Jameson did not factor into the decision Wednesday, tossing four scoreless innings on three hits and zero walks during a 7-3 win over Milwaukee. He struck out four.

Jameson was filling in for Zach Davies, who was recently placed on the 15-day injured list with an oblique injury, and despite looking sharp through four innings, he was pulled after just 54 pitches. The second-year right-hander would seem to be an intriguing streaming option while Davies is out, especially as he stretches out further after a brief stint in the bullpen. He's tentatively scheduled to pitch again versus St. Louis next week.

Helle was optioned to Triple-A Sacramento by the Giants on Wednesday.

Hjelle gets the boot from the major-league roster to make room for Darin Ruf after Ruf's contract was selected by the Giants. The 6-foot-11 right-hander will likely be an up-and-down option for the San Francisco bullpen for the remainder of 2023.

Helsley picked up the save in Wednesday's 7-4 win over the Rockies, striking out two over a perfect ninth inning.

After blowing his first save opportunity of the season, Helsley has been lights out. He hasn't allowed a run in four straight appearances (4.2 innings) and has at least two strikeouts in each of those games.

The Athletics have named Oller their starting pitcher for Thursday's game in Baltimore, Matt Kawahara of the San Francisco Chronicle reports.

Oakland will move to a six-man rotation this week, adding Oller to the mix in order for rookie Shintaro Fujinami to continue making Saturday starts as he transitions from Nippon Professional Baseball to the majors. As a rookie last season, Oller made 19 appearances (14 starts) and struggled to a 6.30 ERA and 1.63 WHIP over 74.1 innings. Since Oller covered five innings and 80 pitches in his most recent relief appearance April 7, he should provide Oakland with a decent amount of length in his first start, but he'll still be tough to trust as a streaming option while he's supported by one of MLB's worst lineups.

Ponce de Leon signed a minor-league contract with the White Sox on Wednesday, Jon Heyman of the New York Post reports.

Ponce de Leon went unsigned all winter after struggling to a 6.52 ERA in 116 innings (26 starts) last season between the Triple-A affiliates of the Mariners, Nationals and Tigers. The 31-year-old right-hander hasn't appeared in a major-league game since 2021 with the Cardinals. He'll head to Triple-A Charlotte.

The Athletics recalled Smith from Triple-A Las Vegas on Wednesday.

Smith will be the replacement in the bullpen for Domingo Acevedo, who was placed on the 15-day injured list with a left lower-back strain. He'll likely operate in the middle innings while he's up with Oakland.

Davidson was bypassed for the start in Wednesday's game against the Nationals, with the Angels instead activating Griffin Canning (groin) from the 15-day injured list to have him take the hill, Sam Blum of The Athletic reports.

Davidson opened the season in the bullpen but had been expected to enter the rotation when the Angels first required a sixth starter this week. However, with Canning progressing quicker than expected from the groin issue that forced him to the IL and then building up to five innings in his lone minor-league rehab start last Thursday, the Angels are opting to keep Davidson in the bullpen for the time being as a multi-inning option. The decision to go with Canning over Davidson for the sixth spot in the rotation became an easier one Monday, when Davidson was needed to cover three frames in relief after Jose Suarez lasted just four innings.

Rockies manager Bud Black said Wednesday that Rolison (shoulder) recently completed a bullpen session without incident, Patrick Lyons of TheDNVR.com reports.

Rolison is currently on the 60-day injured list while recovering from the left shoulder surgery he underwent last June. The southpaw will likely begin to face hitters soon, but he's still probably at least a few weeks away from heading out on a minor-league rehab assignment.

Arizona optioned Vargas to Triple-A Reno on Wednesday.

Vargas has loads of upside as a late-inning relief arm, but he's struggled this season with a 5.79 ERA and 7:4 K:BB over 4.2 innings. He'll try to get on track at Reno before getting another look with the big club.

The Diamondbacks reinstated McGough (personal) from the paternity list Wednesday.

McGough missed Tuesday's loss to the Brewers while welcoming a new member of his family, but the 33-year-old will be available for Wednesday's series finale. Arizona optioned Carlos Vargas to Triple-A Reno in a corresponding move.
