Orioles and Diamondbacks lineups tonight in Arizona (plus notes)

Adley Rutschman is the designated hitter tonight in Arizona, Ryan O’Hearn is playing first base and Ryan Mountcastle is on the bench.

Jordan Westburg is the third baseman and cleanup hitter. Tyler O’Neill is in right field and Heston Kjerstad is in left.

Jackson Holliday is the second baseman.

Charlie Morton has made two starts with the Orioles and allowed nine runs and 13 hits in 8 1/3 innings. He’s struck out 13 batters.

Morton is making his 16^th career start against the Diamondbacks. He’s registered a 4.27 ERA over 86 1/3 innings. Morton has made nine starts at Chase Field and registered a 5.19 ERA in 50 1/3 innings.

Randal Grichuk is 7-for-21 with a double and home run against Morton. Gerald Perdomo is 5-for-9 with two doubles.

Garrett Hampson is 0-for-12.

Right-handed hitters are 8-for-20 with a double and two home runs against Morton this season.

The Orioles haven’t recorded a save through the first 11 games of the season for the first time since 2002 (12).

Right-hander Merrill Kelly has allowed 10 runs and 12 hits in nine innings in his first two starts of the season. He’s also walked seven batters and surrendered three home runs.

The bulk of the damage came against the Yankees, when he allowed nine runs and nine hits in 3 2/3 innings.

Kelly has posted a 4.68 ERA since the start of the 2024 season, an increase from his 3.33 ERA across 2022 and 2023.

Kelly has faced the Orioles only once in his career and it went poorly. He allowed seven runs and eight hits in 2 1/3 innings at Chase Field during his rookie season in 2019. Renato Nuñez, Anthony Santander and Dwight Smith Jr. hit home runs.

The Orioles drafted Kelly in the 37^th round in 2007 out of Desert Mountain High School in Scottsdale, but he attended college.

O'Neill is 3-for-19 with a double and home run against Kelly.

Zach Eflin, who’s celebrating his 31^st birthday today, underwent testing on his right shoulder after experiencing fatigue last night. He allowed one run in six innings for his third quality start but threw only 73 pitches and experienced a dip in velocity.

“Just fatigue,” Eflin told the media last night. “I think it was precautionary. … I’m pretty optimistic.”

Manager Brandon Hyde told the assembled media that reliever Colin Selby is on the taxi squad while a decision on Eflin is pending.

Eflin went on the injured list Aug. 20 with shoulder inflammation and was reinstated Sept. 1.

The Orioles are hosting “Marvel Day” at Camden Yards on Saturday, June 28, when they play the Rays at 4:05 p.m. The first 20,000 fans will receive a Cal Ripken Jr.|Iron Man bobblehead that depicts the Hall of Famer inspired by the popular super hero and iconic Avenger.

Ripken, of course, earned the Iron Man nickname while pursuing and breaking Lou Gehrig’s consecutive-games record.

Fans will be able to enjoy Marvel-themed activations throughout the ballpark that include trivia and various games, and Eutaw Street will be decorated for the occasion.

Ripken passed Gehrig 30 years ago, and the Orioles will continue to honor him with a celebration on Sept. 6 before their 7:05 p.m. game against the Dodgers. Additional details will be announced at a later date.
