TORONTO – Caleb Joseph didn’t need a large sample size to get a feel for Orioles catcher Adley Rutschman, to properly ascertain just how good baseball’s No. 1 prospect can be behind the plate and with a bat in his hands.

One series was sufficient for Joseph to receive confirmation Monday night as he sat in the Blue Jays’ radio booth to begin a four-game series. It matched the research done to prepare for his assignment.

The next chapter in Joseph’s professional life isn’t as a scout, but he knows catching, having spent parts of seven seasons doing it at the highest level and 555 games catching in the minors. He knows a legit player when he sees one.

And he understands why success doesn’t arrive at the exact moment that the jersey is buttoned for the first time.

Rutschman caught last night and hit his first major league home run, which also produced his first two RBIs – sending a 94 mph fastball from José Berríos over the center field fence in the fourth inning. He’s 3-for-11 in the series, serving as the designated hitter Tuesday with Trey Mancini injured and Anthony Santander back in Baltimore.
