Saucedo (knee) struck out one over a scoreless inning Thursday in his first rehab appearance with Triple-A Tacoma. Saucedo landed on the 15-day injured list a little over two weeks ago with a hyperextended right knee. Because he hasn't missed much time, the left-handed reliever shouldn't need more than a couple rehab appearances, setting himself up for a return within the next few days.
Castillo (4-6) took the loss Thursday against the Yankees, allowing two runs on seven hits and three walks over five innings. He struck out three. Castillo dealt with traffic for most of his outing, he'd ultimately hold New York to a pair of solo home runs. The loss snapped a stretch of seven straight quality starts for Castillo -- he'd posted a 2.01 ERA in that span. Overall, his ERA sits at 3.31 this season with a 1.21 WHIP and 69:18 K:BB over 65.1 innings. Castillo's currently lined up for a home matchup with the Astros in his next start.
Peralta was designated for assignment by the Mariners on Thursday, Daniel Kramer of MLB.com reports. Seattle has scooped up Eduardo Salazar off waivers from the Dodgers and Peralta is the 40-man roster casualty. Peralta, 26, has spent all of this season at Triple-A Tacoma, putting up a 9.24 ERA and 12:8 K:BB over 12.2 frames.
The Mariners optioned Bolton to Triple-A Tacoma on Thursday. Bolton will cede his spot on the 26-man roster and in the bullpen to right-hander Mike Baumann, whom the Mariners acquired from the Orioles on Wednesday. In 15 relief appearances for Seattle this season, Bolton has compiled a 4.41 ERA and 1.29 WHIP across 16.1 innings in relief.
Haniger is out of the lineup for Wednesday's game against the Yankees. Haniger will hit the bench for the second time in the series, and he could find himself in more of a part-time role or short-side platoon role moving forward after the Mariners recently welcomed Dominic Canzone back from the injured list. With Canzone and the hot-hitting Luke Raley having made cases for regular roles in the corner outfield, Mitch Garver could represent Haniger's primary competition for playing time at designated hitter. Haniger has turned in an underwhelming .587 OPS in May and is slashing .217/.280/.361 overall on the season.
Rodriguez will start in center field and bat sixth in Thursday's contest versus the Yankees. For the first time this season, Rodriguez won't be batting either first or second for Seattle. Rodriguez is hitting .325/.357/.425 over his last 10 games but has gone just 1-for-12 at the dish in the first three games of the series against the Yankees. He's sporting a disappointing .630 OPS on the season.
Polanco is out of the lineup for Thursday's game against the Yankees. After missing seven consecutive starts due to a right hamstring injury, Polanco made his return to the lineup in Wednesday's 7-3 loss, starting at second base while going 0-for-4 with a strikeout. The Mariners haven't indicated that Polanco experienced a setback with his hamstring Wednesday, so his absence Thursday is likely just a matter of maintenance due to the quick turnaround for the series finale, which begins at 12:35 p.m. ET. Dylan Moore will fill in for Polanco at the keystone.
Raleigh is absent from the lineup for Thursday's game versus the Yankees. Raleigh started the first three games of the series against the Yankees and hit a home run in Wednesday's 7-3 loss, but he'll get a breather for Thursday's afternoon tilt. Seby Zavala will draw the start at catcher.
