April 1st.
He’ll get announced into the game in the 7th inning, with the Cubs losing 7-2. As he warms up on the mound, he feels a pinch in his shoulder. Catcher knows something’s up. Pitching coach and trainer meet him on the mound. He makes the slow walk back to the dugout without actually getting to face any batters.
April fools, can’t believe you guys thought Merryweather was actually going to pitch this season!
