• The Mariners have outrighted utilityman Shawn O’Malley to Triple-A, per a club announcement. He had previously been designated for assignment. As Bob Dutton of the Tacoma News Tribune notes on Twitter, that’s more or less a formality at this stage of the year, as O’Malley will be able to enter the open market at year’s end as a minor-league free agent. Of course, he’ll still be on hand if a need arises over the next three weeks. O’Malley, 29, has not appeared in the majors this year but did see 89 games of action for Seattle in 2016. The former fifth-round draft pick hit just .229/.299/.319 in his 232 plate appearances last year, though, and then missed a big chunk of time earlier this season owing to an appendectomy and shoulder problems. O’Malley has hit just .205/.250/282 in twenty games of action at Triple-A in the current campaign.
• Also outrighted, per the Padres, was righty Kevin Quackenbush. He had entered the season on track to qualify for arbitration at season’s end, but only appeared in twenty contests while struggling to a 7.86 ERA with 7.9 K/9 and 5.5 BB/9. Quackenbush is still just 28 and has had far more productive stints in the majors in the recent past. He also managed a 3.90 ERA in his 27 2/3 Triple-A frames. While his outlook with the Pads remains cloudy, then, he could receive a shot at earning a bullpen spot — in San Diego or elsewhere — in Spring Training next year.

10:12am: In a surprising development, the Cardinals have dealt righty Mike Leake to the Mariners. Young infielder Rayder Ascanio will go to St. Louis in the swap, with $750K of international bonus pool spending capacity and unannounced cash considerations also heading to Seattle.

It’s not yet known how much cash the M’s will take on in the deal or what players may be headed in return. Leake had already cleared revocable waivers, per Derrick Goold of the St. Louis Post-Dispatch (via Twitter). That was to be expected. Leake is earning $15MM this year, with about $2.5MM left to go. He remains under contract through 2020, with a $53MM total guarantee — including a $5MM buyout of a 2021 mutual option.

Leake’s contract includes full no-trade protection, so his approval was required for the deal to go through. He has indeed waived the clause, per Nightengale (Twitter link). Notably, Leake has spoken of his desire to be closer to family in Arizona and will now at least get to spend Spring Training there; that motivation and others may have aided his decision.

Since signing on with the Cards before the 2016 season, Leake has shown the durability that earned him the contract, throwing 330 2/3 innings over 56 starts. But he has also managed only a 4.46 cumulative ERA while compiling 6.2 K/9 against 1.8 BB/9. Leake has struggled especially of late, working to an 8.88 ERA in his five starts in August.

Assuming he can get back on track, Leake will help steady a Seattle rotation that has faced a steady barrage of injuries. Felix Hernandez, James Paxton, Hisashi Iwakuma, and Drew Smyly are all on the DL, with only the first two expected to return this season. The club has fallen three games off of the AL Wild Card pace, but evidently still feels compelled to push for the postseason this year.

Of course, Leake will also represent a piece of the future picture. The Mariners will almost certainly bid adieu to Iwakuma, Smyly, and Yovani Gallardo over the winter. Erasmo Ramirez and even David Phelps — both acquired earlier this summer — could be rotation options (though the latter has worked from the pen), as could Gonzales. Still the team was clearly in need of at least one more arm to go along with King Felix and the Big Maple.

This is the second notable recent swap between these organizations, who had previously struck a deal that sent young lefty Marco Gonzales to Seattle for outfielder Tyler O’Neill. Leake may well end up bumping Gonzales out of the Mariners rotation for the time being.

Seattle will also pick up some bonus pool money, which St. Louis wasn’t able to utilize anyway following penalties for prior spending. The Cards will also add the 21-year-old Ascanio, a middle infielder out of Venezuela. Ascanio has played at the Class A and High-A levels this year, posting a .217/.295/.355 slash over 450 total plate appearances. That’s not a lot of offense, though he has knocked nine balls over the fence — more than he had over his four prior professional seasons combined.

St. Louis remains in the hunt for both the NL Central crown and a Wild Card spot, though the team enters play today five games out of the postseason picture. While the rotation has had its issues, Luke Weaver has emerged as a quality option since returning to the majors recently, perhaps freeing the club to deal Leake. Another young righty, Jack Flaherty, likely isn’t far behind.

Ultimately, dealing Leake may have more to do with future considerations than the club’s immediate postseason hopes. Moving some of the contract will open some payroll space for 2018 and beyond, though it also takes away one rotation option with Lance Lynn slated to hit the open market and Adam Wainwright entering the final year of his contract. The club does still control Carlos Martinez and Michael Wacha, in addition to the two talented but less-experienced arms noted above, and will hopefully welcome Alex Reyes back into the fold next year. Parting with Leake, though, could conceivably keep the door open for the return of Lynn or lead the team to acquire another rotation piece over the offseason.

Bob Nightengale of USA Today (via Twitter) first said a deal involving Leake was close, per Ken Rosenthal of The Athletic (via Twitter). MLB.com’s Jen Langosch tweeted the detail on the international money.

Aug. 23: The Mariners have designated outfielder Leonys Martin for assignment, per Ryan Divish of the Seattle Times (via Twitter). Martin’s active roster spot will go to David Phelps, who was activated from the 10-day DL.

This represents the second trip through DFA limbo on the year for Martin, who was outrighted and later re-selected to the roster. The 29-year-old was much better in his second stint this season, but still managed only a .230/.266/.426 batting line in the 64 plate appearances since he returned to the majors in late July.

Martin is likely to clear waivers, given that he is earning $4.85MM for the season, and can elect free agency if he is outrighted. Doing so, however, would mean forfeiting the remainder of that $4.85MM payday — a sum of roughly $1.03MM. (Players do not earn the right to reject an outright and retain their salary until clearing five years of MLB service.) Martin is eligible for arbitration again this fall, but it seems all but certain he’ll be non-tendered even if he stays in the Seattle organization through the end of the year.

The 29-year-old Gomez signed with the Brewers less than a month ago, on July 15, and performed well with their Colorado Springs-based Triple-A affiliate. Gomez totaled 8 1/3 innings with the club and allowed two earned runs on seven hits and a walk, with seven strikeouts. He wasn’t nearly as effective at the major league level this year with the Phillies, who released him June 24. Philadelphia parted with Gomez after he turned in a 7.25 ERA across 22 1/3 innings and experienced a dip in his already low velocity, though he did post career-best strikeout and walk numbers (8.46 K/9 and 2.82 BB/9) and a 50.7 percent ground-ball rate.

If Gomez ultimately gets to Seattle, it’ll be his fourth major league club since he debuted with the Indians in 2010. Gomez was at his best with the Pirates from 2013-15, when he combined for 3.28 ERA and a 51.5 percent grounder rate in 142 2/3 innings. Last season, Gomez’s first in Philadelphia, he served as the team’s closer and continued to eat innings (68 2/3) and induce grounders (52 percent). Gomez fell out of favor, though, with an 8.33 ERA during the season’s second half. Overall, he registered a 4.85 ERA and 37 saves, earning him $4.2MM in his final year of arbitration eligibility.

Albers had been working at Triple-A Gwinnett; now, he’ll help bolster the depth for the Mariners, who have suffered a variety of pitching injuries of late. The 31-year-old has limited experience in the majors, with just 17 total appearances  over parts of three seasons, but he has shown rather well this year at the highest level of the minors.

Through his 120 2/3 innings to date for Gwinnett — covering 17 starts as well as nine relief appearances — Albers carries a 2.61 ERA. He’s also carrying 8.6 K/9 against just 1.4 BB/9 as well as a solid 46.1% groundball rate.

Whether Seattle intends to bring Albers up in the near-term isn’t clear. At a minimum, he’ll provide the organization with a new depth piece as it filters arms up to account for the recent DL placements of David Phelps, Felix Hernandez, and James Paxton.

• The White Sox have added righty Steve Johnson from the Orioles, per an announcement from the latter organization. Cash considerations are heading back in return. Johnson, 29, becomes the latest pitcher added to the Triple-A roster by the South Siders, who are lining up options for the MLB roster down the stretch. He has 76 major league frames of 4.26 ERA pitching on his ledger, with 10.2 K/9 but also 5.6 BB/9 in that stretch. The free passes have never been quite as much of an issue for Johnson in the minors, though, where he has been excellent at times. Things haven’t gone quite as well this year, though, as Johnson owns a 5.30 ERA in his 37 1/3 frames — though he has still managed more than a strikeout per inning.

Frieri, 32, returned to the Majors in 2017 after sitting out the 2016 campaign entirely (outside of a stint in the Dominican Winter League). The former Angels closer drummed up some interest by pitching for his native Colombia in the 2017 World Baseball Classic. That showing helped Frieri to latch on with the Yankees on a minors pact, and he later signed with the Rangers after opting out of that pact with New York. He pitched seven innings out of the Texas ’pen, allowing four runs on six hits and six walks with five strikeouts.

While those numbers aren’t pretty, Frieri has a strong 2.63 ERA with 11.2 K/9 against 4.0 BB/9 in 27 1/3 Triple-A frames this year — including 5 1/3 innings of one-run ball with an 8-to-3 K/BB ratio since last being sent to Triple-A by Texas. He’s mostly a depth option for now, it seems, but Frieri does have a solid overall track record in the Majors, even in spite of his lack of recent results.

In 303 1/3 big league innings, he owns a 3.59 ERA with 11.5 K/9 and 4.2 BB/9. Frieri is an extreme fly-ball pitcher (career 26.4 percent ground-ball rate), though if he reaches the Majors, concerns surrounding that trait could be somewhat mitigated by the spacious dimensions of Seattle’s Safeco Field and an excellent Mariners outfield defense.

With the DL placement of Phelps, Seattle has cleared way for the activation of just-acquired first baseman Yonder Alonso. He’ll suit up against his former team, the Athletics, in tonight’s action.

Of course, the M’s had only just acquired Phelps, too. It certainly hurts to see the organization’s top deadline acquisition head out of action so soon after he had joined the team. That said, it seems promising that he was not deemed to have a more serious elbow issue. Since coming to Seattle, Phelps has made seven appearances, allowing two earned runs over six innings while racking up 11 strikeouts and just one walk.

Hernandez had already gone on the DL a few days ago, with the team stating at the time that he was dealing with biceps tendinitis. With the new diagnosis — a repeat of an injury that drove King Felix to the DL for about two months earlier this year — it seems a lengthier absence is to be expected. That comes at an inopportune moment, as Hernandez had picked up his output over July, working to a 3.86 ERA with 36 strikeouts and 14 walks in 35 innings.

As Seattle welcomes Alonso to the fold, it sits just one game out of Wild Card position. But the club’s pitching health and depth have continued to be a problem. Hernandez returns to a disabled list that already includes Hisashi Iwakuma and Drew Smyly. Just-added southpaw Marco Gonzales took a spot start for Hernandez, but he was knocked around. Other 40-man members who have taken starts in the majors this yearinclude Andrew Moore, Sam Gaviglio, and Chase De Jong.

The 25-year-old Peterson had been with the Mariners since they used the 12th overall pick on him in the 2013 draft. Peterson was a fixture on top 100 prospects lists in the early going, but since holding his own at the Single-A and Double-A levels from 2013-14, his bat has cooled. Peterson hasn’t been able to conquer Triple-A pitching, as he batted .260/.316/.418 in 627 plate appearances with the Mariners’ affiliate in Tacoma. He hit just .264/.323/.414 there this year, good for 12 percent worse than the Pacific Coast League average, according to wRC+.

Peterson has three options remaining, per Roster Resource, and could get a shot in the majors at some point with the rebuilding White Sox. For now, he’ll head to Triple-A Charlotte.
