Jax Shines in Starting Role Amid Rotation Injuries

Griffin Jax has been outstanding over his last 14 days, tossing 10 scoreless innings with a 1.00 WHIP and nine strikeouts. He currently slots in as a back-end starter for the second-place Rays, who are looking to snap a three-game losing streak. Jax's role in the rotation is secure for now with Ryan Pepiot and Jesse Scholtens sidelined by injuries.

While his recent scoreless streak is spectacular, our models project a more realistic 3.36 ERA and 1.10 WHIP for Jax over the rest of the season. His elite strikeout ability from his relief days remains, but fantasy managers should expect some regression as his pitch counts and workloads increase. Still, his transition back to a starting role looks entirely legitimate.

Looking at the remaining schedule for this week, Jax is scheduled to start at home on June 19 against Washington. He draws a highly favorable matchup against Cade Cavalli, who carries a shaky 1.39 WHIP this season. Fantasy managers should comfortably deploy Jax in all formats for this single-start week. Verdict: Start.

Outlook Roki Sasaki

Roki Sasaki seeks redemption after a rocky start as he prepares for a favorable home matchup

Sasaki suffered a setback in his last outing, allowing seven earned runs over 4.1 innings to run his weekly ERA up to 15.37. However, the first-place Dodgers (48-27) rely heavily on him with rotation mates Tyler Glasnow and Blake Snell on the injured list. His velocity remains elite, touching 100 mph as he looks to steady the ship.

Sasaki's 4.84 season ERA is inflated by a few rough starts, but our season projection of a 4.08 ERA and 1.28 WHIP is closer to his true talent. With a revamped splitter grip and a high strikeout rate of 10.61 K/9 over the last 30 days, his dominant stuff suggests positive regression is coming. He remains a high-upside asset as his command stabilizes.

Sasaki is scheduled for a single start on June 19 at home against the Orioles. He matches up against Trey Gibson, who carries a 5.91 ERA and a 1.59 WHIP, giving the Dodgers a significant advantage. Lock him in as a strong option to close out your fantasy matchup. Verdict: Start.
