2021 Fantasy Outlook
Even as the grandson of a Hall of Famer, Yastrzemski has had his doubters, but he quieted those doubters with a brilliant 2020 season. Yastrzemski finished seventh among MLB hitters in fWAR (2.7) and finished as OF15 in rotisserie leagues. He was far more patient at the plate than he was during his rookie season, cutting his Swing% from 47.1% to 38.9% and upping his walk rate from 7.8% to 13.3%. It's great to see that even as he was taking more pitches, he was still all over the hittable pitches that were in the strike zone. His Statcast numbers are all over the map as Yastrzemski ranked in the bottom 40th percentile in hard-hit rate and the expected stats say he was out over his skis, but at the same time his xwOBA and xSLG were in the top 20% of the league. He is already 30 and not a great athlete, but Yastrzemski is now the face of the Giants and the recent changes at Oracle Park have helped offense. Read Past Outlooks

September 24, 2021
Yastrzemski was removed from Friday's game against the Rockies due to right knee soreness, Susan Slusser of the San Francisco Chronicle reports.
ANALYSIS
Yastrzemski went 1-for-3 with a three-run homer, a walk and a strikeout to begin Friday's contest, but he was replaced defensively in the bottom of the ninth inning. He's considered day-to-day, and Steven Duggar and Austin Slater could see increased playing time if the 31-year-old is forced to miss additional time.

2020 Fantasy Outlook
Yastrzemski finally broke into the majors in 2019 after being traded from the Orioles to the Giants prior to the season. The outfielder got off to a slow start following his promotion in May, but he found his groove after the All-Star break and posted a 136 wRC+ over 70 second-half games. Yastrzemski's 21 homers -- which came in just 371 at-bats -- tied for most on the Giants, while his .852 OPS and 121 wRC+ led all players on the team with at least 200 plate appearances. Although Yastrzemski could stand to improve his approach (7.8 BB%, 26.0 K%), his strong batted-ball profile suggests his success is for the most part believable. Yastrzemski was shielded pretty heavily against lefties in his debut season, though he performed well enough in his limited opportunities (.943 OPS in 89 PA) to potentially earn more at-bats against southpaws in 2020. Either way, he should remain a fixture in the lineup.
