Outlook Foster Griffin

Foster Griffin looks to maintain solid form in a favorable road matchup against the Diamondbacks.

Foster Griffin has been a stabilizer for the Nationals, posting a sharp 2.45 ERA and 1.00 WHIP with 11 strikeouts over his last 14 days. This strong run is crucial for a Washington squad currently sitting third in the NL East with a 31-32 record and dealing with rotation injuries to Josiah Gray and Jake Irvin. Griffin is locked in as a mid-rotation staple in the third slot of the starting rotation.

While Griffin's 30-day ERA sits at an elevated 5.98, his overall return to the majors has been a success, highlighted by a 3.80 ERA and 1.16 WHIP over 12 starts. This mark is significantly better than his projected rest-of-season ERA of 4.17, suggesting that his recent 14-day resurgence is closer to his true talent level than his mid-May struggles.

Looking at the remainder of the week, Griffin has one scheduled outing on Friday, June 5th, on the road against Arizona. He will match up against Merrill Kelly, who has struggled with a 5.06 ERA and a 1.46 WHIP. Given this favorable matchup against a vulnerable opposing pitcher, fantasy managers should confidently deploy Griffin. Verdict: Start.

Includes Detailed Projections

Outlook Jack Leiter

Jack Leiter's strikeout surge makes him an appealing fantasy option as he prepares for a weekend home start against Cleveland.

Leiter is in spectacular form, highlighted by a dominant 10-strikeout performance on May 31. Over his last 30 days, he has posted a 2.96 ERA and 1.28 WHIP with 31 strikeouts across 27.4 innings, cementing his place as a back-end starter in the rotation. His high-octane stuff provides a massive boost to the 30-32 Rangers.

This recent stretch is a major step forward from his 4.50 ERA this year and 3.98 ERA last year. While his 10.41 K/9 indicates elite swing-and-miss upside, our season models project him to settle around a 4.33 ERA and 1.28 WHIP over 156.0 innings. Expect minor ratio regression, but his strikeout volume remains highly sustainable.

Leiter is scheduled to make a single home start on Saturday, June 6, against the first-place Guardians. He will face Tanner Bibee, who has struggled to a 4.57 ERA and a 1.30 WHIP. Given Leiter's outstanding form and a favorable matchup against a winless starter, he is primed for success. Verdict: Start.
