Wow! What a Trade Deadline that was, we saw an immense amount of trades happen. Not only just a lot of trades but there was also a ton of top-tier-talent changing teams.

Matt Thaiss, 1B, Los Angeles Angels

The former 16th overall pick in the 2016 MLB Amateur Draft was once the Angels' fifth-ranked prospect prior to debuting in 2019.  While he did lose his prospect eligibility in 2019, he is still very much a young and unproven prospect.

During his debut season, he ended with a slash line .211/.293/.422 with eight home runs, 23 runs batted in, and 17 runs scored in only 164 plate appearances.

Thaiss did have a tiny cup of coffee in 2020 as well but only appeared in eight games. In his eight games, he did have one home run but only managed to hit .167.

He has always had an advanced bat, even dating back to his time at the University of Virginia, where he hit .339 and had an OPS of .948. Then followed that by hitting .280 across four levels of the minors.

However, he features more hit over power batted ball profile. As he has never had more than 25 home runs in a season and his career-high is 24 home runs.

Matt was recalled this past week when Jared Walsh hit the IL, however, his promotion didn't last long as he was sent back down yesterday.

Reid Detmers, LHP, Los Angeles Angels

One of the best college arms in the 2020 draft class has proven why he was worth the first-round pick. Reid was drafted 10th overall in the 2020 draft by the Angels.

He features a slid four-pitch mix of fastball, curveball, slider, and change-up. He uses his mid 90s fastball to set up hitters. While his curveball is his best secondary pitch, he continues to develop the change-up as he recently added it after being drafted.

Detmers has above average strikeout upside. Even dating back to his time at Louisville, when he struck out 284 batters in 191IP. While there wasn't a minor league season in 2020, there were a lot of reports of Detmers dominating at the Alternate Training site.

He continued his dominance this year at Double-A and was quickly promoted to Triple-A, continuing to mow down batters at a 42 percent rate. Including a two-game stretch in late June when he struck out 30 batters in 12 innings.

Detmers was called up ahead of his start this past Sunday to make his major league debut against Oakland. Unfortunately, it was not the start that Detmers had been hoping for. He allowed six runs on six hits and gave up two long balls. Not only that but he only struck out two batters and allowed two free passes.

Even with the struggles in his first start. I would be adding Detmers, even in shallow leagues. He has huge strikeout potential and should be able to bounce back and provide value to your fantasy team.

Mitch Keller, RHP, Pittsburgh Pirates

Keller is another familiar name. Similar to Thaiss, he doesn't possess prospect status anymore, however, he seems worthy of mentioning here as he only has 120IP in his three seasons.

Many analysts thought that Keller might take the next step in his development this season, after having a good 2020. He even started the season in the Pittsburgh rotation. However early command issues and struggles limiting runs scored, Keller was eventually sent down to work on his development.

The Pirates elected to recall Keller this past weekend after spending the past two months at Triple-A. Keller did have mild success while at Triple-A, in eight appearances he had a 3.21ERA, with a 39:13 K:BB ratio.

Keller started for the Pirates last Sunday against the Phillies and did not fare well. His day ended with giving up four runs on eight hits in five innings. The lone bright spot being he limited the walks, but other than he was inefficient.

I would monitor Keller's progress and only add him in deeper leagues, otherwise, he can remain on the waiver wire until he can prove he's ready to take the next step forward.

Jo Adell, OF, Los Angeles Angels

This is the week of the Angels, as there is another top prospect being promoted. The time it's their number one prospect, outfielder Jo Adell. Not only is Adell the Angels' number one prospect he is also one of the top post-hype sleeper prospects remaining.

Adell did receive his first promotion back in 2020 but struggled mightily, as he only slashed 161/212/266, with three home runs, and zero stolen bases. He seemed overmatched at the plate as well as he struck out 42 percent of the time while only walking five percent of the time.

However, Adell has great power and speed abilities, which have been displayed in the minor leagues, as he has 58 HR in 297 games. He was also able to swipe 38 bags while only being caught seven times.

Adell didn't allow the Triple-A demotion to affect his production. He continued to put in work and the outcome was put on display, as he has slashed 289/342/592 with 23HR, 57R, 69RBI, and eight stolen bases through 73 games in 2021.

The Angels decided it was finally time to recall their 22-year-old outfielder yesterday and Matt Thaiss was sent back to Triple-A in a corresponding move. Adell was pushed right into the starting lineup in last night's game versus Texas.

I would add Adell in all leagues. Especially if you need power and outfield help. Adell has immense power and speed upside and should start contributing right away.


Tony Santillan, RHP, Cincinnati Reds

After making his big league debut earlier in 2021, Santillan has been sent packing back to Triple-A. He is the Reds ninth-ranked prospect and their fourth-ranked pitching prospect via MLB Pipeline,

Santillan debuted for the Reds back in June, as a starter. During his first four starts, Santillan saw success. He never gave up more than three runs in a start and struck out 20 batters. However the Reds elected to move him to the bullpen and he would then go onto make several appearances, with minimal success.

The Reds have also been playing musical chairs with him. He has been sent back and forth between the majors and Triple-A. Most recently, they sent him back to Triple-A this past weekend in order to make room for Michael Lorenzen, who is returning from the IL.

You can drop Tony in all leagues and formats.

Jared Oliva, OF, Pittsburgh Pirates

The 25-year-old outfielder is the Pirates' 16th ranked prospect via MLB Pipeline. The Pirates left-fielder debuted earlier this season in hopes of becoming more than a fourth outfielder.

Oliva did make his major league debut in 2020, similar to other prospects. Although it was in a very limited capacity, as he only appeared in six games and was only able to produce three hits.

Unfortunately, things have not gone much better for Oliva in 2021 either. So far in 20 appearances in 2021, he is only slashing .175/.233/225 and is striking out 23 percent of the time and only walking seven percent of the time. Jared was struggling so he was demoted to a bench role.

So the Pirates decided he would be better suited in the minors to receive the consistent at-bats. If you were rostering Oliva, I would drop him immediately as I am sure there are better outfield options on your waiver wire.
