Arrieta announced Monday on Barstool Sports' "Pardon My Take" podcast that he's decided to retire after a 12-year career in the big leagues, ESPN.com reports. "Well, I haven't signed the papers, man, but I'm done. It's time for me to step away from the game," Arrieta said. "At some point the uniform goes to somebody else and it's just my time, really."

EDGE Analysis

Arrieta's retirement comes as little surprise following a rough 2021 campaign with the Cubs and Padres in which he posted a 7.39 ERA and 1.77 WHIP across 24 starts. Though his performance had been steadily trending down since his first stint with the Cubs ended after the 2017 season, Arrieta was arguably MLB's top starting pitcher from 2014 through 2016. He threw two no-hitters during that stretch, took home the 2015 National League Cy Young Award after submitting a 1.77 ERA across 229 innings that season and earned his lone All-Star appearance in 2016 before he helped the Cubs end an 108-year championship drought that fall. Arrieta retires with a lifetime 115-93 record and 3.98 ERA over 285 appearances between the Orioles, Cubs, Phillies and Padres.

Arrieta (groin) was designated for assignment by the Padres on Tuesday.

EDGE Analysis

Arrieta exited Sunday's start against the Cardinals with a strained right groin, and he won't make another start for San Diego. The 35-year-old was picked up in mid-August after being let go by the Cubs, and he surrendered 15 runs on 18 hits in 12.1 innings across his four starts with the Padres while also spending some time on the injured list.

Arrieta was diagnosed with a right adductor strain after leaving Sunday's start against the Cardinals.

EDGE Analysis

The veteran right-hander recorded one out during the first inning before being lifted with the injury, and he was charged with five runs (four earned) on three hits and a walk. Arrieta missed some time a few weeks ago with a hamstring injury, and he's now managing the groin issue. It's unclear if the injury will affect his next turn through the rotation.

Arrieta exited Sunday's game against the Cardinals after a third of an inning with an apparent injury, Katie Woo of The Athletic reports.

EDGE Analysis

It's unclear what injury Arrieta is dealing with. He allowed five runs (four earned) on three hits and a walk while recording just one out. Arrieta should be considered day-to-day until further updates.

Arrieta (5-13) was tagged with the loss Tuesday against the Giants after allowing three runs on five hits and two walks while fanning three across 3.2 innings.

EDGE Analysis

Arrieta has had a woeful season and hasn't been able to turn things around since being acquired by the Padres last month. The veteran hurler has allowed at least three earned runs in each of his last five appearances dating back to his time with the Cubs as well, and he owns an 8.25 ERA through three outings with San Diego.

Arrieta went five innings in Friday's 6-3 loss to the Astros, allowing three runs on three hits and a walk with three strikeouts. He didn't factor into the decision.

EDGE Analysis

Making his second start with his new team after returning from injury, Arrieta was rolling early before surrendering a Carlos Correa home run that scored all three runs charged to Arrieta. It took the veteran righty just 64 pitches to make it through five frames and he was most likely pulled as a result of throwing only 11.1 big-league innings over the past month. He's slated to take the mound against the Dodgers on Friday for his next start.

Arrieta (hamstring) was reinstated from the 10-day injured list prior to Friday's start against the Astros, Jeff Sanders of The San Diego Union-Tribune reports.

EDGE Analysis

Arrieta suffered a hamstring strain in his Padres debut Aug. 18, but he'll be back in action following an absence of just over two weeks. The right-hander has struggled across his last five starts and has posted a 13.76 ERA and 2.71 WHIP in 17 innings.

Manager Jayce Tingler said he expects Arrieta (hamstring) to start Friday against the Astros, AJ Cassavell of MLB.com reports.

EDGE Analysis

It was previously reported that the veteran right-hander was expected to return from the injured list this weekend, and it appears he'll rejoin the rotation for Friday's series opener. Arrieta surrendered five runs over 3.1 innings during his Padres debut before exiting with the hamstring strain.

Arrieta (hamstring) is expected to be activated for this weekend's series versus Houston, Bob Nightengale of USA Today reports.

EDGE Analysis

Arrieta went down with a strained left hamstring during his first start with San Diego, but he has since been able to toss bullpen sessions and appears to be nearing a return. The veteran hurler has struggled with a 7.13 ERA and 1.78 WHIP across 89.2 innings -- mostly with the Cubs -- this season, but Padres manager Jayce Tingler said Monday that Arrieta is likely to come back as a starter despite a slew of upcoming team off days, per 97.3 The Fan.

Arrieta (hamstring) threw a bullpen session Saturday and could return to the Padres in early September, per MLB.com.

EDGE Analysis

The right-hander exited with a mild hamstring strain during his first start with San Diego on Aug. 18, but it appears that the injury won't keep him out of action for an extended period. However, Chris Paddack (oblique) is nearing a return to the rotation and the Padres have two off days both this week and next, so it's not certain that Arrieta will be needed as a starter when he's able to rejoin the club.
