Griffin Jax Fantasy Stats

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.

Rays right-hander Griffin Jax has taken a major step forward since transitioning into a starting role in late April, quickly emerging as a high-upside fantasy target. The 31-year-old owns a 2.11 ERA across his last seven appearances after struggling out of the bullpen early in the season. Jax now carries a 3.54 ERA and 1.36 WHIP overall, but his underlying profile has improved significantly as a starter. While his strikeout rate has dipped slightly, he has generated groundballs at over a 50 percent clip, allowing him to work deeper into games and limit damage consistently. Jax appears far more comfortable in the rotation, and fantasy managers should strongly consider adding him before his value rises further.

Tampa Bay Rays right-hander Griffin Jax continues to climb fantasy rankings after another strong outing on Tuesday. Jax allowed one earned run across five innings while striking out six batters against the Houston Astros. Since moving into the rotation in late April, the 31-year-old has posted a 1.62 ERA and 1.14 WHIP across four starts in May. Despite operating with a limited pitch count, Jax has consistently worked deep into games and continues to earn the trust of Tampa Bay's coaching staff. Jax originally entered the league as a starter in 2021 before spending four seasons in the bullpen. Fantasy managers searching for pitching help should move quickly as Jax continues establishing himself as a reliable rotation option.

Tampa Bay Rays right-hander Griffin Jax will make the start for the Rays on Thursday against the Red Sox in Boston, according to Marc Topkin of the Tampa Bay Times. This will be Jax's third straight "start" for Tampa. The Rays could potentially be looking to stretch Jax out as a traditional starting option after left-hander Steven Matz (elbow) landed on the injured list on Tuesday, but for Thursday's outing in Beantown, Jax most likely won't go deep enough in the ballgame to be a worthwhile streaming option for fantasy managers. In his last two opening assignments, Jax has tossed five shutout innings with two hits allowed, two walks, and four strikeouts against the Minnesota Twins and San Francisco Giants. The 31-year-old veteran opened the year as Tampa's go-to closer with Edwin Uceta (shoulder) on the shelf, but he struggled in that role and was demoted quickly. Overall, he has a 5.14 ERA, 1.50 WHIP, and 14:9 K:BB in 14 innings over 13 outings (two starts) in 2026. If Jax continues to get stretched out as a starter, he'll be worth a look off the waiver wire in deeper leagues for fantasy managers in need of rotation depth. Jax is rostered in 25% of Yahoo leagues currently.

Tampa Bay Rays relief pitcher Griffin Jax got off to a disastrous start to the 2026 season, allowing five earned runs across his first four outings (two innings pitched). The 31-year-old has stabilized his numbers to some degree since then, posting scoreless outings in five out of his last seven appearances. Still, Jax owns an 8.00 ERA and a 1.89 WHIP across nine innings pitched on the year. Jax's strikeout rate is down from 35% to 22.7%, while his 15.9% walk rate is more than double his 7.4% rate from 2025. The Rays' closer job remains largely up for grabs with the news that reliever Edwin Uceta (shoulder) experienced a setback in his recovery from a shoulder injury. Jax could eventually work his way back into the ninth-inning mix, but his early-season struggles make him very difficult for fantasy managers to rely on with any degree of confidence.

Tampa Bay Rays reliever Griffin Jax has gotten off to a nightmare start to the 2026 season. Across two innings (four games), the 31-year-old has allowed five hits, five earned runs, and two walks while recording just one strikeout. With fellow Rays right-hander Edwin Uceta (shoulder) on the injured list, Jax opened the year with a chance to emerge as Tampa Bay's preferred ninth-inning option. However, Jax has already blown two saves and may have pitched his way out of high-leverage opportunities. Jax has posted K-BB rates north of 27% in each of the last two seasons, so he has upside if he can settle in and find his prior form. Still, fantasy managers should be aggressive in search for other relief options off the waiver wire, given Jax's poor performance thus far. Rays relievers Bryan Baker and Garrett Cleavinger look like the favorites for saves in Tampa Bay until Uceta returns.
