Grossman, 26, signed a minor league pact with Cleveland this winter but didn’t make the club out of Spring Training despite the club’s thin outfield mix (though he slashed a rather solid .231/.348/.385 with three homers). The former Astro has hit quite well in the early stages of the 2016 campaign, batting .256/.370/.453 with six homers and three steals for Triple-A Columbus. He was once looked at as a possible building block in Houston, who acquired him alongside Rudy Owens and Colton Cain in the 2012 trade that sent Wandy Rodriguez to the Pirates. However, after a strong .268/.332/.370 debut as a 23-year-old in 2013, Grossman went on to bat just .222/.323/.323 in the two subsequent seasons. Lackluster performance in 2014-15 notwithstanding, the switch-hitting Grossman should draw some interest as a free agent given his relative youth, solid Triple-A production and experience in the Majors.
He joins a growing list of players that have exercised mid-May opt-out clauses, joining veteran lefties Brian Duensing and David Huff — each of whom opted out of their respective contracts with the Royals on Sunday — and catcher Michael McKenry, who opted out of a minor league pact with the Rangers on Saturday.
