Pittsburgh Pirates
2025 Fantasy Outlook
Horwitz was one of the few bright spots on a disappointing Toronto roster as he came up and more than handled his own in his rookie season at the plate. Horwitz earned his promotion with a .335/.456/.514 triple-slash line in 57 games in Triple-A Buffalo where he walked more often than he struck out. He finished the season with the Jays hitting .265/.357/.433 with 12 homers and a willingness to accept walks. Those numbers were mostly put up against righties because he did not hit lefties well. All 16 of his homers came off righties, as he hit .310/.416/.522 against them but had just six doubles and a .244/.340/.291 line against southpaws. He has both first- and second-base eligibility for fantasy purposes, but Horwitz figures to be done playing second base after a series of offseason trades led to him ending up atop Pittsburgh's first-base depth chart. He is likely to sit against most lefties when the Pirates are at full strength, but he has a high floor against right-handed pitching, especially after getting traded to this less crowded situation.

Analysis
Horwitz will take a seat for the Pirates' season finale, giving way to Rafael Flores at first base. Assuming Horwitz doesn't enter off the bench, he'll end the campaign with a .273/.354/.435 slash line, 11 home runs, 51 RBI and 55 runs scored across 410 plate appearances.

Past Fantasy Outlooks
2024
2023
Horwitz has been an accomplished hitter all throughout the Toronto system with a .303/.407/.464 triple-slash line in just over 1,700 plate appearances since 2019. He is the type of hitter that is both accepting of his walks as well as someone very willing to use his contact skills to put the ball in play having never struck out as many as 80 times in a season at a time where many minor leaguers are posting triple-digit strikeout totals. Horwitz's 2024 fantasy value is clouded in two ways. Primarily, he is only eligible at utility on draft day as he had six games at DH and five at first base last season. Secondarily, the Jays roster is rather loaded with talent and Horwitz's best path forward would be playing left field. If he were to get that job, he would still likely hit in the 9th spot of the lineup.
Horwitz had a .293/.409/.513 slash line with Double-A New Hampshire during the first half of 2022 to receive a promotion to Triple-A Buffalo, where he had a .724 OPS. Trading Teoscar Hernandez to the Mariners opened up significant at-bats between right field and designated hitter for the Blue Jays, but there's still not an immediate path to the majors for Horwitz. He saw most of his action last season between first base and left field, but his limited power (.117 ISO) could limit his potential at first base. The 25-year-old continued to show excellent plate discipline with a 15 percent walk rate, which would obviously translate well to any position in the majors. Horwitz is likely to begin 2023 back with Buffalo, but he could quickly be called up for his big-league debut with a strong start to the season.

Latest Fantasy Rumors
Pirates debut coming soon?
1BPittsburgh Pirates
April 28, 2025
Horwitz in inching closer to making his 2025 season debut, as he began a rehab assignment over the weekend.
Analysis
The 27-year-old has yet to play this year after undergoing wrist surgery in February, but he's currently on a minor-league rehab assignment with Double-A Altoona. He's expected to play in several games before being promoted to the majors. Horwitz should provide an offensive boost from first base once he's called up. In parts of two seasons with the Blue Jays between 2023 and 2024, he slashed .264/.355/.428 with 13 home runs and 21 doubles in 425 plate appearances.
