Phelps (elbow) threw his first live batting practice Saturday, Mike Wilner of Sportsnet 590 The Fan reports.

EDGE Analysis

He underwent Tommy John surgery last March, so he is likely a month or two away from pitching in games. Nonetheless, it is good to see that he has not had any notable setbacks in his recovery.

Phelps (elbow) agreed to a one-year, $2.5 million contract with the Blue Jays on Thursday, Jeff Passan of ESPN.com reports.

EDGE Analysis

Phelps last appeared in the major leagues during the 2017 season, posting a 3.40 ERA with 62 punchouts over 55.2 frames as a relief pitcher across stops in Miami and Seattle. After undergoing Tommy John surgery in March of 2018, the Blue Jays are hopeful the right-hander will be ready in time for spring training and that he could possibly earn a spot in their bullpen. Phelps began a throwing program back in mid-August, although it's unclear as to how close he is to a full recovery.

Phelps (elbow) played catch for the first time Monday since undergoing Tommy John surgery, Greg Johns of MLB.com reports.

EDGE Analysis

Phelps had Tommy John surgery in March of 2018, but he's ready to resume throwing once again. He still has a long way to go until he can return to action, so he figures to remain on the shelf until at least May of 2019.

Phelps was shifted to the 60-day disabled list Friday, Shannon Drayer of 710 ESPN Seattle reports.

EDGE Analysis

Phelps was moved after the Mariners needed room for both Denard Span and Alex Colome following a trade with the Rays. He's expected to be on the shelf for the rest of the 2018 season and possibly a part of the 2019 campaign following Tommy John surgery in mid-March.

Phelps (elbow) was placed on the disabled list Wednesday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Phelps is set to miss the entire 2018 season and potentially the start of the 2019 campaign after undergoing Tommy John surgery earlier in the week.

Phelps (elbow) will undergo Tommy John surgery Monday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Phelps was diagnosed with a torn UCL and will undergo Tommy John surgery, Ryan Divish of The Seattle Times reports.

EDGE Analysis

This is a tough blow for the Mariners and Phelps, as the veteran reliever was expected to play a key role in the team's bullpen this season. The 31-year-old apparently suffered the injury during his outing against the Angels last week. Given Tommy John surgeries typically carry a 12-to-18 month recovery timeline, Phelps will likely open the 2019 season on the disabled list. This comes after he missed the final month of the 2017 season after undergoing elbow surgery to remove a bone spur. With Phelps unavailable, Juan Nicasio, Nick Vincent and James Pazos will likely be tasked with getting the ball to Edwin Diaz.

Phelps (elbow) threw one shutout inning and recorded one strikeout Saturday against the Angels.

EDGE Analysis

As expected, Phelps made his Cactus League debut Saturday. He was efficient during his brief appearance, as he needed just five pitches to get through the inning. This marked the first live game for Phelps since having a bone spur removed from his elbow in September, so the Mariners will likely be cautious with how they increase his level of activity.

Phelps (elbow) will make his Cactus League debut against the Angels on Saturday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Phelps said that his elbow is "feeling great" as he continues to work his way back from a procedure to remove a bone spur in his elbow in mid-September. He was able to toss a live bullpen session Tuesday without any issue and will likely be eased into game action throughout the spring.

Phelps (elbow) is threw a live bullpen session Tuesday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Phelps got through his live bullpen session with no issues, clearing the way for him to make his Cactus League debut later in the week. The Mariners are slow playing the 31-year-old reliever early on in camp after he missed the final month of the 2017 season due to an elbow injury that eventually required surgery, but he's nearly back to full health and should be ready to go by Opening Day barring any setbacks for the remainder of spring training.
