Harrison has been diagnosed with a right groin strain and is expected to be out 4-to-6 weeks, Rob Biertempfel of the Pittsburgh Tribune-Review reports.

EDGE Analysis

Harrison should be recovered from his setback at some point in October, but with the Pirates fading fast in the playoff hunt, he is likely done for the season. Adam Frazier and Sean Rodgriguez are favorites to see increased action at second base the rest of the way.

Harrison (groin) won't play Monday and has no timetable for a return, reports.

EDGE Analysis

The second baseman sat out Sunday's game after injuring his right groin while running the bases Saturday. Harrison is riding a 10-game hitting streak and is batting .383/.400/.483 in his last 66 plate appearances. A combination of Sean Rodriguez, Alen Hanson and Adam Frazier will likely see action at second base with Harrison sidelined.

Pirates GM Neal Huntington clarified Sunday that Harrison's groin injury is more severe than a day-to-day situation, Bill Brink of the Pittsburgh Post-Gazette reports.

EDGE Analysis

Harrison suffered the injury during Saturday's tilt with the Reds and was replaced in the lineup by Sean Rodriguez on Sunday. With Harrison's return date up in the air, it may make sense to keep him on the bench in weekly formats in favor of a healthier player. In the meantime, the Pirates figure to use Rodriguez and Adam Frazier more liberally at second base, and perhaps everyday shortstop Jordy Mercer could see some time at the position as well.

Harrison (groin) is out of the lineup Sunday against the Reds, Adam Berry of MLB.com reports.

EDGE Analysis

EDGE Analysis

The leadoff man opened the scoring by plating Jody Mercer with a third-inning two-bagger, plating Jody Mercer and erasing an early 1-0 deficit in the process. Harrison has been on a tear at the plate, with a nine-game hitting streak that includes all of his September contests so far, and six multi-hit efforts. He's slashing a stellar .394/.400/.515 over his first 33 at-bats of the month, as well as a solid .294/.318/.406 overall in the second half of the season.

Harrison went 3-for-5 with a two-RBI single and two runs in Saturday's 9-6 victory over the Brewers.

EDGE Analysis

The leadoff man brought the Pirates closer in a pivotal fourth inning by plating Jody Mercer and Eric Fryer with a bases-loaded single, and enjoyed his sixth multi-hit outing of August. Harrison has a modest three-game hitting streak and has hit safely in nine of his last 12 overall. With the pair of runs driven in Saturday, he's now one RBI away from equaling the career-best figure of 52 that he achieved back in 2014.

Harrison went 1-for-4 with a walk Friday while batting leadoff for the 18th time in August.

EDGE Analysis

After a hot start while hitting atop the order, Harrison has managed two hits in his last 20 at-bats. He's not a prototypical leadoff man, but remains Pittsburgh's best choice, according to manager Clint Hurdle. It wouldn't be surprising to see Adam Frazier give Harrison a break in the coming days. For the season, Harrison is batting .269/.298/.375 with four homers and 16 stolen bases.

Harrison went 3-for-4 with an RBI single and double in Saturday's 3-1 loss to the Marlins.

The leadoff man was the only meaningful contributor in the Pirates lineup on a day when David Phelps and an array of Marlins relievers shut down their offense. Harrison saved Pittsburgh from the indignity of a shutout by plating Jody Mercer with an eighth-inning single, and now has a six-game hitting streak and an RBI in three straight games.
