17 Adam Warren RP

Warren signed a one-year deal with the Padres on Friday that includes a club option for 2020, Kevin Acee of The San Diego Union-Tribune reports.

Warren started 2018 with the Yankees but was traded to the Mariners in July, and compiled a 3.14 ERA, 1.32 WHIP and 52:20 K:BB across 51.2 innings for the season. The 31-year-old seems likely to start out in a middle-relief role in San Diego, but according to Emily Waldon of The Athletic, the deal includes performances bonuses that would trigger if he's used as a starter, so the club could be planning to try him out in that role. Warren's last start in the majors came in 2016 with the Cubs, and was his lone start over 58 appearances that season.

Warren was dealt to Seattle in exchange for international bonus pool money on Monday, Ken Rosenthal of The Athletic reports.

The Mariners acquired a second reliever in the span of an hour after trading for Zach Duke from the Twins earlier. Warren has missed some time due to a back injury this year, but has appeared in 24 games for the Yankees nonetheless. Across 30 innings, he's logged a 2.70 ERA and 1.27 WHIP with a 37:12 K:BB, though he has allowed six earned runs in 10 innings of relief this month. Look for him to take on a late-inning role with the Mariners.

Warren (back) was activated from the 10-day disabled list ahead of Game 2 of Monday's doubleheader against the Tigers.

Warren hasn't pitched since April 20 due to a back injury, but he's been cleared to return after getting through three scoreless innings in his final minor-league rehab appearance last week with no issues. He'll take the roster spot of Tommy Kahnle, who was sent to the minors in a corresponding roster move. Prior to landing on the shelf, Warren compiled a 3.24 ERA and 11:4 K:BB across 8.1 innings of relief this season.

Yankees manager Aaron Boone said that Warren (back) could be activated ahead of Monday's doubleheader with the Tigers, Brendan Kuty of NJ.com reports.

Warren was stellar Wednesday in his second rehab outing at Double-A Trenton, striking out three over three scoreless innings while yielding just one hit. Now that he has had a few days to recover from that elongated relief appearance, Warren looks ready to return from the DL, but it's possible the Yankees decide to wait on the transaction since the bullpen hasn't been overworked of late.

Manager Aaron Boone said Warren (back) won't be activated during the Yankees' series against the Orioles over the weekend, Bryan Hoch of MLB.com reports.

Warren allowed just one hit and struck out three across three scoreless innings in his second rehab appearance, this one with Double-A Trenton. While it was a drastic improvement from his first rehab outing, it sounds like the Yankees want him to get one more tuneup in before likely rejoining the big club sometime next week.
