Manager Dave Roberts said Thursday that Treinen (forearm) will begin playing catch within the next few days, Matthew Moreno of DodgerBlue.com reports.

Treinen is pain free and is on the cusp of starting up his throwing program. He'll still have a lengthy ramp-up period, but he may be able to return in mid-June, when he is first eligible to be activated from the 60-day injured list.

Boushley was optioned to Triple-A Round Rock on Thursday.

Boushley has split the season almost exactly evenly between the majors and Round Rock. He threw 2.1 shutout innings Wednesday and has allowed only one earned run across his last 8.1 frames in the majors. Cole Winn was called up in a corresponding move.

The Astros traded Castro to the White Sox on Thursday in exchange for cash, Robert Murray of FanSided.com reports.

Castro signed a minor-league deal with Houston during the offseason and has started the Triple-A season with a 2.29 ERA and 1.20 WHIP across 19.2 innings. The 30-year-old will now join a White Sox organization searching for answers in its bullpen, and his hot start in the minors figures to give him a decent chance at joining the South Siders relatively soon.

Mey struck out two and didn't allow a baserunner in a scoreless inning during Thursday's 7-1 win against the White Sox.

Mey has allowed just one run with an 11:3 K:BB across 7.1 innings since being promoted May 1. The 23-year-old righty has recorded one hold but has mostly pitched in lower-leverage spots so far, though he could work his way into the high-leverage mix if he can continue delivering strong performances. Journeyman Emilio Pagan has taken over the closer role with Alexis Diaz demoted to Triple-A, and if Pagan stumbles, Mey could have an outside shot at seeing save chances later in the season.

Wilson (0-2) took the loss Thursday against Cincinnati, allowing seven runs on 10 hits and one walk with three strikeouts over 5.1 innings.

Wilson made his fifth consecutive appearance at the back end of an injury-depleted White Sox rotation, and he allowed his most hits and runs in an outing this season, including three solo home runs. Since stepping into the rotation, Wilson has posted a 6.86 ERA across 21 innings. He's tentatively scheduled for a start next week against the Mariners.

The Dodgers optioned Feyereisen to Triple-A Oklahoma City on Thursday.

Feyereisen allowed four runs (three earned) on eight hits and a walk over two innings during his brief time with the big club. He's being replaced on the roster by Justin Wrobleski.

Birdsong allowed three earned runs on four hits (two home runs) and two walks while striking out three across three innings of relief in Wednesday's 8-7 loss to the Diamondbacks. He also hit a batter and uncorked a wild pitch.

The 23-year-old entered the game for Jordan Hicks with no outs and two runners on base in the third inning. Birdsong surrendered a three-run homer to the first batter he faced and later gave up a two-run shot in the fourth. The right-hander struggled with his control, throwing 34 of his 65 pitches for strikes while generating nine whiffs. Over his last five appearances, Birdsong has recorded a 3.48 ERA, 1.55 WHIP and a 12:4 K:BB, allowing three home runs across 10.1 innings.

Bivens threw two scoreless innings in Wednesday's 8-7 loss to the Diamondbacks, surrendering two hits and a walk while striking out two.

Bivens turned in a solid performance in Wednesday's high-scoring matchup, allowing just two singles. The right-hander threw a season-high 39 pitches, 24 of which were strikes. The 30-year-old has allowed five earned runs (one home run) in his last five outings, recording a 5.40 ERA, 1.44 WHIP and a 5:2 K:BB across 8.1 innings.

Horton is scheduled to start Friday's game against the White Sox at Wrigley Field, Bruce Levine of 670TheScore.com reports.

After being promoted from Triple-A Iowa last Saturday, Horton made his MLB debut later that day against the Mets, working in bulk relief and striking out five while allowing three runs on four hits and no walks across four innings en route to claiming the win. According to Levine, manager Craig Counsell suggested that the decision to use Horton in relief against the Mets was mainly to spare him from matchups with Francisco Lindor, Juan Soto and Pete Alonso to begin his big-league career, but the top of the White Sox lineup won't provide nearly as tough of a test. Horton should continue to hold down a spot in the Chicago rotation at least until Shota Imanaga (hamstring) is ready to return from the injured list.

Dodgers manager Dave Roberts said that Sauer will start Thursday's game against the Athletics, Fabian Ardaya of The Athletic reports.

Sauer will pick up his first MLB start Thursday, as all 14 of his appearances with the Royals in 2024 as well as his first four with the Dodgers in 2025 had come out of the bullpen. The right-hander made three starts at Triple-A Oklahoma City earlier this season and worked as a bulk reliever or piggyback pitcher in two of his relief outings with Los Angeles, pitching five innings April 29 and four innings May 7. The Dodgers will likely look for Sauer to cover 4-to-6 innings Thursday before turning the game over to the bullpen.
