White Sox Sign Juan Then To Minor League Deal

By Darragh McDonald | February 2, 2024 at 4:45pm CDT

The White Sox have signed right-hander Juan Then to a minor league deal, according to his transactions tracker at MLB.com. He’s been assigned to Triple-A Charlotte for now but could perhaps receive an invite to major league Spring Training.

Then (pronounced “Ten”) will be turning 24 on Wednesday, so it’s a bit of an early birthday present for him. The righty made his major league debut with the Mariners last year, getting into nine games and logging 11 innings, allowing six earned runs. He only struck out five opponents but also only gave out two walks, while 63.4% of the balls in play he allowed were on the ground. He was outrighted by the Mariners in August and was able to elect free agency at season’s end.

Originally an international signing of the Mariners, he was traded to the Yankees in 2017 for Nick Rumbelow but then came back to the M’s via the 2019 Edwin Encarnación trade. Primarily a starter in his earlier years, the Mariners added him to their 40-man roster in November of 2020 to keep him out of the Rule 5 draft. He then struggled in 2021 and was mostly injured in 2022. He was heading into his final option season last year, so the Mariners moved him to the bullpen.

In addition to the aforementioned major league work, he tossed 36 1/3 innings in the minors with an ERA of 8.92. That’s obviously an unpleasant number to look at, but it appears worse than it is. His .411 batting average on balls in play and 54.3% strand rate were both on the unfortunate side, which is why his FIP was more than three runs lower than his ERA at 5.87.

That FIP still isn’t terribly exciting, but Then is still quite young and he was considered the Mariners’ #17 prospect as recently as two years ago. FanGraphs still considered him that club’s #28 prospect as of July of 2023. Most of the results were poor last year but he had a ground ball rate higher than 50% at Double-A, Triple-A and the majors. For the White Sox, there’s no harm in bringing him into the organization in a non-roster capacity. Given his age and 27 days of MLB service time, there’s long-term upside if things break right, as he could theoretically be cheaply retained beyond this campaign.

The Sox’ bullpen has seen plenty of turnover in the past year, with Kendall Graveman, Reynaldo López, Aaron Bummer, Keynan Middleton and Joe Kelly all traded since last summer. Liam Hendriks had his 2024 option declined as he’s recovering from Tommy John surgery. The club is also planning to stretch out Garrett Crochet as a starter to see how that goes. The Sox have added Tim Hill and John Brebbia via free agency, while Rule 5 pick Shane Drohan is in the mix, but there could be a path for a non-roster player like Then to carve out a role. However, he is now out of options and will face a challenge in holding a roster spot even if he gets one.

Mariners Outright Juan Then

By Darragh McDonald | August 12, 2023 at 1:40pm CDT

The Mariners announced that right-hander Juan Then has cleared waivers and been outrighted to Triple-A Tacoma. It had not been previously announced that he was designated for assignment, so this move drops their 40-man roster count to 39.

Then, 23, was added to the Mariners’ roster in November of 2020 to protect him from being selected in the Rule 5 draft. A starting pitching prospect at that time, he posted a 6.46 ERA over 14 High-A starts in 2021 and then missed most of 2022 due to injury, only logging 12 innings in the minors.

This year, he’s been used primarily as a reliever. He tossed 11 innings in the majors with a 4.91 ERA, only striking out 10.4% of batters faced but keeping the ball on the ground at a 63.4% clip. But in 26 minor league frames, his ERA is an unsightly 10.04.

Since Then was added to the roster almost three years ago, he’s in his final option season and will be out of options next year. That fact, combined with his poor results of late, likely led to him passing through waivers unclaimed. This is his first outright and he has less than three years of service time, meaning he won’t have the right to reject this assignment in favor of free agency. He’ll stay in the organization without occupying a roster spot but will qualify for minor league free agency at season’s end if not added back onto the roster.

Mariners Place Penn Murfee On 15-Day Injured List

By Mark Polishuk | May 6, 2023 at 5:37pm CDT

The Mariners have placed right-hander Penn Murfee on the 15-day injured list due to right elbow inflammation, according to Ryan Divish of the Seattle Times (Twitter link).  Right-hander Juan Then is being called up from Double-A in the corresponding move, and Then’s first appearance will mark his MLB debut.

Murfee made his own Major League debut in 2022 and immediately contributed to Seattle’s bullpen, posting a 2.99 ERA over 69 1/3 innings.  Murfee’s strikeout and walk rates were well above average, and he was one of the league’s best at inducing soft contact.  The overall results have improved this season as per Murfee’s 1.38 ERA over 15 innings, except with the red flag of a drastically inflated 16.7% walk rate.  A tiny .143 BABIP has certainly helped Murfee avoid much damage, though his SIERA is 4.52.

Walks have been a problem for the Mariners’ bullpen as a whole this season, even though the relief corps has still been quite solid overall.  However, it isn’t good news that the M’s are now missing two notable relievers in Murfee and Andres Munoz, who has spent close to a month on the 15-day IL due to a right deltoid strain that seems to be a bit more troublesome than initially anticipated.  For what it’s worth, Murfee’s elbow inflammation also seems relatively minor, as Divish tweets that the Mariners were hoping he could avoid an IL trip altogether.

Then was added to Seattle’s 40-man roster back in November, protecting righty from selection in the Rule 5 Draft.  Then was an international signing for the Mariners in 2016, and after being traded to the Yankees in November 2017, was re-acquired as part of the Edwin Encarnacion trade in June 2019.  Once the 2019 season was complete, things started to go sideways for Then, who (like all minor leaguers) lost the 2020 season to the pandemic, and then struggled through two injury-shortened seasons at the high-A and Double-A levels in 2021 and 2022.

MLB Pipeline ranks Then 23rd on their list of the Mariners’ top 30 prospects, noting that his performance in the Arizona Fall League merited a return to the ranking and apparently indicated that his elbow problems were behind him.  Back at Double-A this season, Then has a 27.5% strikeout rate and 7.5% walk rate over nine innings of work, but also a 5.00 ERA.

To this end, promoting Then to the majors and skipping Triple-A entirely seems like an aggressive move for the Mariners, based both on results and the fact that Then has pitched only 30 total innings (counting AFL and Dominican Winter League work) since the start of the 2022 season.  It could be that the M’s might be viewing Then as just a short-term add before figuring out a 40-man roster opening to accommodate another pitcher.

Mariners Add 4 Players To 40-Man Roster

By Connor Byrne | November 20, 2020 at 3:22pm CDT

The Mariners announced that they have selected outfielder Taylor Trammell and three right-handers – Juan Then, Sam Delaplane and Wyatt Mills – to their 40-man roster.

Trammell, the most notable name in the bunch, is a former first-round pick (No. 35 to the Reds in 2016) and a top 100-caliber prospect who has been involved in two significant trades over the past couple years. He was first part of the mega-deal involving the Trevor Bauer, the Padres, Reds and Indians in 2019. San Diego then dealt Trammell to the Mariners in a seven-player swap before last August’s trade deadline. The 23-year-old now ranks as the Mariners’ No. 5 prospect at MLB.com.

Then, whom the Mariners acquired from the Yankees in a summer 2019 trade centering on Edwin Encarnacion, is MLB.com’s No. 14 Mariners prospect. Delaplane (No. 20) and Mills (No. 23) are also in their top 30. The Mariners added Delaplane with a 23rd-round pick in 2017 and picked up Mills, a Washington native, in Round 3 during the same year.
