Weaver will start Tuesday's game against the Athletics, Daniel Kramer of MLB.com reports.

EDGE Analysis

George Kirby was originally slated to start Tuesday's contest but was scratched due to an illness, allowing Weaver to make his first start as a Mariner. Weaver accumulated a 6.87 ERA and 1.64 WHIP through 97 innings as a starter with Cincinnati, but he's been much more effective since signing with Seattle last week.

Weaver, who signed a major-league deal with the Mariners on Tuesday, will work in a long-relief role out of the bullpen, Ryan Divish of The Seattle Times reports.

EDGE Analysis

With Emerson Hancock (shoulder) done for the year, Weaver would likely be the next man up if the Mariners need a spot starter, but there aren't any plans to go to a six-man rotation. He had a 5.57 ERA, 1.67 WHIP and 21 strikeouts in 21 innings over his last five outings for the Reds before they released him last week.

Weaver was signed by the Mariners to a major-league contract and was added to the active roster Tuesday.

EDGE Analysis

Weaver was released by the Reds after he allowed four runs in two of his last three starts. Following the All-Star break, his ERA rose as high as 7.22 and currently sits at 6.87. The signing comes the same day Emerson Hancock was moved to the 60-day injured list with a right shoulder strain. The Mariners had planned on operating with a six-man rotation prior to Hancock's injury, so Weaver could slot into that spot or work as a long man out of the bullpen.

The Reds released Weaver on Friday, Charlie Goldsmith of The Cincinnati Enquirer reports.

EDGE Analysis

Weaver was designated for assignment Wednesday after putting up a 6.87 ERA and 1.64 WHIP through 97 innings across 21 starts, and he'll now look to secure a spot with another organization. Weaver's poor MLB track record might keep him from contributing in the majors, but he figures to have a decent shot at landing a minor-league deal elsewhere.

Weaver yielded four runs on six hits and a walk over 3.2 innings during a Game 2 win in Sunday's doubleheader against Pittsburgh. He struck out seven and did not factor in the decision.

EDGE Analysis

The Pirates greeted Weaver with two runs in the first inning and he never really settled in Sunday. He's failed to complete at least five innings in six of his last seven starts, including his last three. During that stretch, he's produced a 7.24 ERA, driving his season number up to 6.87 through 97 frames. Weaver's next outing is projected to be at home against Toronto.

Weaver did not factor into the decision Tuesday, allowing a run on five hits and a walk over 4.1 innings in a 3-2 loss to the Marlins. He struck out six.

EDGE Analysis

Weaver wasn't bad Tuesday, though he was only able to make it through 4.1 innings on 89 pitches. The 29-year-old right-hander's made it through five innings just twice in his last 12 starts -- he's posted an ugly 7.97 ERA over that span (49.2 innings). Weaver is now 2-4 this season with a 6.75 ERA, 1.63 WHIP and 78:33 K:BB across 20 starts (93.1 innings) this season. He's currently lined up for a road matchup with the Pirates in his next outing.

Weaver (2-4) took the loss against the Cubs on Thursday, allowing four runs on four hits and four walks while striking out five batters over three-plus innings.

EDGE Analysis

Weaver's wildness was largely to blame for his poor outing, as he threw only 46 of 83 pitches for a strike and tied a season high with four free passes. Those four walks came in a span of five batters in the third frame, with the latter two each forcing in a run. Weaver was allowed to close out that inning but was given the hook after allowing a single to the first batter he faced in the fourth. The right-hander was solid in a quality start against the Dodgers his last time out, but he's been otherwise awful of late -- Thursday was the fourth time in his last five outings that he's given up at least three earned runs while going four of fewer frames. Weaver's season ERA now sits at an ugly 6.98, and it's fair to wonder if he'll be long for the rotation with Hunter Greene (hip) and Nick Lodolo (lower leg) both expected to return later this month.

Weaver (2-3) allowed three runs (one earned) on two hits and two walks while striking out two over six innings to take the loss Saturday versus the Dodgers.

EDGE Analysis

Weaver turned in a fine performance, but a pair of Max Muncy home runs sent him to his first loss since May 1. Weaver earned his second quality start of the year with this effort. The right-hander is now at a 6.80 ERA, 1.60 WHIP and 67:28 K:BB through 86 innings over 18 starts. He's projected for a road start versus the Cubs next week, but his poor numbers on the year could cost him his spot in the rotation if the Reds add starting pitching before Tuesday's trade deadline.

Weaver did not factor into the decision Sunday, allowing three runs on eight hits and two walks over four innings against the Diamondbacks. He struck out one.

EDGE Analysis

After being forced out of his last start after being struck in the left elbow by a comebacker, Weaver made his usual turn in the rotation Sunday and threw 79 pitches. Weaver held the Diamondbacks scoreless through his first four innings of work but gave up four consecutive hits, including a two-run homer to Corbin Carroll, to start the fifth and was immediately pulled from the contest. Sunday's outing marked Weaver's fourth straight start surrendering a home run while lasting fewer than five frames for the seventh time in his last nine starts. Over that latter stretch, Weaver owns an ugly 9.41 ERA and a 23:17 K:BB through 36.1 innings.

Weaver (elbow) will start Sunday's game against the Diamondbacks in Cincinnati.

EDGE Analysis

Weaver's most recent start Tuesday against the Giants ended early after he was stuck in the left elbow by a comebacker, but he was fortunate to avoid any structural damage to his arm. According to Charlie Goldsmith of The Cincinnati Enquirer, manager David Bell said Weaver did experience some bruising and swelling, but it apparently won't prevent the right-hander from making his usual turn through the rotation on his normal four days' rest. Weaver carries a 2-2 record, 7.22 ERA and 1.63 WHIP into Sunday's contest and won't make for a comfortable streaming option.
