Seattle Mariners starting pitcher George Kirby threw six innings of one-run ball but did not factor into the decision in Wednesday's 2-1 walk-off victory over the Astros. Kirby scattered six hits and did not walk a batter while striking out eight. It was a much-needed strong outing after allowing five earned runs in each of his last two starts. The righty's record stands at 4-5 on the season with a 4.08 ERA (3.33 FIP), 1.02 WHIP, and a 21.1% K-BB%. The former first-round draft pick gets another chance to keep things heading in the right direction in a favorable matchup against the A's on Tuesday, a team that has the second-most strikeouts and third-lowest team batting average in all of baseball.

Tampa Bay Rays second baseman Brandon Lowe will retreat to the bench on Thursday against the visiting Oakland Athletics with a left-handed pitcher on the mound. Outfielder Richie Palacios and infielder Jonathan Aranda are also taking the day off. With Lowe sitting, Amed Rosario will start at second base and bat seventh against A's lefty Hogan Harris. Harold Ramirez is serving as the designated hitter and is batting in the two-hole, with Jonny DeLuca in right field and batting fifth. Since returning from the injured list on May 20, Lowe has not been able to get comfortable at the plate, going 4-for-23 with a double, two triples, four RBI and six strikeouts in 27 plate appearances over eight games. Lowe still has appealing pop at the second base position, but he has yet to hit in 2024 and is a big injury risk.

Tampa Bay Rays right-hander Shawn Armstrong is listed as the starter for the team's game on Thursday against the visiting Oakland Athletics. Armstrong is serving as the opener for this contest for Tampa, with left-hander Tyler Alexander expected to take over as the bulk reliever after Armstrong goes an inning or two. The 33-year-old has performed well as the opener four other times for the Rays this year, but that doesn't mean he's a viable streamer for fantasy purposes. Armstrong is currently 1-1 on the year with a 3.91 ERA, a 1.22 WHIP, one save, 30 strikeouts and nine walks in 25 1/3 innings over 20 appearances (four starts). Alexander has a good matchup once he enters the game, but the 29-year-old southpaw hasn't been nearly as effective as Armstrong has been this year.

Colorado Rockies outfielder Brenton Doyle went 2-for-2 with two walks in Wednesday's 7-4 win over the Guardians. Doyle also scored once, but it could have been an even more productive day had he not been caught stealing once and picked off once. The former fourth-round draft pick's batting average hit a high-water mark of .330 on April 25, but has seen it drop to .271 since then. He's been able to get on base via the walk, however, with 14 walks in his last 16 games, which has afforded him opportunities to steal bases. The speedster has ten stolen bases over the last 17 games after stealing just four over the first 36 games. He's also remained fantasy-relevant due to his ability to score, having crossed the plate 36 times so far this season.

The Oakland Athletics recalled left-hander Hogan Harris from Triple-A Las Vegas on Thursday and placed left-hander Kyle Muller (shoulder) on the 15-day injured list (retroactive to May 27) with left-shoulder tendonitis in a corresponding move. Harris is making the spot start for the A's on Thursday in the series finale against the Tampa Bay Rays. The 27-year-old southpaw will be making his first start of the year for the A's and only his seventh career big-league start after making six starts in his rookie year in 2023. In his two relief outings for the A's in 2024, Harris has allowed four earned runs on eight hits while walking three and fanning eight in 8 2/3 relief innings. He wasn't particularly effective as a starter in Vegas and has a 6.78 career ERA in the majors in 71 2/3 innings, so Harris is a streaming option to avoid on Thursday.
