The Orioles activated Eflin (back) from the 15-day injured list Wednesday.

Eflin will rejoin the Orioles rotation Wednesday with a start against the Guardians after being sidelined nearly a month due to lower-back discomfort. The veteran right-hander threw 68 pitches over four innings in his final rehab outing in the rookie-level Florida Complex League last Friday, so Eflin will be somewhat limited from a workload perspective Wednesday.

Gusto has made his last three appearances for the Astros as a reliever, covering 6.1 innings in total while allowing two earned runs on six hits and two walks while striking out five.

Gusto has made 12 starts for Houston this season and had been a fixture in the rotation since late May, but the Astros transitioned him to the bullpen shortly before the All-Star break. In Houston's final series of the first half, Gusto came on in long relief July 11 following a short start by Lance McCullers, and he made a pair of one-inning appearances in last weekend's series in Seattle. McCullers has since been placed on the injured list due to a blister on his right hand, so Gusto could be needed once again to plug one of the holes in the rotation. Houston is listing Hunter Brown and Colton Gordon as its starters for the final two games of its upcoming four-game series with the Athletics, but Gusto could be called upon to start or work in bulk relief Thursday or Friday.

Rosario (elbow) had not had surgery yet as of April, per Evan Grant of The Dallas Morning News.

There are plenty of rumors circulating online that Rosario still hasn't had the procedure, which was recommended in February. Even if Rosario had the procedure in July, he could potentially miss the entire 2026 season. Rosario was trending toward being a top-five pitching prospect at the time of his injury, so he's still worth stashing in most dynasty leagues, but it's a mystery as to when we'll see him healthy and pitching in games again.

The Twins placed Festa on the 15-day injured list Wednesday due to right shoulder inflammation.

Festa struggled in his most recent start Monday against the Dodgers, allowing three home runs and four runs over 5.1 innings. It's not clear, however, whether his shoulder was bothering him during the outing. The right-hander will be eligible for activation Aug. 6, but the Twins won't have a clear idea regarding when he might return until he starts throwing again.

Urquidy (elbow) threw a 30-pitch live batting practice session Tuesday at the Tigers' spring facility in Lakeland, Fla., Evan Petzold of the Detroit Free Press reports.

Urquidy faced hitters for the first time since undergoing Tommy John surgery in June 2024. The right-hander will need to face hitters on several more occasions before the Tigers send him out on what will most likely be an extended minor-league rehab assignment. Urquidy is unlikely to return from the 60-day injured list until around mid-to-late August.

The Tigers selected Melton's contract from Triple-A Toledo ahead of his scheduled start Wednesday versus the Pirates at PNC Park.

Detroit placed ace Tarik Skubal (personal) on the paternity list to open up a spot on the 26-man active roster for Melton, who will be making his MLB debut Wednesday. As a result of Melton's addition, the Tigers will be running out a six-man rotation this week, but expect the team to scale back to five men once Skubal returns from the paternity list to start Saturday versus Toronto. Whether Melton sticks around for additional starts will likely hinge on how he performs Wednesday, as well as how incumbent No. 5 starter Keider Montero fares in his upcoming outing Friday versus the Blue Jays. The 25-year-old Melton has been unfazed by minor-league competition during his stops at Toledo and Double-A Erie this season, accruing a 2.99 ERA, 1.23 WHIP and 101:20 K:BB in 75.1 innings between the two affiliates.

Fitts (1-4) took the loss Tuesday as the Red Sox fell 4-1 to the Phillies, surrendering four runs on six hits over 3.1 innings. He struck out four without walking a batter.

Solo homers by Max Kepler and Kyle Schwarber in the second inning put the game out of reach for Boston, as Cristopher Sanchez was busy tossing a 12-K complete game for Philly. Fitts has served up seven long balls in 17 innings over his five big-league appearances and 17 innings since the beginning of June, fueling a 7.41 ERA, but with Tanner Houck (elbow) shut back down indefinitely and Hunter Dobbins (knee) lost for the season, there's no obvious internal replacement for Fitts in the Red Sox's rotation. He's scheduled to make his next start on the road early next week in Minnesota.

Mize (9-4) took the loss Tuesday as the Tigers were downed 8-5 by the Pirates, coughing up five runs (four earned) on 10 hits and a walk over four innings. He struck out five.

The right-hander tossed 62 of his 86 pitches for strikes and managed to keep the ball in the yard, but Mize still allowed far too much loud contact as six of the 10 hits off him wound up turning into doubles. He's been tagged for 11 runs (10 earned) over his last two starts, but Mize still sports a 3.40 ERA, 1.28 WHIP and 82:23 K:BB through 92.2 inning on the year. He'll look to turn things around in his next outing, which is scheduled to come at home early next week against the Diamondbacks.

Rasmussen allowed two runs on three hits and a walk while striking out five in four innings Tuesday against the White Sox. He did not factor into the decision.

Rasmussen went nine up and nine down to open the game but ran into some trouble in the fourth. He allowed a double, two singles and a walk before a sacrifice fly plated a second run in the inning for the White Sox. Rasmussen exited after tossing 75 pitches, his most in an outing since he threw 92 on June 19. The team reported before the All-Star break that Rasmussen was expected to handle a typical starter's workload when making his next turn through the rotation, but it seems manager Kevin Cash is still being somewhat cautious with Rasmussen's pitch count. The right-hander lines up to toe the rubber again next week on the road versus the Yankees.

Detroit placed Skubal on the paternity list Wednesday, but he's expected to be activated in time to make his next start Saturday versus the Blue Jays at Comerica Park, Evan Petzold of the Detroit Free Press reports.

Skubal will likely spend the maximum three days away from the team while he and his wife welcome their second child before he returns to action Saturday to start on five days' rest. By temporarily deactivating Skubal, the Tigers were able to open up a spot on the 26-man active roster for right-hander Troy Melton, who was called up from Triple-A Toledo to start Wednesday in Pittsburgh in what will be his MLB debut.
