Jesse Hahn Undergoes UCL Surgery

Royals righty Jesse Hahn underwent surgery on the ulnar collateral ligament in his pitching elbow, as Rustin Dodd of The Athletic was among those to report on Twitter. Hahn is expected to require approximately six months of rehabilitation, indicating that he may or may not be ready to return for the start of camp next spring.

Fortunately, Hahn did not require the famed Tommy John surgery that is often necessary to fix UCL damage. Instead, he will become the latest pitcher to undergo a “primary repair” procedure. The alternative approach comes with the promise of a much shorter rehab timeline, though it is also not nearly as established as the standby TJS.

About a year and a half ago, Seth Maness became the first known MLB hurler to be treated with the primary repair approach. He ended up signing with the Royals for his comeback attempt, so the team has some direct experience in this area. Unfortunately, Maness has not been able to regain his prior form to this point, though he did make it back to the majors briefly in 2017.

Hahn, 29, landed with the K.C. organization in an early-2018 swap in which the Athletics acquired lefty Ryan Buchter and took on more than half of Brandon Moss‘s $7.25MM salary. While Hahn opened his MLB career with 170 innings of 3.23 ERA pitching, he was coming off of consecutive rough seasons at the time of the move.

Though the hope surely was that he would contribute to the MLB staff this year, and perhaps even regain some of his prior form, Hahn has only thrown six minor-league innings this season. That’s particularly disappointing given that he entered camp feeling healthy. Hahn was knocked around in two Cactus League innings before experiencing elbow issues and going on the 60-day disabled list in early March.

Rays Pulled Sergio Romo Off Revocable Waivers

Aug. 24: Heyman tweets that the Rays did indeed pull Romo off waivers after “multiple” American League clubs placed a claim on the right-hander.

Aug. 23: Veteran reliever Sergio Romo is “not going anywhere,” a source tells Jon Heyman of Fancred (via Twitter). It seems “likely,” Heyman adds, that Romo was pulled back from revocable waivers after being claimed.

Romo, 35, featured prominently on MLBTR’s latest ranking of the top August trade candidates. He’ll be a free agent again at season’s end, so there isn’t much reason for the out-of-contention Rays to hang onto him.

On the other hand, Romo is only owed about half a million dollars for the rest of the season. And he has played a notable role for an organization that has built some momentum with its unusual approach to building out a pitching staff. It certainly seems possible the Rays will seek to bring him back over the offseason to come; perhaps that consideration also weighed in the decision.

In 56 1/3 innings this year, Romo carries a strong 3.36 ERA with peripherals to match. He has generated 10.1 K/9 against 2.9 BB/9 and still draws swings and misses on over 13% of his pitches. Romo has held opposing hitters to a .294 wOBA, with Statcast suggesting he has been even a bit better than that (.286 xwOBA).

While it seems he’ll remain in Tampa Bay to finish out the year, Romo ought to be a fairly popular target in free agency over the winter to come. The veteran is on pace to finish out his 11th-straight MLB campaign with a sub-4.00 ERA and recorded 18 saves this year, which may still hold some sway for certain teams. Whether he can secure a multi-year commitment remains to be seen, but he ought at least to have a strong possibility of beating the salaries he has settled for in each of the past two years ($3MM and $2.5MM, respectively).

Cubs Health Updates: Darvish, Chatwood, Morrow, Duensing

The Cubs remain in good position in the NL Central, in no small part due to the recent heroics of recently acquired pitcher Cole Hamels. The veteran just wrapped up a complete-game performance tonight and has allowed less than one earned run per nine innings in his first five starts in a Cubs uniform. Of course, he would likely not have ended up in Chicago were it not for the difficulties experienced by a few of the team’s recently signed, high-priced starters.

  • Yu Darvish, Hamels’s former rotation mate in Texas, has already been declared out for the rest of the 2018 season. He addressed that fact with reporters today, with MLB.com’s Carrie Muskat among those on hand. The veteran righty says he felt all along “there was something else other than the tightness” he was experiencing in his pitching arm, so much so that the diagnosis of a stress reaction came as something of a relief. Darvish indicated that he’s not even thinking about the season to come so much as he is trying to care for his ailing arm. Still, he expressed confidence that he’ll bounce back and be “stronger going forward.” That’ll obviously be the hope of the Cubs organization, which still has $101MM invested in Darvish after the present season.
  • The club also announced today that righty Tyler Chatwood is headed to the DL with hip soreness, as Mark Gonzales of the Chicago Tribune covers. He’ll be replaced on the roster by Dillon Maples, for the time being, with Alec Mills set to come up to start tomorrow. Chatwood has been plagued by walks all year long, racking up 93 to go with his 85 strikeouts over 101 2/3 innings. That’s simply not a manageable rate of free passes, as his 5.22 ERA reflects. Details of the new malady remain scant, but it certainly seems there are good reasons for the club to find cause to give Chatwood a breather regardless.
  • Another major recent open-market signee, Brandon Morrow, has performed as hoped when he has been available. But the closer has been sidelined for over a month with a balky elbow and still lacks a clear timeline. He went in for a checkup today, says Muskat. That examination evidently did not reveal anything of particular note, though it was not arranged due to any fear of a setback. It seems the hope remains that Morrow will return at some point in the final month of the regular season.
  • In other Chicago reliever news, Brian Duensing — yet another hurler who signed with the Cubs in free agency last winter — is headed for a rehab assignment. The 35-year-old southpaw, who carries an ugly 7.34 ERA on the year, has been on the shelf for the past several weeks with a shoulder ailment.

White Sox Reinstate Welington Castillo From Restricted List, Place Him On 10-Day DL

White Sox catcher Welington Castillo has formally concluded his 80-game PED suspension, but he won’t be going straight from the restricted list onto the active roster. The Chicago organization announced today that the veteran will instead move onto the 10-day disabled list with shoulder inflammation.

Castillo, 31, got off to a strong start at the plate this year after inking a two-year, $15MM contract early last winter. He was producing at a .267/.309/.466 clip with six home runs in 123 plate appearances when news broke of his positive test for erythopoieton, a substance prohibited under the MLB-MLBPA Joint Drug Agreement.

Though he had played in five rehab games prior to the conclusion of his suspension, Castillo is evidently not ready to return to the majors. It’s not clear at this point how long he’ll be down, but any minute chance of a late-August trade can assuredly be ruled out.

In his absence, the White Sox have relied upon Omar Narvaez and Kevan Smith behind the plate. The former has been quite impressive with the bat, improving upon his solid numbers entering the year with an under-the-radar breakout season. He’s hitting at a .280/.374/.435 clip with an impressive 41:30 K/BB ratio in 240 plate appearances.

Presumably, Castillo will share time with Narvaez when this DL stint is over. But it stands to reason that the organization will want to get a long look at the younger, more controllable player. It’s certainly possible that Castillo will end up as trade fodder at some point, but it’s also worth bearing in mind that the South Siders could see the ensuing offseason as an opportune time to make some roster improvements in hopes of challenging in a division that has easily been the worst in baseball in 2018. Hanging onto Castillo, rather than trying to move him after a messy campaign, may well be the most sensible approach.

Brewers Option Corey Knebel, Zach Davies

The Brewers have optioned righties Corey Knebel and Zach Davies, per the MLB.com transactions page. (H/t MLB.com’s Adam McCalvy & Todd Rosiak of the Milwaukee Journal-Sentinel; Twitter links.) Davies had been on a rehab assignment following an extended absence.

This move is notable enough for what it says about two of the team’s most important pitchers heading into the season. But it’s also an intriguing development with the revocable waiver trade deadline drawing near.

[RELATED: Brewers Depth Chart]

Knebel was expected to anchor the Milwaukee pen, but carries a 5.08 ERA through 39 innings on the season. He has generated 12.7 K/9 against 4.4 BB/9 along with a 50.0% groundball rate, but has also been touched for home runs on 28.0% of the flyballs put in play against him. Knebel is sitting just under 97 mph with his average fastball, but has lost some of swinging-strike gains from 2017, with his 13.9% rate falling to 11.6% this year. His struggles have deepened of late, as he has coughed up eight earned runs in his past 6 1/3 innings.

As for Davies, who turned in solid campaigns from the rotation in each of the past two years, the 2018 season has been a rough one thus far. He only managed a 5.23 ERA through eight starts before hitting the shelf with shoulder troubles. Davies has actually taken more starts in the minors this year than in the majors, owing to a halting rehab course.

While Knebel will head to Triple-A to work out the kinks, Davies was formally assigned to the organization’s nearby Class A affiliate. The reason for the latter’s placement isn’t entirely clear, but it could be that the club thinks it may need to bring him back onto the MLB roster on short notice or that he’ll be getting some added rest time without re-starting another rehab stint. Or, perhaps this is just a holding spot for the time being while the next steps are hammered out.

Both pitchers will need to remain on optional assignment for at least ten days unless an active roster spot opens due to a DL placement. It’s at least worth noting that, to this point of the season, MLB players have only accrued 147 days of service. Knebel, a Super Two this year, will cross into the 3+ service class regardless of whether he returns to the MLB roster. Davies, though, entered the campaign with 2.020 service years on his ticker and is therefore still a few days shy of reaching arbitration eligibility in the coming offseason. He would still likely qualify as a Super Two, but that’d mean pushing back his eventual free agency by one season. Whether or not that’s a factor isn’t at all clear; it certainly could be that the organization plans to bring Davies back when rosters expand, if not sooner.

For the time being, there’s no known replacement for Knebel on the active roster. Milwaukee is off today. As Rosiak notes, he could be replaced by Joakim Soria, if he’s activated from the DL tomorrow. But the open roster spot could also be filled from the outside. Several starting pitchers are rumored to be on waivers or to have cleared waivers. It’s certainly possible — but by no means certain — that the Brewers are contemplating the acquisition of an outside arm.

Braves Outright Ryan Flaherty

The Braves outrighted Ryan Flaherty after he cleared waivers, as Gabe Burns of the Atlanta Journal-Constitution was among those to tweet. The veteran infielder has accepted the assignment, but can still choose to elect free agency at season’s end.

Flaherty, 32, rushed out to a hot start at the plate but steadily trailed off over the course of the season. Through 172 total plate appearances in 2018, he’s slashing just .222/.298/.301 — good for a meager 59 wRC+ that falls in line with his numbers in recent seasons.

Flaherty’s role diminished as well with Johan Camargo returning to action and Charlie Culberson engaged in his own surprising run of success. (Interestingly, Statcast actually gives Flaherty the slight edge in xwOBA for the year over Culberson, taking a rather dim view of both players’ batted-ball output.) When a roster spot was needed recently, Flaherty was designated for assignment. He had taken only 32 plate appearances over the preceding two months.

Despite his offensive struggles, Flaherty will “likely” be added back to the MLB roster at some point in September, Burns tweets. Of course, that would still require the Atlanta organization to open a 40-man spot, so other considerations could still intervene. Presumably, if he does make it back to the majors this season, Flaherty will see occasional time as a defensive and baserunning replacement.

Braves Select Chris Stewart

The Braves announced today that they’ve selected the contract of veteran backstop Chris Stewart. Gabe Burns of the Atlanta Journal-Constitution first indicated that the veteran backstop was returning to the Majors (via Twitter). Stewart has been playing at Triple-A since being outrighted earlier this season.

The reason for the promotion seems to be an injury to catcher Kurt Suzuki, which he sustained last night upon being hit on the elbow/triceps area by a fastball from Pirates righty Clay Holmes. Fortunately, the Atlanta organization announced earlier today that Suzuki was cleared of a fracture and has been diagnosed only with a left triceps contusion. Whether a stint on the DL will be required is not yet known, but if one is deemed necessary, it doesn’t seem that it’ll come today. Outfielder Michael Reed was optioned to Triple-A Gwinnett to open roster space for Stewart’s return.

Stewart, 36, rarely strikes out but has never hit much in the majors and has struggled in particular since the start of the 2016 season. He’s slashing only .209/.287/.269 this year in 152 Triple-A plate appearances with Gwinnett. Still, Stewart is regarded as a sturdy, defensive-minded reserve option to have on hand and will be trusted to support Tyler Flowers as needed while Suzuki is unavailable. He’s gone 10-for-27 (37 percent) in halting stolen bases at the Triple-A level this season and has a solid track record in terms of pitch framing.

Nationals Activate Stephen Strasburg

The Nationals have activated righty Stephen Strasburg from the 10-day disabled list, per a club announcement. He’ll start for the organization tonight.

Strasburg had been sidelined with a cervical nerve impingement. This’ll be the second time that he has attempted to return; previously, he made it back only for one outing. He last pitched in the majors one month ago.

The hope had long been that Strasburg would provide a jolt as the Nats continued to chase down the division-leading Braves and Phillies. But the club has failed to gain ground as it expected, leading to the decision yesterday to trade away quality left-handed hitters Daniel Murphy and Matt Adams.

Of course, the returns of Strasburg and reliever Kelvin Herrera (activated yesterday) will still improve the D.C. roster. But the 7.5-game advantage held by Atlanta represents quite an obstacle, particularly with Murphy and Adams now suiting up for rival National League ballclubs.

Whatever happens in the standings, these next five weeks will afford Strasburg a chance to finish another injury-limited season on a high note. The 30-year-old has thrown 85 1/3 innings of 3.90 ERA ball this year, though he does carry typically strong K/BB numbers (101:21). Strasburg is under contract through 2023, at a total cost of $135MM over the next five seasons, but may elect to opt out after 2019 or 2020.

Twins Release Taylor Motter

The Twins organization announced today that it has released utilityman Taylor Motter. He had been playing at Triple-A Rochester.

Motter, 28, has only seen 16 games of major-league action this year but has taken 411 MLB plate appearances since the start of 2016. He’s capable of playing all over the field, but hasn’t distinguished himself at the plate. Motter is a .191/.263/.312 hitter in that span, with ten home runs and 13 steals.

Since he was claimed off waivers from the Mariners in late May, Motter has spent most of his time in the upper minors. On the year, he carries a meager .187/.277/.352 batting line in 364 plate appearances in the Seattle and Minnesota systems.
