The Braves released O'Brien on Monday.

EDGE Analysis

According to David O'Brien of The Athletic, during the latter stages of summer camp, O'Brien was exposed to someone who tested positive for COVID-19, derailing any hope he had of cracking the Braves' season-opening 30-man roster. Though O'Brien has presumably cleared all COVID-19-related protocols, the Braves evidently determined he wasn't worth keeping around at their alternate training site in Gwinnett. The Braves added 2020 fourth-round pick Spencer Strider to the 60-man roster pool in a corresponding move.

O'Brien (undisclosed) was placed on the 10-day injured list Thursday, Andersen Pickard of MLBDailyDish.com reports.

EDGE Analysis

The reasoning behind O'Brien's move to the injured list is not clear. The 29-year-old, who owns a career .209/.275/.434 slash line across 200 major-league plate appearances, joined the Braves as a non-roster invitee in January and will serve as organizational depth once healthy.

O'Brien will be a part of the Braves' 60-man roster, Gabe Burns of The Atlanta Journal-Constitution reports.

EDGE Analysis

O'Brien joined the braves as a non-roster invitee in January and went 6-for-32 with four home runs and seven RBI during spring training, although he also struck out 13 times. The 29-year-old has had limited results in the majors during short stints over four seasons, hitting .209/.275/.434 with 11 home runs and 73 strikeouts over 200 plate appearances. Given his inability to carve out a major-league role in the past, it's unlikely that he'll be a big part of the Braves' major-league plans in 2020.

O'Brien joined the Braves as a non-roster invitee Wednesday.

EDGE Analysis

O'Brien has received 200 big-league plate appearances over parts of four seasons but hasn't done much with them, hitting .209/.275/.434 with a 36.5 percent strikeout rate. He'll likely be an organizational depth option for the Braves this season.

O'Brien (ribs) went 0-for-3 with a walk and a strikeout in his first game back with Triple-A New Orleans on Tuesday.

EDGE Analysis

A rib injury put O'Brien on the major-league injured list in May and the Marlins ultimately decided he was not worth waiting around for; they designated him for assignment June 20 to make room for Zac Gallen. The 28-year-old O'Brien cleared waivers and has since been cleared to return to active competition with New Orleans, where he is likely to play out the remainder of the campaign, with an outside shot at a September callup.

O'Brien (ribs) cleared waivers and was outrighted to Triple-A New Orleans on Saturday, Jordan McPherson of the Miami Herald reports.

EDGE Analysis

O'Brien had been on the injured list for more than a month when he was designated for assignment Thursday. He'll fill an organizational depth role for the Marlins once healthy.

O'Brien (ribs) was designated for assignment Thursday, Jordan McPherson of the Miami Herald reports.

EDGE Analysis

O'Brien has been sidelined for nearly a month with a rib injury. Prior to landing on the shelf, the 28-year-old slashed just .167/.255/.262 in 14 games, so the Marlins decided to drop him from their 40-man roster rather than wait for him to get healthy. This move frees up a spot on Miami's 40-man roster for Thursday's starter, Zac Gallen, whose contract was purchased from Triple-A New Orleans.

O'Brien (ribs) will begin a rehab assignment with High-A Jupiter on Tuesday, Jordan McPherson of the Miami Herald reports.

EDGE Analysis

O'Brien will be eligible to return from the injured list Friday and appears to be tracking for a return close to that date. It's not clear that he'll have a big-league role to return to once healthy, however, as he's hit just .167/.255/.262 in 14 games for the Marlins this season.

O'Brien was placed on the 10-day injured list with a left rib cage contusion Saturday.

EDGE Analysis

O'Brien is hitting just .167/.255/.262 in 14 games for the Marlins this season. Garrett Cooper (hand) was reinstated from the injured list in a corresponding move.

O'Brien is out of the lineup for Sunday's game against the Braves, Joe Frisaro of MLB.com reports.

EDGE Analysis

The Marlins brought O'Brien back from the minors on Saturday and immediately installed him as the starting left fielder in place of the injured Garrett Cooper (hand). Though Cooper will remain on the injured list for at least the next week and a half, O'Brien won't be promised full-time run in the outfield unless his bat warrants the steady playing time. O'Brien has registered just four hits while striking out 15 times in 30 at-bats with Miami this season.
