De Jong was optioned to Triple-A Tacoma on Friday, Ryan Divish of The Seattle Times reports.
After hurling four innings in relief Thursday, the Mariners will send De Jong back to the minors in order to replenish their depleted bullpen. Zac Curtis will take his place in the bullpen, although this strong outing for De Jong could land him a return trip to the big leagues whenever a fresh arm is needed.
De Jong fired four scoreless innings in Thursday's 6-2 loss to the Twins, allowing one hit and two walks while recording two strikeouts.
The 23-year-old cruised through his four frames on 54 pitches, allowing just a double to Kennys Vargas. De Jong is expected to serve as a long-relief option for the time being, although he's always available to start in a pinch. Factoring in Thursday's outing, he's generated a 6.35 ERA and 13:13 K:BB over 28.1 innings at the major-league level this season.
De Jong was recalled from Triple-A Tacoma on Wednesday, Bob Dutton of The Tacoma News Tribune reports.
De Jong will provide the Mariners' bullpen with a fresh for Wednesday's game against the Twins, replacing Casey Lawrence, who was optioned to Tacoma after giving up six runs in 3.2 innings of relief in Tuesday's 20-7 loss. The right-hander has previously made six appearances (four starts) for the Mariners, submitting a 7.40 ERA and 1.68 WHIP over 24.1 innings.
De Jong threw six scoreless innings in Triple-A Tacoma's 1-0 win over Reno on Thursday, giving up three hits and three walks while recording seven strikeouts.
De Jong had been hit hard in his first three starts since returning from the big-league club, giving up 14 earned runs on 21 hits and two walks in 17 innings across three starts. Therefore, Thursday's effort was a welcome sight and served as his best of the season overall. The 23-year-old right-hander has a 4.32 ERA, 1.23 WHIP, .237 BAA and 34:10 K:BB across 33.1 innings over six starts for the Rainiers.
De Jong dealt six innings, allowing four runs on seven hits and three walks while striking out four in a no-decision Tuesday against Oakland.
The A's punctured the scoreboard with a pair of runs in the second and fourth innings, but De Jong actually lowered his season's unsightly ERA to 7.40 with Tuesday's effort (four starts and two relief appearances). As a starter this year, the rookie has surrendered 17 runs over 19.2 innings while opposing hitters have battered De Jong to a .321/.385/.549 slash line. He's also served up four home runs while owning a 9:8 K:BB working out of the rotation. De Jong is scheduled to make his next start Sunday versus the White Sox.
