MLBTR named Markakis along with Aybar among the 7 trade candidates who have hurt their stock:
Erick Aybar: When the rebuilding Braves acquired Aybar from the Angels as part of the Andrelton Simmons package, their hope was that he’d serve as a sturdy shortstop bridge between Simmons’ reign and the Dansby Swanson/Ozzie Albies era. Aybar has instead been the worst player on arguably the majors’ worst team, having hit .175/.216/.204 in 151 trips to the plate. The 32-year-old’s 7 wRC+ is easily last among qualifying hitters (his closest company is at 43), as is his minus-1.6 fWAR. The Braves had a high asking price on Aybar as of March, but they’ll have difficulty finding anyone willing to take the $8.5MM infielder in the last year of his contract if his play doesn’t substantially improve.
Nick Markakis: The Braves reportedly had opportunities to trade Markakis last winter and in 2015, but they elected to retain the right fielder instead. Considering that Markakis is on a $10.5MM annual salary from now until the end of 2018, Atlanta might regret not dealing the 32-year-old. Since joining the Braves last season, the power Markakis showed in Baltimore from 2006-14 has disappeared. In 871 PAs with the Braves, Markakis has totaled just four home runs – two fewer than Giants pitcher Madison Bumgarner, who has amassed 765 fewer PAs – and logged the majors’ fifth-worst ISO (.083). To Markakis’ credit, he has managed to produce a decent 105 wRC+ with the Braves and has gotten on base at an impressive 36.9 percent clip, but a well-compensated, power-devoid corner outfielder who doesn’t grade well defensively simply doesn’t have much value.
