Castillo retired from professional baseball on Sunday, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

Castillo last saw game action with Triple-A Rochester in mid-June, and he's opted to hang up his cleats. The 34-year-old played 10 years in the big leagues and had a .254/.313/.426 slash line with 98 homers in 726 games between the Cubs, Diamondbacks, White Sox, Mariners and Orioles.

Castillo (shoulder) has appeared in five games this season for Triple-A Rochester, going 3-for-11 with seven walks and an RBI.

EDGE Analysis

Castillo is healthy again after he was slowed during the Nationals' big-league spring training due to a shoulder issue. The injury took him out of the running for a spot on the Opening Day roster for the big club, and the 34-year-old will likely have to wait for an injury to either Yan Gomes or Alex Avila before he receives consideration for a call-up.

Castillo (shoulder) was assigned to minor-league camp Saturday, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

Castillo was merely in camp as a non-roster invitee, making him always a long shot to open the season in the big leagues. He's been dealing with a shoulder issue all spring and hasn't gotten into a single spring training game, eliminating whatever slim chance he had of making the Opening Day roster.

Nationals manager Dave Martinez said Wednesday that Castillo has been battling a shoulder injury since the start of camp, but the catcher has since been cleared to resume a throwing program, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

Castillo has yet to play in any of the Nationals' Grapefruit League games thus far because of the injury, but with Martinez noting that the 33-year-old is in the process of building up to game speed, his spring debut could be imminent. Yan Gomes and Alex Avila will head into Opening Day as the Nationals' clear top two catchers, so Castillo is realistically battling Tres Barrera for the No. 3 spot on the depth chart, if the team elects to break camp with three backstops.

Castillo signed a one-year minor-league deal with the Nationals on Monday, Bob Nightengale of USA Today reports.

EDGE Analysis

Castillo will earn $950,000 if he makes the big-league roster. The veteran backstop signed a similar deal with the Nationals last offseason but wound up opting out of the season due to the COVID-19 pandemic. He owns a respectable .254/.313/.426 slash line over his decade-long big-league career but may not be suited for anything other than backup duties at this point, as his .209/.267/.417 line for the White Sox in 2019 suggests.

The Nationals placed Castillo (opt out) on the restricted list July 4.

EDGE Analysis

Washington made the transaction official one day after manager Dave Martinez told the media that Castillo became the third player to sit out the 60-game season. Castillo joined the Nationals in January on a one-year deal, so he'll head to the open market at the conclusion of the 2020 campaign.

Manager Dave Martinez announced Friday that Castillo has opted out of the 2020 season, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

Castillo is the third Nationals player to elect to sit out, joining Ryan Zimmerman and Joe Ross. Castillo was a non-roster invitee but had a decent chance of making the expanded Opening Day roster as the team's third catcher before choosing to forgo the the season.

Castillo (shoulder) is in the lineup for Saturday's split-squad game against the Marlins, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

Castillo did not start a game between Feb. 28 and Friday, but he served as the DH in that game and is ready to get back behind the plate Saturday, so it appears he has put his shoulder injury behind him. He will continue his pursuit of a roster spot, but he faces an uphill battle with Kurt Suzuki and Yan Gomes ahead of him.

Castillo is dealing with a sore right shoulder, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

Castillo was supposed to serve as the designated hitter for Saturday's game and catch Sunday, but his sore shoulder is limiting his availability. The exact severity of the injury is unclear, but it appears that the 32-year-old could be sidelined for the first few games of spring training.

Castillo signed with the Nationals as a non-roster invitee Friday, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

The 10-year veteran was largely unimpressive in 72 games for the White Sox last season, hitting .209/.267/.417 with 12 homers. His career 98 wRC+ is perfectly respectable for a catcher, though it likely doesn't reflect his current talent level heading into his age-33 season. The Nationals appear to be set at the catcher position with Kurt Suzuki and Yan Gomes both returning, so Castillo might wind up as nothing more than injury insurance.
