Alfonso Rivas

27-Year-Old First Baseman1B
St. Louis Cardinals
2024 Fantasy Outlook
Rivas spent the majority of his 2023 season with Triple-A El Paso, though he was shipped to Pittsburgh at the trade deadline and got fairly regular run at first base for the final two months of the campaign. Across 106 plate appearances in that span, he hit .234/.305/.436 while striking out 27.3 percent of the time. Since the close of the season, he's been claimed by both the Guardians and Angels off waivers and could have the chance to earn a backup first base or DH role in Los Angeles behind Nolan Schanuel. Even with regular playing time, Rivas's skill profile isn't particularly inspiring, though it is worth noting that he raised his launch angle to 11.1 degrees and his flyball rate to 41 percent in 2023. If he can keep those improvements and find his way to some playing time, he could be a corner infield option in the deepest of leagues. Those hopes aren't worth the use of a draft pick.

The Cardinals outrighted Rivas to Triple-A Memphis on Thursday after he cleared waivers.
ANALYSIS
While no longer on St. Louis' 40-man roster, Rivas will remain in the organization as depth. The 27-year-old is sporting just a .246/.364/.323 batting line with zero home runs this season at Memphis.

Latest Fantasy Rumors
MLB chance on horizon?
1BSan Diego Padres  AAA
May 25, 2023
Rivas could be added to San Diego's big-league roster this weekend if Manny Machado isn't cleared to return from his hand injury, per AJ Cassavell of MLB.com.
ANALYSIS
Machado isn't expected to be activated from the injured list when first eligible Friday, and Ha-Seong Kim also suffered a knee injury Thursday. The Padres are in need of infield depth, and Rivas could fit the bill given his .309/.425/.583 slash line with Triple-A El Paso this season.

Past Fantasy Outlooks
2023
2021
2020
Rivas saw his first extended run in the majors in 2022, and he didn't fully capitalize on the opportunity. After appearing in 18 games in 2021, the infielder upped that to 101 games, and he slashed .235/.322/.307 across 251 at-bats. Rivas had a notable drop in batting average, falling from .318 to .235, and his OPS dropped from .797 to .629. The 26-year-old functioned as a platoon player, as he only saw 32 plate appearances against left-handed pitchers. The left-handed Rivas has historically struggled against southpaws, so the limited exposure made sense and is unlikely to change moving forward. The Cubs opted to move on from Rivas in December, and he joined the Padres on a minor-league deal a couple weeks later. He should serve as organizational depth for San Diego and is unlikely to crack the Opening Day roster.
Rivas moved from Oakland to Chicago in a January 2020 trade for Tony Kemp. Though he wasn't selected to train at the Cubs' alternate site, Rivas was part of the team's Arizona instructional league roster, and he reportedly performed well in that opportunity. The 24-year-old has a pretty left-handed swing that he has used to compile a .290 average across two minor-league seasons and is not shy about taking a walk, registering a 13.0 BB% over 800 plate appearances during that span. Rivas' hit tool could translate to big-league success, but his ability to stick in an everyday role could come down to his growth as a power hitter. Rivas has hit only 10 homers over 183 minor-league games, so he'll need to add some pop to earn everyday at-bats. His hitting profile has been compared to that of Mark Grace, which sounds great until you recall that Grace averaged only 11 homers over 16 big-league campaigns.
At 6-foot, 188 pounds, Rivas lacks typical size for first base and will be heading to Double-A for his age-23 season, but he has been a high-level performer thus far. The reason he fell to the A's in the fourth round of the 2018 draft was that many evaluators questioned whether he could hit for enough power to profile at first base. That question remains, and the answer will determine whether or not he matters in fantasy. His plate skills (13.0 BB%) and all-fields approach bode well for his ability to have relative success at Double-A and Triple-A. He hit .260/.355/.327 against lefties, so he could be platooned in the majors. Rivas slashed .311/.429/.467 in the Arizona Fall League, but his 28.6 K% was easily his worst mark in pro ball. He has some experience in left field, so he would debut there if he remains with Oakland, as he is obviously not displacing Matt Olson.
