What Should We Make of Jesse Winker?
Here is an understatement: Jesse Winker had a pretty solid weekend. On Friday, he collected four hits, including three home runs, and a walk. On Saturday, he only went 1-for-4, but added another homer. And on Sunday, he homered again, bringing his weekend total to five and his season total to 13. His wRC+, which entered the weekend at a cool 166, jumped 26 points to 192; by this metric, he’s now the third-best hitter in baseball. His .463 wOBA, meanwhile, ranks first.
To say that Winker has broken out this season would be inaccurate. He has always been a very good hitter, particularly against right-handed pitching. Plus, his numbers have seen a significant uptick over a fairly large sample. In short, it’s not just 2021: Over his last 162 games, dating back to May 22, 2019, he is hitting .306/.401/.563 with 31 homers. In that span, he has been the seventh-best hitter in the majors by wRC+, at 154.
He really put everything together during his 2020 season, with his once-extreme platoon splits (we’ll get to those in a moment) dissipating in the shortened campaign. His 146 wRC+ was a “seasonal” career-high, and his .289 ISO was eye-popping for a hitter who had posted sub-.200 marks for his career to that point. Winker, who had rarely been considered a power hitter — he graded as having 30 game power in his last prospect scouting report back in 2018 — posted the same 2020 ISO as Teoscar Hernández.
Winker’s 2020 season did turn heads, as did his hot start to 2021. But we’re admittedly still dealing with small-ish samples for this new slugging version of him. His ISO, which was only .181 going into 2020, is .320 so far this season. And we’re starting to see the projection systems more fully buy in. Here are the largest rest-of-season ZiPS ISO increases, compared to the pre-season projections:
