The 32-year-old, coming off a season in which he missed some time after being hit in the head by teammate Giancarlo Stanton's shot during live batting practice, just completed a seven-year, $155 million deal.

A two-time All-Star selection, Tanaka spent all seven of his MLB seasons as a Yankees starter from 2014 to 2020 and was one of the most consistent starting pitchers in the majors over that span, going 78-46 in 173 starts.

He posted a 3-3 record with a 3.56 ERA -- down from 4.45 in 2019 -- in 10 starts during the pandemic-shortened 2020 season.

Tanaka was found to have a partially torn ligament in his pitching elbow during the 2014 season, and from then on, the Yankees tried to give him extra rest between starts at times. He made a $22 million base salary in both the 2018 and 2019 seasons and $23 million in 2020.

He pitched well in the playoffs during his time in the Bronx, going 5-4 with a 4.18 ERA, 44 strikeouts and 15 walks in 10 starts and 54 innings. He had his best postseason run in 2017, when he went 2-1 with a 0.90 ERA, 18 strikeouts and three walks in 20 innings during the division series against Cleveland and American League Championship Series versus Houston.

Prior to joining the Yankees, Tanaka was 99-35 with a 2.30 ERA in seven seasons with the Rakuten Golden Eagles, striking out 1,238 in 1,315 innings.
