Rays vs. Rockies Prediction, Winner Payout, Over/Under – Tuesday, August 4

It’s long overdue that we stop calling the Rays a surprise story and just call them what they are — the best team in the American League this year. Tampa Bay is 66-46 on the year and owns a 3.5-game lead over the New York Yankees for the best record in the AL and the division lead in the AL East.

Tampa Bay added reinforcements during the trade deadline, bringing in Peralta from the New York Mets while also adding C Liam Hicks to their lineup from the Miami Marlins. They'll need these pieces to pay off, as the Yankees added talent of their own at the deadline and will only get better as offensive weapons come off the IL.

The Colorado Rockies continue to try to bring back baseball vibes to 20th and Blake in downtown Denver. Colorado sits at 45-68 this season and, for the first time in a long time, doesn't own the worst record in baseball.

This is a team that has already surpassed last year's win total of 43 games, and this group of young players seems to have finally turned the corner for the Rockies.

Colorado is built around a new youth movement of OF Cole Carrigg, C Hunter Goodman, and 1B TJ Rumfield. As these young players gain more major league experience, this could certainly be a team that fights for a Wild Card spot in the coming years.

• Rockies SP Gabriel Hughes has been mighty impressive in his debut season. He owns a 3.33 ERA, but both his xERA (2.34) and xFIP (2.36) sit in the elite range.
• Rays SP Freddy “Fastball” Peralta runs into an extremely difficult matchup in Colorado against a Rockies team that can hit the fastball with the best of them.

Rays vs. Rockies Picks, Player Stats for PrizePicks: 8/4/26

Here are the top Rays vs. Rockies picks to target on Tuesday, August 4. Today’s MLB picks for PrizePicks include Freddy Peralta and TJ Rumfield.

Rays P Freddy Peralta vs. Rockies: 5 Strikeouts

• Peralta is in the midst of his worst strikeout season as a big leaguer, with his 8.95 K/9 ranking as by far his worst K/9.
• Even though he's on a new ball club, it's still worth noting that he has had major road struggles this season with a 6.31 ERA and 5.26 FIP away from home compared to a 4.10 ERA and 3.91 FIP at home.
• Peralta is throwing his fastball 53.4% of the time, and the Rockies own the fourth-best wFA/C (fastball runs above average per 100 pitches) in baseball (0.27).
• Colorado also owns the third-best wFB (23.5) as a team, meaning it's scored 23.5 runs above average against the heater.

Rockies 1B TJ Rumfield vs. Rays: 1.5 Hits + Runs + RBI

• Rumfield alone owns a 10.2 wFB; it's the pitch he's had by far the most success against in his young career.
• Peralta’s worst split has been on the road against LHB, where he is giving up a 49.5% fly ball rate and a 37.9% hard-hit rate — two stats that could lead to disaster in a hitter's haven like Coors Field.
• Rumfield’s best split has been at home against RHP, where he owns a .338 average and a monster 152 wRC+.
• The young infielder has surpassed this projection in five straight home games he's started.
