Manager Joe Girardi said Stock is experiencing forearm tightness, Matt Gelb of The Athletic reports.

EDGE Analysis

Girardi added that Stock could be dealing with a flexor tendon issue, though the team won't know until he undergoes additional testing. The Phillies will certainly proceed cautiously with Stock, as forearm tightness can often be the precursor to a more serious injury.

Stock (biceps) was claimed off waivers by the Phillies on Thursday, Kevin Acee of The San Diego Union-Tribune reports.

EDGE Analysis

The 29-year-old missed the second half of 2019 with a strained biceps after posting a 10.13 ERA over 10.2 innings for the Padres. He'll now join the Phillies' pitching staff, where he'll likely serve as a middle reliever as he did in San Diego.

Stock (biceps) was transferred to the 60-day injured list Sunday.

EDGE Analysis

Stock began a two-game rehab stint in mid-August as he attempted to return from a right biceps strain, but he hasn't seen game action in a couple weeks. The move to the 60-day IL doesn't necessarily impact the 29-year-old return timeline since he's eligible to be activated later in the week, but it's unclear if he suffered a setback.

Stock (biceps) began a rehab assignment Saturday with the Padres' rookie-level Arizona League affiliate, striking out two in a perfect inning in his appearance.

EDGE Analysis

Stock has been on the shelf since July 2 with a strained biceps, so he'll presumably need a few more outings in the minors before the Padres feel comfortable activating him from the 10-day injured list. Once reinstated, the right-hander will likely fill a low-leverage role out of the San Diego bullpen after being roughed up for 12 runs on 14 hits and eight walks in 10.2 innings in his 10 appearances with the big club prior to landing on the IL.

Stock landed on the 10-day injured list Thursday with a right bicep strain.

EDGE Analysis

The injury perhaps explains Stock's recent struggles, as he allowed six runs in 3.1 innings of work over his last two appearances. It's not clear how much time he's expected to miss.

Stock was recalled from Triple-A El Paso on Saturday.

EDGE Analysis

Stock made the Opening Day roster and struggled with six runs allowed in seven games and has not appeared in the majors since mid-April. The 29-year-old was a solid bullpen piece for San Diego last season with a 2.50 ERA, 1.26 WHIP and 38:13 K:BB across 39.2 innings.

Stock was optioned to Triple-A El Paso on Thursday.

EDGE Analysis

Stock failed to make an appearance during his most recent stint with the Padres, which lasted just one day. The right-hander was shipped to the minors to free up a roster spot for Thursday's starter, Matt Strahm, who was activated from the injured list.

Stock has been called up from Triple-A El Paso, Kevin Acee of The San Diego Union-Tribune reports.

EDGE Analysis

The Padres optioned Chris Paddack to High-A Lake Elsinore for rest purposes Wednesday, so Stock has been recalled in the corresponding move. The right-hander gave up six earned runs in six big-league innings this season before getting sent down in April.

The Padres optioned Stock to Triple-A El Paso on Sunday.

EDGE Analysis

San Diego will swap out Stock and Gerardo Reyes ahead of Sunday's series finale against the Diamondbacks in exchange for a pair of fresh relief arms in Phil Maton and Luis Perdomo. Stock surrendered runs in three of his most recent four appearances, prompting the demotion.

Stock struck out three in his 1.2 innings of scoreless relief work in the Padres' 10-3 loss against the Diamondbacks on Monday.

EDGE Analysis

It wasn't of any consequence in a lopsided defeat for the Padres, but Stock's performance was notable as he punched out three batters in a dominant ninth inning, needing just 12 pitches to do so. His fastball topped out at a blistering 100.6 miles per hour, and he also showcased a filthy 84-mph slider that demonstrated an impressive ability to change speeds and keep hitters off balance. The 29-year-old had a two-run hiccup in San Diego's March 30 game against the Giants, leaving his ERA at 6.75, but he posted a 2.56 mark over 39.2 innings last year, so if he can build on Monday's strong effort he could emerge as a solid contributor out of the Padres' bullpen.
