Griffin Jax Fantasy Stats

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.

Tampa Bay Rays right-hander Griffin Jax got off to a rough start to the 2026 season, allowing eight runs across his first two innings (four games) of the year. However, Jax has been significantly better since Tampa Bay shifted him from the bullpen to the starting rotation in late April. Across 21 innings (six starts) since the role shift, Jax has recorded a 1.71 ERA and 1.19 WHIP with 17 strikeouts. The 31-year-old also worked five innings in two consecutive starts before being limited to two innings after getting hit in the back by a comebacker in his most recent outing. Now that Jax should be built up close to a regular starter's workload, the right-hander carries significant waiver wire appeal across most fantasy league formats.

Tampa Bay Rays right-hander Griffin Jax (back) is in line to make his next scheduled start on Monday against the Detroit Tigers, per Evan Woodbery of MLive Media Group. Jax was forced to exit early from his start against the Baltimore Orioles on Tuesday after being hit in the back with a 107.2 mph comebacker. In 17 appearances (six starts) for Tampa Bay so far in 2026, Jax is 1-3 with a 3.60 ERA, 1.40 WHIP, and 27 strikeouts across 30 innings. The 31-year-old was moved from the bullpen to the rotation in late April and has been effective since, allowing four earned runs over 21 innings. He had reached five innings pitched in each of his last two starts leading into Tuesday, and should be stretched out to close to a normal starter's workload going forward. In leagues where he's not already rostered, Jax could be worth a look on the waiver wire.

Tampa Bay Rays right-hander Griffin Jax (back) was hit by a comebacker on Tuesday in his start against the division-rival Baltimore Orioles and was forced to exit the game early due to a back contusion, according to Marc Topkin of the Tampa Bay Times. Jax is considered day-to-day after taking a 107.2 mph line drive off his back in the second inning. The 31-year-old tried to stay in the game, but he only made it through two frames before being pulled and ended up allowing three unearned runs on three hits while walking none and striking out three. We won't know more about whether Jax can make his next scheduled start until after he goes for testing. Jax began the year in Tampa as their closer with Edwin Uceta (shoulder) out, but he quickly was demoted from the closer's role after blowing each of his first two save chances. Tampa has transitioned Jax to a starting role, with Tuesday being his sixth start. He's been much more effective as a starter, going into Tuesday's game with only four runs (three earned) allowed with eight walks and 14 strikeouts in 19 innings over five starts.
