Eovaldi has been scratched from his scheduled start Sunday versus Detroit due to tightness in his back, Kennedi Landry of MLB.com reports.

Sunday was slated to be a marquee pitching matchup between Eovaldi and the Tigers' Tarik Skubal, but that duel won't happen. Instead, the Rangers have tabbed Jacob Latz to start opposite Detroit's ace. Eovaldi had an IL stint in June due to a triceps injury, and he has made four starts since being activated June 27. It's not yet clear if another trip to the injured list could be on the table for Eovaldi due to the back issue.

Wacha came away with a no-decision in Saturday's 3-1 loss to the Marlins, allowing one run on three hits and a walk over six innings. He struck out one.

The veteran righty was actually in line for a 1-0 loss until the Royals pushed across the tying run in the top of the eighth inning. Wacha produced his ninth quality start of the season on 78 pitches (51 strikes), but he's struggled to provide much consistency since the beginning of June, posting a 4.78 ERA, 1.36 WHIP and 35:16 K:BB over his last 43.1 innings, which has resulted in a 1-5 record. He'll try to get back in the win column in his next start, which lines up to come at home next weekend against the Guardians.

Kikuchi did not factor into the decision in Saturday's 9-5 loss to the Phillies, allowing two runs on five hits and three walks with eight strikeouts over five innings.

Kikuchi allowed runs in the first and fifth innings before departing at 91 pitches. The southpaw allowed just three hard-hit balls and generated a whopping 19 whiffs, including 10 on his fastball, but he's now failed to deliver a quality start in any of his four July outings. He'll take a 3.13 ERA, 1.38 WHIP and 123:52 K:BB across 118 innings into a home matchup with the Mariners next week.

Lauer (5-2) picked up the win in Saturday's 6-3 victory over the Giants, allowing two runs on two hits over six innings. He struck out seven without walking a batter.

The southpaw continues to impress at the back of the Blue Jays' rotation. Lauer produced his second quality start of the season on 81 pitches (58 strikes), and he's given up more than two runs in only two of 15 appearances. He'll take a 2.80 ERA, 0.97 WHIP and 65:16 K:BB through 61 innings into his next start, which is scheduled to come on the road next week in Detroit.

Fitts is scheduled to start Tuesday's road game in Philadelphia, Christopher Smith of MassLive.com reports.

After Hunter Dobbins (knee) was ruled out for the season due to a torn ACL, Fitts was called up from Triple-A Worchester on July 12 to fill his spot on the active roster. Fitts went unused out of the bullpen in Boston's final two games before the All-Star break, but he'll assume Dobbins' spot in the rotation to begin the second half. The right-hander could end up being in line for an extended stay in the rotation, as Tanner Houck (elbow) suffered a setback during his rehab assignment and now seemingly isn't a candidate to return from the injured list anytime soon.

Schultz isn't starting as scheduled for Triple-A Charlotte on Saturday due to right knee discomfort, Scott Merkin of MLB.com reports.

Schultz had been slated to start Saturday night, but he isn't going to be able to take the mound due to the knee issue. The lefty prospect was promoted to Charlotte on June 14 and has started three games for the affiliate, struggling to an 11.91 ERA, 2.34 WHIP and 13:8 K:BB over 11.1 innings. It's not yet clear how much time Schultz will need to miss.

The Red Sox returned Houck (elbow) from his rehab assignment Friday, Christopher Smith of MassLive.com reports.

Although Houck's 30-day rehab window is now closed, the fact that Boston has yet to activate him indicates he isn't quite ready to return. The 29-year-old righty posted a 5.74 ERA and 1.53 WHIP across 15.2 innings during his five-start assignment, though he gave up only one run in his final two outings (9.1 IP). He also owns a hefty 8.04 ERA through 43.2 frames in the majors this year, so there's no guarantee he'll have a place in the Sox's rotation whenever he is activated.

The Athletics activated Waldichuk (elbow) from the 60-day injured list Saturday and optioned him to Triple-A Las Vegas.

Waldichuk underwent Tommy John surgery last May and had spent all season on the injured list up to this point. He kicked off a minor-league rehab assignment in late June and tallied a 7.63 ERA, 1.70 WHIP and 17:16 K:BB over 15.1 innings spanning six appearances between Single-A Stockton and Las Vegas. The lefty threw 141 frames for the Athletics in 2023 and could certainly make his way back to the big club in due time, but he'll likely first need to harness his control issues in the minors before getting a look in the MLB rotation.

The White Sox placed Smith on the 15-day injured list Saturday due to a left ankle sprain.

It's not clear when Smith hurt his ankle, though the move is retroactive to July 16 -- one day after the All-Star Game, during which the rookie hurler threw 10 pitches over one-third of an inning. With Smith landing on the IL, Chicago recalled reliever Wikelman Gonzalez from Triple-A, but it's uncertain who (if anybody) will slide into the rotation in the short term. The White Sox have opted for bullpen games on a few occasions this season and could go that route again until Smith is ready to return, which won't be until the beginning of August at the earliest.

The Twins reinstated Matthews (shoulder) from the 15-day injured list Saturday.

After missing more than a month with a shoulder strain, Matthews will return from the IL and start Saturday's game versus Colorado. The 25-year-old is coming off a brilliant minor-league start, during which he struck out nine batters in four shutout frames, and he'll be welcomed back to the big leagues by a Rockies offense that ranks 27th in MLB with a .673 OPS this season. Travis Adams was optioned to Triple-A in a corresponding move.
