Mercer announced Tuesday via his personal Twitter account that he has retired from professional baseball.

EDGE Analysis

Considering he turned 35 years old in August and didn't land an invitation to a big-league camp during the offseason, Mercer's decision to retire doesn't come as a major surprise. Mercer spent parts of 10 seasons in the majors with the Pirates, Tigers, Yankees and Nationals, compiling a .256/.315/.386 slash line and 66 home runs over 950 career games.

Mercer went 1-for-4 with a solo home run in Friday's 4-2 loss to Boston.

EDGE Analysis

The infielder went yard in the eighth inning, but that was the last of Washington's scoring in the contest. Mercer has hit safely in five of his last six games, going 6-for-25 (.240) in that span. He has a .261/.317/.369 slash line across 120 plate appearances while adding two homers, seven RBI and 13 runs scored in 44 contests this year. Mercer has seen less than a short-side platoon role at second base with Luis Garcia since the former returned from a calf injury in mid-September, although Mercer has also seen some playing time at the hot corner.

Mercer (calf) was reinstated from the 10-day injured list Monday, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

Mercer landed on the injured list with a left calf strain July 24, but he began a rehab assignment at Double-A Harrisburg last week. He went 3-for-9 with a run, two walks and three strikeouts across three rehab games and will rejoin the Nationals as utility depth after Adrian Sanchez was designated for assignment.

Mercer (calf) will begin a rehab assignment at Double-A Harrisburg on Wednesday, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

Mercer has been sidelined since July 24 due to a left calf strain, but he'll play second base and lead off in his return to game action Wednesday. The 35-year-old will likely require several rehab appearances following his lengthy absence, but he appears to be on track to rejoin the Nationals prior to the end of the regular season.

Mercer was placed on the 10-day injured list Saturday with a left calf strain, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

The infielder presumably suffered the injury July 20, which was the last game he appeared in. Mercer had just been activated from the IL on July 16 after recovering from a quadriceps strain, but now he's set for another absence. It's unclear how long he'll be sidelined. Carter Kieboom was recalled from Triple-A Rochester to provide infield depth in Mercer's absence.

Mercer (quadriceps) was activated from the 10-day injured list Friday, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

Mercer landed on the shelf June 2 with a quadriceps strain, and he'll rejoin the active roster after missing the past two weeks. The 34-year-old could see increased playing time in the immediate future with Starlin Castro placed on administrate leave for at least seven days.

Mercer (quadriceps) did some base running Friday for the first time since suffering the right quad strain, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

Mercer landed on the injured list July 2 and while he's eligible to return Sunday in San Francisco, it wouldn't be surprising to see the Nationals wait until after the All-Star break and give him some extra recovery time. Once active, Mercer figures to have a decreased role due to Alcides Escobar's arrival and offensive success.

Mercer was placed on the 10-day injured list Friday with a strained right quadriceps, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

The veteran infielder left Wednesday's contest with what was initially labeled quad cramps, but he's now been diagnosis with a sprain. It's unclear how long Mercer is expected to be sidelined. Humberto Arteaga was promoted from Double-A Harrisburg in a corresponding move and will start at shortstop Friday with Trea Turner (finger) also banged up.

Mercer (quadriceps) isn't starting Thursday's game against the Dodgers, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

The 34-year-old played through cramps in his quadriceps Wednesday, and he was further evaluated Thursday. Even though Trea Turner (hamstring) isn't starting, Mercer will be held out of the lineup while he recovers. He's still considered day-to-day, and it's not clear whether he could be available off the bench Thursday.

Mercer went 2-for-5 with a solo homer and two runs scored in Wednesday's win over Tampa Bay. Per Matt Weyrich of NBC Sports Washington, manager Davey Martinez said that Mercer is dealing with cramps in his quadriceps and will be further evaluated Thursday.

EDGE Analysis

Mercer received his first start since being hit in the mouth by a grounder last Thursday. The utility infielder popped his first homer of the campaign when he took Michael Wacha deep in the the fifth inning and he later singled and scored in the eighth. Both Mercer and Juan Soto dealt with leg cramps during the contest, though Mercer was able to stay in the game. Mercer will be looked at again Thursday and is considered day-to-day for the time being.
