Sierra was optioned to Triple-A New Orleans, Andre Fernandez of The Athletic reports. Through 220 MLB plate appearances, Sierra has just a .227/.263/.242 line, and his Triple-A numbers (.260/.287/.341) aren't much better. If he can show signs of improvement, it is possible he could be a cheap source of steals sometime this summer, but he will likely always be a batting average liability in the majors.
Sierra is not in the lineup for Saturday's game against the Mets, Clark Spencer of the Miami Herald reports. Sierra sits after making seven straight starts. He's hitting just .212/.281/.212 in September, dragging his slash line up to a miserable .188/.220/.201. Isaac Galloway will get the start in right field in Sierra's place.
Sierra is not in the lineup against Boston on Wednesday, Clark Spencer of the Miami Herald reports. Sierra will take a seat for the second straight day as Isaac Galloway gets another start in center field for Wednesday's series finale. Since the beginning of August, Sierra is hitting just .138/.138/.154 with one extra-base hit and 17 strikeouts in 65 at-bats.
Sierra is not starting Tuesday against the Red Sox, Andre Fernandez of the Miami Herald reports. Sierra has been the primary center fielder in Miami with Lewis Brinson (hip) injured and Cameron Maybin shipped to Seattle. He hasn't performed well in that role, hitting a miserable .161/.161/.184 through 27 games, leading to Isaac Galloway starting for the fourth time in nine games. Galloway has gone 9-for-31 so far this season and could be moving ahead of Sierra, though Lewis Brinson will likely leapfrog them both once his rehab assignment ends, which is likely to happen soon.
Sierra will start in center field and bat eighth Sunday against the Braves, Clark Spencer of the Miami Herald reports. Sierra was benched in favor of Isaac Galloway for two consecutive games last weekend, but the 22-year-old has since settled back into the starting nine on a regular basis. Though he'll be in the lineup for the fifth time in six games Sunday, Sierra will need to raise his performance before becoming a trusted fantasy option, even in most deep leagues. Over 88 plate appearances this season, Sierra has slashed .165/.165/.188 with no home runs, one stolen base and a 0:25 BB:K.
