O'Neill went 2-for-4 with a solo home run, two runs scored and a walk in Sunday's 9-5 win over the Reds.

EDGE Analysis

O'Neill had just two extra-base hits prior to Sunday's game as he's still looking to earn an everyday role. It was also just his second multi-hit game of the season. His OPS is up to .803 in 28 plate appearances.

O'Neill went 1-for-2 with an RBI infield single in an extra-inning win over the Pirates on Wednesday.

EDGE Analysis

O'Neill's 10th inning infield hit plated Kolten Wong to snap a 4-4 tie. The slugging outfielder has yet to leave the yard in the five games during which he's made an appearance this season, but he's now hit safely in three of his last four. With Marcell Ozuna (side) ailing and scheduled for a Thursday MRI, the possibility of O'Neill being afforded much more consistent playing time in the near future looms as a distinct possibility.

O'Neill has made the Opening Day roster as a reserve outfielder, Jenifer Langosch of MLB.com reports.

EDGE Analysis

The young slugger slammed a team-high five home runs in Grapefruit League play and laced eight extra-base hits over 10 at-bats overall. It will be the second regular-season major-league stint for O'Neill, who held his own as a rookie in 2018 by posting a .254/.303/.500 line with nine home runs and 23 RBI over 142 plate appearances. The 23-year-old is capable of backing up all three outfield positions, which could afford him a solid amount of playing time over the course of the season if he hangs on to a spot with the big club.

O'Neill went 1-for-3 with a solo home run Monday against the Phillies.

EDGE Analysis

O'Neill continued his all-or-nothing approach at the plate this spring, taking Zach Eflin deep in the second innings for his fifth home run. While he's making more contact -- he has 11 strikeouts in 37 at-bats -- he has still managed just a .216 batting average. O'Neill remains locked in a battle for playing time with Dexter Fowler, though he is likely to begin the season in a reserve role.

O'Neill went 2-for-4 with a double, a solo home run, two RBI and two runs overall in the Cardinals' 9-5 Grapefruit League win over the Yankees on Wednesday. He now has four home runs and six RBI across 21 spring at-bats.

EDGE Analysis

In the wake of a 2018 campaign when he launched a combined 35 homers between Triple-A Memphis and the big-league club, O'Neill looks ready to pick right back up where he left off. The slugging 23-year-old still has plenty of work to do with respect to plate discipline, but his power upside is enticing. O'Neill is battling for a reserve outfield role this spring, and his ability to fill in at all three spots certainly serves as a plus alongside his power-hitting exploits.

O'Neill went 1-for-2 with a solo homer, a walk and an additional run scored Friday against the Astros.

EDGE Analysis

O'Neill walked in his first trip to the plate, coming around to score on a single from Rangel Ravelo. He added a solo homer later in the game, his second of spring (though also just his second hit in 12 at-bats).

O'Neill went 1-for-2 with his ninth home run in Saturday's 5-4 extra-inning win over San Francisco.

EDGE Analysis

O'Neill came into the game in the seventh inning as part of a double switch, and delivered the Cardinals' 11th walkoff win of the season with a home run off Mark Melancon. The 23-year-old has only received 21 at-bats in September, but remains a valuable power source off the bench.

O'Neill went 1-for-1 with a walk and a three-run home run in Tuesday's 11-5 win over the Pirates.

EDGE Analysis

O'Neill really put the game out of reach when he clubbed a pinch-hit three-run homer -- his eighth of the year -- off Nick Burdi in the eighth inning to give the Cardinals an eight-run lead. Prior to the blast O'Neill had gone hitless over his last 11 at-bats, striking out seven times against no walks. It's a small sample size, but as the 23-year-old is competing for playing time in St. Louis' outfield, every bit helps make his case for at-bats, especially as the Cardinals make a run for the playoffs.

O'Neill is out of the lineup Sunday against the Reds.

EDGE Analysis

After starting each of the past eight games and batting .212 with three home runs, O'Neill will bow out of the starting nine with a healthy Marcell Ozuna (shoulder) reclaiming an everyday role in left field. O'Neill hasn't lacked in power across his multiple stops in the big leagues and has slugged 33 home runs between the majors at Triple-A Memphis this season, but his poor plate skills (41.1 K%) hurt his case for steady at-bats.

O'Neill sent 2-for-5 with a two-run home run and two runs overall in a win over the Rockies on Sunday.

EDGE Analysis

The thin air of Coors Field proved an ideal match for O'Neill's potent bat, as the slugging outfielder generated a pair of multi-hit efforts -- which included three extra-base hits (one double, two homers) -- over the three-game set. The 23-year-old has left the yard in three of the last four contests overall, and he's hitting .341 (14-for-41) over the 14 games he's played in his current major-league stint.
