If you want to win your 2023 Fantasy baseball league and bring home a championship this season, you'll need to crush your 2023 Fantasy baseball drafts. Players like Mike Trout, Aaron Judge and Mookie Betts are no-brainers, but correctly identifying which undervalued players are poised for big seasons can help lead you to a Fantasy baseball championship. That means a reliable set of 2023 Fantasy baseball rankings will be absolutely critical when deciding which players to select on draft day.

A good set of Fantasy baseball rankings 2023 will help you find the best values at the top of Fantasy baseball drafts. But they can also help you dominate throughout the entire selection process, identifying potential 2023 Fantasy baseball sleepers at every position. Before finalizing your 2023 Fantasy baseball draft prep, be sure to see the 2023 Fantasy baseball rankings and cheat sheets from the proven computer model at SportsLine.

Last season, SportsLine's Projection Model identified several top Fantasy baseball sleepers, breakouts and busts, including Cardinals second baseman Tommy Edman.

Edman had a 2022 Fantasy baseball ADP well outside the top 100 but the model predicted that he'd outperform that draft position. The result: Edman posted new career-highs in home runs (13), RBI (57) and stolen bases (32) while slashing a respectable .265/.324/.400 to finish as the third-best second baseman in Fantasy baseball. Anybody who followed its advice and picked up Edman late in their Fantasy baseball drafts received a huge power boost in their Fantasy baseball lineups.

The SportsLine model is engineered by the same people who powered projections for all three major Fantasy sites. And that same group is sharing its 2023 Fantasy baseball rankings and cheat sheets over at SportsLine, helping you find Fantasy baseball sleepers, breakouts and busts long before your competition. Their cheat sheets, available for leagues on many major sites, are updated multiple times every day.

Top 2023 Fantasy baseball sleepers

One of the Fantasy baseball sleepers 2023 the model is high on: Orioles left fielder Austin Hays. He played a career-high 145 games last season, racking up a career-best 134 hits at a .250 clip. Hays has hit a combined 38 home runs over the last two campaigns to go along with 62 walks and 131 RBI.

He hit .333 through his first 14 Grapefruit League games this year, with four of those hits leaving the yard. Hays added 10 RBI and scored six runs, confirming the assumption that he will open the season as Baltimore's starting left fielder. He is currently being selected behind Ian Happ, Corbin Carroll and Chris Taylor in average drafts, but SportsLine's model has him ranked ahead of those left fielders.

Another of the Fantasy baseball sleepers 2023 the model is all over: Mariners starting pitcher Luis Castillo. The right-hander was efficient with the Mariners after the Reds traded him shortly before the deadline last season, recording a 3.17 ERA, 77:17 K:BB and 1.10 WHIP over 65.1 innings.

Castillo will be the ace in Seattle's pitching staff this season, and he'll get the start on Opening Day when the Mariners host the Guardians. Castillo has recorded at least 165 strikeouts in four of his last five seasons, the lone blemish being the shortened 2020 MLB season. Those impressive numbers are a big reason why the model ranks Castillo (fifth-round ADP) ahead of pitchers like Shane Bieber, Brandon Woodruff and Corbin Burnes, three players being drafted ahead of Castillo.

How to find proven 2023 Fantasy baseball rankings

This pick could be the difference in winning your league or going home with nothing. You can only see who it is here.
