Perez has had mixed success since making his debut with the Angels back in 2015. For his career he has a .226/.29./.357 slash line with an OPS+ of 83. However, in his most recent season in the majors with Oakland he had a wRC of -4.
While those numbers don't exactly inspire confidence, catching depth is always at a premium and Perez could find himself the next man up behind the Cubs tandem of Carson Kelly and Miguel Amaya.
Fun fact, there is another Carlos Perez who is a catcher in major league baseball. The other Carlos Perez happens to be this Carlos Perez brother.
Perez the younger, the one who didn't sign with the Cubs, has played a total of 34 games for the Chicago White Sox, spread across two seasons.
