O'Neill was recalled from Triple-Memphis by the Cardinals on Friday.

EDGE Analysis

O'Neill had an uneventful six-game stint in the majors earlier this season before being sent to Memphis in late April, and has been tearing the cover off the ball of late. The 22-year-old has a .319 batting average with 13 home runs and 31 RBI in 113 at-bats in Triple-A, but has no clear path to playing time in St. Louis with Marcell Ozuna, Tommy Pham, Dexter Fowler and Harrison Bader all currently healthy in the team's outfield.

O'Neill went 2-for-3 with a pair of solo home runs for Triple-A Memphis in its 2-1 win over Nashville on Monday.

EDGE Analysis

O'Neill has now gone deep four times in Memphis' last three contests, bringing his home-run count up to 13 across just 111 plate appearances at Triple-A. That total is tied for the second-most in all of the minors, an achievement rendered even more impressive by O'Neill having appeared in six games for the Cardinals earlier this season. While O'Neill's 1.9 percent walk rate leaves something to be desired, it doesn't look to be a major impediment to him eventually rejoining the big club. Instead, it's the Cardinals' ample depth in the outfield that has prevented a permanent stay in the majors for O'Neill, who will likely need to wait for one of Marcell Ozuna, Tommy Pham or Dexter Fowler to succumb to an injury before receiving an extended look from St. Louis.

O'Neill went 3-for-8 with two home runs and four RBI for Triple-A Memphis in two games against Nashville on Saturday and Sunday.

EDGE Analysis

That's five round trippers for O'Neill in the last nine games, a torrid stretch during which he's driven in nine runs. The slugging outfielder is going to be difficult to keep down on the farm if he continues to churn out the caliber of effort that's led to a .324/.333/.696 line over 26 games with the Redbirds. O'Neill already had one brief cup of coffee with the big-league club this season, going hitless over nine plate appearances.

O'Neill is 6-for-12 with a pair of solo home runs and four runs overall in his last three games for Triple-A Memphis.

EDGE Analysis

The surge has pushed O'Neill's season line with the Redbirds to .354/.353/.695 over 82 at-bats. The slugging outfielder recently logged a brief major-league stint with the Cardinals, but he went hitless over nine plate appearances. O'Neill's improvement in Triple-A this season has been notable, considering he'd hit no better than .253 in his two prior stops at that level.

O'Neill was optioned to Triple-A Memphis on Saturday.

EDGE Analysis

O'Neill was sent down in order to make room for Jack Flaherty, who makes his second start of the season Saturday against the Pirates. O'Neill possesses prodigious power, but he didn't get a chance to show it in his brief stay with the Cardinals, going hitless in nine plate appearances. Still, he's clearly right on the fringe of the big-league roster, so an injury to a starting outfielder in St. Louis could give him another chance to show what he can do.

O'Neill was called up from Triple-A Memphis on Thursday.

EDGE Analysis

In a corresponding move, the Cardinals optioned John Brebbia to Memphis. O'Neill is set to make his major-league debut in the coming days following a terrific start to the 2018 campaign at the Triple-A level. Over 12 games, O'Neill was hitting .388/.385/.837 with six home runs and 18 RBI. Since the 22-year-old did not take the spot of Tommy Pham (groin) on the active roster, it appears as though the latter received positive news after experiencing tightness in his right groin during Tuesday's contest. If Pham doesn't require any time off, expect O'Neill to serve out of a reserve role in the outfield with occasional starts in the Cardinals' lineup.

O'Neill is expected to be called up by the Cardinals prior to Thursday's game against the Cubs, Joe Trezza of MLB.com reports.

EDGE Analysis

O'Neill has been scorching hot at the Triple-A level to open the 2018 season, hitting .388 with a 1.222 OPS and six home runs in just 12 contests. The 22-year-old wasn't able to show his potential in spring training as he dealt with a strained oblique and then a hamstring strain which limited him to just seven games in the Grapefruit League. O'Neill will provide added depth in the Cardinals' outfield moving forward and is expected to take the roster spot of a reliever when the move occurs Thursday.

O'Neill went 3-for-5 with four RBI from a pair of two-run home runs and scored three runs overall in Triple-A Memphis' 7-4 win over Iowa on Monday.

EDGE Analysis

The 22-year-old has been terrorizing Triple-A pitching since the season began, with Monday's outburst pushing his average to .432 over his first 47 plate appearances. That impressive number is partly comprised of nine extra-base hits (six home runs, two doubles and one triple) and he's already knocked in a whopping 18 runs over 11 games. His homer total notably ties him with the Padres' Josh Naylor for tops in all of the minors.

O'Neill has three home runs and seven RBI over his first three games for Triple-A Memphis.

EDGE Analysis

He had a quiet spring with the Cardinals before being reassigned to minor-league camp March 11 shortly after suffering a hamstring injury. He's been a man on a mission over the Redbirds' first three contests, however, with four of his five hits going for extra bases. O'Neill slugged a combined 31 round trippers last season between Triple-A Tacoma (while still with the Mariners) and Memphis, so the early surge isn't overly surprising.

O'Neill (hamstring) was reassigned to minor-league camp Sunday, Joe Trezza of MLB.com reports.

EDGE Analysis

O'Neill wasn't expected to return this spring due to his recent hamstring injury. He appeared in seven Grapefruit League games, going 3-for-12 with seven strikeouts over said outings. While he's in line to open the year at Triple-A Memphis, he could earn a chance to play in the Show over the course of the upcoming season.
