ESPN | Buster Olney: September 1st brings the start of expanded rosters and Wednesday afternoon, we learned the Yankees are intending to call up top prospects Jasson Domínguez and Austin Wells to make their major league debuts against the Astros. After a slow start to his minor league career — understandable due to his age — the Martian seems to have turned a corner these last two years. He was recently promoted to Triple-A, where he’s 12-for-27 with a 187 wRC+ in eight games, and owns a .801 OPS with 15 home runs, 76 RBI, and 39 stolen bases in 117 games at Double- and Triple-A this year.
