Boston Red Sox top-30 prospect rankings after the 2019 season

1. Triston Casas (First Baseman)

Could the number one prospect in the system have been anyone else? Triston Casas was the Red Sox first round pick in 2018. In his first season in the organization, Casas slashed .256/.350/.480 between Full-A and Advanced-A.

The left-handed hitter was 19 years old for the entire 2019 season. Seriously, he was born in the 2000s and now I feel old.

Casas played almost the entire season in Full-A. With the Greenville Drive, he hit .254 with 25 doubles, five triples and 19 home runs. He drove in 78 runs, scored 64 more and stole three bases.

Meanwhile, he played two games in Advanced-A, going 3-for-7 (.429) with a double and a home run. He also three RBI and two more runs scored.

For those keeping track, That’s 26 doubles, five triples, and 20 home runs. That’s also 81 RBI and 66 runs scored.

Casas also got a chance in the playoffs this year. He didn’t disappoint. In five games, he went 5-for-19 (.263) with a double, two walks, one run scored and one RBI.

This will be what makes Casas a superstar prospect. Talk about elite hitting potential.

What I love to bring up is his approach at the plate. Casas has plus-plus power potential. I’m talking 30-plus homers easy. But he chokes up on the bat pretty significantly. This gives his already promising contact potential higher.

This is someone that can hit around .300 while being one of the best power bats around. There really is no serious weakness in his game at the plate.

Meanwhile, Casas started his career as a third baseman. He has played just nine games at the position in his career so far though, and they were all in 2018. In 2019, he played all 96 of his games in the field at first base.

While he’s not a gold glover yet, Casas definitely took to first base well. At 6’4″, 238 lbs he has a great frame for the position. He’s also surprising nimble (which probably shouldn’t be that surprising because he played third but still).

Casas continuously improved as the year went on. He could be a plus-fielder with legitimate gold glove potential as time goes on.

Once that happens, Casas will be the full package. He’s already dangerously close to that.

Not only is Triston Casas the best prospect in the Boston Red Sox system, he’s one of the best in the world.
