Rays Sign John Rooney To Minor League Deal

By | at

The Rays announced they’ve signed lefty reliever John Rooney and infielder Raynel Delgado to minor league contracts with invitations to big league Spring Training. Francys Romero first reported the Delgado signing last night.

Rooney elected minor league free agency after being outrighted by the Astros at the beginning of the offseason. The 28-year-old had a brief stint with Houston, who acquired him from the Marlins in a small trade in August. (Rooney could be traded after July 31 because he’d been on a minor league contract.) The Astros called him up for his big league debut three weeks later. Rooney struck out two of six batters faced while giving up a solo home run to Luis Vázquez in his only appearance.

The Astros placed him on the injured list after that game. Rooney underwent season-ending surgery to treat tennis elbow and remove bone spurs. He’ll try to work his way back to the big leagues with Tampa Bay next spring. Rooney sits just 90-91 MPH with his fastballs while leaning more often on a low-80s breaking ball. It missed a lot of bats in Triple-A, where he struck out 34% of opponents en route to a 2.56 ERA in 43 appearances between Miami’s and Houston’s affiliates. He held left-handed hitters to a .155/.282/.169 line with 37 strikeouts and nine walks in 85 Triple-A plate appearances this year.

Delgado, 26 in April, has not played in MLB. He’s a former sixth-round pick by Cleveland who spent last season with the Brewers top farm team. The left-handed hitter put together a solid .281/.363/.378 slash while stealing 40 bases in 48 attempts. Delgado is stretched at shortstop but can serve as a depth piece at either second or third base.

Astros Put Five Players On Outright Waivers

By | at

The Astros have put five players on outright waivers, reports Chandler Rome of The Athletic. They are outfielders Chas McCormick, Kenedy Corona and Pedro León, left-hander John Rooney and right-hander Luis Garcia. Michael Schwab of The Ice Box reported on McCormick earlier today.

Some roster maintenance was inevitable for the Astros. They had a large number of injuries in 2025, leading to several players ending up on the 60-day injured list. The IL goes away five days after the World Series and doesn’t return until spring training, so the club would need to open some spots.

Garcia, 29 in December, was an easy cut. 2026 was slated to be his final arbitration season before he qualified for free agency. He underwent Tommy John surgery last month and is going to miss that entire campaign. The Astros weren’t going to tender him a contract, so he’s been bumped off the roster now.

For the same reasons, he should pass through waivers unclaimed, unless some club wants to work out a two-year deal covering his recovery and theoretical return to the mound in 2027. But it’s more likely that clubs wait for him to clear and become a free agent before discussing such deals with him.

McCormick, 31 in April, is the other guy in this batch with notable major league experience. He was a solid contributor for the Astros from 2021 to 2023. He struck out a lot but hit at least 14 home runs in each of those campaigns. He slashed a combined .259/.336/.449 for a 120 wRC+ in that span with 27 stolen bases and strong defensive grades, with contributions in the postseason as well.

Unfortunately, he’s been nowhere near that productive in the past two years. He has slashed .211/.273/.301 since the start of 2024, production that translates to a 64 wRC+. MLBTR contributor Matt Swartz projected him for a $3.4MM arbitration salary next year. After two years of struggles, the Astros were probably going to non-tender him.

He is controllable through the 2027 season, so perhaps he gets claimed by some club who views him as a change-of-scenery candidate. However, it’s also possible that clubs wait for him to clear and then reach free agency, at which point they could try to sign him at a lower price point than the projected salary.

León, 28 in May, was once a high-profile signing out of Cuba but he hasn’t yet been able to deliver on the hype. He has only played in seven big league games so far. His minor league numbers have been more decent than amazing. A sprained MCL in his left knee put him on the shelf for most of 2025, limiting him to just 25 games.

It’s possible León garners interest from other clubs based on his past prospect pedigree. He still has options and could be stashed in the minors next year. While his 2025 was mostly a lost year, he slashed .299/.372/.514 in Triple-A last year for a 130 wRC+.

Corona, 26 in March, was an international signing of the Mets. He came to the Astros in the December 2019 trade which sent Jake Marisnick to Queens. Houston put Corona on their 40-man roster in November 2023, to keep him out of the Rule 5 draft.

His numbers have backed up since then. He has only played in three big league games. He has a .217/.311/.309 batting line and 74 wRC+ in the minors dating back to the start of 2024. That was a big drop from his 2022 and 2023 production, as he slashed .264/.346/.475 for a 116 wRC+ over those seasons. Like León, he still has options, which could increase the chances some other club grabs him as a depth option.

Rooney, 29 in January, was just acquired from the Marlins in an August cash deal. He has one big league appearance under his belt, having allowed one earned run over 1 1/3 innings for the Astros on August 24th. He tossed 38 2/3 Triple-A innings this year with a 2.56 earned run average, 34.2% strikeout rate, 14.9% walk rate and 42.5% ground ball rate. The lefty underwent surgery late in the year remove bone spurs and address tennis elbow. Per Rome, he’s expected to miss the entire 2026 season.

Garcia and McCormick each have enough service time to reject outright assignments and elect free agency if they clear waivers. Rooney and Corona have been in the minors for at least seven years, meaning they would be eligible for minor league free agency five days after the World Series, if they are off the roster by then. León doesn’t have seven years in the minors, nor does he have three years of service or a previous career outright. If he clears waivers, the Astros should be able to keep him as non-roster depth.

Astros’ Brandon Walter Undergoes UCL Surgery

By | at

Astros southpaw Brandon Walter underwent UCL reconstruction surgery yesterday, the team informed reporters (including Chandler Rome of The Athletic). Meanwhile, Ari Alexander reports that southpaw John Rooney had a procedure to remove bone spurs and address tennis elbow.

Houston had announced a couple weeks back that both pitchers were going under the knife. They didn’t provide specifics at the time beyond calling each a season-ending elbow procedure. The news is obviously much worse for Walter, who’ll miss all of next season. Rooney’s surgery is less significant and it doesn’t seem out of the question that he’ll be available for Spring Training.

Walter, 29, had proven a nice pickup on a minor league deal last August. Houston selected his contract at the end of May. Walter picked up nine starts for an injury-riddled rotation. He tossed a quality start in six of those outings, working to a 3.35 earned run average across 53 2/3 innings overall. The former Red Sox prospect punched out a quarter of batters faced against a pristine 1.9% walk rate. Walter overcame pedestrian velocity to get chases and whiffs at slightly above-average rates.

Unfortunately, the injury bug struck again for the 29-year-old. Walter missed the entire 2024 season after suffering a rotator cuff injury while pitching in minor league camp with Boston. That led the Red Sox to release him, paving the way for him to land in Houston. Walter probably showed enough for the Astros to keep him on the 40-man roster throughout the upcoming offseason. They’d be able to place him back on the 60-day injured list at the beginning of Spring Training.

Rooney may have a tougher time sticking on the roster. He was on a minor league deal with the Marlins when Houston acquired him at the beginning of August. Rooney came up for his big league debut in late August. He tossed 1 1/3 innings of one-run ball before suffering the season-ending injury. The 28-year-old reliever combined for a 2.56 ERA over 38 2/3 Triple-A frames this year.

Astros’ Brandon Walter, John Rooney To Undergo Elbow Surgery

By | at

Astros left-handers Brandon Walter and John Rooney will undergo season-ending elbow surgery this week, the team announced. Houston did not specify the sort of procedure either pitcher will require. Walter landed on the injured list due to elbow inflammation back in late July. Rooney also hit the IL due to inflammation, though his original placement was just a couple weeks ago.

In an additional bit of ominous news, the Astros announced that right-hander Spencer Arrighetti is slated to receive a second opinion on his elbow this week. Arrighetti, like Walter and Rooney, was originally placed on the IL due to inflammation in his elbow. (It’s common for elbow injuries to be originally diagnosed as inflammation and for a more specific diagnosis to become apparent once the swelling/inflammation dies down and a better look at the joint’s structural integrity is available.) A second opinion will conjure up fears of a worst-case scenario, though Houston has not yet suggested that surgery is on the table.

Walter’s injury is particularly deflating. The left-hander missed all of the 2024 season due to a strained rotator cuff in his left shoulder. He wound up being cut loose by the Red Sox, signing with the Astros on a minor league deal, and emerging as a key member of the 2025 staff.

In nine starts, the 29-year-old Walter pitched 53 2/3 innings and logged a 3.35 ERA, 24.5% strikeout rate and immaculate 1.9% walk rate. That breakout performance, even if truncated by this elbow injury, proved pivotal at a time when the Astros were reeling from injuries to Ronel Blanco, Hayden Wesneski and Arrighetti (who, at that point, was still on the mend from a fractured thumb rather than his current elbow concern).

Rooney, 28, made his big league debut with Houston last month. He tossed 1 1/3 innings, allowed a run, and seemingly suffered an elbow injury in the middle of that debut effort. It’s unfortunate for any player to incur an injury, though if there’s a silver lining it’s that Rooney will pick up major league service time and pay for the final four-plus weeks of the season, dating back to his Aug. 24 promotion. Had he not sustained the injury, he might’ve been optioned back to Triple-A Sugar Land at any point.

That’s probably not much consolation to Rooney, a former Dodgers third-rounder who grinded through the better part of eight professional seasons before finally getting to the majors with his third organization. He’s split the 2025 season between the Triple-A affiliates for the Marlins and Astros, pitching to a combined 2.56 ERA with a huge 34.2% strikeout rate but a clunky 14.9% walk rate.

As for Arrighetti, it’s a most unwelcome development for a pitcher who hasn’t seemed to catch any luck this year. The 25-year-old’s previously referenced fractured thumb occurred when he was playing catch in the outfield during batting practice early in the season and was struck by a line drive from a teammate. He returned from that injury in early August and made five starts, struggling through the first three before appearing to turn a corner in the fourth. In his final two starts before going back to the IL, he logged 12 innings and held opponents to three runs on seven hits and five walks with 10 strikeouts.

Manager Joe Espada had already conceded that Arrighetti’s injury might cost him the remainder of the season. Word of a second opinion from an external source only serves to increase that likelihood.

In the meantime, the Astros will turn to righty J.P. France to help deepen the staff. Chandler Rome of The Athletic reports that France is with the club in Toronto and is expected to pitch out of the bullpen. The 30-year-old France had shoulder surgery last summer and missed much of the current season rehabbing. He’s been pitching as a multi-inning reliever in Triple-A recently, though his last outing was a start: five innings of one-run ball against the Dodgers’ top affiliate.

France has an unsightly 6.59 ERA in 27 1/3 innings of Triple-A work overall this season, but he’s pitched better of late, including a pair of five-inning appearances with one combined run in his past four trips to the mound. He’ll give Espada some length at a time when Houston has eight pitchers on the big league injured list.

Astros Place Spencer Arrighetti On Injured List

By | at

The Astros placed Spencer Arrighetti on the 15-day injured list shortly before tonight’s game against the Yankees. The placement, which is retroactive to August 31, is due to inflammation in his throwing elbow. Houston selected reliever Jayden Murray onto the MLB roster in his place. Lefty John Rooney has been moved from the 15-day to the 60-day injured list to create a 40-man roster spot. The Astros also activated Victor Caratini from the concussion list and optioned Chas McCormick to Triple-A Sugar Land this afternoon.

Arrighetti tossed 6 1/3 innings of one-run ball against the Angels on Saturday. He apparently came out of that appearance with elbow soreness. The Astros waited until just before game time tonight to put him on the shelf. Injured list placements can be backdated for up to three days. The Astros determined Arrighetti will need at least another 12 days before he’s ready to pitch.

Houston activated Luis Garcia from the injured list on Monday. They intended to go to a six-man rotation, ideally affording an extra day of rest for Garcia and Cristian Javier with both pitchers just back from elbow surgery. This will force a change of plans. They can drop back to a five-man starting staff with Javier and Garcia following Hunter Brown, Framber Valdez and Jason Alexander. If they want to keep a six-man rotation, they could reverse course on the plan to move Lance McCullers Jr. to the bullpen. Colton Gordon is in the Triple-A rotation, while rookie AJ Blubaugh could build back to rotation work after beginning his MLB career in the bullpen.

Arrighetti has spent most of the season on the IL after breaking his thumb on a fluke injury when he was hit by a ball during batting practice in April. The second-year righty has been limited to seven starts and carries a 5.35 ERA across 35 1/3 innings. He took the ball 29 times a year ago, pitching to a 4.53 mark over 145 frames in his rookie season.

Murray gets his first major league opportunity at age 28. The 6’1″ righty has thrown 64 innings of 4.64 ERA ball over 50 appearances with Sugar Land. Murray has fanned 24% of opponents while issuing walks to nearly 11% of batters faced. He has pitched well of late, allowing only six earned runs in 23 innings going back to the beginning of July. A former Tampa Bay draftee, Murray was traded to the Astros while he was pitching in Double-A as part of the three-team Trey Mancini/Jose Siri deal in 2022.

Rooney, also 28, was acquired from Miami last month. He made his MLB debut on August 24 against Baltimore, giving up one run while recording four outs. Houston placed him on the injured list with elbow inflammation after that appearance, and he’s now out for the season. The Astros will need to reinstate him onto the 40-man roster or put him on waivers at the beginning of the offseason.

On the position player side, Caratini returns to split time behind the dish with Yainer Diaz. The Astros will keep third catcher César Salazar on the active roster as well. That means the first minor league stint of the season for McCormick, who is batting .210/.279/.290 across 116 plate appearances. McCormick was a valuable and underrated outfield piece over his first three seasons, but he’s amidst his second straight very poor year. He’s a long shot to make Houston’s playoff roster (if they qualify) and will be a non-tender candidate this winter.

Astros Promote John Rooney

By | at

The Astros optioned right-hander AJ Blubaugh to Triple-A prior to today’s game against the Orioles, and called up left-hander John Rooney to provide the bullpen with a fresh arm.  Rooney was already on Houston’s 40-man roster, so the Blubaugh demotion was the only corresponding move necessary.

Rooney is on the mound at the time of this post, and thus the 28-year-old is now officially a Major League player.  A third-round pick for the Dodgers back in the 2018 draft, Rooney spent his whole pro career in the Los Angeles farm system until 2025, when he joined the Marlins as a minor league free agent.

Miami then dealt Rooney to Houston earlier this month, and he has a 2.56 ERA and a 34.2% strikeout rate over 38 2/3 combined innings with the Marlins’ and Astros’ Triple-A affiliates.  Those impressive numbers came with the downside of a 14.9% walk rate.  Rooney has been prone to issuing free passes for most of his career, and a move to full-time bullpen work in 2023 only briefly solved his control issues.

It remains to be seen if Rooney will get anything more than a cup of coffee in the Show, as the Astros have Steven Okert and Bryan King as the primary left-handers in their bullpen.  However, the relief corps lost a pair of very prominent southpaws (Josh Hader and Bennett Sousa) to the injured list, and starter Colton Gordon is the only other Triple-A lefty on the 40-man roster.  This could open the door for Rooney to get more of an extended look on the active roster if he can produce against MLB hitters.

Astros Acquire John Rooney From Marlins

By | at

The Astros have acquired left-hander John Rooney in a trade with the Marlins, as relayed by Chandler Rome of The Athletic. The Marlins are receiving cash considerations in return. Rome adds that Rooney will join the team today, and that right-hander Luis Contreras was optioned to Triple-A in order to make room for Rooney on the active roster. Houston has a 40-man roster vacancy, so no further corresponding transactions will be necessary.

Rooney, 28, was eligible to be traded even after the deadline on July 31 passed because he has spent the entire year in the minor leagues without being selected to the 40-man roster. MLBTR’s Steve Adams offered a comprehensive look at how clubs can make external additions over the season’s final two months yesterday morning. A third-round pick by the Dodgers back in 2018 who has yet to make his MLB debut, Rooney is a veteran of seven minor league seasons who will now get the opportunity to break into the majors for the first time in his career.

Prior to this season, Rooney had spent his entire career in the Dodgers organization. He reached Triple-A in the latter half of the 2023 season but struggled with the club’s Oklahoma City affiliate in his first full season at the level in 2024 despite some early success there the year prior. Rooney went on to elect minor league free agency and latched on with the Marlins, for whom he’s done quite well at Triple-A Jacksonville this season. In 38 appearances, Rooney has posted a 2.45 ERA while striking out 32.4% of his opponents. Those impressive strikeout numbers are held back by a massive 16.5% walk rate, however, and Rooney’s command will surely need to improve if he hopes to be more than a depth option at the big league level.

Despite that lackluster control, the Astros are clearly enticed by Rooney’s big strikeout numbers if they offered him a spot on their 40-man roster and a shot in the majors. The competition among left-handed relief arms in the Houston bullpen is extremely stiff, however. Closer Josh Hader and second-year setup man Bryan King are both locked into high leverage spots, while Bennett Sousa and Steven Okert are both having excellent seasons in their own right. All four of those southpaws figure to land well ahead of Rooney on the organizational depth chart, but additional relief depth with options remaining is always a worthwhile addition for a contender to consider.

For now, Rooney will take the spot of Contreras on the active roster. Contreras is in his second year in the majors with the Astros, but he’s done little to impress so far with a 7.50 career ERA. With that being said, those poor results have come in just 18 innings of work total, and his 4.12 FIP suggests that there are better days to come. Contreras will head to Triple-A Sugar Land, where he has a 3.34 ERA in 30 appearances this year, and wait for his next opportunity in the majors.
