Assuming no setbacks, Starling Marte (fractured rib) is on track to rejoin the Marlins active roster next week. During his absence, Magneuris Sierra has been Miami’s most frequently used center fielder. Any way you slice it, Sierra’s production pales in comparison to Marte’s, and his track record prior to 2021 does not inspire much confidence, either. On the surface, he looks like a candidate to be designated for assignment in the near future.
Yet remarkably, while Marte has been sidelined and especially when Sierra has started in his place, the Marlins have stayed afloat.
