2021 Fantasy Outlook
Save for a 10-day stretch in early August when he was optioned to the alternate training site, Mayfield spent the season serving as a reserve infielder for the Astros, playing sporadically. When he saw action, Mayfield struggled, fanning at a 29.8% clip while walking only 4.3% of the time. The power Mayfield flashed in 2019 with Triple-A Round Rock disappeared with the lively ball as he managed just one extra-base hit, a double, in 42 trips to the dish. Houston designated Mayfield for assignment in November and he was subsequently claimed by Atlanta. The Braves' middle infield is set with Ozzie Albies and Dansby Swanson, so if Mayfield latches on, he'll be a little-used backstop with no fantasy allure. Read Past Outlooks

Swipes two bags Sunday
SSLos Angeles Angels
October 4, 2021
Mayfield went 2-for-4 with a walk, an RBI and two stolen bases in Sunday's 7-3 victory versus the Mariners.
ANALYSIS
Mayfield was one of three Angels to knock multiple hits in the season finale, and he plated the team's second run with an infield single in the first inning. The 31-year-old began the campaign in the minors and was DFA'd by both the Angels and Mariners during the season. However, he became a bright spot for Los Angeles after he latched back on with the club in mid-June, eventually claiming a role as the club's starting third baseman. Mayfield collected at least one hit in 11 of his final 12 contests, slashing .280/.315/.400 with a home run, 11 RBI and three stolen bases over that stretch.

2020 Fantasy Outlook
The Astros, briefly down both starting middle infielders and missing utility man Aledmys Diaz, were forced to turn to Mayfield for 16 starts last season (12 at shortstop, four at second base). Mayfield held his own in the field but struggled mightily at the dish, striking out in roughly a quarter of his plate appearances while walking only once. He hit 26 home runs in just 100 games at Triple-A, but the happy fun ball is mostly to thank for that. From 2017-18, Mayfield totaled 22 homers at Triple-A and was pretty much exactly league average while being old for the level at ages 26 and 27. As of mid-December, Mayfield was still a member of the Astros' 40-man roster, but he's certainly no lock to survive the winter with his spot. Even on a bottom-feeding team, he'd only be a part-time/depth player.
