It's still grading out as a pitcher's park (19th in baseball in runs) this year, and it's not finished higher than 19th in any season. That said, this is not a "park factor" statistic. It's a runs allowed statistic. Yankee stadium grades out as a hitter's park easily, yet it's often lower in runs scored because the Yankees typically have solid pitching. Baseball-reference uses a grading system on all parks with a 100 score being average (explained here), over 100 being hitter friendly, and under 100 being pitcher friendly. This season the batter/pitcher average is 99, the multi-year grade is 97. While year to year grades will show plenty of variance, the multi-year grade often is very true to form. Target Field is the 10th most pitcher-friendly park in that statistic, ranking behind your assumed parks (Seattle, San Francisco, Los Angeles (both of them), San Diego, etc., but also ranking as more of a pitcher's park than some assumed pitchers' paradises like Washington, Oakland, and Atlanta. To compare, Yankee stadium is the 6th most hitter-friendly park according to B-Ref's park adjustments, but they're 16th in runs scored this season. Terms like "pitcher-friendly" or "hitter-friendly" cannot be simply evaluated with home runs or runs scored. Coors Field is incredibly hitter friendly, but it has some of the largest dimensions of any field in the game, which would on the surface look pitching friendly. However, the thinner air and huge outfield hurt pitchers as line drives often take different routes in the Colorado air and can cut through and out of the park where they'd often die due to air friction in a similar-sized park closer to sea level.
