2025 Fantasy Outlook
Erceg posted a 3.68 ERA and 41:13 K:BB over 36.2 innings for the Athletics before the team capitalized on the prices being paid in the relief market, trading him to Kansas City at the end of July. The 29-year-old former infielder was even more impressive for the Royals, posting a 2.88 ERA and 0.84 WHIP with 31 strikeouts against only three walks across 25 innings. After tallying only three saves with the A's, Erceg racked up 11 of Kansas City's 15 saves after the team acquired him. He went slider heavy as he moved into the closer role, increasing his usage of the pitch by 13.2 percent compared to 2023. Conversely, he tossed fewer changeups, which was his best pitch the year prior. Erceg is under team control through 2029 and was the favorite to open 2025 as the Royals closer, but the offseason signing of Carlos Estevez presents some major competition. It remains to be seen whether a committee approach is utilized or if Erceg or Estevez is shifted to a setup role. Read Past Outlooks

Returns to mound Tuesday
Erceg (foot) collected a hold and tossed a perfect frame in Tuesday's 4-3 win over the Rockies in 11 innings.
ANALYSIS
Erceg departed Friday's 7-3 loss to the Tigers after being struck on the left foot by a comebacker, but X-rays came back negative, and he was ready to go after three days of rest. After Erceg delivered a scoreless eighth inning, Carlos Estevez suffered a blown save in the ninth inning and now has a 10:9 K:BB over 11 frames this season. Erceg has surprisingly managed just five strikeouts in his 8.1 innings, but he's allowed just one run across 10 appearances. Estevez should have some more leash as the Royals' closer, but Erceg would be next in line if manager Matt Quatraro decides to make a change.

Past Fantasy Outlooks
2024
2019
2018
2017
Erceg began his career as an infielder, but converted to pitching a few years ago while he was a member of the Brewers organization. After struggling in the minors as a reliever, Erceg was traded to Oakland last May, where he was given an opportunity to perform at the big league level for the first time. Expectedly, the 28-year-old worked around control issues (14.3% walk rate), but he earned the manager's trust amidst an unsettled Oakland bullpen. Erceg primarily flashed his 98 mph sinker that he complemented with a fastball, changeup, slider and occasional cutter. His change was his best pitch (.190 BA, 38.4% whiff), but he only threw it 22.1% of the time, so it will be interesting to see if he tosses it more often. Erceg's ratios weren't great, but he only permitted one home run across 55 innings, with his 0.16 HR/9 best in the league among qualified relievers. He's a dark horse candidate for save chances, but there could still be growing pains.

Latest Fantasy Rumors

Potential trade piece?
The Athletics may be willing to trade Erceg this summer, per Jim Bowden of The Athletic.
ANALYSIS
Oakland isn't expected to deal dominant closer Mason Miller this summer, but the organization is likely more willing to part with Erceg, who has been working as a setup man. Erceg surrendered two runs during Wednesday's loss to San Diego in his first outing back from a forearm injury, but prior to that he had a 2.86 ERA, 1.00 WHIP and 27:8 K:BB over 22 innings. The 29-year-old still has two more seasons with a pre-arbitration salary, so the Athletics could be patient while evaluating trade options.
