• The Reds have added outfielder Boog Powell on a minor league pact, Chris Hilburn-Trenkle of Baseball America reports. Powell has bounced around several organizations since Oakland chose him in Round 20 of the 2012 draft, but he hasn’t hit poorly during his brief major league experience. The 27-year-old owns a .262/.333/.383 line in 160 career plate appearances. Most of Powell’s at-bats in recent years have come in Triple-A ball, where he has hit .279/.368/.390 in 1,356 PA.
• The Marlins have released outfielder Brayan Hernandez, per Hilburn-Trenkle. Hernandez, who joined the Miami organization in a 2017 trade with Seattle centering on David Phelps, was a touted prospect when he came out of Venezuela in 2014. The 22-year-old didn’t perform well in the minors from 2018-19, however, and managed a miserable .461 OPS in 166 trips to the plate between Single-A and low-A ball last season.
• The Mariners have signed catcher Joe Hudson to a minor league contract with an invitation to major league spring training, Ryan Divish of the Seattle Times tweets. Hudson entered the pro ranks as a sixth-round pick of Cincinnati in 2012, and he ended up appearing in the majors with the Angels in 2018 and the Cardinals last season. The 28-year-old collected just 13 plate appearances during that span, though. Hudson spent most of last year at the Triple-A level, where he hit .223/.293/.411 with 10 home runs in 222 PA.

10:40am: The Mariners and Marlins have reportedly agreed to a trade that will send right-handed setup man David Phelps from Miami to Seattle in exchange for a package of four prospects. Center field prospect Brayan Hernandez is the headliner, while the other names in the deal reportedly include right-handers Brandon Miller, Pablo Lopez and Lukas Schiraldi.

Seattle has been playing well of late, getting back to the .500 mark and drawing within 1.5 games of an American League Wild Card spot. However, the Mariners are also 15.5 games back from the Astros in the AL West, which has reportedly led them to look for assets that can be controlled beyond the current season, as their best playoff hope in 2017 is a one-game playoff.

The 30-year-old Phelps fits the bill, in that sense, as he’s controlled through the 2018 campaign via arbitration. He’s earning $4.6MM in 2017, with about $1.86MM of that sum yet owed to him through season’s end.

The former Yankee initially went to Miami alongside Martin Prado as part of the trade that sent Nathan Eovaldi to New York. After spending much of his career as a starter and long reliever, Phelps’ career took off with a 2016 move to a late-inning role. The righty’s velocity ticked from the low 90s to an average in the 93-94 mph range, and he’s dramatically upped his strikeout rate while pitching in a setup capacity.

Dating back to Opening Day 2016, Phelps has worked to a 2.69 ERA with 11.1 K/9, 4.0 BB/9 and a 46.4 percent ground-ball rate through 133 2/3 innings. His strikeout rate is “down” in 2017, but he’s still averaging 9.8 punchouts per nine innings pitched. His arm will be a boost to a Mariners relief corps that currently ranks 13th in baseball with a 4.05 ERA but carries more troubling marks in both FIP (4.44) and xFIP (4.45). Those ERA alternatives come in at 25th and 21st in baseball, respectively, indicating that the Mariners are perhaps fortunate to have gotten the results they have out of their bullpen to date. (Then again, Seattle boasts a superlative defense, particularly in the outfield, so perhaps it should be expected that their pitchers would outperform fielding-independent metrics.)

The Seattle ’pen is currently anchored by sophomore closer Edwin Diaz, who has been inconsistent in 2017 but can overpower opposing lineups with a triple-digit fastball and one of baseball’s best strikeout rates. Nick Vincent has also been brilliant in Seattle, working to a 2.04 ERA in 39 2/3 innings, while southpaw James Pazos has averaged nearly 11 strikeouts per nine innings en route to a 3.68 ERA. Former Mariners closer Steve Cishek represents another right-handed option, but health has been an issue for him in recent years as his numbers have declined.

Beyond that, Seattle has seen some of its anticipated setup men, particularly right-hander Dan Altavilla, take a step back in 2017. Phelps figures to pick up some of that slack and will join Diaz, Vincent, Pazos, Cishek, Tony Zych and Marc Rzepczynski in the Mariner bullpen.

Hernandez is the big get for the Marlins in the deal. The 19-year-old ranked as one of the 10 best international free agents in the 2014-15 crop and inked a $1.85MM bonus with Seattle at the time. Hernandez split the 2016 season between the Dominican Summer League and the Rookie-level Arizona League, hitting a combined .278/.325/.425, and he’s off to a .252/.306/.408 start with the Mariners’ short-season Class-A affiliate.

Jim Callis and Jonathan Mayo of MLB.com rank Hernandez as Seattle’ No. 6 prospect, noting that he flashes all five tools but is still projection over performance at the moment. He received 60 grades on his speed and arm from Callis and Mayo with a 55 on his glove, and their report notes that his overall offensive development will determine if he can reach his ceiling as an everyday center fielder. Baseball America rated him 16th among Seattle farmhands this past winter, agreeing that the defensive tools are impressive and praising his “solid, consistent contact” but also questioning his ability to generate power now or in the future.

The 22-year-old Miller has spent the season with the Mariners’ Class-A affiliate in the Midwest League, working to a 3.65 ERA with 8.4 K/9, 2.0 BB/9 and a 46.8 percent ground-ball rat in 101 innings/18 starts at that level. Callis and Mayo list his heater at 90-93 mph with good command of the pitch and give him credit for a plus slider, though reports indicate that he lacks an average third offering and could be destined for a bullpen role. He ranked 16th among Mariners prospects, per MLB.com, while BA pegged him 25th among Seattle prospects this offseason. Both reports tout his fastball’s exceptional spin rate. If all breaks right, Miller could pan out as a back-of-the-rotation starter.

Lopez is a 21-year-old starter that has spent the year in Class-A Advanced. While his 5.02 ERA through 100 innings doesn’t look appealing, he’s posted an excellent 89-to-13 K/BB ratio with a 49 percent ground-ball rate, creating some optimism that he’s been hit with some poor luck. (A .341 BABIP lends further credence to that notion.) MLB.com placed him 22nd in Seattle’s system and gave him three average offerings (fastball, curveball, changeup) but no plus pitch. He was 31st on BA’s offseason rankings, and their report notes that he has a 2014 Tommy John surgery in his history but is a “supreme strike-thrower” with impressive ground-ball tendencies.

Schiraldi comes from good baseball genes, as his father, Calvin, played in the Majors for parts of eight seasons with the Mets, Red Sox, Padres, Cubs and Rangers. The younger Schiraldi didn’t crack any Mariners top prospect rankings but has a gaudy 15.2 K/9 rate in 37 1/3 innings of work at Class-A Advanced. However, he’s also not particularly young for the level at 23 years of age, and he’s worked to a 4.58 ERA with a 6.5 BB/9 rate.

Ultimately, the Marlins will secure four players in exchange for a year and a half of a quality setup man while also saving a bit of cash for the remainder of the 2017 season. While it’s tempting to look at the sheer volume of players and wonder how this will impact the market for other relievers — especially those that are controlled beyond the 2017 season, such as Brad Hand and Zach Britton — it’s also worth emphasizing that Seattle’s farm system is generally regarded as weak. That bit of context should absolutely be considered when debating the value of other relief arms, and it seems unlikely that the volume of the Phelps deal “raises the bar” for other relievers throughout the league.

MLB.com’s Mark Feinsand first reported that the Mariners were in talks to acquire a reliever and that Phelps was the target. MLB.com’s Jon Morosi termed the deal “fairly close,” and Yahoo’s Jeff Passan pushed it further to “imminent.” FanRag’s Jon Heyman tweeted that the trade was indeed finalized, while Joel Sherman of the New York Post tweeted that Seattle was sending multiple minor leaguers to Miami. Passan and Heyman added a bit more detail on the return (Twitter links), with Passan ultimately reporting Hernandez as the headliner. Sherman broke news of the other three players in the deal.

JULY 2nd: The Mariners have agreed to terms with top international prospect Brayan Hernandez, tweets Jesse Sanchez of MLB.com. Hernandez, a 16-year-old outfielder from Venezuela, will receive a $1.85MM bonus, per Sanchez.

A switch-hitter, Hernandez ranked No. 8 on MLB.com’s list of top international amateurs and third on Baseball America’s version of the same list. Sanchez, BA’s Ben Badler and Scout.com’s Kiley McDaniel have all connected the Mariners to Hernandez in the past, with McDaniel making the link all the way back in February.

Badler called Hernandez one of the most well-rounded players and best athletes in this year’s class. He has the potential to hit 15 to 20 homers with slightly above-average speed but a below-average throwing arm, per Badler. Sanchez calls him a contact hitter with a balanced setup that could improve quickly upon getting into regular games, due to a natural swing and strong hand-eye coordination.

• The Brewers will call up top pitching prospect Jimmy Nelson to start Sunday to take the rotation turn of Yovani Gallardo, tweets Tom Haudricourt of the Milwaukee Journal Sentinel. At this point, at least, it seems that Nelson may only get one start, as Gallardo is not expected to miss significant time. As I explained back in April, Nelson already has 27 days of service to his credit. Accordingly, if he did stay in the bigs from this point forward, he would accrue enough service time to set himself up to become eligible for an additional year of arbitration as a Super Two player, though he will not be able to pass the one-year service mark by the end of the year.
• Milwaukee’s decision to deal for reliever Will Smith (in exchange for outfielder Norichika Aoki) has been a key element in the team’s success this year, writes Ken Rosenthal of FOX Sports. The team’s pro scouting staff gave Smith high marks, leading GM Doug Melvin to pull the trigger on the trade. He has allowed just one earned run in 21 2/3 innings of work, posting 12.9 K/9 against 4.2 BB/9.
• Pitcher Jason Marquis was scheduled to throw for scouts today, Rosenthal reports in the same piece. The 35-year-old had Tommy John surgery last summer after tossing 117 2/3 innings of 4.05 ball for the Padres.
• Another former big leaguer looking to make a return is infielder Bill Hall, who tweets that he is on the comeback trail. The 34-year-old has spent time at third, short, second, and all over the outfield in his 11 seasons of MLB action, and owns a career .248/.308/.436 line. He spent last year with the Angels’ Triple-A affiliate, putting up a .225/.321/.407 mark with 17 home runs in 452 plate appearances.
• Ben Badler of Baseball America has the latest updates on the July 2 market. Yesterday, Badler ticked through the top ten expected bonuses among players eligible to sign for the 2014-15 period, along with the clubs expected to land them. Leading the way is infielder Gilbert Lara, who has been linked to the Brewers and could earn $3MM. Four of the players are expected to go to the Yankees, with the Rays, Red Sox, and Blue Jays also said to be set up for some large outlays among AL East clubs. (The American League could also be in line to pick up the other two players on that list, with the Mariners potentially in position to sign outfielder Brayan Hernandez and the White Sox predicted to land righty Huascar Ynoa.) And today, he profiles a set of field position prospects who figure to be among the best available players, headlined by Venezuelan shortstop Kenny Hernandez, who Badler says could get a nine-figure bonus.
• Meanwhile, the Yankees are reportedly prepared to ink Korean shortstop Hyo-Jun Park for a $1.1MM bonus, according to a report from Korean outlet Naver (Korean language link; translated article; hat tip to River Ave. Blues ). Jason Cohen of Pinstripe Alley recently compiled the available information on Park, who is said to be a solid all-around player.
