Sierra was optioned to Triple-A New Orleans on Tuesday, Joe Frisaro of MLB.com reports.
Sierra, one of the team's top prospects, was one of the headliners acquired from the Cardinals in a December trade that sent Marcell Ozuna to St. Louis. Despite seeing 64 plate appearances with the Cardinals in 2017, the soon-to-be 22-year-old has yet to appear at Triple-A, so he'll report to New Orleans to start the season as he continues to refine his offensive game.
A tight left hamstring has kept Sierra out of the Marlins' Grapefruit League lineup since March 14, but it appears his health is trending in the right direction as the team prepares to break camp. Even so, the week-plus absence may have been enough to damage Sierra's chances of cracking the Opening Day roster. Derek Dietrich, Lewis Brinson and Cameron Maybin appear in line to open the season as the Marlins' starting outfielders, so the organization may not have much interest in keeping the 21-year-old Sierra with the big club as an underused bench player.
Manager Don Mattingly indicated Tuesday that Sierra (hamstring) would likely be sidelined a couple days, Andre Fernandez of the Miami Herald reports.
Sierra exited Wednesday's spring game against the Mets with hamstring tightness but may be able to return to action this weekend or early next week. The 21-year-old was likely to start the season in the minor leagues regardless and it would make sense for the Marlins to avoid rushing him back.
Sierra is day-to-day with left hamstring tightness, Andre Fernandez of the Miami Herald reports.
Sierra was removed from Wednesday's game against the Mets after pulling up limping following a groundout. The initial diagnosis of hamstring tightness does not appear to be too serious, though more could be known after further tests.
Sierra was removed from Wednesday's contest with an apparent leg injury after limping back to the dugout following a groundout, Joe Frisaro of MLB.com reports.
Braxton Lee replaced Sierra in center field following his at-bat. There has been no official word as to what sort of injury he sustained but an update on his status will likely be released in the coming hours.
