The Arizona Diamondbacks are calling up top outfield prospect Alek Thomas to the major leagues, per ESPN’s Jeff Passan.

As Passan stated, ESPN baseball insider Kiley McDaniel has Thomas as the 14th-best prospect in all of baseball. has Thomas at No. 18 in their top-100 prospects list. He’s widely seen as the top prospect in the D-Backs’ system, just ahead of fellow outfield prospect Corbin Carroll.

Thomas was selected right out of high school in the second round of the 2018 MLB Draft. A Chicago native, Thomas slashed .277/.362/.495 with four homers and 14 RBIs in 24 games in Triple-A this season.

The call-up comes in the middle of what has been a surprising start to the season for the Diamondbacks so far. Their 14-14 record has them at .500 just over a month into the season. It was expected to be another rebuilding season, particularly in the challenging NL West. While the rebuild remains the case, they’ve shown the ability to be competitive in the meantime.

Despite the solid start, Arizona’s offense has been interesting case study. Their team average of .191 would shatter the modern-era record of .211 currently held by the 1910 Chicago White Sox. They rank seventh in the MLB in homers though with 31, which has kept them afloat. The offense has been the definition of the “three true outcomes” with their homers, strikeouts, and walks. They have the fifth-most strikeouts (256) and tied-for-second-most walks with 107.

It’s exciting times for Diamondbacks fans, as they seem to finally have something to look forward to. The start of that bright future begins with Alek Thomas’ promotion to the big leagues. Corbin Carroll, your time is next.
