Alberto Rodriguez

Mariners Outright Alberto Rodriguez

By Anthony Franco | January 24, 2023 at 11:19pm CDT

The Mariners announced that minor league outfielder Alberto Rodriguez has gone unclaimed on waivers. He’ll stick in the organization at High-A Everett on outright assignment.

Rodriguez entered the professional ranks as an amateur signee of the Blue Jays in 2017. He was dealt to Seattle three years later as part of the trade that sent Taijuan Walker to Toronto. The left-handed hitter drew some attention from prospect evaluators for his power upside and was regarded as a possible future right fielder. The M’s put him on their 40-man roster last winter to keep him out of the Rule 5 draft.

He spent his entire age-21 campaign in High-A on optional assignment. Rodriguez hit .261/.336/.396 with 10 home runs across 527 plate appearances. That’s decent production but not overwhelming for a bat-first prospect. More concerning, he went down on strikes in more than 26% of his trips. That dealt enough of a hit to Rodriguez’s long-term value that Seattle took him off the 40-man to claim J.B. Bukauskas last week.

The M’s took the risk of losing Rodriguez, but no other team was willing to devote him a 40-man spot either. He’ll remain in the system as an upside flier for the Seattle player development staff, where the M’s can monitor the progress of his bat-to-ball skills as he tries to work his way to the big leagues.

Mariners Claim J.B. Bukauskas, Designate Alberto Rodriguez

By Darragh McDonald | January 17, 2023 at 3:45pm CDT

The Mariners announced that they have claimed right-hander J.B. Bukauskas off waivers from the Diamondbacks. In a corresponding move, outfielder Alberto Rodriguez has been designated for assignment. Bukauskas was designated for assignment last week when the D-Backs re-signed Zach Davies.

Bukauskas, 26, was a first round draft pick of the Astros in 2017 and he landed on top prospect lists shortly thereafter. However, many evaluators predicted his inability to consistently throw strikes would lead to a bullpen move down the line. Those predictions proved to be fairly astute as Bukauskas moved up the minor league ladder and struggled with walks. In 85 2/3 innings for Houston’s Double-A affiliate in 2019, he walked 14.2% of batters faced and posted a 5.25 ERA.

The Diamondbacks acquired Bukauskas alongside three other players when they traded Zack Greinke to Houston and have since had him spend most of his time as a reliever. His control has certainly improved in that time but injuries have limited him to a small workload. In 2021, he only pitched 30 innings between the majors and the minors due to a strain in his throwing elbow. Last year, a Grade 2 strain in the teres major muscle in his shoulder put him on the injured list from the start of the year until July. The D-Backs kept him on the farm once he was healthy, but he fared well there. He posted a 2.42 ERA in 22 1/3 innings while striking out 25.3% of batters faced and walking just 4.6% of them. Most of that work came in the Pacific Coast League as well, which has a reputation for being quite hitter-friendly.

The M’s have decided to take a shot on Bukauskas to see if they can be the ones to benefit from a breakout. The righty still has an option year remaining, allowing them to keep him in the minors until he’s needed with the big league club. He also has just over a year of service time and can be kept around for the foreseeable future as long as he holds a spot on the 40-man.

In order to take a chance on Bukauskas, the M’s are risking losing the 22-year-old Rodriguez. An amateur signing of the Blue Jays, he was traded to the Mariners as part of the 2020 deal that sent Taijuan Walker to the Jays. In 2021, he hit .289/.379/.470 between Single-A and High-A, a strong enough showing to get him added to the 40-man roster ahead of the Rule 5 draft. Last year, he went back to High-A and still hit fairly well. His .261/.336/.396 showing was good enough for a 106 wRC+, or 6% above league average. However, he struck out in 26.2% of his plate appearances and only stole six bases after going well into double digits in previous seasons.

The Mariners will now have a week to trade Rodriguez or pass him through waivers. Though his 2022 season wasn’t ideal, he’s still a young and talented outfielder who has a couple of option years remaining. As recently as midway through 2022, Baseball America still considered him one of the club’s top 30 prospects.

Mariners Select Julio Rodriguez, Two Others

By Steve Adams | November 18, 2021 at 12:08pm CDT

The Mariners announced Thursday that they’ve selected the contract of top outfield prospect Julio Rodriguez, thus adding him to the 40-man roster and protecting him from the 2021 Rule 5 Draft. Also added to the 40-man roster were fellow outfielder Alberto Rodriguez and lefty Ray Kerr. Seattle’s 40-man roster is now up to a total of 39 players.

Rodriguez was about the most obvious 40-man addition any team would make in advance of tomorrow afternoon’s deadline to protect players from the Rule 5 Draft. The 20-year-old is heralded as a potential superstar, ranking as the sport’s No. 2 overall prospect at Baseball America and MLB.com and landing No. 6 over at FanGraphs.

Despite his youth, Rodriguez is expected to make his big league debut at some point in 2022 — if not on Opening Day then perhaps early in the year. (The looming collective bargaining talks could impact the timing.) Rodriguez, 21 in late December, split the 2021 season between Class-A Advanced and Double-A, turning in a dominant .347/.441/.560 against much older and more experienced pitching (particularly in Double-A). The Mariners are expected to be aggressive in free agency and in trades this winter as they look to launch themselves back into the postseason, but president of baseball operations has already stated there’s “no scenario” where Rodriguez or the other very best prospects in his system are traded (link via The Athletic’s Corey Brock).

As for Alberto Rodriguez, the Mariners picked up from the Blue Jays in the 2020 trade that sent Taijuan Walker to Toronto. About nine months older than Julio, Alberto split the 2021 season between Class-A and Class-A Advanced, hitting at a .289/.379/.470 clip with 10 home runs, 31 doubles, five triples and 15 steals. The 21-year-old’s best skill is his considerable raw power, per scouting reports at BA, MLB.com and FanGraphs, though there are concerns about his hit tool and defense in the outfield corners. The elder Rodriguez generally ranks in the No. 20-25 range on Mariners prospects lists, although Seattle has arguably the best farm system in baseball, so he’d place higher with most other teams.

Kerr, 27, joined the Mariners as an undrafted free agent in 2017 and has steadily risen through the system. After working as a starter early in his pro career, the 6’3″ lefty moved to the bullpen in 2021 and notched a combined 3.18 ERA with a huge 36.8% strikeout rate, a slightly high but manageable 9.8% walk rate, and a strong 53% ground-ball rate. A hard-throwing southpaw who can touch the upper 90s, miss bats and keep the ball on the ground at that rate in Double-A/Triple-A would surely have piqued the interest of other clubs. The Mariners’ selection of Kerr immediately thrusts him into the mix for a bullpen spot next season — particularly given the lack of proven southpaws in the relief mix at present.
