Megill (elbow) threw about 22 pitches in a live batting practice session Sunday at Citi Field, Abbey Mastracco of the New York Daily News reports.

Megill has now reached another major milestone in his recovery from a right elbow sprain by facing hitters for the first time since landing on the injured list June 17. The right-hander will likely throw another two-inning simulated live BP on Thursday and perhaps another sim game after that before the Mets map out a minor-league rehab assignment for him. The Mets will presumably let Megill get stretched out for a starting role during his assignment, but it's unclear if the big club will actually have a spot available for him in the rotation by the time he's eligible for activation in the middle of August.

Henderson did not factor into the decision in Sunday's win over the Nationals, allowing a run on three hits and two walks over 4.1 innings. He struck out four.

Henderson was impressive overall Sunday, blanking Washington through his first four innings, though the Brewers pulled the right-hander after he gave up a run on back-to-back hits in the fifth. Henderson has been excellent in his brief time in the majors this season, posting a 1.78 ERA with a 0.99 WHIP and 33:8 K:BB across 25.1 innings. He should remain in the rotation for at least a couple more turns with Jacob Misiorowski (lower leg) landing on the IL. Henderson is currently in line to face the Reds on the road in his next outing.

Yamamoto (10-7) earned the win Sunday over the Rays, allowing five hits and no walks over 5.2 scoreless innings. He struck out six.

Yamamoto has been excellent of late, allowing just four runs over 24.2 innings in his last four starts. His ERA is down to 2.51 with a 1.04 WHIP and 139:39 K:BB across 22 starts (122 innings) this season. The 26-year-old Yamamoto will look to keep rolling in his next outing, tentatively scheduled to come next week at home against the AL East-leading Blue Jays.

The Padres reinstated Cortes (elbow) from the 60-day injured list Sunday.

Shortly after being acquired from the Brewers at the trade deadline, Cortes will join the Padres' 26-man active roster after missing about four months due to a flexor strain. The left-hander threw 93 pitches over 5.2 innings during his final rehab outing at Triple-A Nashville on July 24, so he should be able to handle a full starter's workload whenever he makes his Padres debut. The open spot in San Diego's rotation lines up for next weekend versus Boston, but the Padres could have Cortes take the mound during the three-game series in Arizona that begins Monday.

The Padres optioned Vasquez to Triple-A El Paso on Sunday.

The 26-year-old righty took the loss Saturday against St. Louis after giving up five runs over four innings, and he'll now be the odd man out of the rotation with San Diego activating trade-deadline pickup Nestor Cortes (elbow) from the 60-day injured list in a corresponding move. Vasquez has been a decent back-end arm for San Diego this season with a 3.93 ERA, though his 1.39 WHIP and 55:48 K:BB over 107.2 innings have resulted in limited fantasy utility. He seems likely to be back with the Padres before the end of the season, whether it be as a starter or reliever.

Misiorowski (tibia) said he expects to miss two starts before returning to the active roster when first eligible Aug. 15, Curt Hogg of the Milwaukee Journal Sentinel reports.

Misiorowski's placement on the IL on Sunday came as a surprise after the Brewers had previously confirmed him as their starter for the contest, but the rookie right-hander acknowledged that he hadn't recovered as well as expected after being struck in the shin by a line drive in his previous start Monday. Assuming that the 23-year-old is able to continue throwing while he's on the shelf, his goal of returning in the minimum 15 days seems realistic. Milwaukee called up Logan Henderson to start Sunday, and he should be in line for another turn through the rotation next weekend versus the Mets.

The Brewers recalled Henderson from Triple-A Nashville, and he's slated to start Sunday's game against the Nationals, Curt Hogg of the Milwaukee Journal Sentinel reports.

Henderson will take over the rotation spot of Jacob Misiorowski, who was unexpectedly placed on the 15-day injured list Sunday due to a left tibia contusion. Though Misiorowski has drawn far more buzz, Henderson was arguably just as impressive over his first four MLB starts, logging a 1.71 ERA, 0.95 WHIP and 29:6 K:BB in 21 innings. Since returning to Nashville, Henderson's ratios haven't been quite as eye-popping (4.34 ERA, 1.20 WHIP, 47:13 K:BB in 47.2 innings). He should be in line for at least two turns through the rotation, and maybe more if Misiorowski isn't ready to return from the IL when first eligible.

The Brewers placed Misiorowski on the 15-day injured list Sunday due to a left tibia contusion.

Misiorowski took a Seiya Suzuki comebacker off his shin in the first inning Monday, and even though he remained in that game and had been confirmed to start Sunday's series finale against Washington, the star rookie evidently didn't bounce back from the injury as the Brewers had hoped. He'll be sidelined through at least mid-August. Right-hander Logan Henderson was recalled from Triple-A Nashville in a corresponding move and will replace Misiorowski in the rotation Sunday.

Vasquez (3-5) was charged with the loss against the Cardinals on Saturday after surrendering five runs on eight hits and no walks across four-plus innings. He struck out three.

The right-hander was staked a 4-0 lead after three innings, but he allowed five runs across the fourth and fifth frames before being pulled. The performance ended a run of four straight starts allowing two runs or fewer, though Vasquez hasn't lasted five innings since July 4 and is without a victory in his past 13 outings. The right-hander's next start lines up for next weekend versus Boston, though he could be replaced in the rotation by Nestor Cortes (elbow).

McGreevy (3-2) earned the win Saturday in San Diego after giving up four runs on seven hits and one walk over six innings. He struck out four.

The right-hander surrendered runs in each of the first three frames to put St. Louis in a 4-0 hole, but he bounced back with three scoreless innings while the Cardinals offense rallied for six runs across the fifth and sixth innings. It was the third straight turn through the rotation for McGreevy, who should continue to get an extended look with the Cardinals down the stretch. In seven appearances (six starts) this season, he has a 5.08 ERA, 1.23 WHIP and 23:6 K:BB over 39 innings.
