The Nationals recalled Alvarez from Triple-A Rochester on Monday.

Alvarez will start Monday's game in Philadelphia. The left-hander had not made an appearance for Rochester after being sent there one week ago, so he'll be taking the ball Monday on six days' rest. Alvarez has logged a 4.06 ERA, 1.51 WHIP and 58:28 K:BB over seven starts and eight relief outings with the Nationals this season.

The Giants acquired Marquez and right-hander Marty Gair from the Phillies on Monday in exchange for infielder Luis Arraez and right-hander Caleb Kilian, Mark Feinsand of MLB.com reports.

The main prize in the two-prospect haul heading to San Francisco, Marquez had emerged as one of the top lower-level arms in the Philadelphia farm system in 2026. Between stops at Single-A Clearwater and High-A Jersey Shore, the 20-year-old righty has compiled a 1.68 ERA, 0.81 WHIP and 33.3 K-BB% over 59 innings. Marquez is likely to report to the Giants' High-A affiliate in Eugene.

Sheehan (4-8) took the loss Sunday, allowing five runs on six hits, a walk and a hit-by-pitch over 2.2 innings against the Red Sox. He struck out four.

Sheehan couldn't settle in, permitting two runs in the first inning before giving up a trio of solo homers in a third frame that he failed to complete. Sunday marked the right-hander's second-shortest outing of the year and the third time he has surrendered five-plus runs in a game. It's been an incredibly disappointing campaign for the 26-year-old, who owns a 5.29 ERA, 1.29 WHIP and 108:30 K:BB across 95.1 innings (20 starts). Sheehan is lined up to make his next start on the road against the Diamondbacks next weekend, though his spot in the rotation could come into question with the addition of Tarik Skubal and the impending return of Blake Snell (elbow).

Assad is slated to start Tuesday's game against the Dodgers at Wrigley Field, Jesse Rogers of ESPN.com reports.

Assad earned himself a second straight turn through the rotation after he struck out six and allowed one earned run on six hits and two walks in 4.1 innings in a start against the Cardinals on Thursday. The right-hander could have a longer leash Tuesday after tossing just 83 pitches versus St. Louis, but he'll also get a tougher matchup, taking on a Dodgers offense that has posted an MLB-best 113 wRC+ on the season. In addition to facing off against a tough lineup, Assad's chances of earning a win will be further dimmed by going head-to-head with two-time Cy Young Award winner Tarik Skubal, who will make his Dodgers debut Tuesday.

President of baseball operations Andrew Friedman said that Skubal will make his Dodgers debut Tuesday against the Cubs at Wrigley Field, Jack Harris of the California Post reports.

The Dodgers made their acquisition of Skubal official Sunday, with the Tigers receiving three prospects -- outfielders Zyhir Hope and right-handed pitchers River Ryan (hamstring) and Brady Smith -- in exchange for the two-time Cy Young Award winner. Before becoming an unrestricted free agent this summer, the 29-year-old Skubal will headline the Los Angeles rotation over the final two months of the regular season and during the playoffs while the club pursues its third consecutive World Series title. Skubal missed about six and a half weeks earlier this season after requiring a NanoScope surgery to remove a loose body from his left elbow, but he hasn't missed a beat since returning to action June 13. He logged a 2.87 ERA, 0.88 WHIP and 71:8 K:BB over 53.1 innings in his final nine starts with Detroit after coming off the injured list.

Alcantara (12-6) notched win Sunday against the Mets, allowing no runs on four hits and two walks in six innings. He struck out five.

That makes it back-to-back scoreless starts for Alcantara, who continues to be a workhorse for the Marlins in 2026. The right-hander has reached the 90-pitch mark in all but two of his 24 outings -- reaching the 100-pitch plateau in half of them -- and he's now thrown at least six innings in six consecutive appearances and 11 of his last 12. Alcantara is set to bring a 3.68 ERA, 1.20 WHIP and 120:41 K:BB over 156.2 frames into a soft home matchup against the Angels.

Stock (0-1) took the loss Sunday against the Marlins, allowing one run on three hits and no walks in five innings. He struck out four.

The Mets traded away Freddy Peralta earlier Sunday, but Stock filled in admirably during what was his first major-league start since 2021. The journeyman right-hander held Miami scoreless until the fifth inning, with the lone blemish on his line being a Joe Mack solo home run. New York has an open rotation spot now that Peralta has been dealt, and Stock figures to have earned himself another opportunity with the big-league club next week against Pittsburgh.

Burns (13-1) notched the win Sunday against the Pirates, allowing one run on two hits and two walks in six innings. He struck out nine.

Pittsburgh managed to scratch a run across in the fourth inning, but Burns was his usual dominant self otherwise Sunday. The first-time All-Star has now fanned at least six in 15 of his 21 starts this season, and he's remarkably worked at least five innings while giving up two runs or fewer in all but three of his outings. Burns has an exceptional 2.35 ERA, 1.10 WHIP and 137:43 K:BB over 118.2 innings, but he has a tough test in Washington lined up for his next appearance.

Keller (6-8) took the loss Sunday against the Reds, allowing seven runs on six hits and four walks in two innings. He struck out two.

Keller lacked both control and command Sunday, tying a season high in walks and serving up a pair of home runs. The seven runs allowed matched a season worst for the right-hander, who also turned in his shortest outing of the season while recording his second-fewest strikeouts of the campaign. Keller will be trying to pick up the pieces his next time out against the reeling Mets, holding a 5.29 ERA, 1.37 WHIP and 89:42 K:BB over 115.2 innings.

Roupp (7-10) took the loss Sunday, allowing five runs on six hits and four walks over 4.2 innings against the Padres. He struck out six.

Roupp was done in by a four-run second inning, surrendering a two-run homer to Jackson Merrill while walking three batters during the frame. The right-hander has taken a step back over his past two starts, allowing four runs and taking the loss in both outings. Sporting a 4.34 ERA, 1.29 WHIP and 120:52 K:BB across 118.1 innings (22 starts), Roupp will look to get back on track next weekend against the Tigers.
