Jackson announced Friday via his personal Instagram account that he has retired from professional baseball.

EDGE Analysis

Jackson's retirement came on his 39th birthday and 19 years after he made his big-league debut. The veteran right-hander went on to see action with an MLB-record 14 teams during his career, amassing a 107-133 record and 4.78 ERA across stops with the Dodgers, Rays, Tigers, Diamondbacks, White Sox, Cardinals, Nationals, Cubs, Atlanta, Marlins, Padres, Orioles, Athletics and Blue Jays. He made his only All-Star appearance with Detroit in 2009, tossed a no-hitter with Arizona in 2010 and won his lone World Series title with St. Louis in 2011.

The Diamondback released Jackson on Thursday, Andersen Pickard of MLBDailyDish.com reports.

EDGE Analysis

Jackson joined the Diamondbacks in camp as a non-roster invitee prior to the COVID-19 outbreak but was likely facing an uphill battle to claim an Opening Day roster spot anyway. With active rosters potentially expanded for the upcoming season, Jackson could end up finding a home somewhere as a bullpen arm despite an uninspiring 2019 season.

Jackson joined the Diamondbacks as a non-roster invitee on Monday, Evan Woodberry of MLive.com reports.

EDGE Analysis

The 36-year-old appears to face an uphill battle in his quest for an Opening Day roster spot. In 67.2 innings for the Blue Jays and Tigers last season, he struggled to a 9.58 ERA while striking out just 15.5 percent of opposing batters.

Jackson won't start Game 2 of Friday's doubleheader against the White Sox due to weather.

EDGE Analysis

Jackson was slated to toe the rubber for the nightcap, but rain has postponed the matchup. The Tigers will play a straight doubleheader Saturday and a single game Sunday, putting them at 161 games for the season.

Jackson will pitch out of the bullpen going forward, Chris McCosky of The Detroit News reports.

EDGE Analysis

The Tigers have little reason to give any more starts to a 36-year-old with a 9.70 ERA on the season. Tyler Alexander will take his place in the rotation for the final two weeks, though the Tigers do have a doubleheader coming up on the final Friday of the season, which could potentially mean one more opportunity for Jackson.

Jackson (3-10) gave up five earned runs on seven hits with five strikeouts and two walks over five innings as he took the loss Sunday afternoon to the Orioles.

EDGE Analysis

Jackson's struggles continued Sunday as he failed to eclipse the five-inning for the seventh consecutive outing. The right-hander has allowed at least four earned runs in each of his last six starts and has not registered a quality outing since August 9. His ERA has now ballooned to a 9.70 as he is scheduled to take the mound next against the White Sox on Saturday.

Jackson allowed six earned runs on six hits and one walk while striking out two across two innings Tuesday against the Yankees. He did not factor into the decision.

EDGE Analysis

Jackson survived the first inning by allowing only a solo home run to Brett Gardner. However, things broke open in the second frame, as he allowed four runners to reach base before retiring an out -- surrendering five runs in all. After allowing just three earned runs across 11.1 innings in his first two starts with the team, Jackson has now allowed four or more earned runs in five consecutive appearances. He's scheduled to take the ball next on Sunday against Baltimore.

Jackson (3-9) allowed four runs on nine hits across five innings to take the loss Wednesday against the Royals. He struck out three and walked one.

EDGE Analysis

Jackson pitched better than he did in his last start, when he allowed eight runs (six earned) in 2.1 innings against the Twins, but the veteran was still relatively ineffective. With a 9.16 ERA through 57 innings this year, Jackson is squarely off the fantasy radar heading into his next start against an imposing Yankees lineup on Tuesday.

Jackson (3-8) took the loss Friday as the Tigers were routed 13-5 by the Twins, surrendering eight runs (six earned) on seven hits and three walks over only 2.1 innings. He struck out one.

EDGE Analysis

Facing Minnesota for the second straight outing, the veteran needed 70 pitches (41 strikes) to record just seven outs, and the only bright spot in this latest disaster for Jackson is that he managed to keep the ball in the yard. He's now saddled with a 9.35 ERA and 39:25 K:BB through 52 innings on the year, and while his next turn in the rotation is set for Wednesday in Kansas City, it wouldn't be a surprise to see him bumped aside for a September callup.

Jackson (3-7) allowed six runs on seven hits over five innings to take the loss Saturday against the Twins. He walked two and struck out five.

EDGE Analysis

Jackson started the game by allowing a leadoff home run to Max Kepler and a walk to Jorge Polanco, but he settled down and was able to work pretty quickly through four innings with just the one run allowed. However, things fell apart in the fifth, as the veteran allowed five hits, including a two-out, three-run home run to Miguel Sano. Jackson's ERA is now sitting at an unsightly 8.70, making him incredibly hard to trust, and it's not a given the Tigers keep him in the rotation moving forward.
