Giles (forearm) announced Monday in a post on his personal Instagram account that he will undergo Tommy John surgery, Kaitlyn McGrath of The Athletic reports.

EDGE Analysis

Giles was already believed to be done for the season after being diagnosed with a right flexor strain following his Sept. 15 relief appearance. The outing was Giles' second since being reinstated from the 45-day injured list, as he had previously been shut down for most of the season with the same injury. After receiving feedback from doctors, Giles determined that surgery was his best option to address the nagging arm injury. He'll likely be sidelined for the entire 2021 season while recovering from surgery, though he should be fully cleared for the start of spring training in 2022. With Giles set to become an unrestricted free agent this winter, a team could look to bring the right-handed reliever aboard on a low-cost, two-year deal that would allow his rehab program to be monitored more closely.

Giles was placed on the 10-day injured list Wednesday with a right flexor strain, Ben Nicholson-Smith of Sportsnet.ca reports.

EDGE Analysis

Giles returned from the injured list Friday and made two relief appearances since he came back. However, manager Charlie Montoyo revealed Wednesday that he was put back on the injured list with a similar injury to what he dealt with earlier in the season. The right-hander underwent an MRI, but the results aren't yet known. "I wouldn't think he's coming back this year," Montoyo said.

Giles (forearm) was activated from the 45-day injured list Friday.

EDGE Analysis

Giles made just two appearances this season before landing on the injured list with a strained flexor mass in his right forearm in late July. He avoided surgery, however, and has been throwing for nearly a month. He's expected to make his first appearance or two in a lower-leverage role, as the lack of minor-league baseball this season has prevented him from making any rehab appearances, but he'll likely return to the closer position before the end of the year.

Blue Jays manager Charlie Montoyo said Wednesday that Giles (forearm) is close to a return from the 45-day injured list and will likely be used "before the ninth [inning]" initially once he's activated, Keegan Matheson of MLB.com reports.

EDGE Analysis

Since Giles has been on the shelf since late July with a strained right forearm, Montoyo is understandably reluctant to immediately thrust the 29-year-old into his familiar closer role right away while the 24-19 Blue Jays look to protect their positioning in the AL playoff race. So long as Giles looks good in his first appearance or two upon coming off the IL, however, he should move back ahead of Rafael Dolis and Anthony Bass in the pecking order for saves. Toronto hasn't yet put a firm target date on Giles' return from the IL, but his activation could come as soon as this weekend.

Giles (forearm) threw a live batting practice session that went well Tuesday, Arden Zwelling of Sportsnet.ca reports.

EDGE Analysis

Giles' throwing session marked the third time that he threw a live batting practice session over the past week, and he appeared to feel good after each one. The right-hander is eligible to return from the 45-day injured list as soon as Thursday and could do so if he continues to feel good in the coming days.

Giles (forearm) will throw another live batting practice session Tuesday, Hazel Mae of Sportsnet reports.

EDGE Analysis

Giles will be eligible to return from the 45-day injured list as soon as Thursday. The Blue Jays have yet to officially announce when he'll be back, but given that he's been throwing live batting practice for nearly a week, it doesn't seem as though he's very far off.

Giles (forearm) was transferred to the Blue Jays' 45-day injured list Saturday, Mike Wilner of Sportsnet 590 The Fan reports.

EDGE Analysis

Giles' move to the 45-day IL is simply procedural as he'll still be eligible to return as early as Sept. 10. The right-hander has made good progress while recovering from a strained flexor mass in his right forearm, although a specific timetable for his return still hasn't been established.

Giles (forearm) felt good after a live batting practice session Tuesday and will throw another similar session Saturday, Scott Mitchell of TSN.ca reports.

EDGE Analysis

Giles continues to make good progress as he works his way back from the strained flexor mass in his right forearm that has kept him out since late July. His target return date remains unclear, but he appears to have a very good shot to make it back before the end of the year, barring setbacks.

Giles (forearm) will throw a 20-pitch live batting practice session Tuesday, Kaitlyn McGrath of The Athletic reports.

EDGE Analysis

Giles has now been out for over a month with a strained flexor mass in his right forearm, but he continues to make good progress towards his return. It remains to be seen how many more times he'll have to throw before the Blue Jays feel ready to activate him, but when he does eventually return, he should reclaim his closer role.

Giles (forearm) is ready to advance to live batting practice, Kaitlyn McGrath of The Athletic reports.

EDGE Analysis

He threw a side session Friday that went well, with Giles reporting feeling good physically, so the next step will be to face live hitters. The Jays' bullpen has been solid in the late innings, with Jordan Romano and Anthony Bass both pitching well of late. However, if Giles gets back to normal physically, he will likely take back the ninth inning duties.
