Connor Kaiser

Lourdes Gurriel Jr. Diagnosed With Torn ACL

By Darragh McDonald | September 2, 2025 at 11:50pm CDT

The Diamondbacks announced today that right-hander Taylor Rashi and infielder Connor Kaiser have been recalled from Triple-A Reno. In corresponding moves, they have optioned Juan Burgos to Reno and placed outfielder Lourdes Gurriel Jr. on the 10-day injured list with a torn right ACL.

It was apparent that Gurriel was injured last night. He and center fielder Blaze Alexander were both chasing a ball in the gap. Gurriel hopped to avoid his teammate but then collapsed on the ground in obvious pain. He eventually had to be carted off, unable to properly put weight on his leg.

Today’s diagnosis is obviously awful for both Gurriel and the Snakes. They haven’t announced an expected timeline but a torn ACL can often require something close to a year of recovery before the player is back to full strength. Gurriel will certainly miss the remainder of this season and a notable chunk of 2026 as well.

Gurriel was initially acquired ahead of the 2023 season alongside Gabriel Moreno, as part of the trade which sent Daulton Varsho to the Blue Jays. Gurriel was an impending free agent at the time but re-signed after one good season in Arizona. He returned via a three-year, $42MM pact with a club option for 2027 and an opt-out chance for him after 2025.

Triggering the opt-out wasn’t especially likely. He is only hitting .248/.295/.418 this year, with that line translating to a 94 wRC+. However, he does have 19 home runs and it’s possible the overall lack of production is due to a .254 batting average on balls in play. That’s well below this year’s .291 league average and Gurriel’s personal career rate of .305.

His decision would have effectively come down to whether he felt he could beat one year and $18MM. His current contract pays him $13MM next year, with a $5MM buyout on the $14MM club option for 2027. Perhaps a hot finish could have made him think about walking away from that money but it’s a moot point now. Since he’s going to miss some amount of next year, he’ll surely forgo his opt-out chance.

For the Diamondbacks, this adds to their 2026 body count well before the season has even begun. Corbin Burnes required Tommy John surgery in June and will therefore miss most or perhaps all of the upcoming campaign. Tommy Henry, Blake Walston, A.J. Puk and Justin Martínez also underwent UCL surgeries this year and are facing lengthy absences. Now Gurriel adds another name to the list.

Those other names are all pitchers while Gurriel subtracts a key part of the club’s outfield mix. Without him, the 2026 outfield consists of guys Corbin Carroll, Alek Thomas, Jake McCarthy, Jorge Barrosa and Alexander. Carroll is a star but it’s a questionable group after that. Thomas is in his fourth season and has good defensive grades but he hasn’t hit. McCarthy has shown occasional flashes of competency at the plate but his good seasons may have been fuelled by BABIP luck and he’s been awful this year. Alexander is having a nice run right now but he strikes out a lot and has only recently moved from the infield to the outfield. Barrosa has just 58 big league plate appearances and hasn’t impressed yet.

Going into the winter, the Diamondbacks have a lot to do. Given their injuries, deadline trades and impending free agents, they need to remake almost their entire pitching staff. They have question marks at the infield corners after trading Josh Naylor and Eugenio Suárez at the deadline. Those spots could be filled by guys like Jordan Lawlar and Tyler Locklear but neither is a lock yet. Gurriel could have been a solid regular on next year’s team but now there’s one more thing on the to-do list.

Diamondbacks Select Kyle Nelson, Connor Kaiser

By Steve Adams and Anthony Franco | August 1, 2025 at 8:48pm CDT

The Diamondbacks announced Friday that they’ve selected the contracts of lefty Kyle Nelson and shortstop Connor Kaiser from Triple-A Reno. Arizona also reinstated veteran reliever Jalen Beeks from the injured list. First baseman Tyler Locklear, acquired in the Eugenio Suárez trade, was added to the major league roster. Lefty Brandyn Garcia (acquired in the Josh Naylor deal) and infielder Tristin English were optioned to Reno.

Nelson, 29, was a key member of Arizona’s bullpen in 2022, tossing 37 innings with a 2.19 ERA in his first year after coming over from Cleveland. His numbers dipped in 2023-24, however, and Nelson was removed from the 40-man roster in early July by way of a DFA. He passed through waivers unclaimed. In 22 2/3 innings for Reno this year, he’s been roughed up for a 6.35 ERA thanks to a whopping seven home runs allowed. Most of those struggles came earlier in the year, however. He’s rattled off 6 1/3 shutout innings over his past eight appearances.

Kaiser, 28, provides a glove-first infielder off the bench. He’ll work in a utility capacity as Blaze Alexander, who had been the depth infielder, will get everyday third base run with Suárez out the door. A Vanderbilt product, Kaiser is hitless in four career major league plate appearances. Those came over three games with the Rockies two seasons ago. He’s batting .236/.346/.423 in a hitter-friendly Triple-A setting this year.

Diamondbacks Sign Aramis Garcia To Minor League Deal

By Anthony Franco | November 16, 2024 at 10:21am CDT

The D-Backs signed catcher Aramis Garcia and shortstop Connor Kaiser to minor league contracts. Both players will get invites to big league camp. The deals were announced by Arizona’s Triple-A club in Reno.

Garcia, 32 in January, has more big league experience of that duo. The righty-hitting catcher has appeared in parts of five MLB seasons, logging 119 games between four teams. That included three games and seven hitless at-bats with the Phillies this year. Garcia isn’t much of an offensive threat. He’s a career .211/.248/.325 hitter with a 35.8% strikeout rate across 327 plate appearances. He had an even poorer showing in the minors this past season, hitting .159/.216/.279 while punching out nearly 36% of the time in 76 Triple-A games.

Teams are always on the hunt for catching depth, so the Snakes will send Garcia to Reno to begin next season. Statcast hasn’t graded him favorably for his blocking skills but credits him with a plus arm. Garcia did a nice job controlling the run game in Triple-A this year. He cut down more than 32% of attempted basestealers over 584 innings behind the plate.

Kaiser, who turns 28 next week, is a glove-first infielder. A former third-round pick of the Pirates, he got into three big league games with the Rockies in 2023. That’s the extent of his MLB work. Colorado outrighted Kaiser off their 40-man roster midway through that season. He spent this year with the Rox’s top farm team in Albuquerque. Despite playing in an extreme hitter’s park, the Vanderbilt product put up a .221/.343/.339 line through 347 plate appearances. Kaiser took his share of walks but stuck out at a near-32% clip. He’s also likely to begin next season in Reno, potentially in a utility capacity.

Rockies Outright Connor Kaiser

By Steve Adams | July 5, 2023 at 9:18am CDT

Rockies infielder Connor Kaiser went unclaimed on outright waivers following this weekend’s DFA, tweets Thomas Harding of MLB.com. He’s been assigned to Triple-A Albuquerque and will remain with the organization while no longer occupying a spot on the 40-man roster.

Kaiser, 26, was added to the roster for his big league debut a few days ago when Ezequiel Tovar was placed on the paternity list. He appeared in three games during Tovar’s absence but went hitless in four trips to the plate during that span. Colorado designated Kaiser for assignment when Tovar returned from paternity and when a 40-man roster spot was needed to select the contract of veteran reliever Fernando Abad.

A third-round pick by the Pirates back in 2018, Kaiser has since bounced to the Padres and Rockies organizations in minor league free agency. He joined the Rox over the winter and turned in a solid .263/.357/.485 batting line with eight homers, 13 doubles, three triples and seven steals in 224 plate appearances at the Triple-A level while seeing time at shortstop and third base.

The Rox now have Tovar back in the fold and Ryan McMahon slotted in at the hot corner. Elehuris Montero is also an option at third or first, while Alan Trejo and Harold Castro can play around the diamond. Coco Montes gives the Rox another infield option on the 40-man roster down in Triple-A. Kaiser will remain on hand as a depth option, perhaps getting another call and another chance at logging his first big league hit if the Rockies incur an injury among that group of infield options.

Rockies Select Fernando Abad

By Nick Deeds | July 2, 2023 at 12:17pm CDT

The Rockies announced today that they’ve selected the contract of left-hander Fernando Abad. In corresponding moves, right-hander Peter Lambert was optioned to Triple-A while shortstop Connor Kaiser was designated for assignment.

Abad, 37, made his MLB debut with the Astros back in 2010. The veteran journeyman pitched also pitched for the Nationals, A’s, Twins, Red Sox, Giants, and Orioles throughout his career before landing in Colorado on a minor league deal back in January. Abad was selected to the roster back in May and made three appearances with the Rockies before being designated for assignment and re-signing with the club on a new minor league deal shortly thereafter.

The veteran sports a career 3.82 ERA and 4.31 FIP in 351 innings of work, though most of that success came from 2010-17. Since the end of the 2017 season, Abad has recorded just 33 1/3 innings of work at the big league level with a 5.40 ERA and 5.09 FIP. The lefty has posted impressive numbers with Colorado’s Triple-A affiliate in Albuquerque, however, with a sterling 1.40 ERA in 25 2/3 innings of work. Those run prevention numbers are especially impressive considering the heightened offensive environment in Triple-A’s Pacific Coast League.

Going forward, Abad will look to re-establish himself at the big league level with the Rockies as part of a bullpen that currently contains Daniel Bard, Brad Hand, Justin Lawrence, and Pierce Johnson as late-inning options. Abad joins Hand and Ty Blach as left-handed options in the bullpen for manager Bud Black.

Making room for Abad on the 40-man roster is shortstop Connor Kaiser, who appeared in just three games with the Rockies when selected to the roster back in June while Ezequiel Tovar was on the paternity list. A third round pick by the Pirates in the 2018 draft, Kaiser posted a roughly league average slash line of .263/.357/.485 in 224 plate appearances at the Triple-A level with the Rockies this season. Still just 26 years old, Kaiser seems likely to be placed on waivers, where any club will have the opportunity to claim him. Should he go unclaimed, the Rockies will have the option to assign Kaiser outright to the minors where he would continue to serve as infield depth for the club.

Clearing space on the active roster, on the other hand, is Lambert. The 26-year-old righty was a second round pick by the Brewers in the 2015 drat and once seemed like a promising prospect, but injuries and ineffectiveness have dogged him in recent years. In 2023, Lambert has posted a 6.29 ERA and a 5.99 FIP in 34 1/3 innings of work at the big league level. As noted by MLB.com’s Thomas Harding, Lambert is expected to pitch out of the rotation in Triple-A, providing the club with additional starting depth going forward.

Rockies Select Connor Kaiser

By Darragh McDonald | June 19, 2023 at 3:00pm CDT

The Rockies announced that they have selected the contract of infielder Connor Kaiser. He will take the active roster spot of infielder Ezequiel Tovar, who has been placed on the paternity list. The club already had a vacancy on their 40-man roster.

Kaiser, 26, was a third-round selection of the Pirates in the 2018 draft. He rose through the ranks with that club but topped out at Triple-A and was released in 2022. He then signed a minor league deal with the Padres but qualified for minor league free agency at the end of last season.

The Rockies scooped him up on a minor league deal this winter and he’s been playing for their Triple-A club this year. He’s made 205 trips to the plate in 50 games, walking in 13.2% of those. His .278/.376/.506 batting line amounts to a wRC+ of 108, indicating he’s been 8% above league average. He’s also stolen six bases on the year while playing primarily at shortstop but also a bit at third base. He hasn’t played second base this year but has in the past.

He will provide the Rockies with a versatile bench piece, at least as long as Tovar is gone. Stints on the paternity list can be between one and three days, meaning it’s possible this will be a cup of coffee for Kaiser, who has a full slate of options.
