Parmley, whom the Blue Jays chose in the seventh round of the 2012 draft, made his major league debut last week but failed to reach base in any of his four plate appearances. The 27-year-old has spent nearly the entire season at Triple-A Buffalo, where he has hit .289/.332/.369 with one home run and 11 stolen bases in 205 PAs.
Unlike Parmley, Harrell has a fairly extensive big league track record. The 32-year-old is now set to put on his fifth major league uniform since debuting with the White Sox in 2010. The majority of Harrell’s action has come in Houston, where he pitched from 2011-14 and turned in two seasons of 150-plus innings. At his best, Harrell registered a 3.76 ERA, 6.51 K/9, 3.62 BB/9 and a 57.2 percent ground-ball rate across 193 2/3 frames in 2012.
After his run with the Astros ended, Harrell spent 2015 with the LG Twins of the Korea Baseball Organization. He resurfaced stateside last season and pitched in both the majors and minors with the Rangers and Braves organizations. In nine starts and 47 big league innings, Harrell logged a 4.21 ERA, 6.89 K/9, 4.79 BB/9 and a 44.3 percent grounder rate. He signed a minor league deal with the Jays over the winter and has combined for 27 2/3 frames between Double-A and Triple-A this season.
