Harrison tore the UCL in his left thumb on July 6 — an injury that required surgery to correct. He’s returned to action slightly faster than the Pirates anticipated, as their initial announcement said he’d be sidelined for seven weeks. The loss of Harrison left the Pirates short-handed and contributed to the acquisition of Aramis Ramirez. Now that Harrison is back, he’ll presumably split time at third base and in right field, possibly at the expense of some playing time for Ramirez and Gregory Polanco. Given his defensive prowess and solid bat, it’d be surprising if Harrison weren’t in the lineup on an everyday basis.
Wall, 28, had his contract selected to the roster earlier this week after a 15-inning game that left Pittsburgh’s bullpen short-handed. Wall has appeared in the Majors in each of the past three seasons, totaling 13 2/3 innings, but he’s yet to pitch in the Major Leagues this season. Instead, he’s spent the year at the Triple-A level, where he owns a very strong 2.93 ERA with 8.5 K/9 and 2.6 BB/9 in 30 2/3 innings.
