MLB Mailbag: Jordan Walker, Cubs, Guardians, Tigers, Riley
This week's mailbag gets into Jordan Walker's hot start, the Cubs' approach to Cade Horton's season-ending injury, the future of the Guardians, and slow starts for the Tigers as well as Braves third baseman Austin Riley.
Sam asks:
I know it way too early to ask this question I cannot help it. Jordan Walker has a 183 wRC+ and is on pace for 39 HRs is he has 456 ABs (ZIPS AB projection). He will cool off a bit—at least. But say he has finally arrived (met his potential, however you want to call it) and settles into being a 130-135 wRC+ and 30-35 HR hitter, how do you think that impacts the Cardinals' short and long term outlook with their rebuild?
Walker, 24 in May, sits at a 181 wRC+ through 44 plate appearances after hitting a solo home run in five trips to the plate Tuesday at Nationals Park.
I pulled up the wRC+ leaderboard last year through April 6th, with a minimum of 40 plate appearances. Here's a list of the top 20, first showing their wRC+ through April 6th and then showing what it was for that player for the rest of the season.
- Aaron Judge - 246 / 202
- Kyle Tucker - 224 / 126
- Kristian Campbell - 207 / 63
- Tyler Soderstrom - 206 / 119
- Jackson Merrill - 201 / 108
- Spencer Torkelson - 193 / 112
- Anthony Volpe - 192 / 75
- Corbin Carroll - 181 / 136
- Nolan Arenado - 178 / 75
- Kyle Schwarber - 178 / 151
- Lars Nootbaar - 171 / 90
- Alex Bregman - 166 / 121
- Fernando Tatis Jr. - 164 / 129
- Sal Frelick - 162 / 110
- Heliot Ramos - 159 / 103
- Brendan Donovan - 157 / 115
- Jose Altuve - 155 / 111
- Teoscar Hernandez - 153 / 97
- Eugenio Suarez - 152 / 123
- Jazz Chisholm Jr. - 150 / 124
- Jordan Westburg - 149 / 110
- Shohei Ohtani - 148 / 174
- Andres Gimenez - 147 / 60
- Julio Rodriguez - 144 / 125
- Nico Hoerner - 138 / 108
- Jackson Chourio - 136 / 109
- Seiya Suzuki - 135 / 121
- Lawrence Butler - 134 / 93
- Rafael Devers - 134 / 135
- Brice Turang - 134 / 123
Walker came into the 2026 season with 1,039 Major League plate appearances and an 89 wRC+. Every player is different, but the best comp here might be Torkelson, even though the latter had a little more experience and success in his career to that point. But I'd say the range of rest-of-season outcomes on Walker remains very wide: this could be nothing, or a full breakout. Sorry, the truth is often boring.
I also think it's worth asking whether Walker has hit like this in the Majors before. For that, we use the Stathead Span Finder. I'm not a huge OPS guy, but that's probably the best "overall offense" stat in this tool. Walker's OPS is currently 1.014, spanning 11 games and 44 PA. He has had a couple of streaks at least this good, basically in June and August of his 2023 rookie season:
- 6-6-23 to 6-18-23: Walker hit .395/.477/.789 (1.267 OPS) with 4 HR in 44 PA
- 8-22-23 to 9-5-23: Walker hit .432/.488/.838 (1.326 OPS) in 4 HR in 43 PA
Even in his lousy 2025 season, Walker had a 43-PA July run where he hit .342/.419/.500 (.919 OPS) over 43 PA, though he did not homer during that streak.
What kind of evidence is on the breakout side of the ledger?

Pirates Outright Enmanuel Valdez
The Pirates sent utility infielder Enmanuel Valdez outright to Triple-A Indianapolis, per the MLB.com transaction log. He evidently cleared waivers after being designated for assignment when the Bucs called up Konnor Griffin last week.
Pittsburgh acquired Valdez from Boston over the 2024-25 offseason in a DFA trade that sent minor league pitcher Joe Vogatsky to the Sox. He spent a month as Pittsburgh’s primary first baseman while Spencer Horwitz was working back from wrist surgery. Valdez hit .209/.294/.363 across 31 games before sustaining a season-ending dislocation of his left shoulder, which required surgery.
Valdez is healthy but no longer had much of a path to playing time on the Pittsburgh infield. Horwitz has established himself as the primary first baseman. They acquired Brandon Lowe to play second and have Griffin up at shortstop. Third base is still a question mark, especially with Jared Triolo shelved by a knee injury, but Valdez had dropped below Nick Yorke and Nick Gonzales on the infield depth chart.
The 27-year-old Valdez owns a .230/.288/.392 batting line in a little less than 500 MLB plate appearances. He didn’t hit during Spring Training and is out to an 0-10 start with five punchouts through four Triple-A games. He doesn’t have the service time or previous career outright to elect free agency. Valdez will remain at Indianapolis, where he’d begun the season on optional assignment, and try to shake off the rust offensively. He’d qualify for minor league free agency at the end of the season if the Bucs don’t add him back to the 40-man roster.
Diamondbacks Re-Sign Joe Ross To Minor League Deal
The Diamondbacks re-signed righty Joe Ross to a minor league contract. He has been assigned to Triple-A Reno, where he’s back in action.
Ross had a brief stay on the open market after electing free agency earlier in the week. Arizona had designated him for assignment. It’s common for veterans in his position to decline an outright assignment but re-sign on a new minor league deal. Those can come with a higher minor league salary or opt-out/upward mobility opportunities that might not have been present had they accepted the outright.
The 32-year-old Ross broke camp in a long relief role after signing a minor league contract in February. He worked a perfect inning in his season debut but was knocked around over the next two appearances. Ross gave up six runs without getting through an inning against the Tigers on March 30. He surrendered three walks and a Mauricio Dubón homer in a blowout loss to Atlanta two days later.
Ross has plenty of starting experience but has worked as a multi-inning reliever for the past year-plus. He posted a 5.12 ERA across 51 innings out of the Philadelphia bullpen last season. Ross worked in relief of pitching prospect Mitch Bratt tonight in his first appearance with Reno. He gave up six hits and four runs, including a two-run homer to Trey Mancini, across 2 1/3 frames.
Gabriel Arias To Miss 4-8 Weeks With Moderate Hamstring Strain
The Guardians will be without shortstop Gabriel Arias for 4-8 weeks, the team announced. The infielder suffered a moderate strain of his left hamstring while legging out a double during Monday’s loss to the Royals.
Arias started 10 of Cleveland’s first 11 games at shortstop. He connected on a couple home runs but otherwise hasn’t contributed at the plate, batting .200 with 12 strikeouts in 32 plate appearances. That’s usual for Arias, who strikes out as much as any regular in MLB. He’s in the lineup for his above-average glove.
Brayan Rocchio slides over from second base to replace Arias as the regular shortstop. Rocchio has ample shortstop experience and should be a steady if unspectacular hand there. The bigger change comes at second base, where the Guardians called up prospect Juan Brito when placing Arias on the injured list yesterday.
The switch-hitting Brito has hit well throughout his minor league career and is out to a 4-8 start with a couple doubles as a big leaguer. There’ll be a defensive downgrade in the middle infield, though, as scouts have long been cool on Brito’s glove. He committed an error on a routine grounder in this afternoon’s win over Kansas City. Skipper Stephen Vogt could lean on Daniel Schneemann as a defensive upgrade late in games. Schneemann also projects as the backup shortstop if Rocchio needs a day off.
Arias will be sidelined into May and may be down into June. There’s a chance that top second base prospect Travis Bazzana, the first overall pick in 2024, is up by that point. Bazzana is out to a relatively slow start in Triple-A, though playing in cold weather in April is probably a factor. Aside from Chase DeLauter, Cleveland hasn’t hit much in the early going. They’re nevertheless out to an 8-5 start with series wins over the Dodgers, Cubs, and Kansas City behind excellent work from the starting rotation.
Zach Eflin Undergoes UCL Surgery
The Orioles announced that Zach Eflin underwent UCL reconstruction (Tommy John) surgery today. He’ll miss the rest of the season and probably at least the first half of 2027.
Things had seemingly been trending in this direction. Eflin, who turns 32 today, left his season debut citing elbow discomfort. The team announced last week that he was going for a second opinion, implying the initial prognosis wasn’t good. The reexamination evidently confirmed the ligament damage that required surgical repair.
It’s another injury-wrecked season for Eflin, a mid-rotation caliber starter who has an unfortunately checkered health history. He battled chronic knee issues early in his career with Philadelphia. Eflin stayed mostly healthy between 2023-24 despite intermittent back discomfort, combining for a 3.54 ERA with a 23.1% strikeout rate over 343 innings between the Rays and Orioles.
The more significant injuries have resurfaced over the past two seasons. Eflin sustained a lat strain early in 2025. That shelved him for a month. He quickly returned to the injured list with lower back discomfort. After a brief reinstatement, he underwent season-ending lumbar surgery. Eflin made an encouraging return from that procedure and entered this season with no restrictions, but he could only complete 3 2/3 frames before his elbow gave out.
Baltimore re-signed Eflin to a one-year, $10MM free agent contract last offseason. That’ll go down as an unfortunately lost investment. Eflin, whom the O’s have already moved to the 60-day injured list, will return to the open market at season’s end. He’ll likely look for a two-year deal to cover his rehab season. That might need to be a minor league contract given his age and recent durability record.
Trevor Rogers, Kyle Bradish, Shane Baz and Chris Bassitt remain Baltimore’s top four starters. They recalled lefty Cade Povich as a potential fifth starter on Sunday. He was needed in relief of Bassitt, who was shelled and only made it through two innings against the Pirates. Povich tossed 5 2/3 innings of two-run ball in relief. Brandon Young made a spot start on Monday and was optioned back to Triple-A postgame.
The O’s are off tomorrow and list Baz, Bassitt and Povich as the probable starters for their weekend series against the Giants. Rogers and Bradish, who started the final two games of this week’s series against the White Sox, would line up early next week against the Diamondbacks. It seems they’ll give Povich first look as Eflin’s replacement in the rotation. Young and Dean Kremer are on optional assignment with Triple-A Norfolk.
Davey Lopes Passes Away
The Dodgers announced today that Davey Lopes passed away today at the age of 80. Lopes made his debut as a player in the early 1970s and went on to have a career as a coach and manager, making him a staple of the game for the bulk of five decades.
Lopes was a late bloomer. He didn’t make it to the majors until 1972, which was his age-27 season. Even then, he only got into 11 games for the Dodgers. The following year, his age-28 campaign, he finally established himself as a big league regular. He became the club’s second baseman and showed off the speed that would become his standout trait. He swiped 36 bags that year, his first of what would eventually be a 14-year streak of stealing at least 15 bases.
He stayed on the Dodger roster through the 1981 season, mostly covering the keystone but also with occasional action at shortstop, third base and in the outfield. The Dodgers had a very consistent infield during that stretch, with Steve Garvey the mainstay at first, Lopes at second, Bill Russell at short and Ron Cey at third.
Lopes played in 1,207 games for the Dodgers from his 1972 debut until the end of that 1981 campaign. He hit .262 in that time and launched 99 home runs but the eye-popping stat was his 418 stolen bases. He led the league in steals in both 1975 and 1976, with 77 in the former and 63 in the latter. The second instance was particularly impressive as injuries limited him to only 117 games. In 1978, he won a Gold Glove and also made the All-Star team, the first of four straight All-Star selections.
The Dodgers were quite good in that time but couldn’t quit win a title for most of it. They lost the World Series to the Athletics in 1974, then to the Yankees in both 1977 and 1978. In 1981, they were able to get the job done, topping the Yankees 4-2. Lopes stole ten bases in in 16 postseason games that year.
Prior to the 1982 season, he was traded to the A’s, kicking off the journeyman phase of his career. He would also bounce to the Cubs and Astros, playing past his 42nd birthday. He finished his career with 7,340 plate appearances over 1,812 games. He racked up 1,671 hits, including 155 home runs. He scored 1,023 runs and drove in 614. His 557 steals put him 26th on the all-time list.
He quickly pivoted to his post-playing career by becoming a bench coach with the Rangers. That was followed by stints as a first base coach with the Orioles and Padres. He was hired to manage the Brewers for the 2000 season. The club did not fare well and he was fired early in 2002. He never got another managerial gig and had a 144-195 record in that job. He then went back to being a first base coach, starting with a return to the Padres, followed by stints with the Nationals, Phillies, Dodgers and back to the Nationals. He retired from coaching after the 2017 season.
We at MLB Trade Rumors join the rest of the baseball world in sending condolences to the Lopes family as well as everyone else mourning him today.

Cristian Javier Exits Start Due To Shoulder Tightness
Astros right-hander Cristian Javier was removed from today’s game after just one inning due to shoulder tightness. As relayed by Chandler Rome of The Athletic, Javier was warming up for the second inning but summoned catcher Christian Vázquez and the training staff to the mound before departing.
At this point, it’s too early to know any details about Javier’s injury or its severity. However, even a minor absence would be a big blow for the Astros. Just a few days ago, they lost their ace, as Hunter Brown landed on the injured list due to a shoulder strain.
Even with Brown’s injury, the Astros still planned to go for a six-man rotation in the near future. On Friday, they start a stretch of playing 13 games in a row. Going to a six-man rotation would lower the impact on Tatsuya Imai, who is still in the first few weeks of his MLB career. In Japan, starting pitchers normally throw once a week as opposed to the five-man rotations that are common in North America.
Imai, Javier, Burrows and Lance McCullers Jr. would have accounted for four spots. The other two would have been more up in the air. Cody Bolton was just recalled to make a spot start and could be in the mix. Spencer Arrighetti is on optional assignment but could be recalled. Ryan Weiss, AJ Blubaugh, and Kai-Wei Teng have some starting experience but have been pitching in the big league bullpen. Blubaugh came in to replace Javier today but allowed five runs in the second and was replaced in the third. He threw 39 pitches in his one inning of work.
Subtracting Javier would further require the Astros to reach even further into their depth, assuming they still want to go six deep in the rotation. Weiss threw 62 pitches in a long relief outing Monday, so he’s fairly stretched out, though he allowed six earned runs in 2 2/3 innings. Houston also has Jason Alexander, Colton Gordon and Miguel Ullola on optional assignment.
Houston’s outfield also seemingly took a blow today. Jake Meyers tried to check his swing during a plate appearance and grabbed at his oblique area. He left the game and the Astros announced his injury as lower back tightness. Meyers has taken the majority of playing time in center field this year. He is a strong defender and has a solid .243/.326/.378 line so far on the season.
If Meyers needs to miss some time, then the Astros will have to figure out a solution in center. Brice Matthews entered the game for Meyers today. He is one of the club’s best prospects but he entered today with just 22 games of big league experience and a .148/.212/.410 line in those. Right fielder Cam Smith has gotten some work in center but not in official game action. Left fielder Joey Loperfido does have some center field experience but less than in the corners.
Houston has Zach Cole and Shay Whitcomb on optional assignment. However, Cole recently broke his toe when he was hit by a pitch in a Triple-A game. His timeline is unclear but he’s not immediately available. Whitcomb has far more infield experience than he does on the grass. In terms of non-roster options with outfield experience, they have Taylor Trammell, Cavan Biggio and CJ Alexander.

Jorge Soler, Reynaldo López Given Multi-Game Suspensions
3:50pm: Chad Bishop of the Atlanta Journal-Constitution reports that MLB and López reach a settlement whereby his suspension is reduced to five games and he will start serving it immediately. It’s not clear if that includes today’s game, which started a few minutes after the suspension announcement.
Grant Holmes started for Atlanta today and the club is off tomorrow. On Friday, they start a series against the Guardians with Bryce Elder, Martín Pérez and Chris Sale scheduled to start. After that, they being a series against the Marlins. López’s turn in the rotation would have been the first game of that Miami series. Atlanta could instead go for Holmes on normal rest or turn to swingman José Suarez. They have Didier Fuentes and Víctor Mederos on optional assignment and could recall one of those two for a spot start.
3:00pm: Major League Baseball has announced that Angels outfielder Jorge Soler and Braves right-hander Reynaldo López have each been suspended for seven games and given undisclosed fines in relation to last night’s brawl. Both players are appealing and can continue to play until the appeals process has been completed.
López started last night’s contest for Atlanta. In the first inning, Soler launched a two-run home run off him. In the bottom of the third, Lopez hit Soler with a pitch. Soler came up again in the fifth and López threw a pitch up and in. The pitch didn’t hit Soler but he clearly took exception to it and stared López down for an extended period of time. The two exchanged words before Soler charged the mound and the two threw punches towards each other, as seen in this video from BravesVision. Both were ejected after that melee.
Players given suspensions for on-field infractions cannot be replaced on the roster. That means that the two clubs will have to play short-handed at some point. That will be on pause for now while the players are appealing.

Angels Injury Notes: Trout, Yates, Rodriguez
Outfielder Mike Trout was back in the lineup on Tuesday against the Mariners. The future Hall of Famer was sidelined on Monday with a hand injury. Trout was hit by a 94 mph fastball from Casey Legumina in the eighth inning of Sunday’s game against the Mariners. He was immediately removed from the contest.
Trout singled and scored in his return to the lineup. He was on base for Jorge Soler‘s two-run blast in the first inning. Those wouldn’t be the last fireworks from Soler that evening. Trout’s base hit had an exit velocity above 100 mph, so he would seem to be back to full strength.
The 34-year-old Trout’s production has cooled considerably after a huge opening series. The veteran slugged home runs in the first two games of the campaign. Trout racked up six hits and seven walks in the four-game set against the Astros. He’s recorded just a pair of hits since then.
We’re still working with tiny sample sizes at this point of the season, and the main development for the Angels is that Trout is healthy and available to contribute in the middle of the lineup. He played 130 games last year, his most since 2019. Trout is now back in his familiar spot in center field after spending most of 2025 at DH.
On the pitching side, right-hander Kirby Yates faced hitters on Tuesday, per Jeff Fletcher of the Orange County Register. The reliever is working his way back from knee inflammation. The 39-year-old was positioned to open the year as the Angels’ closer while Ben Joyce and Robert Stephenson dealt with their own injuries, but Yates hit the IL himself shortly before Opening Day.
The Angels will see how Yates recovers from yesterday’s work and determine the next step in his rehab process, relays Fletcher. He could be headed on a minor league assignment soon. The Angels signed Yates to a one-year, $5MM pact in January. The reliever was the club’s largest spend of the offseason. Los Angeles also added veteran bullpen arms Jordan Romano and Drew Pomeranz to improve a unit that ranked 28th in ERA last season. Romano has taken over as closer, securing four saves across six scoreless innings.
The Angels’ biggest swing of the offseason was sending outfielder Taylor Ward to the Orioles for right-hander Grayson Rodriguez. After four MLB Spring Training appearances with his new club, Rodriguez went down with shoulder inflammation. The former top prospect missed all of 2025 with a lat strain. Injuries have limited him to 43 starts since his big-league debut in 2023. Rodriguez is feeling better and is nearing mound work, per Fletcher.
