VIDEO: Eric Hosmer is impressed with Marcus Stroman's slider

As Kansas City Royals starter Aaron Brooks floundered in his first big league start on Saturday, another youngster on the mound in Toronto was featuring some impressive stuff. 

Also making his first-career start, 23-year-old Marcus Stroman allowed one run on five hits while striking out six in six innings of work. 

Among those to go down swinging was first baseman Eric Hosmer, who gave Stroman's slider a "wow" of approval.
