Seattle's Andrés Muñoz threw a 103 mph strike that had everyone, including Vlad Guerrero Jr., in awe

The Seattle Mariners haven’t been in the playoffs since 2001 but they looked right at home in Game 1 of their wild-card series with the Blue Jays on Friday afternoon, winning 4-0 in Toronto to take a 1-0 series lead.

The Mariners pitchers – starter Luis Castillo and reliever Andrés Muñoz – were so good all day long and showed why this Seattle team could be a lot of trouble in the playoffs.

Munoz pitched the eighth and ninth innings to get the save and the dude was throwing pure gas for his entire outing. This 103 mph pitch that he threw for a strike against Vlad Guerrero Jr. was just ridiculous.

Love the head nod there from Vlad. He knew how good that pitch was.

Oh, and that was just the fastest pitch we’ve seen in the playoffs in five years:
