Manager Dave Roberts said Treinen (shoulder) threw a "normal" bullpen session Wednesday and could soon face live batters, Fabian Ardaya of The Athletic reports.

Treinen was activated from the injured list Sept. 2 but returned to the shelf with shoulder tightness after only two outings, yet he's quickly been able to resume mound work. The right-hander will be eligible to return from the IL late next week and may not require a rehab assignment given the expected brevity of his absence.

Jackson was optioned to Triple-A Oklahoma City on Wednesday, Bill Plunkett of The Orange County Register reports.

Jackson was called up by the Dodgers over the weekend and delivered two scoreless frames Sunday against the Padres. It's was the 26-year-old's season debut for Los Angeles despite two previous stints in the majors this year.

Trivino has made three relief appearances for the Yankees since experiencing back spasms earlier this month, covering 1.2 innings in those outings while striking out one and allowing one earned run on three hits and one walk.

Trivino apparently picked up the injury coming out of his Sept. 4 appearance and didn't pitch for six days before he was used out of the bullpen last weekend. The Yankees haven't indicated that Trivino has experienced any setbacks since returning to action, so he'll likely continue to serve in a middle-relief or setup role for the club moving forward.

Pilkington is scheduled to start the second game of Saturday's doubleheader with the Twins, Ryan Lewis of the Akron Beacon Journal reports.

He'll be getting his second start of the week after he worked five innings while giving up four earned runs on three hits and three walks in a no-decision against the Angels on Monday. Pilkington is likely to head to the bullpen or to Triple-A Columbus following Saturday's outing, as Aaron Civale (forearm) looks to be trending toward a return from the 15-day injured list next week and would presumably take back his rotation spot from the rookie left-hander.

Chapman (leg) will join the Yankees in Milwaukee on Friday and will be activated for the series opener against the Brewers, Bryan Hoch of MLB.com reports.

The veteran left-hander appeared in two minor-league games during his rehab assignment earlier this week and is poised to rejoin the big club Friday after being sidelined more than three weeks by a leg infection. Clay Holmes is back in the closer role since he returned from the injured list in late August, and Chapman could fill a setup role upon his activation.

Alzolay (lat) is expected to be reinstated from the 60-day injured list this weekend, Taylor McGregor of Marquee Sports Network reports.

Alzolay has been on the injured list all season due to a lat strain, but he began a rehab assignment Aug. 22. Over five minor-league outings, he's posted a 5.84 ERA and 1.54 WHIP in 12.1 innings. The 27-year-old hasn't tossed more than three innings in any of those appearances and will pitch out of the Cubs' bullpen once he's officially activated.

The Diamondbacks will promote Jameson from Triple-A Reno to start Thursday's game against the Dodgers, Nick Piecoro of The Arizona Republic reports.

The 25-year-old right-hander becomes the latest upper-level pitching prospect to get a trial in the big-league rotation after Tommy Henry and Ryne Nelson both received looks in the second half of the season. Henry has since been moved back to Reno, but Jameson will now receive a look as Arizona temporarily expands to a six-man rotation in a busy portion of the schedule. Though Jameson's numbers at Reno aren't impressive on the surface (6.95 ERA, 1.95 WHIP and 109:42 K:BB over 114 innings), he pitched primarily in hitter-friendly parks in the Pacific Coast League. He's at least done well to keep the free passes in check since the All-Star break (6.4 percent walk rate in 54.1 innings).

The Athletics outrighted Tapia to Triple-A Las Vegas on Wednesday.

He'll stay in the Oakland organization after he cleared waivers following his removal from the 40-man roster. Prior to being designated for assignment, Tapia made 11 appearances out of the big-league bullpen and turned in an 8.47 ERA over 17 innings.

Scott was claimed off waivers by the Phillies on Wednesday.

Scott was designated for assignment by the Padres on Sunday after being reinstated from the injured list, but he'll land a spot on Philadelphia's 40-man roster. The right-hander posted a 3.76 ERA and 1.29 WHIP in 40.2 innings at Triple-A El Paso to begin the year and will report to Triple-A Lehigh Valley after being claimed off waivers.

Hildenberger (undisclosed) began a rehab assignment at Single-A San Jose last week and allowed two earned runs on two hits while striking out one in a one-inning appearance Sunday.

Hildenberger has resided on Double-A Richmond's 60-day injured list all season with an unspecified injury. He initially began a rehab assignment in early August in the rookie-level Arizona Complex League, but he was shut down for a month before starting up his assignment at Single-A. He could rejoin the Richmond bullpen over the final couple weeks of the season.
