White Sox Acquire Cam Booser

By Nick Deeds | December 21, 2024 at 6:06pm CDT

6:06pm: The trade has now been announced, with Booser headed to Chicago in exchange for right-hander Yhoiker Fajardo. To make room for Booser on the club’s 40-man roster, the White Sox designated Corey Julks for assignment. Fajardo, 18, posted a 3.91 ERA in 13 starts during the Dominican Summer League this year. Julks, 28, hit .214/.275/.306 in 66 games with the White Sox this year.

4:01pm: The White Sox and Red Sox are in agreement on a deal that will send left-hander Cam Booser to Chicago, according to a report from Robert Murray of Fansided. The return headed to Boston in exchange for Booser’s services is not yet clear, though James Fegan of Sox Machine reports that a minor league player is the return and Chris Cotillo of MassLive further clarifies that the return is expected to be a minor league pitcher.

Booser, 33 in May, made his big league debut with the Red Sox back in April. After kicking off his professional career with the Twins in 2013, he climbed the minor league ladder but hit a wall in High-A during the 2017 season. He eventually resurfaced in independent ball in 2021 and bounced between indy ball and the minor leagues for the Diamondbacks until joining the Red Sox organization for the 2023 season.

Once he finally made his big league debut last year, he pitched quite well for the club with a 3.38 ERA in 42 2/3 innings of work with a 23.5% strikeout rate with an 8.7% walk rate. That was good for a solid 3.80 FIP, though an elevated 80% strand rate and a low 8.3% home-run-to-fly-ball ratio suggest the possibility of some regression in Booser’s profile as represented by a 3.92 SIERA and a 4.40 xFIP. Despite his somewhat questionable peripherals and an unusual path to the big leagues, however, Booser profiled as a quality middle relief option from the left side.

With Aroldis Chapman and Justin Wilson already added to the bullpen from the left side in Boston and Brennan Bernadino in the fold as a more established lefty option as well, Booser had become somewhat expendable for the Red Sox. That’s evidently led him to join the White Sox bullpen, where he joins former Yankees reliever Ron Marinaccio among external additions this winter. Booser figures to be much higher on the lefty relief depth chart in Chicago than he would’ve been in Boston, as he trades the competition of established veterans like Chapman and Wilson out for less established arms like Jared Shuster and Fraser Ellard.

Red Sox Select Zach Penrod, Designate Tyler Heineman

By Mark Polishuk | September 14, 2024 at 9:47am CDT

The Red Sox announced five transactions this morning, including the news that left-hander Zach Penrod’s contract has been selected to the big league roster. Catcher Tyler Heineman was designated for assignment to open up a spot on the 40-man roster, and left-hander Cam Booser and right-hander Zack Kelly were both optioned to Triple-A Worcester to create space on the active roster. Boston also called up southpaw Bailey Horn from Triple-A. Julian McWilliams of the Boston Globe (X link) was the first to report on the Penrod, Booser, and Horn transactions, while MassLive.com’s Chris Cotillo (via X) reported yesterday that Kelly was being optioned.

Kelly and Booser were two of six pitchers used by the Red Sox in Friday’s 5-4 loss to the Yankees, so today’s moves brings some fresh arms into Boston’s relief corps. For Penrod, he is now on the verge of his Major League debut, making quite a culmination of a six-year pro career that began as an undrafted free agent.

Penrod pitched briefly with the Rangers’ rookie league club in 2018 but he then spent two years on the sidelines due to both a Tommy John surgery and the canceled 2020 minor league season. The southpaw returned to pitch in the independent Pioneer League from 2021-23, and this performance caught the eye of Red Sox scouts and led to a minor league deal partway through the 2023 season. This year, Penrod has a 4.16 ERA over 62 2/3 combined innings at Double-A and Triple-A ball, as well as a huge 34.8% strikeout rate.

There is a pretty wide variance in those minor league numbers, as Penrod posted a 2.80 ERA in 35 1/3 Double-A innings and a much heftier 5.93 ERA in 27 1/3 frames in Worcester. Control has been a bit of a question mark for Penrod throughout his career, and his walk rate also spiked up to 16.1% in Triple-A after a more palatable 9.1% number in Double-A action.

Still, the strikeouts are playing at both levels, and Penrod’s upper-90s fastball makes him an interesting bullpen weapon for the Red Sox to explore. Penrod has mostly started throughout his pro career but worked out of the pen for 10 of his 15 appearances in Worcester, so Boston figures to use him in a long relief role here at the tail end of the 2024 season. As Alex Speier of the Boston Globe explored back in May, Penrod’s development of a slider as a third pitch after his fastball and changeup could help him carve out a path as a starter, but the 27-year-old is surely pleased to work in the majors in any capacity.

The Red Sox acquired Heineman in a trade with the Mets back in February, and he has spent almost the entire season in the minors save for two games at the MLB level. Connor Wong and Reese McGuire handled most of the catching duties for the Sox this season, and after Danny Jansen was acquired at the trade deadline, McGuire was outrighed to Triple-A and Heinemen was pushed even further down the depth chart.

With his two appearances in a Red Sox uniform, Heineman has now now suited up for five different teams at the big league level over his five seasons in the Show, and he has also been organizational depth for six other franchises. Heineman has hit .216/.297/.280 over 286 career plate appearances, with 174 of those PA coming as a member of the Pirates and Blue Jays in 2022. Because Heineman has been outrighted before, he has the ability to elect free agency and reject an outright assignment from Boston if he clears DFA waivers.

Red Sox Place Tyler O’Neill On 10-Day IL, Activate Chris Martin

By Nick Deeds | August 7, 2024 at 7:31pm CDT

The Red Sox announced a series of roster moves this evening, headlined by the club placing outfielder Tyler O’Neill on the 10-day injured list due to a left leg infection. The move is retroactive to August 4. Replacing O’Neill on the active roster is infielder Enmanuel Valdez, who has been recalled to the big league roster, and the Red Sox also activated right-hander Chris Martin from the 15-day IL. Lefty Cam Booser was optioned to Triple-A to make room for Martin.

O’Neill, 29, was acquired from the Cardinals over the offseason and has enjoyed an excellent campaign during his first season in Boston. In 342 trips to the plate this season, the 29-year-old has slashed an excellent .268/.357/.544 (142 wRC+) with 16 doubles and 22 homers. While he’s striking out at a hefty 31.9% clip, he’s paired those strong power numbers with a solid 11.1% walk rate that has given him a more well-rounded profile than he flashed in his career-best 2021 campaign when he crushed 34 homers and posted a 143 wRC+ but walked at a clip of just 7.1%.

The slugger’s performance this year seems likely to line the pending free agent up for hefty raise in free agency this winter, although one red flag for O’Neill has been his frequent trips to the shelf. After suffering hamstring, back, foot, and shoulder injuries during his final two seasons with St. Louis, he’s now made three trips to the shelf with the Red Sox this year: once for a concussion in April, once due to knee inflammation in May, and now today’s most recent ailment that manager Alex Cora described to reporters (including Pete Abraham of The Boston Globe) as a worsening infection on his left leg that has caused swelling.

The silver lining in O’Neill’s repeated trips to the IL this year is that they’ve all been fairly short-lived, and Cora indicated that this one should be more of the same as he’s likely to be activated once eligible to return next week. In the meantime, the Red Sox figure to turn to some combination of Jarren Duran, Wilyer Abreu, Ceddanne Rafaela, and Rob Refsnyder in the outfield. With Rafaela frequenting the outfield in recent days, Valdez should help to shore up the club’s middle infield mix alongside David Hamilton, Nick Sogard, and Romy Gonzalez. The 25-year-old enjoyed a strong rookie season in 2023 but has taken a step back this year with a .226/.282/.402 slash line in 182 trips to the plate at the big league level.

As for Martin, the right-hander’s return to action is welcome news for a beleaguered Red Sox bullpen that has been second-worst in the majors since the start of July, ahead of only the White Sox. The 38-year-old veteran sports a solid 3.42 ERA with a matching 3.40 FIP in 26 1/3 innings of work this year and is coming off an even better season in 2023 where he dominated to the tune of an eye-popping 1.05 ERA in 55 appearances. Adding Martin to the late-inning mix to be the primary set-up man for closer Kenley Jansen should further shore up a bullpen that got reinforcements in the form of Lucas Sims and Luis Garcia prior to the trade deadline. He’ll take the roster spot of Booser, who heads to Triple-A to become the club’s top depth option with an excellent 2.77 ERA and 2.99 FIP in 39 innings of work this year.

While the bullpen will hopefully be revitalized by the return of Martin, Cora suggested to reporters today (including Abraham) that the Red Sox intend to skip right-hander Nick Pivetta’s next start. While the veteran righty doesn’t appear to be injured, Cora indicated that he’s “not responding well” coming out of his last start and that the club had some concerns about a dip in his velocity. With a day off scheduled tomorrow, the Red Sox will be able to utilize the rest of their rotation on regular rest without needing to call up another arm to take the spot on Pivetta. The righty has a middling 4.44 ERA through 18 starts this year thanks primarily due to a trio of brutal outings his last three times out that have seen him surrender 13 runs (12 earned) in 14 innings of work while serving up six home runs.

Red Sox Outright Naoyuki Uwasawa

By Darragh McDonald | July 13, 2024 at 6:33pm CDT

TODAY: The Red Sox outrighted Uwasawa to Triple-A after he cleared waivers, according to Pete Abraham of the Boston Globe (X link).

JULY 9: The Red Sox have selected the contract of right-hander Trey Wingenter, per Chris Cotillo of MassLive on X. Wingenter was acquired from the Tigers on the weekend and had an assignment clause in his contract, meaning he needed to be added to the roster. To make room for him, the club has optioned left-hander Cam Booser and designated right-hander Naoyuki Uwasawa for assignment. They also optioned infielder/outfielder Enmanuel Valdéz and recalled infielder/outfielder Jamie Westbrook.

Uwasawa, 30, had spent his entire career with the Nippon Ham Fighters of Japan’s Nippon Professional Baseball until signing a minor league deal with the Rays over the winter. He wasn’t going to make the Rays’ roster out of camp but had an upward mobility clause in his deal, meaning he would have to be traded if any other club was willing to give him a spot. The Red Sox were interested and sent cash to the Rays to get a deal done, though they have largely kept Uwasawa on optional assignment.

The righty has made two appearances at the big league level this year, with one earned run allowed in four innings. He’s mostly been serving in a swing role at the Triple-A level, with fairly uninspiring results there. He has a 6.54 ERA in 42 2/3 innings over 13 appearances, including six starts. He only struck out 18.5% of opponents while giving out walks at a 12.3% clip. The club tried moving him to a relief role, with his six most recent appearances coming out of the bullpen, but without a significant improvement. He had a 6.32 ERA in his first seven appearances this year and a 7.15 ERA in the last six.

The Sox will now have a week to trade Uwasawa or pass him through waivers. Since the waiver process takes 48 hours, any potential deal would have to come together in the next five days. His results this year have been poor but teams could perhaps be interested based on his NPB track record. He tossed over 1,000 innings in that league with a 3.19 ERA before making the move to North American ball, though that came despite a fairly tepid 19.7% strikeout rate. The lack of velocity/strikeout stuff was the biggest knock on him before crossing the Pacific and those concerns seem to have been borne out so far.

AL East Notes: Martin, Torres, Garcia

By Mark Polishuk | July 6, 2024 at 9:28am CDT

The Red Sox placed Chris Martin on the 15-day injured list yesterday (retroactive to July 4) and called up left-hander Cam Booser from Triple-A to fill Martin’s spot in the bullpen. Martin is suffering from right elbow inflammation, and manager Alex Cora told the Boston Globe’s Julian McWilliams and other reporters that there isn’t yet any plan for Martin to undergo any testing. The hope is that the 15-day rest (which encompasses the All-Star break) is all it takes for Martin to feel better and return to the mound.

This is the second time Martin has been on the IL this week, as he also missed two weeks in June dealing with anxiety. Over 26 1/3 innings this season, the right-hander has a strong 27.9% strikeout rate and an elite 1.9% walk rate, while posting an 3.42 ERA that has been inflated by some troubles with home runs. Martin’s SIERA is 2.44, by comparison, and his .313 BABIP reflects a bit of bad batted-ball luck. Despite the time spent on the injured list, Martin still leads the Red Sox with 10 holds and is the club’s top set-up option for closer Kenley Jansen.

Red Sox Designate Joe Jacques For Assignment

By Darragh McDonald | April 19, 2024 at 2:10pm CDT

The Red Sox have designated left-hander Joe Jacques for assignment, with Chris Cotillo of MassLive among those to relay the news. His roster spot will go to Cam Booser, whose promotion was reported yesterday.

Jacques, 29, was first added to Boston’s roster last year. To this point, he has thrown 28 1/3 innings in the majors with a 5.08 earned run average. His 16.8% strikeout rate is subpar but his 7.6% walk rate is solid and his 64.8% ground ball rate is very strong.

His production in the minors has been fairly similar, though with a few more punchouts. He tossed 39 Triple-A innings last year with a 2.54 ERA, keeping the ball on the ground at a 60.4% rate. He struck out 21.6% of batters faced while walking 8%.

The Sox seemingly prefer to get a look at the fireballing, late-blooming Booser, as opposed to the soft-tossing Jacques. The latter throws his sinker, which averages just over 90 miles per hour, roughly two thirds of the time. Booser, meanwhile, can get his fastball up into the high 90s.

Boston will now have a week to trade Jacques or pass him through waivers. There’s often demand for lefty relief and Jacques still has options, meaning he wouldn’t need an active roster spot if any team were to acquire him.

Red Sox To Select Cam Booser

By Darragh McDonald | April 18, 2024 at 5:35pm CDT

Left-hander Cam Booser is joining the Red Sox in Pittsburgh tomorrow, per Ian Browne of MLB.com. The lefty will be added to the club’s 40-man roster, per Andrew Parker of Beyond the Monster, who adds that lefty Joe Jacques will be optioned to open a spot on the active roster. The Sox will also need to open a 40-man roster spot but could do so easily by transferring Trevor Story to the 60-day injured list, since he will miss the rest of the year due to shoulder surgery.

Booser will crack a major league roster for the first time at an usually old age, as his 32nd birthday is just a few weeks away. It’s a testament to his determination that he will make it to the show after all these years, as he made his minor league debut over a decade ago, playing Rookie ball in the Twins’ system in 2013. After a few years in the minors, he topped out at High-A in 2017, not pitching in any official capacity for the next few years.

He resurfaced with the Chicago Dogs, an indy ball team, in 2021. He tossed 23 1/3 innings with a 1.93 earned run average for the Dogs that year and showed enough promise to get a minor league deal with the Diamondbacks for 2022. He tossed 25 innings in Double-A but struggled with a 6.48 ERA and got released. He then joined the Lancaster Barnstormers, another indy ball club, and tossed 11 2/3 innings with a 4.63 ERA.

He was able to secure himself a minor league contract with the Red Sox for 2023 and made 48 Triple-A appearances last year. He had a 4.99 ERA in his 57 2/3 innings, striking out 26.7% of batters faced while walking 9.7%. He received an invite to major league camp in 2024 and seemed to impress manager Álex Cora, as the skipper mentioned him to reporters last month, highlighting his high-90s fastball and ability to throw offspeed pitches in the zone.

It was around that same time during Spring Training that Ian Browne of MLB.com profiled the lefty. Booser apparently retired at the end of the 2017 season following several injuries, a marijuana suspension and “self-admitted attitude problems.” He then turned his attention to a carpentry career but stumbled back onto the mound by doing lessons with kids and rediscovering his past form.

“After the kiddos would leave, I would stay in the dark and throw into a net by myself for a couple of months. And through that process, I found out that my arm felt better than it ever had with that time off. One day, I got on the mound and my fastball was pretty good, 97-98 [mph]. So we figured, ‘Let’s give it a shot.’ I met with a trainer back home the next day and went out there to [independent] ball in 2021, and it’s been a great journey ever since.”

Booser didn’t break camp with the Sox but reported to Triple-A and has thrown 6 2/3 innings over four appearances this year, allowing two earned runs while striking out 15 opponents against just one walk. Though he obviously didn’t take the traditional path, Booser has found his way to the big leagues in amazingly unique fashion. The Sox have Brennan Bernardino and Joely Rodríguez in their bullpen but Booser will give them a third southpaw option.

Red Sox Notes: Grissom, Winckowski, Rotation, Booser

By Leo Morgenstern | March 17, 2024 at 2:31pm CDT

Vaughn Grissom was already questionable for Opening Day, but Alex Cora offered an update this morning on the timeline for his second baseman’s return. “We’re talking mid-April probably, [or] late April,” the Red Sox manager told members of the media, including Ian Browne of MLB.com. Grissom has not yet appeared in a Grapefruit League game; he has been nursing a groin strain all spring.

Boston traded for Grissom in December, sending Chris Sale (and $17MM) to Atlanta to complete the exchange. The Red Sox were counting on the 23-year-old to be their everyday second baseman in 2024. Barring a significant setback, he can still fill that role, and if he returns in mid-April, he might only miss 15-20 games.

When news of Grissom’s injury first broke, Cora told Pete Abraham of The Boston Globe that Enmanuel Valdez would fill in at second base. Valdez started 44 games at the keystone for the Red Sox last season. He slashed a perfectly respectable .266/.311/.453 in 149 plate appearances, with eight doubles and six home runs. However, he took nearly 90% of his plate appearances with the platoon advantage and went 2-for-14 against left-handed pitching. Thus, Pablo Reyes is likely to grab some starts at second with a southpaw on the mound.

In pitching news from Red Sox camp, Cora told reporters (including Sean McAdam of MassLive) that Josh Winckowski is no longer in the running for the Opening Day rotation, and he will likely move to the bullpen to begin the season. As Browne points out, that leaves Tanner Houck, Garrett Whitlock, and Cooper Criswell competing for the final two jobs on Boston’s starting staff. Brayan Bello, Nick Pivetta, and Kutter Crawford will hold down the top three spots.

Winckowski pitched well out of the bullpen last season, posting a 2.88 ERA in 84 1/3 innings of work. His 3.84 SIERA and 3.82 xERA were more good than great, but there is no denying he was an effective reliever, especially against left-handed opponents. The same cannot be said for his time as a starting pitcher the year before. Over 70 1/3 innings, Winckowski pitched to a 5.89 ERA, 4.84 xERA, and 4.82 SIERA, striking out a mere 44 batters while walking 27. Nonetheless, the 25-year-old told Rob Bradford of WEEI that he still considers himself a starting pitcher.

While Cora suggested Winckowski would likely fill a multi-inning role at the MLB level, he didn’t completely shut down the possibility that the righty could begin the season as a starter at Triple-A (per McAdam). “We still have got decisions to make,” said the skipper. “We’ll transition him now to the bullpen… and we’ll make decisions after that.”

Out of Houck, Whitlock, and Criswell, a trio of tall, 27-year-old right-handers, it seems like the former two have the edge over the latter. Houck and Whitlock have significantly more big league experience, and both were serviceable out of the rotation for Boston in 2023. Houck has a career 3.86 ERA in 252 innings, while Whitlock has a career 3.51 in 223 1/3 frames. Criswell has pitched well this spring, but it would be hard to argue he has done enough to edge out either of his more proven teammates.

Turning back to the bullpen, Cora mentioned an interesting name to Christopher Smith of MassLive: Cam Booser. Booser will turn 32 in May. He has spent time in the Twins, Diamondbacks, and Red Sox organizationx. He has never been selected to a 40-man roster, let alone pitched in the major leagues. Yet Booser was the first name the manager mentioned, pointing out his upper-90s fastball velocity and the way he has landed “offspeed pitches for strikes.”

That said, Cora was also clear to emphasize the value of experience. Brennan Bernardino, who already has a spot on the 40-man roster, made 55 appearances last year with a 3.20 ERA. Joely Rodríguez, a non-roster invitee, has pitched in 168 games over six big league seasons. Chris Murphy, another 40-man arm, found moderate success as a multi-inning reliever last season, tossing 47 2/3 frames over 20 appearances with the Red Sox. Cora brought up all three of their names in the same discussion, and it’s hard to imagine Booser beating out any of them for a spot on the Opening Day roster.

Still, it’s becoming clear that Booser is a name to keep an eye on this season. He has given up just two runs in eight innings this spring, striking out eight and walking none.
