa Bay has leaned on this October. Contreras had already made an impact in the series with an RBI single in the first inning of the opener.

What to watch: Watch whether Tampa Bay keeps testing Contreras's arm on the bases for the rest of the series.
