Mariners GM Jerry Dipoto said the team could use David Phelps in the starting rotation in the future, but not this season.
The Mariners acquired Phelps Thursday in a deal that sent four prospects to Miami. Phelps has made 64 big league starts and could return to that role at some point but for now, the Mariners are content using him out of the pen. The 30-year-old right-hander has contributed a 3.45 ERA with 18 holds this season. Jul 20 - 7:54 PM

Mariners acquired RHP David Phelps from the Marlins for OF Brayan Hernandez, RHP Brandon Miller, RHP Pablo Lopez, and RHP Lukas Schiraldi.

Word of the deal was first reported late Wednesday night by's Mark Feinsand. It just took a little while longer for the Marlins to pick through the Mariners' minor league system. Phelps will work as a setup man in Seattle for young closer Edwin Diaz, and it should be a good fit. The 30-year-old right-hander boasts a 2.69 ERA and 11.1 K/9 in 133 2/3 innings since the beginning of the 2016 season and he's averaging a career-best 94.4 mph on his fastball this summer. Phelps will be arbitration-eligible in 2018 with free agency coming in 2019.

Jon Heyman of FanRag Sports confirms that David Phelps has been traded to the Mariners.

Jeff Passan of Yahoo Sports says the Marlins will receive four minor leaguers in return, and one of them is 19-year-old outfielder Brayan Hernandez. Phelps figures to slide into a setup role with Seattle, giving the Mariners an improved bridge to young closer Edwin Diaz. The 30-year-old right-hander has a 3.45 ERA and 51 strikeouts in 47 innings this season, and a 2.69 ERA and 11.1 K/9 in 133 2/3 innings since the beginning of 2016.

David Phelps to the Mariners is "at the finish line," according to Jeff Passan of Yahoo Sports.

Joel Sherman of the New York Post adds that the trade is expected to be completed sometime on Thursday. FOX Sports' Ken Rosenthal reported early this morning that the Marlins were not enamored with the available options in the Mariners' minor league system, but it seems the two clubs have found a match. Or are very close to finding one. Phelps, 30, boasts a 2.69 ERA and 11.1 K/9 over his last 133 2/3 innings dating back to the beginning of the 2016 season and he is under contractual control through 2018.

According to Jon Morosi of MLB Network, the Mariners are "fairly close" on a trade for Marlins right-hander David Phelps.'s Mark Feinsand was first to report word of the Mariners' growing interest in Phelps late Wednesday night. The 30-year-old reliever hasn't been as effective this season as he was in 2016, but he would still fit nicely into a setup role in Seattle and he is controllable through 2018. It sounds like there could be something official soon, though FOX Sports' Ken Rosenthal tweeted early Thursday morning that the Marlins are "not in love" with the offerings in the Mariners' farm system.

FOX Sports' Ken Rosenthal confirms that the Mariners are talking to the Marlins about right-hander David Phelps.

Rosenthal adds, however, that there is "no match" at this point and might never be one because the Marlins are "not in love" with the players in the Mariners' minor league system. Phelps, 30, has posted a sharp 2.69 ERA and 11.1 K/9 over his last 133 2/3 innings dating back to the beginning of the 2016 season -- some of that as a starter. He also carries one more year of contractual control in 2018. Miami should be able to get a decent prospect or two in return for him.
Jul 20 - 10:02 AM

Craig Mish of Fantasy Sports Radio on SiriusXM reports that the Diamondbacks are showing "significant interest" in David Phelps.

Mish adds that it's possible the D'Backs could be interested in a trade that involves both Phelps and A.J. Ramos, although the Marlins would figure to net more in a trade if they dealt the relievers separately. Phelps and Ramos both have one year of arbitration eligibility remaining and it's clear that the out-of-contention Marlins aren't interested in paying them raises this winter. Adding Phelps would help Arizona fortify a bullpen that includes the shaky Fernando Rodney in the ninth inning.
Jul 14 - 11:11 AM

According to Bob Nightengale of USA Today, more than 10 teams have inquired with the Marlins regarding the availability of David Phelps.

The 30-year-old hurler will be entering his final year of arbitration over the winter and looks to be one of the top trade chips that the Marlins will have at the deadline. Phelps has the ability to both start and pitch out of the bullpen and owns a 48/16 K/BB ratio across 44 innings on the season.

Marlins activated RHP David Phelps from the bereavement list.

Phelps was away for a few days following a death in the family. The Marlins have discussed moving him into the rotation, but he'll presumably return to the bullpen for now.
May 26 - 8:13 AM

Marlins placed RHP David Phelps on the bereavement list.

Phelps will miss the Marlins' two-game series against the Athletics following a death in his family. The 30-year-old right-hander has posted a cool 3.68 ERA and 24/8 K/BB ratio in 22 innings of relief this season for Miami and could soon move into the starting rotation.
May 23 - 4:59 PM

David Phelps is a candidate to start Sunday against the Dodgers.

Odrisamer Despaigne is also being considered. The Marlins need someone to take the place of Tom Koehler, who was placed on the DL with shoulder inflammation. Despaigne started in the minor leagues before his call-up while Phelps has amassed 64 big league starts including five last season. Phelps isn't stretched out so he'd probably be limited to four or five innings if he gets the call on Sunday.
May 18 - 10:53 PM

Marlins manager Don Mattingly hinted Wednesday that the organization is considering moving David Phelps from the bullpen into the starting rotation.

There's a serious starting pitcher crunch on the Marlins' roster with Wei-Yin Chen fighting an elbow injury and Adam Conley and Tom Koehler both sitting at Triple-A New Orleans due to ghastly results in Miami. Mattingly said if the Marlins make Phelps a starter, they'll keep him a starter for the remainder of the year. The right-hander has been sharp over the last three weeks after struggling for a bit in early-to-mid April and makes for a worthy stash in deeper mixed fantasy leagues. Phelps holds a 2.64 ERA, 1.17 WHIP, and 134 strikeouts over his last 105 2/3 innings with Miami.
May 17 - 10:51 AM

David Phelps surrendered four runs in two innings to take a loss in relief Friday against the Padres.

Phelps was a monster out of the pen last year, but he's already given up three homers in 10 innings this season after allowing just six in 86 2/3 innings in 2016. On the plus side, he's struck out 12 with no unintentional walks (two IBBs) to date. He still figures to be a valuable reliever for the Marlins.
Apr 22 - 1:01 AM

David Phelps won his arbitration case against the Marlins and will make $4.6 million in 2016.

Miami's front office had filed at $4.3 million in January. It's a well-deserved raise for the 30-year-old right-hander, who registered a stellar 2.28 ERA and 114/38 K/BB ratio in 86 2/3 innings (five starts, 59 relief appearances) last season for the Marlins. Barry Jackson of the Miami Herald says Phelps attended the arbitration hearing, though that's not really an uncommon thing. He'll have one more year of arbitration in 2018 before hitting free agency.
Feb 9 - 1:46 PM

David Phelps' arbitration hearing with the Marlins has been set for February 8.

Phelps, who broke out with a 2.28 ERA and 114/38 K/BB ratio in 86 2/3 innings across five starts and 59 relief appearances in 2016, required $4.6 million and was offered $4.325 million when arbitration figures were exchanged earlier this month. The arbitration panel will rule on one salary or the other for the 2017 season.
