Miller (elbow) said he will throw a simulated game Friday in Houston and will operate on a six-day routine moving forward, Daniel Kramer of MLB.com reports.

EDGE Analysis

The sim game will be up-and-down for two innings. Miller believes if it goes well, he will avoid a rehab assignment and could subsequently return to the Mariners' rotation. The righty is coming back from right elbow inflammation that he has dealt with throughout the season, with the injury ultimately landing him on the injured list May 12.

Miller (elbow) played catch in the outfield prior to Wednesday's game against the White Sox, MLB.com reports.

EDGE Analysis

Miller continues to recover from right elbow inflammation, which he'd been dealing with throughout the season before needing to go on the injured list May 12. It's unclear whether the right-hander will require a brief minor-league rehab assignment before rejoining Seattle's rotation, but he appears to have a chance of returning before the end of May at this point. Miller's throwing progression will remain worth monitoring, as the Mariners have yet to offer a concrete timetable for the 26-year-old's return to action.

The Mariners placed Miller on the 15-day injured list Wednesday due to right elbow inflammation.

EDGE Analysis

Miller wasn't known to be nursing an elbow injury, but this issue may explain in part why he labored during his latest start against the Blue Jays on Sunday, when he served up a season-high seven runs on eight hits and two walks over five innings. According to Shannon Drayer of SeattleSports.com, general manager Justin Hollander said that Miller received a cortisone shot Tuesday to treat the injury, and the Mariners are optimistic that he'll be ready to return from the IL when first eligible May 27. Seattle called up lefty Jhonathan Diaz from Triple-A Tacoma in a corresponding move, and he could take Miller's spot in the rotation this weekend in San Diego if he's not needed in relief in Wednesday's game against the Yankees.

Miller (2-4) allowed seven runs on eight hits and two walks while striking out three over five-plus innings to take the loss versus the Blue Jays on Sunday.

EDGE Analysis

Miller struggled throughout the 92-pitch outing, though the game didn't get out of hand until he allowed a three-run home run to George Springer in the fifth inning. The seven runs allowed were a season high for Miller, who has also given up four runs on three other occasions. He's now at a 5.22 ERA, 1.54 WHIP and 35:21 K:BB through 39.2 innings over eight starts, and he's yet to complete six innings in any of them. He's tentatively projected to make his next start on the road in San Diego.

Miller allowed four runs on seven hits and struck out one without walking a batter in a no-decision versus the Athletics on Monday.

EDGE Analysis

Miller battled a back issue in his previous start, but he didn't appear to be limited Monday, throwing 63 of 94 pitches for strikes. While he found the zone just fine, he wasn't fooling the Athletics' hitters much. This was Miller's shortest start of the season by innings pitched, and it's the third time he's allowed at least four runs. He's at a mediocre 4.15 ERA, 1.47 WHIP and 32:19 K:BB over 34.2 innings across seven starts, but this was his first start of the season in which he avoided walking a batter. Miller is projected for a home start versus the Blue Jays this weekend.

Miller revealed after Tuesday's start versus the Angels that his back "locked up" on him pregame, Daniel Kramer of MLB.com reports.

EDGE Analysis

Miller did not sit down in between innings to avoid making the back issue worse. He successfully navigated through five scoreless frames in the outing, although he issued a season-high five walks. Miller also noted that he dealt with some arm soreness earlier this month, saying that it's been "one thing after another that hasn't been major, but just been nagging." The right-hander is scheduled to face the Athletics on Monday and it does not appear at this point that he's in any danger of missing that start.

Miller (2-3) picked up the win in Tuesday's 5-3 victory over the Angels, giving up two hits and five walks over five scoreless innings. He struck out six.

EDGE Analysis

The 26-year-old right-hander continues to fight his control, even though he was able to avoid any damage from his walks Tuesday. The five free passes were a season high for Miller, and after posting a 6.4 percent walk rate in 2024, he's seen that mark balloon to 14.7 percent through six starts and 30.2 innings this year. His 3.52 ERA is still decent on the surface, but his 1.43 WHIP and 4.44 xFIP are red flags that his luck could run out soon. Miller will try to tighten things up in his next outing, which is scheduled to come on the road early next week against the A's.

Miler (1-3) took the loss against Boston on Tuesday. He allowed four runs on five hits and four walks while striking out four across 4.2 innings.

EDGE Analysis

Miller had particular trouble facing off against Alex Bregman, with the third baseman responsible for driving in three of the four runs Miller gave up in Tuesday's contest. Miller wasn't able to make it out of the fifth inning despite tossing 100 pitches (59 strikes), and through five starts he's up to a 4.21 ERA and 1.44 WHIP over 25.2 innings. He's in line to make his next start against the Marlins at home this weekend.

Miller (1-2) earned the win against the Reds on Wednesday, allowing three hits and two walks while striking out eight across five scoreless innings.

EDGE Analysis

Miller came out firing Wednesday, punching out six of the first eight batters faced before striking out two more in the fifth frame. It was another sharp outing for Miller, who has begun the season with a 3.43 ERA, 1.33 WHIP and 21:10 K:BB across 21 innings. He'll look to make it two wins in a row in his next start, tentatively slated for next week at Fenway Park against the Red Sox.

Miller didn't factor into the decision Friday against the Rangers after allowing one run on two hits and three walks in five innings. He struck out five.

EDGE Analysis

Miller arguably pitched well enough to deserve a win Friday, giving up just a lone run, but the Mariners lost the lead in the sixth inning and didn't regain it until the eighth. While the right-hander holds a rocky 4.50 ERA, 1.44 WHIP and 13:6 K:BB over 16 frames, he's lasted at least five innings in each of his three starts. Miller will encounter a tough setup in his next scheduled start, which is slated for the middle of next week at hitter-friendly Great American Ball Park against the Reds.
