EDGE Analysis

The unexpected day off hopefully won't cool off O'Neill, who's opened his latest big-league stint by going 5-for-8 over his first four games. The outfielder played all nine innings in Friday's loss, so it's presently unclear if the discomfort he's experiencing began at some point during that game. O'Neill will be considered day-to-day ahead of Sunday's series finale.

O'Neill went 3-for-5 with a run in a loss to the Pirates on Friday.

EDGE Analysis

O'Neill's latest big-league stint is off to a rousing start, as he's hit safely in all four games since returning while going 5-for-8 with two RBI, a walk, a stolen base and a run. The prodigious slugger has yet to leave the yard since his latest callup, but given his body of work at Triple-A Memphis in that regard, that doesn't figure to be the case for much longer.

O'Neill went 1-for-2 with an RBI and a walk Thursday against Colorado.

EDGE Analysis

O'Neill plated a run in the third inning on a sacrifice fly for his ninth RBI on the season. He's recording a base hit in four of his past six games, going 5-for-12 with two RBI over that stretch. O'Neill is slashing .280/.309/.480 with three homers and a .789 OPS over 22 games this season.

EDGE Analysis

Just recalled from Triple-A Memphis earlier in the day, O'Neill was immediately slotted into the lineup by interim manager Mike Shildt. The prodigious rookie had recently been on another one of his trademark home-run tears with the Redbirds, and with Tommy Pham having been dealt to the Rays at the deadline, O'Neill's projects to have an extended opportunity to replicate the feat at the big-league level.

O'Neill will be recalled from Triple-A Memphis on Tuesday, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

O'Neill is expected to join the club prior to Tuesday's game against the Rockies to take the roster spot of Tommy Pham, who was dealt to Tampa Bay earlier in the day. Across 19 games with the Cardinals during various stints with the team this year, he's gone 10-for-44 (.227 average) with three home runs and seven RBI. With Pham out of the picture, O'Neill should slide in as a fourth outfielder behind Marcell Ozuna, Harrison Bader and Dexter Fowler. Look for him to receive some playing time at the corner outfield spots, especially in right field.

EDGE Analysis

O'Neill's fifth multi-homer effort of the season helped him move into a tie with Salt Lake's Jabari Blash for the Pacific Coast League lead with 23. The 23-year-old's credentials as a power hitter aren't in dispute, but there remain some concerns about his plate discipline, which could harm his chances of claiming a full-time role with the Cardinals. Over his multiple stints in the big leagues this season, O'Neill has homered three times in 47 plate appearances, but has posted an ugly 1:20 BB:K.
