Red Sox add 12 non-roster invitees to spring training roster

The Red Sox have added 12 non-roster invitees to their spring training roster, the club announced earlier Saturday. The list of invitees consists of catcher Kole Cottam, infielders Triston Casas, Ryan Fitzgerald, David Hamilton, and Christian Koss, outfielder Franchy Cordero, and pitchers Chris Murphy, Durbin Feltman, Geoff Hartlieb, Brian Keller, Kaleb Ort, and John Schreiber.

Of these 12 minor-leaguers, four (Cordero, Hartlieb, Ort, and Schreiber) have already played in the majors while two (Hamilton and Keller) were acquired by Boston in some capacity this off-season.

Casas, 22, is undoubtedly the top prospect on this list. The left-handed hitting first baseman enters the 2022 season ranked by Baseball America as the No. 2 prospect in the Sox’ farm system behind only Marcelo Mayer. He is coming off a year in which he played for Double-A Portland, Triple-A Worcester, Team USA in the Summer Olympics, and the Scottsdale Scorpions of the Arizona Fall League.

Kottam and Koss played alongside Casas in Arizona last fall. Hamilton, meanwhile, suited up for the Salt River Rafters before he and fellow infielder Alex Binelas were traded from the Brewers to the Red Sox in December.

Among the pitching contingent, Murphy — a left-hander — and Feltman are the only two true prospects listed. That being said, Keller is certainly appealing seeing how he was scooped up from the Yankees in the minor-league phase of the Rule 5 Draft earlier this winter.

With the addition of these 12 players, the Red Sox now have 23 non-roster invitees on their spring training roster.

In Brian Keller, Red Sox add intriguing right-hander who found success out of the bullpen at Triple-A in 2021

The Red Sox have seemingly made an annual tradition of poaching prospects away from the Yankees in the minor-league phase of the Rule 5 Draft, and they did so again on Wednesday.

After selecting Royals left-hander Austin Lambright with their top pick, the Sox took Yankees right-hander Brian Keller with their second and final pick of the day.

Keller, 27, was originally selected by New York in the 39th round of the 2016 amateur draft out of the University of Wisconsin-Milwaukee. He has been used as both a starter and reliever throughout his professional career, but what he did out of the bullpen in 2021 stands out.

On the heels of the 2020 minor-league season getting cancelled due to the COVID-19 pandemic, Keller opened the 2021 campaign at Triple-A Scranton Wilkes-Barre as a member of the RailRiders’ starting rotation.

Out of the gate, Keller managed to keep runs off the board as evidenced by his 2.57 ERA through his first six starts. However, the Wisconsin native did so while walking as many batters as he struck out (21) and putting up a sky-high 6.36 FIP over 21 innings of work.

Beginning June 15, Keller was moved to Scranton’s bullpen on a near-full-time basis, as 15 of his 20 appearances from that point forward came as a reliever. As a result of that switch, the righty proceeded to post a 2.88 ERA and 3.16 FIP to go along with 44 strikeouts to 25 walks across 34 1/3 innings pitched to close out the season.

All told, Keller pitched to the tune of a 3.56 ERA, 1.88 WHIP, and .781 OPS against in 11 starts spanning 30 1/3 innings in 2021. Out of the bullpen, he produced a much lower 1.80 ERA, 1.28 WHIP, and .535 OPS against in 15 outings spanning 25 innings in 2021.

Not only that, but Keller’s strikeout rate increased from 19.7% as a starter to 34% as a reliever, while his walk rate slightly decreased from 19.7% as a starter to 16% as a reliever.

Per a recent report from Baseball America, Keller “gave up very little hard contact as a reliever” this year. He also “works up and down in the strike zone with a four-seam 91-95 mph fastball and a downer curveball, but he also can mix in a slider and cutter.”

Listed at 6-foot-3 and 210 pounds, Keller — who does not turn 28 until next June — was identified by Baseball America as someone who could provide a team with pitching depth given his experience in the minors.

Since Chaim Bloom took over as Boston’s chief baseball officer in 2019, the Red Sox have made a habit of combing the Yankees’ farm system for both major- and minor-league pitching depth.

In 2019, the Sox selected right-hander Raynel Espinal from the Yankees in the minor-league phase of the Rule 5 Draft and did the very same thing with fellow righty Kaleb Ort the following winter.

Both Espinal and Ort made their big-league debuts this past season, but Boston’s biggest discovery was undoubtedly Garrett Whitlock, who they poached from New York in the major-league portion of last year’s Rule 5 Draft.

On that note, it is worth mentioning that the big-league phase of the 2021 Rule 5 Draft has been postponed indefinitely while Major League Baseball remains in a lockout.
