Gage Jump Fantasy Stats

Athletics rookie left-hander Gage Jump (shoulder) is likely heading to the 15-day injured list, which would end his first year in the majors a bit early, according to Jason Burke of Inside the A's. The determination will be made on Tuesday. Jump dealt with shoulder tightness in his last start on Saturday against the division-rival Seattle Mariners, when he allowed five earned runs on five hits (two homers) while walking one and striking out only two in two innings for his 11th loss of the season. The 23-year-old southpaw, a former second-rounder in 2024 from LSU, definitely had his ups and downs in the first 20 starts of his major-league career with a bad team. In his 98 2/3 innings pitched, Jump has gone 6-11 with a 5.47 ERA (4.02 FIP) and a 1.52 WHIP with 108 strikeouts and 46 walks. He had an especially tough time at home at Sutter Health Park, posting a 6.27 ERA with 56 strikeouts and 27 walks in 51 2/3 frames. Jump has some intriguing skills but will need to show better command of his arsenal to take the next step with the A's in 2027.

Athletics rookie left-hander Gage Jump showed his upside on the mound in Saturday's 7-3 win over the red-hot Boston Red Sox at Fenway Park, allowing only two earned runs on six hits while walking two and striking out a career-high 11 hitters in six innings for his fifth win of the year. It was Jump's fifth quality start in his first 14 major-league starts for the A's. The young southpaw has been up and down since the All-Star break, going six innings in two of his four starts and allowing 12 runs in 8 1/3 innings pitched in the other two appearances. Through his first 14 starts in the big leagues, Jump now sports a 4.46 ERA, 1.46 WHIP and 84:33 K:BB in 72 2/3 innings pitched. Jump will have a middling matchup his next time out against the division-rival Texas Rangers, a team that he has yet to face so far in his first season in the majors. Jump has a decent 25.3% strikeout rate and plenty of upside in that department, but unsurprisingly, his command has been spotty with a 10.8% walk rate going into his start in Boston on Saturday.

Athletics left-handed starting pitcher Gage Jump has been knocked around in July, but the strikeouts keep showing up. He fanned eight over 3 2/3 innings against Washington on Friday, July 17, while allowing four runs, three earned. Jump now has a 7.30 ERA and 1.95 WHIP through three July starts. Ugly, yes. He also has 16 strikeouts in only 12 1/3 innings during that stretch. His full major-league line looks much better: a 3.78 ERA, 1.32 WHIP, and 56 strikeouts against 17 walks over 52 1/3 innings. The fastball averages 96.3 mph, and the swing-and-miss ability gives him a reason to remain patient. Jump is rostered in just 29% of Yahoo leagues. Tough home matchups may require some discretion, but he still belongs on rosters in 10-team formats for managers who need strikeouts.

Athletics left-hander Gage Jump finished the first half of the 2026 season 3-4 with a 3.51 ERA, 1.29 WHIP, and 48 strikeouts in 48 2/3 innings pitched (nine starts). This is Jump's first taste of MLB, and overall he has been fairly solid, especially given that he pitches half his games at Sutter Health Park, one of MLB's friendliest ballparks. That being said, Jump has pitched to a 6.20 ERA at home and a 0.75 ERA on the road, so it's been night and day for him, so something fantasy managers will want to continue to monitor moving forward as they make weekly start/sit decisions. When we peek under the hood, most of Jump's ERA estimators support his strong start to his career, with a 3.96 xERA and 3.31 FIP. When you combine that with his solid control and strikeout upside (48:15 K:BB ratio), Jump has proven to be useful in all formats. Some may argue there is even more to be had, as his strikeout rate in the Minors was 33.1 percent in Triple-A this year, and 28.4 percent in Double-A in 2025. Jump should continue to be rostered in all formats for the second half, but should be considered a strong start when he's on the road, and a consideration to sit when at home.

Athletics rookie left-hander Gage Jump has proven himself to be pretty effective in his first seven major-league starts, going 3-2 with a 2.93 ERA (2.66 FIP) and 1.12 WHIP with 40 strikeouts and 10 walks in 40 innings pitched. The 23-year-old former second-round selection in 2024 out of Louisiana State University hit a road bump in his most recent outing, though, giving up a season-high five earned runs on 11 hits (two homers) while walking none and striking out five on June 29 against the Los Angeles Dodgers. It broke a string of two straight scoreless appearances against the Los Angeles Angels and San Francisco Giants in which he struck out 16 and walked only four. We'll give Jump a pass against the back-to-back World Series champions in what was just his seventh major-league start. The A's No. 3 prospect, per MLB Pipeline, has plenty of upside with a 25% strikeout rate and 6.3% walk rate, although he'll be much riskier as a fantasy streamer at home at hitter-friendly Sutter Health Park. In four starts in Sacramento, Jump has a 4.98 ERA with 26 hits allowed, compared to a 0.49 ERA in two road starts so far.

Athletics rookie left-hander Gage Jump has made an immediate impact in his first six major-league starts, allowing only eight earned runs on 24 hits (zero homers) while walking 10 and striking out 35 in 35 1/3 innings pitched. The 23-year-old 6-foot, 200-pound southpaw is the A's No. 3 prospect, per MLB Pipeline, and he has so far lived up to the expectations since joining the big-league squad. The former second-round pick in 2024 out of Louisiana State University had a second straight scoreless appearance on Wednesday against the San Francisco Giants by tossing five scoreless innings with one walk and a career-high nine strikeouts in a no-decision. Jump has held the opponent scoreless in half of his six starts so far and has yet to allow a home run. That won't last forever, especially in the hitter-friendly environment in Sacramento, but his strong start is definitely attracting interest off the waiver wire in fantasy baseball leagues. Jump has a tough matchup his next time out against the Los Angeles Dodgers, but managers who need pitching depth should consider picking the young lefty up. He's currently rostered in 54% of Yahoo leagues.

Athletics left-hander Gage Jump was lights-out on Thursday night at home against the Los Angeles Angels, throwing seven shutout innings of zero-run ball, racking up seven strikeouts, and allowing only one hit. This season, and in his career, Jump has now made five starts for the Athletics and has an excellent 2.37 ERA and 0.99 WHIP in 30 innings pitched (five starts), with a 22 percent strikeout rate. While his strikeout rate is lacking, he did have a 33.1 percent strikeout rate in Triple-A this season and a 28.4 percent strikeout rate in the Minors last year across Double-A and High-A, meaning there is more room for improvement at the Major League level. Nonetheless, he has been spectacular for the Athletics, and the 23-year-old has become a must-add player in all formats due to his production thus far and the upside he could show if he starts generating more whiffs and strikeouts, as he has at other levels of his professional career. Up next for Jump is a road game against the San Francisco Giants.

Athletics rookie left-hander Gage Jump, who is considered the team's No. 3 prospect per MLB Pipeline, has more than held his own in his first four major-league starts. The 23-year-old former second-round pick in 2024 out of Louisiana State University has gone 2-1 with a 3.09 ERA (2.51 FIP) and 1.11 WHIP with 19 strikeouts and six walks in 23 1/3 innings pitched. The young southpaw allowed four earned runs in five innings to the Seattle Mariners in his MLB debut on May 26, but he followed that up with two quality starts versus the Chicago Cubs and Houston Astros. At the hitter-friendly minor-league venues of Sacramento and Las Vegas, Jump has surrendered seven runs in 10 innings in two starts, while he's been much better on the road. In shallow-mixed fantasy leagues, fantasy managers should keep an eye on Jump, while in deeper leagues, he's worth considering off the waiver wire as a matchup-based streamer. He has pitched well enough so far to keep his rotation spot once Aaron Civale (shoulder) returns from the injured list.

Athletics left-hander Gage Jump made his major league debut on May 26 and has shown the kind of stuff that made him a notable pitching prospect coming out of LSU. Through his first two big-league starts, Jump owns a 3.75 ERA with 10 strikeouts across 12 innings. He bounced back from a shaky debut by holding the Chicago Cubs to one run over seven innings Tuesday, allowing three hits and one walk while striking out five to earn his first MLB win. He has shown the ability to miss bats with a fastball that sits 93-96 mph and a sharp slider. Jump's fantasy appeal comes from the strikeout upside he showed before his promotion. The 23-year-old recorded 56 strikeouts in 38 innings over nine starts at Triple-A Las Vegas, giving him enough swing-and-miss ability to matter if he sticks in the Athletics' rotation. The sample is still small, and young pitchers on struggling teams can be volatile, but Jump is worth a speculative add on the waiver wire in leagues with 12 teams or more for managers looking for starting pitching help.

Athletics pitching prospect Gage Jump made his MLB debut last Tuesday against the Seattle Mariners, allowing nine hits and four earned runs while striking out five across five innings of work. While the 23-year-old's first start in the majors was a bit of a struggle, he remains a potentially intriguing starting pitching option for fantasy managers. Across 38 innings (nine starts) with Triple-A Las Vegas before his promotion, Jump pitched to a 4.50 ERA and 1.47 WHIP with 56 strikeouts. Particularly given that he will be making his home starts in the hitter-friendly Sutter Health Park, Jump may not provide much value in the ERA and WHIP categories for fantasy managers. However, the young lefty carries significant strikeout upside after posting strikeout rates of 33.1% and 28.4% in the minors in 2026 and 2025, respectively. Fantasy managers in need of whiffs may want to consider targeting Jump on the waiver wire ahead of a potential breakout.
