On November 5th, 2014 the Los Angeles Angels traded catcher Hank Conger to the Houston Astros in exchange for catcher Carlos Perez and right-handed pitcher Nick Tropeano. Perez did well at first for the Angels winning the starting catching job halfway through the 2015 season, but he never could recapture his early success the next two seasons and was traded just before the 2018 season started.
Tropeano on the other hand has shown some brief periods of success both in 2015 and 2016, but then was lost for half of the 2016 season and the entire 2017 season due to a torn UCL in his pitching elbow which recruited Tommy John Surgery.
