Boston Red Sox catcher Danny Jansen is set to make MLB history by becoming the first player to appear in the same game for both teams when the suspended game against the Toronto Blue Jays resumes on Monday. The original game, which took place on June 26, was interrupted due to rain with Jansen at bat and Reece McGuire catching for Boston. Following a trade on July 27, Jansen joined the Red Sox and will take over as catcher for the resumed game, while the Blue Jays will use a pinch-hitter in his place. This unique situation arises from Jansen's history with the Blue Jays, where he spent seven seasons before being traded. Red Sox manager Alex Cora confirmed Jansen's participation, highlighting the significance of this unprecedented event in MLB history. Jansen's performance with the Red Sox has been solid, contributing to the team's efforts since the trade.
