At this point of the season (in a playoff race) if the Jays were to sit Vladdy in favour of an unproven rookie, they would be the laughing stock of the league. It ain't gonna happen so you may as well get that idea out your head.
Interesting what Siddal said about Jansen needing to keep his non glove hand free. Notice Kirk, even with runners on keeps his free hand behind his leg with the pitch incoming.
