O'Brien was recalled from Triple-A Reno on Friday, Steve Berthiaume of Fox Sports Arizona reports.

EDGE Analysis

O'Brien, who was hitting .330 for Reno with 17 home runs in 51 games, will take the spot of Edwin Escobar, who was optioned down. It's unclear what exactly O'Brien's role will be, but the 25-year-old does offer considerable pop when he's in the lineup.

O'Brien was optioned to Triple-A Reno on Sunday, Steve Gilbert of MLB.com reports.

EDGE Analysis

O'Brien was optioned in order to make room for Edwin Escobar starting in Rubby De La Rosa's place in Monday's game against the Astros. O'Brien received one at-bat in his short stint in the majors, for one strikeout. O'Brien has performed well at the Triple-A level in 2016, slashing .306/.330/.601, and could be called up again later in the season.

O'Brien was recalled from Triple-A Reno on Friday.

EDGE Analysis

O'Brien was in consideration for a callup after the Diamondbacks outfield became fairly thin due to injuries, and it seems like the organization is ready to give the converted catcher a chance at the big league level. The 25-year-old crushed Triple-A pitching to the tune of a .306/.330/.601 slash line, so if he can continue his mashing ways with the parent club, he could force his way into a larger role. He'll likely begin his tenure in the majors as a reserve outfielder, though.

O'Brien has been discussed as a candidate to provide the Diamondbacks with outfield help, Barry M. Bloom of MLB.com reports.

EDGE Analysis

With injuries to both A.J. Pollock and David Peralta thinning the Arizona outfield, manager Chip Hale said the team has discussed calling up O'Brien. "We talked about that scenario, getting him back up here and giving him an opportunity, but who are you going to sit?" Hale said. "It's hard to find a spot for a start. Would he be good off our bench?" For now, O'Brien will remain in Triple-A, where he has a .322 batting average, .993 OPS, 12 home runs and 31 RBIs in 35 games. He'd be a perfect fit as a DH, but for now the converted catcher will have to keep working on his outfield defense if he hopes to earn a regular role with the Diamondbacks.

O'Brien was named the Diamondbacks' Player of the Month for April on Monday.

EDGE Analysis

The 25-year-old slugger hit .370 with five doubles, seven home runs and 21 RBI in 20 games for Triple-A Reno. O'Brien is still working on the defensive transition from catcher to outfielder, but his bat appears MLB-ready. He had a brief stint with the Diamondbacks last season and will likely earn himself big league playing time again this year.

O'Brien went 1-for-4 with a three-run home run on Monday for Triple-A Reno, his first home run of the season.

EDGE Analysis

O'Brien slashed .284/.332/.551 with 28 home runs and 107 RBI at Triple-A Reno last season, and he was one of the last cuts from the big league roster this spring, so the 25-year-old shouldn't be too far from a call up if he continues to play well in the minors. He still figures to need work defensively in the outfield, as he came up through the minors mainly as a catcher. He's started all three games so far this season in left field.

The D-backs optioned O'Brien to Triple-A Reno as part of their final roster cuts.

EDGE Analysis

Socrates Brito made the Opening Day roster on the heels of A.J. Pollock's elbow injury Friday. O'Brien is still a work in progress defensively, but the return to Triple-A to begin the year will give him an everyday opportunity for reps in left field.

O'Brien went 1-for-3 with a three-run home run in Tuesday's 7-7 tie with San Francisco.

EDGE Analysis

There was no doubt from the second the ball left O'Brien's bat that his eighth-inning hit was leaving the park. According to MLB.com, it was the hardest-hit ball ever recorded by Statcast at 119.5 mph, with a projected distance of 462 feet. The left field battle in Arizona is really heating up with Yasmany Tomas, Socrates Brito, O'Brien, and even Rickie Weeks in the hunt for playing time.

Diamondbacks manager Chip Hale said O'Brien has "blossomed" at the plate lately, the Arizona Republic reports.

EDGE Analysis

After starting 1-for-9 in Cactus League play, O'Brien has 10 hits in his last 26 at-bats. He also leads the team with three home runs and 11 RBI this spring. Regular playing time might still elude him, however, as he hasn't looked comfortable in the outfield and Arizona has some depth there. O'Brien has played once at first this spring and has yet to catch.

O'Brien hit two home runs and drove in five on Sunday, the team's official site reports

EDGE Analysis

O'Brien is known for his power, and it was on display in this one. The 25-year-old is focusing on the outfield this spring after coming up as a catcher. His path to regular playing time is blocked at the moment, but he could be a fantasy factor if he gets enough at-bats.
