Gage Jump falters again in loss to Marlins

It was a nice rebound outing for Jump, but with the A’s getting shut out, he dropped his third start in a row anyway. While Jump was roughed up in his previous two outings, this makes five times in nine major league starts that he has allowed one or no runs. He’ll take a 3-4 record and a 3.51 ERA into the All-Star break. It’s likely that he’ll face the Nationals next weekend.

This was still kind of impressive from Jump. One of baseball’s best offenses certainly got the better of the 23-year-old, but while free passes could have turned this into a true massacre, he didn’t walk anyone and struck out five. Jump is still 3-2 with a 2.93 ERA and a 40/10 K/BB over 40 innings through seven big-league starts. As tough as the situation is in Sacramento, he’s not a lock to remain useful in mixed leagues over the rest of the season. However, he seems well on his way to becoming an excellent major league starting pitcher. He’ll get the Marlins on Sunday.

It might seem like the A’s have a quality offense this year, but it’s largely a product of their Triple-A ballpark; they came into tonight hitting .266/.351/.462 with 216 runs scored at home and .229/304/.367 with 149 runs scored on the road. Jump would appear to be legit with his 96-mph fastball and plus slider, but with no support in San Francisco tonight, he remained 3-1 with a 2.04 ERA through six starts. He’ll pitch at home against the Dodgers next week. making him a weak play in shallow leagues.

Jump was getting a battle at the end of his outing, throwing eight pitches to Denzer Guzman with two outs in the seventh. However, the last of those saw Vaughn Grissom wander too far off first on a ball in the dirt and get picked off by Shea Langeliers. Jump threw 107 pitches, an unusually high total for a rookie hurler in the year 2026, but he was in control from start to finish, striking out a new high of seven batters in his fifth major league start. He’s allowed a total of four runs in his four starts this month, with three of those coming in Las Vegas last week. He should be just fine to use in San Francisco next week.

Jump got through five scoreless before allowing two singles and a walk to open the sixth. Justin Sterner came in and wound up surrendering a sac fly and a three-run homer to put the A’s down 4-2 and raise Jump’s ERA from 1.93 to 3.05. Even though he was pitching on the moon tonight, Jump still hasn’t allowed a homer in 23 1/3 innings as a major leaguer. He’ll face the Pirates in Sacramento next week.

Jump struck out three and issued three walks in the outing, dropping his ERA to 2.45 through three starts in the big leagues. He’s now pitched into the seventh in back-to-back appearances, both of which came on the road. The 23-year-old rookie southpaw next lines up to face the Rockies at home. It kicks off a 13-game homestand in hitter-friendly Sacramento.

Jump, who gave up four runs in five innings against the Mariners in his first MLB start, allowed just three hits with his average fastball up to 96.9 mph tonight. It was 95.9 mph in his first start and 95.8 mph in Triple-A this season. In spite of that, he still only generated five whiffs on 45 swings. Jump still seems like a tough play in mixed leagues at the moment. He’ll face the Astros on the road on Sunday.

Jump struck out two in a scoreless first inning, then ran into trouble in the second. The Mariners brought three runs across in the frame on four hits and a walk. He stranded two more runners in the third, then allowed another run in on four hits in the fourth. Gage gave the A’s one more scoreless frame, ending his day after five. On the bright side, he only walked one and generated 13 whiffs on 88 pitches to strike out five in his MLB debut. Sacramento certainly isn’t the easiest venue to make your first start. He’ll look for better fortune when he takes on the Cubs in Chicago next Tuesday.

Jump will make his major-league debut on Tuesday against the division-rival Mariners with veteran Luis Severino being pushed back an extra day. The 23-year-old southpaw, who was selected in the second round of the 2024 MLB Draft out of LSU, has compiled a solid 4.50 ERA, 1.47 WHIP and 56/20 K/BB ratio across 38 innings in the hitter-friendly Pacific Coast League this season. He attacks hitters with an unorthodox delivery and a repertoire that features a mid-90s fastball, a strong curveball and multiple slider variations. Jump projects as more of a mid-rotation starter long term, but he misses enough bats to warrant immediate interest in deeper mixed leagues.

Jump, the 73rd overall pick in the 2024 draft, will presumably go right into the rotation. He had a 4.50 ERA in nine starts in Triple-A, but he had struck out 56 while also walking 20 in 38 innings. It seems unlikely that he’ll be a mixed-league solution right away in a tough situation for pitchers in Sacramento, but he has a chance to be a No. 2 or 3 starter for the A’s in the long run.
