Mazur (0-2) took the loss against the Mets on Saturday, allowing two runs on three hits and six walks while striking out four batters over 3.2 innings.

Advice: Mazur has struggled to find the strike zone through his first three big-league outings, racking up 13 walks over 12.2 frames. Surprisingly, none of Mazur's career-high six free passes Saturday resulted in a score -- the rookie managed to wiggle out of a constant stream of baserunners until a pair of Mets doubles in the fourth inning resulted in New York's first run. Nonetheless, Mazur isn't likely to find major-league success if he continues to issue free passes at his current rate, and he could be pushed out of San Diego's rotation if Yu Darvish (groin) is able to return to action next week.

Walker (4-3) allowed an unearned run on a hit and a walk with one strikeout over one inning to take the loss Saturday versus the Angels.

Advice: Walker's scoreless streak ended at 5.1 innings, though a two-out throwing error by Curt Casali contributed to the Giants giving up the decisive run in the seventh inning. Walker has allowed four runs (three earned) over 7.1 innings in June, and he's added four holds this month as he continues to see an increasingly large high-leverage role. He's at a 2.48 ERA, 0.96 WHIP and 46:7 K:BB with 13 holds over 36.1 innings this season. While it hasn't happened yet in 2024, Walker would likely be next in line for save chances whenever Camilo Doval is unavailable, as Tyler Rogers has typically struggled when given ninth-inning assignments.

Criswell allowed two runs on three hits and two walks while striking out six over four innings in a no-decision versus the Yankees on Saturday.

Advice: The Red Sox jumped out to a quick lead, but Criswell didn't pitch deep enough to qualify for the win. He needed 88 pitches (55 strikes) to complete his four frames, making this the seventh time in 12 appearances (11 starts) he's failed to complete five innings. The 27-year-old has a 4.15 ERA, 1.21 WHIP and 49:13 K:BB over 52 innings this season. Criswell is tentatively projected to make his next appearance on the road versus the Reds.

Arrighetti (3-6) allowed seven runs on five hits and two walks while striking out two over 1.1 innings to take the loss versus the Tigers on Saturday.

Advice: Arrighetti was moved up a day when Justin Verlander (neck) was scratched from his scheduled start. The result was disastrous for the Astros, as Arrighetti gave up three home runs in his shortest outing of the season, though the Astros came into Saturday with a well-rested bullpen. The rookie right-hander has not made a good impression in the majors this year with a 6.37 ERA, 1.71 WHIP and 63:31 K:BB over 53.2 innings through 12 starts. With the Astros' rotation already thin, it's likely Arrighetti sticks around for his next start, which is tentatively scheduled to be a tough home matchup versus the Orioles.

Abbott (5-6) took the loss against Milwaukee on Saturday, allowing three runs on four hits and three walks while striking out three batters over five innings.

Advice: Abbott navigated around a stream of baserunners to keep the Brewers off the scoreboard for four frames, but he put himself in quick danger by walking the first two batters in the fifth. That came back to hurt him in a big way when Joey Ortiz hit a changeup for a three-run homer, accounting for all the runs Abbott surrendered in the outing. It was the southpaw's second straight start of five frames after he went at least six innings in four consecutive outings between May 15 and June 3. Abbott has fared reasonably well this season with a 3.42 ERA and 1.20 WHIP, though his 60:25 K:B over 79 frames doesn't help his fantasy stock. Rotowire.com Yesterday, 7:41 pm
