Stassi was once again a September call-up for the Astros, making it four years in a row. Although Stassi hit well in his extremely limited big league action from 2013-2015, he got just one hit in 13 at-bats in 2016 after hitting .230 with seven home runs for Triple-A Fresno. While he flashed average power at lower levels, Stassi has averaged just 10 home runs while walking at a rate of well under 10 percent the last three years. He's never hit above .280 in any full season, and at just 5-foot-10 and 190 pounds, there's little to suggest the potential for major improvements in the power department. Jason Castro is gone, but the Astros traded for 32-year-old catcher Brian McCann in the offseason as a replacement. It's clear the Astros don't think much of Stassi's chances to become a viable starting catcher.

Stassi, who has been a September callup for the Astros each of the past three seasons, hit .211/.279/.384 with 13 home runs and 43 RBI over 84 games for Triple-A Fresno last season. It was the fourth time he's posted 13 or more homers during a season in the minors, but it also marked the second consecutive season in which he posted an OBP below .300. Hank Conger was traded to Tampa Bay in the offseason, creating an opening for the backup job behind Jason Castro, Stassi has shown little to suggest he's worthy of anything more than sporadic opportunities.

The Astros have a logjam at the catcher position and Stassi currently has the least big league experience of the backstops on their 40-man roster. Known for his bat as opposed to his arm and defense behind the plate, the soon-to-be 24-year-old struggled last season for Triple-A Oklahoma City, hitting .247/.296/.378 with nine home runs and 45 RBI in 101 games. While it was his first full season with fewer than 13 long balls, Stassi remained healthy for the most part, logging 425 plate appearances. It's possible that he'll repeat Triple-A again, but his future in Houston is currently undecided. His clearest path at playing time would likely come as the backup to Hank Conger if Jason Castro is traded. Then again, Stassi could be a trade candidate himself if the Astros choose experience over youth and upside.

Stassi, a right-handed hitting catcher known for his excellent bat and average defense behind the plate, put together a fine offensive campaign for Double-A Corpus Christi after undergoing sports hernia surgery last offseason. In 76 games, the soon-to-be 23-year-old slashed .277/.333/.529 with 17 home runs and 60 RBI before an injury to Astros backup catcher, Carlos Corporan, opened the door for him in Houston. Stassi's time in the majors was short-lived, however, after he was forced to the disabled list with a concussion. Stassi has been hampered by a number of injuries throughout his career, but if he can stay healthy and keep hitting like he has in the minors, he could easily overtake Corporan as the backup behind Jason Castro. He will most likely return to Triple-A for the start of the 2014 campaign, but there's a good chance he will spend more time in Houston next season.

The A's selected Stassi in the fourth round of the June draft, but he's considered to be first-round talent and signability concerns led to his slide down the draft board. The track record for high school catchers isn't great, and we won't have a feel for Stassi's pro prospects for several more seasons, but the scouting report on him is pretty favorable.
