Peterson allowed three runs (zero earned) on four hits and no walks while striking out three over five innings in Sunday's 5-1 loss against the Diamondbacks.

Peterson was mostly effective in bulk relief, entering in the third inning and running into little trouble until the sixth, when he allowed three unearned runs following an Andy Ibanez throwing error to open the frame. The southpaw has shown slight improvement over his past two outings, but his season numbers remain underwhelming, as Peterson owns a 5.49 ERA and 1.50 WHIP across 39.1 innings. His next outing is tentatively lined up for Saturday against the Yankees and will likely come behind an opener once again.

Castellanos went 1-for-2 with a two-run home run in Sunday's 3-2 win over the Cardinals.

Castellanos entered off the bench and flew out in his first at-bat in the seventh inning, but the 34-year-old came through in the clutch by blasting a game-tying two-run homer with two outs in the bottom of the ninth against Riley O'Brien. The outfielder owns just a .192 batting average and .560 OPS across 78 plate appearances this season, but he has delivered in key situations, posting a .911 OPS with two homers and 10 RBI when batting with two outs.

Walker went 1-for-4 with a two-run home run in Sunday's 3-2 loss to San Diego.

Walker was the lone source of offense for St. Louis, crushing a towering 425-foot two-run homer off the top deck of the Western Metal Supply Co. building against Walker Buehler in the fourth inning. After struggling mightily over the past two seasons, the 23-year-old outfielder has been firing on all cylinders to begin 2026. Through 39 games, he's slashing .299/.377/.578 with 11 homers, eight doubles, 29 RBI, 31 runs and seven stolen bases.

Pop (calf) began a rehab assignment Saturday, throwing a clean inning for Triple-A Lehigh Valley.

Pop has been sidelined by a strained right calf since mid-April, but he's gearing up for his return to the Phillies. The right-hander will presumably need a handful of rehab outings before Philadelphia considers reinstating him from the injured list. Over 7.1 innings on the year, Pop has a 3.68 ERA, 1.09 WHIP and 6:3 K:BB while working mostly in middle relief.

O'Brien blew the save in Sunday's 3-2 loss to San Diego. He allowed two runs on two hits and no walks while striking out three over one inning.

O'Brien had his club one strike away from securing a series win in San Diego before Nick Castellanos launched a game-tying two-run homer on the ninth pitch of the at-bat in the bottom of the ninth inning. Sunday marked the hard-throwing right-hander's third blown save of the campaign, snapping a streak of four consecutive saves. Despite the stumble, O'Brien has been effective in the closer role in 2026, posting a 2.84 ERA and 0.95 WHIP with 11 saves and a stellar 23:1 K:BB across 19 innings.

Taillon (2-2) took the loss Sunday against the Rangers, allowing one run on four hits and two walks in 5.1 innings. He struck out four.

Taillon hardly deserved the loss in a positive showing Sunday, keeping the ball in the yard for the first time since his first start of the season. The 34-year-old right-hander continued to provide the Cubs with length as well, pitching at least five innings in his seventh consecutive outing. Taillon has a quality 3.94 ERA, 1.14 WHIP and 40:16 K:BB over 45.2 frames, and he should remain worth streaming in most fantasy formats with a matchup against the White Sox on tap for next weekend.

Leahy did not factor into the decision Sunday, allowing two hits and four walks over five scoreless innings against the Padres. He struck out five.

Leahy's control wasn't stellar, as he issued a season-high four walks, but the Padres struggled to string together hits while the right-hander turned in his first scoreless outing of the season. After factoring into the decision in each of his first seven starts (4-3), Sunday marked the 28-year-old's first no-decision of the campaign. He'll carry a 4.31 ERA, 1.59 WHIP and 32:17 K:BB across 39.2 innings into his next start, tentatively scheduled for Saturday against the Royals.

Buehler did not factor into the decision Sunday, allowing two runs on three hits and no walks over six innings against the Cardinals. He struck out two.

Buehler was locked in from the start, retiring the first 11 Cardinals hitters he faced before allowing an Alec Burleson single and a Jordan Walker two-run homer in the fourth inning, the lone blemishes on the hurler's line. The right-hander tied a season low with just two strikeouts, but the lack of whiffs didn't prevent Buehler from turning in one of his better starts of the season. The 31-year-old will carry a 5.20 ERA and 1.35 WHIP with a 31:12 K:BB across 36.1 innings (eight starts) into his next outing, tentatively scheduled for Saturday against the Mariners.

Henderson didn't factor into the decision Sunday against the Yankees, allowing two runs on four hits and one walk in five innings. He struck out five.

The 24-year-old right-hander was taken deep for the first time this season, but it was still a productive outing overall against a tough Yankees lineup. Henderson fired 54 of his 74 pitches for strikes in his third major-league start of 2026, so it looks like Milwaukee is easing him into its rotation. Although he has a shaky 4.15 ERA through 13 innings, Henderson does boast a 16:2 K:BB and 0.92 WHIP and will be looking to crack the 80-pitch marker in his next scheduled start versus the Twins.

Adames went 3-for-6 with a double and two RBI in Sunday's 7-6 extra-innings win over the Pirates.

Adames is starting to come around at the plate, going 10-for-41 (.244) over his last 10 games. He's still racked up 11 strikeouts without a walk in that span, and he's added just two extra-base hits. The shortstop is batting .209 with a .584 OPS, three home runs, eight RBI, 14 runs scored, 12 doubles and one stolen base over 39 contests. Adames isn't in immediate danger of losing his place in the lineup, but the Giants' infield is crowded with top prospect Bryce Eldridge joining the mix earlier this week, which has pushed Casey Schmitt into a utility role. Schmitt can play shortstop and could apply pressure if Adames starts to slump.
