Sebastian Rivero

Angels, Sebastian Rivero Agree To Minor League Deal

By | at

The Angels signed catcher Sebastián Rivero to a minor league contract last month, as reflected on the MLB.com transaction log. It’s unclear if he’ll be invited to major league Spring Training.

Rivero, 26, has two seasons of major league experience. He played in 34 games for the Royals between 2021-22, hitting .167 without a home run over 73 trips to the plate. Kansas City released him after the ’22 campaign. The Venezuelan-born catcher has spent the past two seasons in the upper minors, dividing his time between the White Sox and Braves organizations. He hit .186/.239/.249 in 75 games between Double-A and Triple-A in the Atlanta system a year ago. Rivero has been playing winter ball, where he’s hitting .182 in 21 games.

While there’s clearly not a ton of offensive upside, Rivero adds catching depth to the upper levels of the minors. He has started nearly 400 games and caught almost 3500 innings in his minor league career. Rivero has cut down around a quarter of attempted basestealers in each of the last two seasons.

Logan O’Hoppe and Travis d’Arnaud will divide the catching duties at Angel Stadium. Recent trade pickup Chuckie Robinson projects as the top depth option as the only other catcher on the 40-man roster. They hadn’t had any non-roster catchers with major league experience before signing Rivero, who could back Robinson up at Triple-A Salt Lake.

Braves Sign Ken Giles To Minor League Deal

By | at

The Braves announced their slate of non-roster invitees to spring training Friday, and while the majority of names within have already been reported or announced over the course of the offseason, there are a few notable names revealed within today’s release. Former Astros and Blue Jays closer Ken Giles, who recently worked out for teams, will be in camp after inking a minor league pact. Former Reds infielder Alejo Lopez and former Royals catcher Sebastian Rivero have also signed minor league contracts with non-roster invitations.

Now 33 years old, Giles was one of the game’s best relievers at his peak. He debuted with the 2014 Phillies and delivered consecutive sub-2.00 ERA seasons. From 2014-19, Giles racked up 114 saves between Philadelphia, Houston and Toronto while pitching to a 2.67 ERA and striking out one-third of his opponents against a 7.5% walk rate. Injuries have derailed that excellent start to his career; he underwent Tommy John surgery in 2020, which wiped out his 2021 season entirely.

Giles inked a two-year deal with the Mariners spanning the 2021-22 seasons, with Seattle hoping he’d be healthy for the second year of that arrangement. A strained tendon in his pitching hand pushed back his debut, however, and Giles only wound up pitching 4 1/3 innings with the M’s over the course of that two-year contract. Seattle declined a club option for the 2023 season. He pitched 20 innings in the Dodgers’ minor league ranks last year and fanned 32 hitters but also walked 19 while recording an 8.55 ERA.

Four full seasons have now been completed since Giles was last a dominant big league reliever. It’s perhaps a long shot for him to ever recapture that form, but there’s also little harm in the Braves taking what amounts to a no-risk look at him during spring training. Jon Heyman of the New York Post reports that the Rowley Sports Management client would earn at a $1.75MM rate if he’s added to the big league roster at any point.

Lopez, 27, has seen MLB time in each of the past three seasons with Cincinnati. He’s played second base, third base and all three outfield positions while posting a .265/.309/.329 batting line over the course of 181 plate appearances. The versatile Lopez has excellent bat-to-ball skills, evidenced by a 14.9% strikeout rate in the big leagues. In Triple-A, he’s walked at a 12.5% clip against a tiny 11.4% strikeout rate while batting .289/.384/.412 in 1030 plate appearances.

The 25-year-old Rivero appeared with the Royals in 2021-22, appearing in 34 games and batting .167/.236/.197 in 73 plate appearances. Rivero spent the 2023 season in the White Sox minor league system, splitting time between Double-A and Triple-A. He slashed .219/.273/.326 in that one-year stint with Chicago and is a career .247/.297/.369 hitter in parts of three Triple-A seasons. Rivero is touted as a plus defender behind the plate and sports strong framing marks in the minors in addition to a solid 27% caught-stealing rate across all levels in his professional career.

White Sox, Sebastian Rivero Agree To Minor League Deal

By | at

The White Sox are in agreement with catcher Sebastian Rivero on a minor league contract, tweets Lynn Worthy of the Kansas City Star. The 24-year-old backstop was released by the Royals last month.

Rivero, a Venezuela native, had spent his entire career in the Kansas City organization. Originally signed as an amateur free agent during the 2015-16 signing period, he played parts of six seasons in the minors. Rivero hasn’t hit much over that stretch, compiling a .247/.295/.357 line in a bit more than 1300 minor league plate appearances. He’s made contact at a roughly average rate but rarely walks and only has 20 professional home runs.

Despite the tepid offensive output, he played his way onto the 40-man roster over the 2020-21 offseason based on the strength of his defensive reputation. Kansas City kept him on hand as a depth option for the last two years, getting him into 34 combined contests. Rivero has managed only a .167/.236/.197 line in very sparse looks against big league pitching. He spent the bulk of the 2022 season at Triple-A Omaha, where he posted a .218/.294/.410 showing in 174 trips to the plate.

At the end of the season, Kansas City designated Rivero for assignment as part of a 40-man roster shuffle. They cut him loose, but he fairly quickly finds a new job. Chicago’s first-year skipper Pedro Grifol has spent the past decade in the K.C. organization, getting plenty of work with the team’s catchers in particular. That connection surely helped Rivero find this next opportunity.

The White Sox look likely to give Yasmani Grandal another shot to bounce back in the final season of his four-year contract. Carlos Pérez and Seby Zavala are on the 40-man roster as backup possibilities. Rivero looks likely to head to Triple-A Charlotte as a depth option behind that trio.

Royals Release Sebastian Rivero

By | at

The Royals announced Wednesday that they’ve requested unconditional release waivers on catcher Sebastian Rivero, whom they designated for assignment last week. He’d be a free agent upon clearing.

Being placed on release waivers surely isn’t how Rivero wanted to spend his 24th birthday, but that’s the position in which he finds himself. The Venezuelan-born backstop has appeared briefly in each of the past two big league seasons with the Royals but struggled to a .167/.236/.197 batting line in a tiny sample of 73 plate appearances. Rivero has had more success in Triple-A, albeit in a similarly small number of plate appearances. In 171 trips to the plate there, he’s slashed .266/.322/.380.

Rivero was optioned to the minors the maximum five times during the course of the 2022 season, plus another three times in 2021. The up-and-down nature of his time with the Royals over the past two seasons, coupled with the canceled 2020 minor league season, have played a role in limiting his overall experience in the upper minors. Despite debuting as a teenager back in 2016, Rivero has appeared in just 383 games as a professional. He sports an above-average 29% caught-stealing rate but has posted sub-par framing marks in the minors, per Baseball Prospectus. He’ll likely land with a team in need of some catching depth on a minor league deal this offseason.

Royals Select Richard Lovelady, Samad Taylor; Designate Sebastian Rivero

By | at

The Royals announced several roster moves, reinstating infielder Adalberto Mondesi, as well as lefties Jake Brentz and Angel Zerpa from the 60-day injured list. They also selected southpaw Richard Lovelady and infielder/outfielder Samad Taylor to the 40-man roster. Catcher Sebastian Rivero was designated for assignment.

Lovelady, 27, seemed to be having a nice breakout in 2021, posting a 3.48 ERA over 20 2/3 innings that year. Unfortunately, he required Tommy John surgery in September of that year and was non-tendered by Kansas City. The club re-signed him on a minor league deal, with Lovelady returning to the mound late in the year, making four appearances in the minor leagues in September. He would have qualified for minor league free agency today but the club has instead adding him back onto the 40-man roster.

Taylor, 24, was drafted by Cleveland but went to the Blue Jays as part of the Joe Smith trade. The Jays then flipped him to the Royals this summer as part of the Whit Merrifield deal. He got into 70 games for Triple-A Buffalo before the deal but didn’t play after it. In those 70 contests, he hit .258/.337/.426 for a wRC+ of 101 along with 23 steals. He’ll provide some versatility, spending most of 2022 at second base and left field, with a brief showing at shortstop as well. Like Lovelady, he would have qualified for minor league free agency if not selected to the roster today.

Rivero, 24 next week, has been on the 40-man roster for two years now, serving as an optionable depth catcher in that time. He got into 34 MLB games over the past two years but 84 games in the minors. Though he hasn’t hit much, this still creates a bit of a hole on the club’s depth chart. Salvador Perez and MJ Melendez are now the only two backstops on the roster. Since they are both likely to get regular playing time, either by the designated hitter spot or Melendez spending time in the outfield, the club will likely look to add a backup catcher at some point this offseason.

The moves for Mondesi, Brentz and Zerpa are formalities since the injured list ends today and doesn’t return until Spring Training. That means all players currently on the IL will need to be reinstated or else cut from the roster in some way.

Royals Select Michael Massey

By | at

1:00pm: The Royals announced to reporters, including Alec Lewis of The Athletic, that Zerpa has a small tear in the patellar tendon of his right knee.

11:42am: The Royals announced Wednesday that they’ve selected the contract of second baseman Michael Massey and recalled catcher Sebastian Rivero from Triple-A Omaha. Massey will take Whit Merrifield’s spot on the active roster, while Rivero is up in place of backup Cam Gallagher. Both Merrifield and Gallagher were traded prior to yesterday’s deadline. Lefty Angel Zerpa was moved to the 60-day injured list to open a spot on the 40-man roster for Massey.

Massey, the Royals’ fourth-round pick in 2019, is in enjoying an outstanding season in the minors, posting a combined .312/.371/.532 with 16 home runs, 28 doubles and 13 steals through 391 plate appearances. That includes a massive .325/.392/.595 batting line (158 wRC+) in 143 trips to the plate at the Triple-A level. Baseball America tabbed him eighth among Kansas City prospects on their midseason ranking of the system, giving him above-average grades for his hit tool, power and glove at second base.

With Merrifield traded, there’s a clear opening for the 24-year-old Massey to join Bobby Witt Jr. as a staple in the Kansas City infield. He’s certainly not as ballyhooed a prospect as Witt was prior to his debut, but Massey was selected with the 109th overall draft pick not long ago and has done nothing but hit since making his professional debut. For a 41-63 Royals club that is clearly playing for the future for the remainder of the current season, Massey is just the type of promising youngster who ought to command everyday at-bats in hopes of seizing a spot on next year’s roster.

As for the 23-year-old Rivero, he’ll give Kansas City a third catching option behind Salvador Perez and MJ Melendez. With that duo on the roster for the foreseeable future, it’ll be tough for Rivero to carve out much of a role, but he has a minor league option remaining beyond the current season. Rivero hasn’t hit in a tiny sample of 58 big league plate appearances, but he has a .266/.322/.380 line in 171 Triple-A plate appearances that’s at least passable for a catcher, particularly an organization’s No. 3 catcher on the 40-man roster.

Zerpa, 22, is one of the organization’s more promising pitching prospects, but a move to the 60-day injured list could very well mean the end of his season. The Royals placed him on the 15-day injured list due to a right knee injury last week but have yet to provide more details surrounding today’s shift to the 60-day IL.

IL Transactions: Matz, VerHagen, Lynch, De Jong

By | at

The Cardinals activated left-hander Steven Matz off the 15-day injured list today, as Matz was slated to start the Cardinals’ game against the Reds before the contest was rained out.  Matz will now have to wait until after the All-Star break to make his official return to the field, as he has been sidelined since May 22 due to a shoulder impingement.  With the Cards in need of rotation help, a healthy and effective Matz would be a major boost to the team, as both sides must hope that this two-month absence can essentially be a restart on Matz’s season.  After signing a four-year, $44MM free agent deal with St. Louis in November, Matz stumbled out of the gate with a 6.03 ERA over his first 37 1/3 innings in a Cardinals uniform.

To create room on the active roster, St. Louis placed right-hander Drew VerHagen on the 15-day IL with a right hip impingement.  A similar injury sent VerHagen to the injured list for a little over three weeks earlier this season, and the righty was just activated from another IL stint (due to shoulder problems) earlier this week.  With all of these health issues, it perhaps isn’t surprising that VerHagen has only a 6.65 ERA over 21 2/3 innings, with walks and home runs being particular issues for the 31-year-old.  VerHagen is another offseason signing for the Cards, joining the team on a two-year, $5.5MM deal after spending the previous two seasons pitching in Japan.

More comings and goings off the injured list from around the league…

  • The Royals placed left-hander Daniel Lynch on the 15-day IL, as Lynch is again dealing with a blister problem.  Lynch had already been sent to the IL with that same blister issue on June 24, and he was activated earlier this week and made two abbreviated starts before returning to the sidelines.  It has been a difficult season for Lynch, who has a 5.05 ERA and a wealth of troubling Statcast metrics over 15 starts and 71 1/3 innings.  Lynch’s IL placement was part of a busy day of roster moves for the Royals, who sent 10 players (Angel Zerpa, Nick Pratto, Gabe Speier, Collin Snider, Brewer Hicklen, Michael Massey, Freddy Fermin, Nate Eaton to Triple-A; Sebastian Rivero and Maikel Garcia to Double-A) to the minors in the aftermath of their series in Toronto.  This clears the way for the return of 10 Kansas City players, who were placed on the restricted list due to their non-vaccinated status.
  • The Pirates placed righty Chase De Jong on the 15-day IL due to tendinitis in his left knee, and Bryse Wilson (today’s starting pitcher against the Rockies) was called up from Triple-A in the corresponding move.  Another knee injury is perhaps a red flag for De Jong, who underwent surgery on that same left knee last year.  The surgery cut short De Jong’s first season in Pittsburgh, but after signing another minor league deal with the Bucs this past winter, De Jong has rebounded to post a 2.06 ERA over 35 relief innings in 2022.

Royals Add Nick Pratto, Seven Others To Major League Roster

By and | at

The Royals announced Thursday that they’ve recalled top first base prospect Nick Pratto from Triple-A Omaha as one of eight players joining the Major League roster. Also coming to the Majors are catcher Sebastian Rivero, infielder Maikel Garcia and lefty Angel Zerpa, who’ve been recalled from Double-A Arkansas. Additionally, the Royals selected the contracts of infielder/outfielder Nate Eaton, catcher Freddy Fermin, outfielder Brewer Hicklen and infielder Michael Massey from Omaha.

The deluge of additions comes in conjunction with the previously announced slate of ten current Royals heading to the restricted list in advance of the team’s road series against the Blue Jays, where travel restrictions prevent unvaccinated athletes from entering Canada. Andrew Benintendi, Dylan Coleman, Hunter Dozier, Cam Gallagher, Kyle Isbel, Brad Keller, MJ Melendez, Whit Merrifield, Brady Singer and Michael A. Taylor are all now formally on the restricted list.

As MLB.com’s Anne Rogers tweets, the roster spots of starting pitchers placed on the restricted list (i.e. Singer, Keller) cannot be filled until four days after they last pitched, per MLB rules, which explains the discrepancy between eight players being added versus the ten who went on the restricted list.

The Royals indicated in today’s announcement that they expect to add “up to two more players” to the big league roster over the course of the series. They’ll make another addition tomorrow and another on Sunday. Any players whose contracts were selected to the 40-man roster for this series can be returned to Triple-A without first needing to clear waivers, due to their status as Covid-19-related replacements.

Pratto’s promotion is the most notable of the bunch. The 14th overall pick in the 2017 draft, the California high school product slowly progressed up the minor league ladder. He had an awful 2019 showing in High-A, and the cancelation of the following minor league season dealt his prospect stock a hit heading into 2021. The lefty hitter rebounded in a huge way last year, blasting 36 home runs in a season split between the minors top two levels. That came with some alarming strikeout numbers, but Pratto’s combination of power and huge walk totals was enough to put him firmly in top prospect consideration. He entered the season as Baseball America’s #43 overall farmhand.

Assigned to Omaha to open this year, Pratto has essentially picked up where he left off. He’s hit 17 more longballs and drawn walks at a massive 15.1% clip, but he’s fanned in over 30% of his trips to the plate. The end result — a .240/.374/.484 line through 337 plate appearances — is still excellent. The Royals nevertheless brought up fellow top prospect Vinnie Pasquantino ahead of Pratto, seemingly preferring he get a long leash to iron out the strikeout concerns in the upper minors. It’s very possible he’ll head back to Omaha after the Jays’ series, but Kansas City fans will at least get their first glimpse at a player they hope eventually develops into a middle-of-the-order bat.

It’ll almost certainly be a brief stint for the group of players temporarily added to the 40-man roster. Hicklen was called up briefly as a COVID replacement earlier in the season. Fermin, Massey and Eaton all have opportunities to make their big league debuts in the coming days. Fermin, a former international signee out of Venezuela, is hitting .242/.357/.422 with Omaha this season.

Massey, a fourth-round pick out of Illinois in 2019, was recently named the #8 prospect in the Kansas City system by Baseball America. He owns a .348/.408/.630 line with six homers in 24 games since being bumped up to Omaha last month, and he’ll almost certainly land a permanent 40-man roster spot by next offseason (when Kansas City would need to add him to keep him from being selected in the Rule 5 draft). Eaton is a former 21st-round pick out of VMI. BA recently slotted him 29th in the farm system in recognition of his .329/.388/.591 showing with the Storm Chasers.

Injured List Transactions: Perez, Perdomo, McGee, Casali

By | at

The Royals reinstated catcher Salvador Perez from the 10-day injured list, and optioned catcher Sebastian Rivero to Triple-A in the corresponding move.  Perez missed only 11 days while recovering from a sprained left thumb suffered in the first game of a doubleheader on May 17, and the short turnaround time led the Royals to place Perez on the IL in between the two games.  Speaking with The Kansas City Star’s Lynn Worthy and other reporters, Perez said that he could be ready to resume catching duties tomorrow, as Perez will be in the DH role for today’s game with the Twins.

Following his huge 48-homer season in 2021, Perez has six homers and an underwhelming .206/.239/.397 slash line over 142 plate appearances to begin the 2022 campaign.  Perez has been making some hard contact but with little to show for it, and the longtime Royals backstop hasn’t been helping his cause with one of the lowest walk rates of any hitter in the league.

More on other players coming and going from the injured list…

  • The Brewers placed right-hander Luis Perdomo on the 15-day injured list with a right elbow effusion.  Righty Miguel Sanchez was recalled from Triple-A to take Perdomo’s spot on the active roster.  Milwaukee selected Perdomo’s contract earlier this month and he delivered a 1.74 ERA over 10 1/3 relief innings, but now faces another IL stint.  Since Perdomo missed the entire 2021 season recovering from Tommy John surgery, another elbow problem seems ominous, but Brewers manager Craig Counsell told the Milwaukee Journal Sentinel’s Todd Rosiak and other reporters that the injury doesn’t appear to be too serious.
  • The Giants reinstated left-hander Jake McGee from the 15-day injured list on Friday, though his actual return to the field was delayed by a clerical error.  McGee was called into yesterday’s game during the eighth inning, except he couldn’t pitch after the Reds told the umpiring crew that McGee wasn’t listed on the Giants’ official pregame lineup card.  As a result, Jose Alvarez was instead brought in to pitch, and Alvarez allowed two runs (one earned) to put the Giants into a deeper hole in an eventual 5-1 loss.  While not the wildest thing to happen to the Reds and Giants on Friday, it was the latest odd twist in what has been a rough season for McGee, who posted a 9.58 ERA in 10 1/3 innings out of San Francisco’s bullpen before back tightness sidelined him on May 11.
  • In another Giants move from today, the club reinstated catcher Curt Casali from the seven-day concussion IL and optioned Michael Papierski to Triple-A.  Casali was thankfully able to return in a minimal amount of time after taking a foul tip off his mask during a May 20 game.  This opened the door for Papierski to make his MLB debut, as the catcher appeared in five games while filling in for Casali.

Royals Release Glenn Sparkman

By | at

NOV. 23: The Royals announced that they have placed Sparkman on unconditional release waivers.

NOV. 20: The Royals have announced a series of roster moves (via Jeffrey Flanagan of MLB.com). Right-hander Glenn Sparkman and left-hander Gabe Speier have each been designated for assignment, while right-hander Chance Adams cleared waivers and was assigned outright to Triple-A Omaha. Those moves clear 40-man roster space for four players Kansas City added to protect them from the Rule 5 draft: outfielder Khalil Lee, catcher Sebastian Rivero, and left-handers Daniel Tillo and Angel Zerpa.

The 28-year-old Sparkman pitched in 31 games (23 starts) for Kansas City in 2019. He only managed a 6.02 ERA with a minuscule 13.4% strikeout rate in that time. The swingman started this season in the Royals’ bullpen but went down with a forearm strain after just five appearances.

Unlike Sparkman, Speier is exclusively a reliever. While he’s had some productive minor-league seasons, the 25-year-old hasn’t found much success at the game’s highest level. In seventeen MLB appearances for Kansas City over the past two seasons, Speier pitched to 7.62 ERA while walking an untenable 15.9% of opposing hitters.

Adams underwent Tommy John surgery last month and won’t pitch next season. The former well-regarded Yankee farmhand will try to work his way back into the mix in 2022.
