Arizona Diamondbacks

Jordan Montgomery had a forgettable night, surrendering six earned runs on seven hits and three walks while striking out only one across two innings in Wednesday's 9-3 loss to the Giants.

Fantasy Impact: This performance ballooned his ERA to 6.80 and WHIP to 1.73, further troubling signs for fantasy managers relying on him. Given his escalating ERA and WHIP, along with a low strikeout rate of 5.63 K/9, Montgomery's reliability as a fantasy starter is increasingly questionable. His inability to limit base runners or miss bats significantly hampers his value in all formats, making him a risky play moving forward.

Pavin Smith went 3-for-4 with a home run, an RBI, and a run scored in the Diamondbacks' 9-3 loss to the Giants.

Fantasy Impact: Smith's performance was a bright spot in an otherwise disappointing game for Arizona. With this outing, Smith's batting average for the season sees a slight uptick, and his ability to connect with the ball, including his third home run of the season, offers some hope for fantasy managers looking for depth in their lineup. While his overall season stats remain modest, performances like this could hint at a potential uptick in production, especially if he continues to secure more consistent at-bats. Fantasy managers should keep an eye on Smith's playing time and performance trends, as he could emerge as a useful waiver wire addition if this trend continues.

Tucker Barnhart is in the starting lineup for the Diamondbacks Wednesday.

Fantasy Impact: Barnhart will handle the catching duties and bat ninth against the Giants. He is hitting .154 with one RBI this season.

Joc Pederson is in the starting lineup for the Diamondbacks Wednesday.

Fantasy Impact: Pederson will serve as the DH and bat third against the Giants. He is hitting .296, with seven home runs, and 20 RBI this season.

Corbin Carroll is in the starting lineup for the Diamondbacks Wednesday.

Fantasy Impact: Carroll will start in center field and bat leadoff against the Giants. He is hitting .192, with two home runs, and 20 RBI this season.

Gabriel Moreno is out of the starting lineup for the Diamondbacks Wednesday.

Fantasy Impact: Moreno will get the day off for rest reasons, with Tucker Barnhart doing the catching and batting ninth against the Giants.

Christian Walker is out of the starting lineup for the Diamondbacks Wednesday.

Fantasy Impact: Walker will get the day off after a 1-for-4 night Tuesday. Pavin Smith will start at first base and bat fifth.

Ketel Marte is out of the starting lineup for the Diamondbacks Wednesday.

Fantasy Impact: Marte will get a day off for rest reasons, with Blaze Alexander moving over to play second base against the Giants.

Paul Sewald delivered a flawless performance against the Giants, securing his sixth save of the season in an 8-5 win.

Fantasy Impact: He threw 17 pitches over a clean inning, allowing no hits or walks while striking out two batters. This outing continues a stellar season for Sewald, who now boasts a 0.96 ERA and a 0.43 WHIP through 10 appearances. His exceptional 10.00 strikeout-to-walk ratio and low BABIP (.100) suggest some luck, but his underlying skills, including a solid 9.6 K/9 rate, indicate he can sustain high-level performance. Fantasy managers should view Sewald as a reliable closing option, especially in leagues that reward saves and strikeouts.

Blake Walston delivered a shaky performance in Tuesday's 8-5 victory over the Giants.

Fantasy Impact: He allowed two earned runs on two hits and four walks while striking out two over 4.1 innings. Despite the Diamondbacks securing the win, Walston's outing was marred by control issues, as evidenced by his four walks and early exit after just 88 pitches. His season ERA slightly rose to 2.84, and his WHIP now stands at 1.42, reflecting ongoing struggles with allowing baserunners. Fantasy managers should be cautious; while his ERA remains respectable, his high WHIP and low strikeout-to-walk ratio suggest potential volatility in his performances moving forward.

Fantasy Impact: Newman will start at shortstop and bat ninth against the Giants. He is hitting .259, with two home runs, and 12 RBI this season.

Fantasy Impact: Saalfrank was one of four players suspended for one year. He bet $445.87 on baseball, with $444.07 of that on MLB-related bets and with a net loss of $272.64 on MLB bets. Saalfrank only won five of his 28 MLB-related bets and lost his $1.80 college bet.

Lourdes Gurriel Jr. went 1-for-4 with a home run and an RBI in the Diamondbacks' 4-2 victory over the Giants.

Fantasy Impact: His solo home run contributed crucially to the team's win, marking his eighth homer of the season. Despite a modest .236 batting average over 55 games, Gurriel Jr.'s power stroke appears to be intact, as evidenced by his consistent RBI production (33 RBI so far). His low walk rate (0.046) and high strikeout rate (0.186) continue to be areas of concern, limiting his on-base potential. However, his ability to drive in runs and hit for power keeps him relevant in fantasy formats that value these categories.

Ryne Nelson delivered a solid outing, allowing two earned runs on six hits over 7.2 innings in Monday's 4-2 victory over the Giants.

Fantasy Impact: He struck out only one batter and issued no walks. Despite the low strikeout total, Nelson's performance was a step in the right direction, especially considering his rocky 5.44 ERA and 1.60 WHIP entering the game. His ability to limit walks in this outing was a positive takeaway, aligning with a decent season-long strikeout-to-walk ratio of 2.46. However, fantasy managers should remain cautious; his low strikeout rate (6.0 K/9) and high BABIP (.356) suggest potential volatility ahead. This start might be a sign of stabilization, but Nelson's fantasy reliability is still questionable at best.
