Kyle Harrison, SP, San Francisco Giants

Kyle Harrison is the number one prospect in the Giants system and 20th overall in MLB. The 22-year-old lefthander is getting added everywhere after he pitched a gem against the Cincinnati Reds. He struck out 11 batters across 6.1 shutout innings and earned his first career win.

Harrison relies heavily on his fastball, which averages 94.4 miles per hour. He throws the pitch 69.9% of the time. His second most used pitch is a slurve; he pitches it 23.7% of the time. The lefty has recorded a negative five-run value with the slurve. A changeup, cutter, and slider make up the final 6.3%.

Harrison's next start comes on Saturday, September 2, versus the San Diego Padres. Then, after that, he faces the Colorado Rockies on Friday, September 8. Fantasy managers should add Harrison and start him for both of these games.

DJ Stewart, OF, New York Mets

DJ Stewart has been one of the hottest batters in baseball over August. He slashed .303/.378/.727 in August with eight home runs, ten runs, and 16 RBI. His season line increased to .279/.364/.651 with a 172 wRC+.

During this stretch, he mostly batts sixth or seventh in the lineup. Stewart has recorded a 50% hard-hit rate in this span with a 15.2% barrel rate. He is averaging 50.8% and 16.9% on the season, respectively. Fantasy managers can expect the lefty slugger to continue belting extra-base hits.

The Mets have two off days this week, limiting Stewart's value, but they have easier pitching matchups on three days. These games are against MacKenzie Gore, Patrick Corbin, and Dallas Keuchel. Stewart needs to be starting in Fantasy lineups on these days.

Jasson Dominguez, OF, New York Yankees

MLB's number 77 prospect, Jasson Dominguez, debuted for the New York Yankees on Friday, September 1. He went 1-for-4 with a home run against the Houston Astros.

Dominguez played 109 games in Double-A before getting the call up to Triple-A, where he played nine games. He combined for a .265/.377/.425 slash line with a 121 wRC+. He belted 15 home runs, three triples, and 22 doubles, scoring 89 runs and 76 RBI. Dominguez added 40 stolen bases, too.

The rookie is a switch hitter and power/speed combo, as highlighted by his 60+ raw power grade and 60 speed grade. Dominguez can potentially be an absolute star in Fantasy Baseball, resembling the likes of Ronald Acuna Jr. and Bobby Witt Jr. Add him in 12-team leagues where he's still available.

Gabriel Moreno, C, Arizona Diamondbacks

A player I was excited about this season is the catcher, Gabriel Moreno. The Diamondbacks acquired the catcher from the Toronto Blue Jays in exchange for Daulton Varsho this past offseason. Moreno was rated as a top-10 prospect in 2022.

The Diamondbacks recalled Moreno on August 13; since then, he's slashed .327/.365/.612 with a 161 wRC+. In these 14 games, Moreno has scored nine runs and 12 RBI.

It hasn't been all sunshine for the rookie catcher, however. In his first 244 plate appearances, he slashed .270/.316/.360 with 17 runs, 28 RBI, and 84 wRC+. Moreno is easily playing his best stretch of baseball. In the past 14 games, he is averaging a 53.7% hard-hit rate. Before this stretch, he averaged a 39.3% hard-hit rate.

For teams needing a catcher down the stretch, look no further than Moreno. He is the catcher to target this week. He's recorded 40 at-bats over the last 15 days, ranking ninth among catcher-eligible players. His 1.070 OPS in the span is better than the eight players above him.

Davis Schneider, 2B, Toronto Blue Jays

Arguably, the biggest late-season breakout of 2023 is Davis Schneider. The second baseman made his MLB debut on August 4 and went 2-for-5 with a solo home run. He then went 7-for-8 in his next two games with two runs and four RBI.

However, Schneider has played his best baseball over the last six games. In this stretch, he's gone 10-for-21 with seven extra-base hits, eight runs, and nine RBI. He recently earned playing time as a third baseman, outfielder, and designated hitter.

Schneider has also been hitting the ball harder over this recent stretch of games as he's averaged a 50% hard-hit rate, compared to a 31.3% over his first eight games.

Schneider gets to play two weak pitching staffs this week. The first is the Oakland Athletics, and the second is the Kansas City Royals. He is one of the best options in Fantasy Baseball leagues this week.

Ronny Mauricio, SS, New York Mets

Lastly, Ronny Mauricio makes the list after making his MLB debut on Friday against the Seattle Mariners. MLB.com ranks Mauricio as the 90th overall prospect and the Mets' fourth-best prospect. During his debut, Mauricio went 2-for-3 with a strikeout against the Seattle Mariners.

Mauricio played 116 games in Triple-A this season. He slashed .292/.346/.506 with 23 home runs, three triples, 30 doubles, 76 runs, and 71 RBI. The Shortstop added on 24 stolen bases, too.

Mauricio is a power-first bat with decent speed to match. He won't get as many stolen bases as Dominguez, but he should still get plenty of extra-base hits to provide value.
