The Orioles optioned reliever Joey Krehbiel to Triple-A Norfolk after last night’s game and activated reliever Jacob Webb, who was a waiver claim Monday from the Angels.

Krehbiel made two appearances with the Orioles and retired all five batters he faced.

Webb, who’s wearing No. 66, was designated for assignment Saturday after posting a 3.98 ERA and 1.358 WHIP in 29 relief appearances. He walked 20 batters and struck out 34 in 31 2/3 innings.

The Braves drafted Webb in the 18th round in 2014 out of Tabor College in Kansas. Prior to this season, he had appeared in 78 games over three seasons and had a 2.47 ERA and 1.304 WHIP in 76 2/3 innings.

Reliever Reed Garrett wore No. 66 earlier this season. It previously belonged to Tanner Scott and T.J. McFarland.

No word yet on the status of center fielder Cedric Mullins, who’s played in three injury rehab games with Double-A Bowie. He had two hits last night and is nearing a return.

Adam Frazier is expected to be in the lineup tonight, his first start since jamming his right thumb on the Rogers Centre turf in Toronto on Thursday. He entered last night’s game after Ramón Urías exited with a sore left heel.

Urías is likely day-to-day, but we’ll find out more later.

Jack Flaherty is making his second start with the Orioles after holding the Blue Jays to one run and striking out eight batters over six innings at Rogers Centre.

Flaherty’s only career start against Houston came on July 26, 2019 in St. Louis, when he allowed two runs and three hits with nine strikeouts in six innings.

Flaherty has registered a 2.78 ERA since July, but left-handed hitters are slugging .603 against him during that span.

The Orioles are expected to face plenty of right-handers on their West Coast trip, and they also get Cristian Javier tonight.

Javier is 7-2 with a 4.39 ERA and 1.207 WHIP in 21 starts. Right-handers are hitting .178/.251/.335 against Javier and left-handers are batting .278/.345/.496.

Javier has made four career appearances against the Orioles – only one start – and allowed two runs with 17 strikeouts in 12 2/3 innings.

Frazier is 2-for-5 with a double and walk against Javier.

Opponents are batting .302 against Javier’s sweeper in his last 10 starts, per STATS, compared to a .141 average against it previously this season.

The Astros are 22-11 against the Orioles and 13-5 at Camden Yards since the beginning of 2017.
