Fantasy Baseball Player Notes

Santander has quietly turned into a strong power bat, but few fantasy managers seem to give him credit. A .476 slugging percentage with 20 home runs in 93 games in 2019, followed by a .575 slugging percentage and 11 home runs in 37 games in 2020. There's nothing particularly fluky about his power output - it's just a young hitter coming into his own and making better contact. He did seem to sell out a bit for power last year, upping his launch angle and fly ball rate significantly. And yet he hit .261, the same mark as in 2019, and his xBA was .286. In other words, there's plenty to like about Santander, who is going well behind other hitters who offer similar production. He should be a value in drafts this year.

Mountcastle followed up a successful minor-league career with a strong 35-game stint in the majors last year. Not only did he bat .333 with an .878 OPS and a 139 wRC+, but he also walked 7.9% of the time, far above what he showed in the minors. The batting average is unsustainable - he was a .295 hitter in the minors and last year he relied on a .398 BABIP despite sub-par average exit velocity and a middling line drive rate. But playing in Camden Yards should certainly keep his production high, and batting in the middle of the Orioles lineup should lead to enough RBI chances to make him a rosterable, if not startable, fantasy option.

Mancini missed all of the 2020 season after being diagnosed with cancer, but appears to be healthy as we head into 2021. He had a breakout 2019 season during which he hit 35 home runs and slashed .291/.364/.535, and there's every reason to think that production is sustainable. Mancini had hit 24 home runs in each of the two previous seasons, and other than being a bit more selective at the plate, made few changes that suggest his 2019 production was fluky. Instead, it appeared to be the natural progression of a hitter improving on his already strong foundation. Batting in a great home park, Mancini should again be a four-category producer, and his ADP should rise if he shows he's fully healthy throughout the spring.
