Arrieta faced live batters Tuesday and threw a bullpen session Thursday, but he's yet to appear in a Cactus League game, Jordan Bastian of MLB.com reports.

EDGE Analysis

The Cubs are working on mechanical adjustments with Arrieta in camp, and it's not too surprising that they're easing the veteran into game action. At this point in his career, the key is staying healthy, especially after injuries slowed him down the past two seasons. Expect Arrieta to continue ramping up slowly during spring training, but the Cubs hope he can shoulder a decent load during the regular season, likely as the No. 2 starter behind Kyle Hendricks.

Arrieta is projected to be the Cubs' No. 2 starter behind Kyle Hendricks to begin the season, Jordan Bastian of MLB.com reports.

EDGE Analysis

The Cubs have lost Yu Darvish, Jon Lester and Jose Quintana this offseason, so there are certainly rotation spots to fill behind Hendricks. Alec Mills returns and will be in the mix along with Zach Davies, who came over from San Diego in the Darvish trade. Arrieta is penciled in as the No. 2 starter at this point, but things could certainly change during spring training.

Arrieta (hamstring) agreed to a one-year, $6 million contract with the Cubs on Friday, Robert Murray of FanSided.com reports.

EDGE Analysis

Arrieta spent the past three seasons with the Phillies, but he'll now return to the Cubs, where he pitched well across more than four seasons and won the Cy Young Award in 2015. He was less effective in Philadelphia while battling serious injuries, and he missed the final few weeks of the regular season in 2020 due to a right hamstring strain. However, the 34-year-old should be healthy heading into spring training in 2021 and should take on a prominent role in the Cubs' rotation following the offseason departures of Yu Darvish and Jon Lester.

Arrieta (hamstring) played catch in the outfield Sunday, Meghan Montemurro of The Athletic reports.

EDGE Analysis

While the Phillies aren't shutting Arrieta down due to the right hamstring strain he suffered Sept. 15, the right-hander isn't expected to be ready for game action before the regular season comes to an end in one week. Instead, the Phillies are turning their focus to getting Arrieta back at some point during the postseason, should the team qualify. Arrieta will wrap up the regular season with a 5.08 ERA and 1.51 WHIP, his worst marks in both categories since his time with the Orioles early in the previous decade.

Arrieta (hamstring) won't pitch again during the regular season, Matt Gelb of The Athletic reports.

EDGE Analysis

Arrieta was placed on the injured list with a Grade 1 hamstring strain Wednesday, and manager Joe Girardi confirmed Thursday that he'll be sidelined for the remainder of the season. Girardi was hopeful that the right-hander could return for a postseason run if the Phillies qualify.

Arrieta was placed on the 10-day injured list with a right hamstring strain Wednesday.

EDGE Analysis

Arrieta sustained a Grade 1 hamstring strain during his start Tuesday, and he'll be sidelined at least 10 days. The right-hander underwent an MRI on Wednesday, the results of which aren't yet known. With just under two weeks remaining in the regular season, Arrieta will likely be unavailable for the remainder of the year. The Phillies haven't announced who will take Arrieta's place in the starting rotation.

Phillies manager Joe Girardi said Arrieta (hamstring) will undergo an MRI on Wednesday, Matt Breen of The Philadelphia Inquirer reports.

EDGE Analysis

The Phillies believe Arrieta sustained a Grade 1 right hamstring strain in his start Tuesday, but he'll be sent in for further tests as the team looks to confirm the extent of his injury. While a Grade 1 strain likely wouldn't end Arrieta's season, he may not be able to shake off the injury before his next turn in the rotation comes up Sunday against the Blue Jays.

Arrieta said he sustained a Grade 1 hamstring strain during Tuesday's win over the Mets, Todd Zolecki of MLB.com reports.

EDGE Analysis

The 34-year-old doesn't believe it's a serious injury, but it's a tight time frame with less than two weeks remaining in the regular season. Arrieta missed 17 days after suffering a similar injury in 2017, and he would need an even faster recovery this time around to have even a slight chance of pitching again in the regular season. The veteran right-hander's status should be updated as he continues to be evaluated over the next couple days.

Arrieta left Tuesday's start against the Mets with an apparent right hamstring injury, Meghan Montemurro of The Athletic reports.

EDGE Analysis

The veteran right-hander hit Andres Gimenez with a pitch during the sixth inning and immediately clutched at what appeared to be his right hamstring, and he walked off the field with a significant limp. The severity of the injury remains unclear, but it's potentially a major loss for the Phillies with Spencer Howard (shoulder) on the injured list and Zack Wheeler (finger) also banged up. Arrieta exited Tuesday's contest in line for the win after allowing one run on eight hits with four strikeouts and one walk over 5.1 innings.

Arrieta pitched 5.2 innings against the Marlins on Thursday, allowing three runs on five hits and four walks while striking out three. He did not factor in the decision.

EDGE Analysis

It was an uneven performance for the veteran starter, who threw only 60 of 106 pitches for strikes and tied a season high with four walks but nearly held on long enough to notch a quality start. Arrieta yielded single runs in the first, third and fourth frames but settled down to retire five of the final seven batters he faced. He departed with a chance to pick up the win before Philadelphia's bullpen collapsed in the late innings and allowed Miami to complete a comeback victory. Arrieta will carry a 5.54 ERA into his next scheduled start, which is likely to take place at home against the Mets on Tuesday.
