6 Red Sox pitchers who could make a surprise impact in 2023
The Boston Red Sox had a busy off-season, signing closer Kenley Jansen (who has the 8th most saves of any player in MLB history with 391) and set-up man Chris Martin (3.05 ERA in 2022; 3.84 career ERA) to solidify a bullpen that was 2nd worst in the American League in 2022 (trailing only the Kansas City Royals).
Richard Bleier and Joely Rodríguez join Jansen and Martin as the other key additions to the Red Sox bullpen entering 2023; the team also has Tanner Houck, John Schreiber, and Ryan Brasier returning from last year.
Red Sox added notable pitchers this off-season, but others might make surprise impact in 2023
The Red Sox also signed veteran pitcher Corey Kluber, who joins a crowded starting pitching depth chart which includes Chris Sale, James Paxton, Brayan Bello, Garrett Whitlock, and Nick Pivetta (and potentially Tanner Houck, if he is not used as a reliever).
If the team chooses to carry 5 starters and 8 relievers on the 26-man roster at the start of the season, the hurlers listed above (Jansen, Martin, Bleier, Rodríguez, Houck, Schreiber, Brasier, Sale, Paxton, Bello, Whitlock, Pivetta) would leave only 1 roster spot up for grabs.
But don't expect it to remain at only 1. Injuries are inevitable, and when they happen it presents an opportunity for someone unexpected to step up. In recent days, there have been several reports that Garrett Whitlock, Brayan Bello, and James Paxton could start the season on the injured list.
While none of the 3 are expected to miss significant time, it still presents an immediate test of the pitching depth the Red Sox have. It begs the question: who are the most likely candidates to make a surprise impact this season if/when they are called upon? Read on to find out.
Kutter Crawford: Crawford could make some starts or appear as a multi-inning reliever (or both) this season for the Red Sox
Kutter Crawford had mixed results last season for the Red Sox. Across 77.1 innings in 2022, Crawford posted an uninspiring 5.47 ERA and 1.42 WHIP.
While his stats last season indicate he had his fair share of struggles at the big-league level, Kutter Crawford also had some flashes of brilliance. He shined brightest when he recorded 6 consecutive strong starts against playoff teams (between July 4th and August 2nd).
In 34 innings pitched against the Rays (twice), Yankees, Jays, Guardians, and Astros during the above timeframe, Crawford surrendered only 9 runs (2.38 ERA); he scattered 27 hits yielded only 5 walks over this same stretch (0.94 WHIP), while striking out 32 batters.
Kutter Crawford certainly showed enough to give the Red Sox some hope he can make a positive impact on the big-league club in 2023. Whether he is featured as a starter, reliever, or both is still unknown; this decision may depend on the team's needs when they call upon him.
Zack Kelly: Kelly's fastball-changeup mix was effective in late-2022 and he will likely be a factor in the Red Sox bullpen this season
Zack Kelly made his major league debut with the Red Sox in August 2022 after spending most of the season with the WooSox. During his time with the team's AAA affiliate, he logged 49.2 innings and posted a 2.72 ERA, 1.19 WHIP, and .191 BAA.
In Kelly's first 12 big-league appearances, he held the opposing offense scoreless in 10 of them. In aggregate, Kelly had a 3.95 ERA in 13.2 innings with the Red Sox in 2022. His stats were skewed by a rough final outing off 2022 (5 hits and 3 runs allowed in 1 inning), but he proved during his time with the Red Sox that his stuff is effective at the highest level. And after taking a deeper dive into the metrics, it is clear he has elite potential.
It is also notable that Zack Kelly and Kutter Crawford offer the Red Sox some roster flexibility because of the options they carry going into 2023. Both carry multiple options remaining per Spotrac, while pitchers Bryan Mata and Wyatt Mills only have 1. With multiple options left, the team may feel more comfortable using one in 2023.
Wyatt Mills: Mills joined the Red Sox after an under-the-radar trade with the Royals, hoping for a Schreiber-like breakout season
When the Red Sox traded for Wyatt Mills, the subsequent move to make room on the 40-man roster was to designate veteran Eric Hosmer for assignment. At the time, there was far more emphasis placed on the departure of Hosmer than the addition of Mills.
The 2022 stats for Mills don't exactly jump off the page (29.1 IP, 4.60 ERA, 1.33 WHIP). The 28-year-old righty who throws from "down under" has made 39 career appearances across 2 big-league seasons with the Mariners and Royals.
Wyatt Mills' arm slot looks very familiar, too; it didn't take long for comparisons to be made to Red Sox reliever John Schreiber. The video overlay of the two guys throwing a pitch seems pretty convincing, but you can be the judge of that.
For the record, John Schreiber's career stats were unimpressive, just like Mills, entering the 2022 season (5.97 ERA in 31.2 innings). The Red Sox might just catch lightning in a bottle again in 2023 with Wyatt Mills. Only time wil tell.
Brandon Walter, Bryan Mata, Chris Murphy (and more): The youth movement has begun
As previously mentioned, there are some concerns about Red Sox starters (Whitlock, Bello, Paxton) potentially not being ready to pitch by Opening Day. If they start the season on the Injured List, the rotation will almost certainly feature Chris Sale, Corey Kluber, and Nick Pivetta.
That leaves the final 2 spots open for the following contenders: Tanner Houck, Kutter Crawford, Josh Winckowski, Brandon Walter, Bryan Mata, and Chris Murphy. Based strictly off MLB service time and prior big-league performances, Houck and Crawford would have the edge.
With that said, it feels like there is still an outside chance that a guy like Walter, Mata, or Murphy, with no prior MLB service time, forces the Red Sox organization's hand and earns a spot on the Opening Day roster.
It's only spring training, but so far these "kids" have shown that the youth movement in Boston is real and it has only just begun. And Josh Winckowski has also performed well, making the competition for a roster even more highly contested.
2023 Spring Training Stats
Bryan Mata (23 years old): 2.0 innings, 0 hits, 0 runs, 1 walk, 3 strikeouts
Brandon Walter (26 years old): 3.0 innings, 1 hit, 0 runs, 0 walks, 5 strikeouts
Chris Murphy (24 years old): 2.2 innings, 1 hit, 0 runs, 2 walks, 5 strikeouts
Josh Winckowski (24 years old): 5.0 innings, 3 hits, 0 runs, 3 walks, 7 strikeouts
Health setbacks are never desirable, but the Red Sox are faced with a "good problem" in the sense that they have plenty of promising, young pitchers who are hungry to prove they can succeed at the highest level.
Red Sox fans will likely get to see some pitchers with truly electric stuff make their mark during the 2023 season. Sit back, relax, and enjoy the show!
