Washington Nationals outfielder Adam Eaton took to Instagram on Monday to react to his former teammate and Los Angeles Angels pitcher Tyler Skaggs death with an image of an old poster that dubbed Eaton and Skaggs as Arizona's "2013 Rookie Stars."

The Angels drafted Skaggs with a compensation pick in 2009, a year before the Diamondbacks took Eaton with in the 19th round. But Arizona ended up signing Skaggs later in 2009, and a few years later the pair ended up in High-A Visalia together. That year, 2011, Eaton and Skaggs both moved up to the Double-A Mobile BayBears.

They continued to climb through the Diamondbacks' organization before each made their major-league debuts in 2012: Skaggs in late August and Eaton in early September. 

In 2013 they each floated between the minors and majors, before they were each traded on Dec. 10. Eaton was traded to the White Sox and Skaggs to the Angels. 

While Skaggs had remained with Los Angeles since that 2013 trade, a second trade in 2016 sent Eaton to the Nationals, where he remains to this day.
