SEATTLE -- Los Angeles Angels star Shohei Ohtani said Sunday he is "very open" to negotiating a long-term contract with the club this offseason.

Ohtani spoke before the Angels' regular-season finale in Seattle. Ohtani could have pitched on turn on the final day of the season but opted to skip his final start. He was the designated hitter and leading off in the Angels' lineup for the last game of a possible AL MVP season.

"Of course, I'll be very open to negotiation. The team is supporting me for this whole four years, and I'm really appreciative of that," Ohtani said through an interpreter. "Whether or not there's any contract extensions I just want to, like I said earlier, be ready and be ready for next season."

Ohtani finished his fourth season with the Angels and is signed to an $8.5 million, two-year contract that pays $5.5 million next year in its final season. He is eligible for salary arbitration after the 2022 season and free agency following the 2023 season if the rules do not change following the expiration of the collective bargaining agreement on Dec. 1.

Ohtani is the presumptive leader in the AL MVP race after going 9-2 with a 3.18 ERA in 23 starts on the mound, and hitting 46 home runs at the plate.

"I was really happy to get through the season without any injuries," Ohtani said. "And honestly, I wish I could have done a season like this a little earlier. This is my fourth year, so I think it took a little too long."

But the team performance on the field hasn't matched Ohtani's aspirations when he arrived from Japan's Hokkaido Nippon Ham Fighters in 2018. The Angels finished in fourth place in the AL West for the fourth straight season, besieged by injuries to Mike Trout and Anthony Rendon. Los Angeles has yet to post a record above .500 since Ohtani arrived.

"I think the biggest thing is the guys that we have right now, we need to have an offseason so we can stay healthy the whole next year so we could compete," Ohtani said. "Any addition during the offseason, I'll be looking forward to seeing all the additions that they're going to make."
