The deal includes a full no-trade clause and doesn’t contain an opt-out clause, sources said. He is tentatively scheduled to undergo his physical Friday and be introduced at Angel Stadium on Saturday.
The 31-year-old put up a 4.91 ERA/5.14 FIP with 9.05 K/9, 5.68 BB/9 and a 42.8 percent grounder rate during an injury-limited, 58 2/3-inning showing (2019). He also blew five saves on 23 attempts, which led the A’s to strip him of the closer role and hand it to Liam Hendriks. Furthmore, Treinen saw his swinging-strike rate fall by almost 6 percent and his home run-to-fly ball rate climb by 12 percent.
