Gonzalez announced Thursday via his personal Instagram account that he has elected to retire from professional baseball.

EDGE Analysis

Gonzalez had been attending camp with the Marlins as a non-roster invitee, hoping to secure a spot on the team's Opening Day roster as a fifth starter. With Trevor Rogers and Nick Neidert having emerged as the clear frontrunners for the final rotation spot, Gonzalez determined he was best off stepping away from the game rather than reporting to the Marlins' alternate training site at the conclusion of camp. The 35-year-old lefty spent parts of 13 seasons in the majors with the Athletics, Nationals, Brewers and White Sox, going 131-101 with a career 3.70 ERA while earning two All-Star nods.

Gonzalez threw a 32-pitch live batting practice session Monday, Christina De Nicola of MLB.com reports.

EDGE Analysis

Gonzalez continues to ramp up his throwing progression after signing a minor-league deal with Miami earlier in the month. The southpaw's fastball reportedly sat around 91 mph, which, as De Nicola notes, would be his highest velocity since the 2016 campaign. "I thought it was really good," stated skipper Don Mattingly. "His breaking ball had more action today. The guys that were hitting said it was tougher to pick up today, it was staying closed longer." The club has yet to decide when Gonzalez will throw next, but he'll continue to compete for a spot in the starting rotation as spring camp rolls on.

Gonzalez signed a minor-league contract with the Marlins on Wednesday, Craig Mish of SportsGrid.com reports.

EDGE Analysis

Gonzalez had been a free agent since having his club option declined by the White Sox in October, but he finally latched on with a new squad, and it is essentially the hometown team for the South Florida resident. Gonzalez's deal includes an invitation to big-league camp, so he will have a chance to earn a roster spot in the weeks ahead. He struggled a bit last season but did post a 3.50 ERA and 1.29 WHIP with the Brewers two years ago, so he may have a little bit left in the tank.

The White Sox declined Gonzalez's (undisclosed) $7 million club option for 2021 on Friday.

EDGE Analysis

The veteran left-hander posted a 4.83 ERA, 1.86 WHIP and 34:19 K:BB over 31.2 innings this season, so it's no surprise to see Chicago electing to pay the $500,000 buyout. Gonzalez suffered an undisclosed injury during the final game of the regular season and was left off the playoff roster, and it's unclear if he's fully recovered from that issue.

Gonzalez (undisclosed) is not part of the White Sox's roster for the AL Wild Card Series against Oakland.

EDGE Analysis

Gonzalez left his final outing of the year Sunday against the Cubs with an undisclosed injury. It's not clear whether his absence from the roster is injury-related or if the team simply didn't foresee him playing a role during the three-game series. He wasn't particularly impressive in four starts and eight relief appearances this season, as his 4.83 ERA came with a 1.86 WHIP.

Gonzalez was removed from Sunday's game against the Cubs with an apparent injury, James Fegan of The Athletic reports.

EDGE Analysis

Gonzalez appeared to be in pain after throwing a curveball in the top of the seventh inning during the regular-season finale, and he was removed immediately after. The exact nature and severity of the injury aren't yet known.

Gonzalez (1-2) recorded an out prior to allowing a solo home run in the White Sox' 3-2 loss to the Indians on Wednesday night.

EDGE Analysis

Operating out of the bullpen after returning from a groin injury, Gonzalez had yet to allow a run through 5.1 innings of work. That changed on Wednesday, with Jordan Luplow mashing one into the left-field bleachers. Gonzales ups his ERA to 4.50, but is a candidate to see a lot of work in the finals days of the season as the White Sox look to rest their key arms.

Gonzalez allowed one unearned run on one hit and three walks whiles striking out two over two innings in Wednesday's 8-1 win over the Pirates.

EDGE Analysis

Gonzalez made his first appearance since being activated from the injured list. He's expected to serve as a multi-inning reliever, although he could spot start. The White Sox are skipping Dallas Keuchel (back) this turn through the rotation, so they will need a fill-in starter this weekend against Detroit.

Gonzalez (groin) was activated from the injured list Tuesday.

EDGE Analysis

Gonzalez had been out since late August with a strained groin. He's made four starts and a pair of relief appearances so far this season, posting an unremarkable 5.11 ERA along with a 1.86 WHIP. It's not yet clear what his role will be upon his return. Zack Burdi was optioned in a corresponding move.

Gonzalez (groin) is expected to throw this weekend at Chicago's alternate site, Scott Merkin of MLB.com reports.

EDGE Analysis

Gonzalez has been on the injured list retroactive to Aug. 27. If he makes it back up to the majors before the end of the season, Gonzalez is expected to pitch as a reliever capable of throwing multiple innings.
