Griffin Jax Fantasy Stats

Tampa Bay Rays starting pitcher Griffin Jax has settled into a full-time rotation role and now owns a 3.74 ERA, 1.23 WHIP, and 92 strikeouts across 86 2/3 innings. He struck out 10 Texas Rangers while allowing one earned run on five hits and three walks over 5 2/3 innings Tuesday, although Tampa Bay's quiet offense left him with the loss in a 4-1 game. The occasional blowup remains the concern, most recently when Boston tagged Jax for seven runs on July 17. His strikeout ability, stable workload, and SP/RP eligibility still make that risk worth accepting. RotoBaller's Week 18 rankings had Jax on 53% of Yahoo rosters and placed him 20th overall with an add recommendation for leagues of 10 teams or deeper. He is too valuable to remain available at that league depth.

Tampa Bay Rays right-hander Griffin Jax may have taken a loss on Tuesday against the Texas Rangers, but the 31-year-old former reliever was still dominant for fantasy managers. Jax allowed two runs (one earned) on five hits while walking three and striking out a season-high 10 hitters in 5 2/3 innings pitched for his eighth loss of the year in the 4-1 defeat at Tropicana Field. The 31-year-old reliever turned starter is now sporting a 3.74 ERA and 1.23 WHIP with a 92:30 K:BB in his 86 2/3 innings pitched in his sixth major-league season (first full year in Tampa). Jax blew his first two save chances to open the 2026 campaign as the Rays' primary closing option, and Tampa eventually moved him to the starting rotation, where he's been more valuable in fantasy baseball. Since joining the rotation on April 26, Jax has gone 5-5 with a 3.38 ERA (3.83 FIP) with 72 strikeouts and 20 walks in 72 innings across 16 starts. He allowed a season-high seven earned runs in five innings against the Boston Red Sox on July 17, but since then, he's given up just two earned runs with two walks and 15 K's in two starts versus the Rangers and Toronto Blue Jays.

Tampa Bay Rays starting pitcher Griffin Jax bounced back from a rough outing with six strong innings against Toronto on Wednesday, July 22. He allowed one run on three hits and one walk, struck out five, and earned his sixth win. Jax had been tagged for seven earned runs by Boston in his previous start, but the response brought his season line to a 3.89 ERA, 1.22 WHIP, and 82 strikeouts over 81 innings. The move from the bullpen has stuck, with Jax now up to 16 starts in 27 appearances. He also carries SP/RP eligibility, making those innings easier to fit into fantasy lineups. Jax appears on 53% of Yahoo rosters, while RotoBaller ranks him as a 10-team addition. One blowup should not erase the larger body of work. Jax should not remain available in competitive mixed leagues.

After a disappointing beginning to the 2026 season while working out of the bullpen, Tampa Bay Rays right-hander Griffin Jax has found success since being moved into his team's rotation in late April. Across 24 appearances (13 starts) on the year, Jax has recorded a 4-6 record with a 3.60 ERA, 1.22 WHIP, and 68 strikeouts in 65 innings pitched. Dating back to June 7, Jax owns a 3-2 record with a 2.32 ERA, 0.94 WHIP, and 36 strikeouts across 31 innings (six starts). In that span, Jax owns a 30.3% strikeout rate with just a 5.0% walk rate, good for an elite 25.3% K-BB rate. In any fantasy league where Jax is not already rostered, he profiles as a priority waiver wire pickup.

Tampa Bay Rays right-hander Griffin Jax strengthened his case as a waiver-wire pickup in his latest outing at home against the division-rival New York Yankees at Tropicana Field. Jax took his sixth loss of the year in a 5-1 defeat and allowed three earned runs, but he gave up just one hit (a three-run homer to utility man Jose Caballero), walked two, and struck out a career-high 10 batters on the night. The 31-year-old retired the first 13 batters he faced, but he ran into trouble in the fifth frame with two walks before giving up a three-run jack to Caballero that opened the game up for the Yanks. Jax threw 51 of his 81 pitches for strikes and generated 16 swings and misses from Yankees hitters. He's now at a 3.60 ERA on the year with a 1.22 WHIP in 65 innings in what has been a successful transition from the bullpen to the starting rotation in Tampa. He's rostered in 61% of Yahoo leagues and is slated to make his final start of the first half this weekend at home against the Seattle Mariners. Since becoming a full-time starter on April 26, Jax has gone 3-3 with a 2.65 ERA (4.09 FIP) with 48 strikeouts and 13 walks in 51 innings pitched.

Tampa Bay Rays pitcher Griffin Jax has been making a smooth transition into the starting rotation. Over his last five outings, Jax owns a 1.73 ERA with 27 strikeouts across 26 innings of work. Jax was tagged for three runs across six innings of work during his most recent outing against the Kansas City Royals on Wednesday. The right-hander has looked sharp as a starting pitcher and figures to remain in that role going forward. His next outing is scheduled in Houston versus the Astros. Fantasy managers seeking pitching help should check the waiver wire to see if Jax is available.

After opening 2026 in a relief role, Tampa Bay Rays right-hander Griffin Jax was moved to the starting rotation in late April. It took a few outings for Jax to ramp up to a full starter's workload, but he's started to come into his own in recent weeks. Dating back to June 7, Jax has allowed just two earned runs while recording 21 strikeouts and two wins across 20 innings (four starts). For the season overall, the 31-year-old is averaging 96.5 miles per hour on his fastball and has pitched to a 3.33 ERA and 1.31 WHIP across 54 innings. Jax has yet to go more than exactly five innings in a start, which limits his production upside to some degree. Still, his effectiveness since joining the Rays rotation makes him a quality starting pitcher streamer for fantasy managers to target on the waiver wire.

Tampa Bay Rays pitcher Griffin Jax earned his third win of the season on Wednesday and continues to prove himself as a very solid pickup from the waiver wire. Jax went five innings and gave up five hits while racking up seven strikeouts. He has worked exactly five innings in four straight outings, going 2-1 with a 0.90 ERA, 3.05 FIP, and a 1.05 WHIP. Jax has successfully moved from the bullpen to the starting rotation, and he can be a great way to fortify your rotation, even though his innings aren't maxed out yet. His next start is scheduled for Tuesday on the road in Kansas City, and he will likely be a two-start pitcher for that week since he'll turn around and face the Astros the following Sunday.

Tampa Bay Rays right-handed pitcher Griffin Jax is becoming a more useful fantasy option as he settles into a starting role. Across 44 innings, the 31-year-old owns a 1-5 record, 3.68 ERA, 1.36 WHIP, and 41 strikeouts. The overall WHIP is not ideal, but Jax has been better since moving into the rotation, posting a 3.00 ERA, 1.30 WHIP, and 27 strikeouts over his last seven starts. Over his last two outings, Jax has been even sharper, not allowing an earned run with a 1.00 WHIP (across 10 frames). The former high-leverage reliever also brings high-end whiff potential after recording 99 strikeouts out of the bullpen last season. Workload remains the main caveat, as Tampa Bay has been careful while stretching him out, which may limit his win upside in the short term. The 32% Yahoo roster rate keeps the door open in many leagues, making Jax a viable deeper-format target for managers looking for rotation help with emerging strikeout appeal.

Tampa Bay Rays right-hander Griffin Jax put together a strong outing on Sunday against the Miami Marlins, striking out four across five scoreless innings. It was a much-needed bounce back for Jax, who was bludgeoned by the Detroit Tigers for six earned runs over four innings in his first start of June. Outside of the rough day against Detroit, Jax has performed well since being moved from the bullpen to the rotation in late April. The 31-year-old has allowed one earned run or fewer in six out of his eight starts and has gone at least five innings in three out of his last five appearances. Jax may not offer tremendous upside for fantasy managers, but he's steadied himself after a slow start to the year in the bullpen and could be a valuable deep-league streaming option as a starting pitcher.
