Seattle Mariners infield prospect Colt Emerson carries high-end stash upside among hitting prospects as he is on the verge of making his MLB debut. Earlier this season, Emerson inked a massive eight-year contract and was later added to the 40-man roster, but has yet to earn the call. Through his first 18 games of the Triple-A regular season, the former 22nd overall selection has posted a solid .258/.361/.452 line with a .813 OPS. During this stretch, Emerson has launched two home runs and added six doubles with six stolen bases. Last summer, Emerson spent most of his time with High-A and Double-A, where he carried .280/.380/.444 line over a 124-game stint. When he does earn the call, Emerson could see time at second base, third base, or shortstop, which could shift Brendan Donovan to left field or limit Cole Young's and J.P. Crawford's at-bats.

Miami Marlins left-handed pitching prospect Robby Snelling continues to impress at Triple-A and is knocking on the MLB door. This weekend, Snelling turned in another dominant showing at Triple-A Jacksonville, tossing six shutout frames with two hits and one walk while striking out nine batters. In his previous outing, Snelling looked just as sharp, striking out a season-best 12 hitters over five shutout frames. Overall, through his first four outings of the young season, the southpaw has struck out 31 hitters while holding a 1.89 ERA and a 0.95 WHIP over 19 innings. Last summer, Snelling looked just as comfortable in his first stint at Triple-A, holding a 1.27 ERA and a 0.99 WHIP across 63 2/3 innings. Given his impressive production at the top level of the minor leagues, Snelling holds elite stash value in all standard leagues ahead of Week 4.

Detroit Tigers outfield prospect Max Clark continues to perform at an elite level at Triple-A and is quickly approaching his MLB debut. Through his first 19 games at the top level of the minor leagues, Clark has posted a .351/.416/.519 slash line with eight doubles, one triple, one home run, six stolen bases, and a 10:10 K:BB. Last summer, Clark spent most of his time with High-A before joining Double-A in the second half. Across both levels (111 games), the former third overall selection looked just as sharp, carrying a .271/.403/.432 line with an .835 OPS, 14 home runs, and 19 stolen bases. While the Detroit outfield is crowded at the moment, following the promotion of Wenceel Perez, Clark's current trajectory could push the team's hand. For now, he is a top stash option in 12+ team, five-outfielder leagues.

Colorado Rockies first base prospect Charlie Condon is not slowing down at Triple-A and continues to make a strong case to join the MLB roster in the near future. While he was given an opportunity to win a starting job out of camp, the Rockies opted to send him to Triple-A to further his development. However, throughout his first taste of the top level of the Rockies system, Condon has looked very impressive and has proven he is more than ready to face MLB pitching. Through his first 15 games with Albuquerque, the former Georgia standout has posted a .322/.452/.559 line with two doubles, four home runs, two stolen bases, and a strong 13:12 K:BB. Additionally, following a hot start to the season, current starting first baseman, TJ Rumfield, has gone just 2-for-24 over his last six games. As a result, Condon should be viewed as a priority stash option in all leagues in Week 4.
