Stock was claimed off waivers by the Cubs on Wednesday.

EDGE Analysis

Stock was designated for assignment by the Red Sox last week, but he'll find a new spot on a 40-man roster heading into the 2021 campaign. The right-hander made 10 major-league appearances in 2020, logging a 4.73 ERA and 14:10 K:BB over 13.1 innings. Stock has an average fastball velocity of 96.8 mph, but he carries a 10.9 percent walk rate over three seasons in the majors.

The Red Sox designated Stock for assignment Wednesday.

EDGE Analysis

Boston cast Stock off the 40-man roster to create an opening for reliever Joel Payamps, who was claimed off waivers from Arizona. A hard-throwing right-hander, Stock has struggled to find the strike zone over parts of three seasons in the big leagues, walking 10.9 percent of the batters he's faced during his career.

Stock was optioned to the Red Sox's alternate training site Tuesday.

EDGE Analysis

Stock has had inconsistent results while serving out of the major-league bullpen this season, and he'll head back to the alternate training site with just under a week remaining in the regular season. He's posted a 4.73 ERA and 14:10 K:BB over 13.1 innings so far in 2020. Nick Pivetta was recalled ahead of his scheduled start Tuesday in a corresponding move.

Stock was recalled by the Red Sox on Thursday.

EDGE Analysis

Stock was sent down by the Red Sox on Saturday, but he'll return to the major-league bullpen after a short stay in Pawtucket. The right-hander hasn't been very effective this season with a 5.87 ERA and 2.61 WHIP over 7.2 innings during seven relief appearances.

Stock was optioned to Boston's alternate training site following Saturday's game.

EDGE Analysis

Lefty Matt Hall was summoned to replace Stock, who covered 1.2 total innings out of the bullpen Friday and Saturday. Overall, Stock has a 5.87 ERA and 2.61 WHIP in 7.2 innings -- not good at all, but he may very well be back later this year with the Red Sox lacking many viable alternatives.

Stock, along with Jeffery Springs, were recalled from the Red Sox's alternate training site Saturday to fill the vacant spots from the Brandon Workman and Heath Hembree trade, Chris Cotillo of The Springfield Republican reports.

EDGE Analysis

Stock has made just one appearance out of the bullpen this season, allowing an unearned run on two hits and three walks while also managing to strike out three in 1.1 innings. He figures to be a middle reliever for the Red Sox moving forward.

Stock was optioned to Boston's alternate camp Thursday, Ian Browne of MLB.com reports.

EDGE Analysis

This move frees up a roster spot for Thursday's starter, Kyle Hart, who was added to the roster in a corresponding move. Stock allowed an unearned run on two hits and three walks while striking out three batters in his lone appearance this season (1.1 innings).

Stock was recalled from the Red Sox's alternate training site Tuesday.

EDGE Analysis

Stock was claimed off waivers by Boston at the end of July but will join the active roster after Jeffrey Springs was optioned to alternate camp. Stock made 10 appearances in the majors with the Phillies last season, posting a 10.13 ERA and 2.06 WHIP over 10.2 innings. He should pitch mainly out of low-leverage situations with the Red Sox.

Stock was claimed off waivers by the Red Sox on Sunday and was optioned to the team's alternate training site.

EDGE Analysis

The veteran right-hander was designated for assignment by the Phillies on Thursday, and he now finds himself on the Red Sox's 40-man roster. Stock had a strong 2018 in San Diego with a 2.50 ERA and 1.26 WHIP in 32 appearances, but he struggled last season and allowed 12 runs over 10.2 big-league innings.

Stock was designated for assignment by the Phillies on Thursday.

EDGE Analysis

Stock failed to impress enough to win a bullpen spot this summer, so he'll be jettisoned from the roster to create space for Trevor Kelley and Ramon Rosso, whose contracts were selected after winning spots themselves. Stock owns a respectable 4.11 ERA in 50.1 career innings at the highest level, which could be enough for him to be an interesting option on waivers.
