Spencer Arrighetti, Blake Snell, and Zebby Matthews are among the notable pitchers facing injury challenges this season, causing concern for fantasy baseball managers. Arrighetti, a promising talent with a 3.04 ERA last season, is recovering from a broken thumb and is expected to return around the All-Star break in July. Snell, who has a history of injuries, is dealing with shoulder inflammation and might not be back until mid-July, making him a candidate for stashing on fantasy rosters. Finally, Matthews, who started strong this season, is sidelined with a moderate shoulder strain and has an uncertain return timeline, making him less favorable for keeper leagues.

The Minnesota Twins have recalled right-hander Simeon Woods Richardson to start against the Texas Rangers, necessitated by injuries to starters Pablo López and Zebby Matthews. Woods Richardson began the season with a 5.02 ERA over eight appearances and was sent down to Triple-A after struggling. López, the Twins' ace, is sidelined for two to three months with a Grade 2 shoulder strain, while Matthews is expected to return sooner after a moderate shoulder strain. This puts pressure on the Twins' pitching staff, which has been performing well, ranking ninth in MLB starting pitching with a 3.64 ERA.

The Minnesota Twins are facing mounting challenges with their pitching rotation as Zebby Matthews has been placed on the 15-day injured list due to a shoulder strain, following a similar injury to Pablo López, who will miss two months. Matthews felt discomfort during a bullpen session and struggled in two starts, leading to an MRI that confirmed the strain. Manager Rocco Baldelli expressed concerns over Matthews' health and the team's depth, with Simeon Woods Richardson expected to take his place in the rotation.

Woods Richardson's recent performance in the minors has been shaky, which raises questions about the team's ability to maintain effectiveness on the mound. The Twins are under pressure to ensure their remaining starters, including Joe Ryan and Chris Paddack, perform at a high level to avoid a repeat of last season's struggles caused by injuries.

As the MLB season progresses, streaming options on the waiver wire become essential for fantasy baseball managers looking to bolster their rotation. Here are ten pitchers, all rostered in under 80% of CBS Sports leagues, to consider for Week 12 (June 9-15). These pitchers could provide significant value, especially in two-start scenarios.

Eury Pérez returns from Tommy John surgery, facing the Pirates and Nationals in his first week back, presenting solid matchup potential. Jack Leiter, contingent upon the Rangers' rotation adjustments, offers a strong ERA but faces uncertainty in his second start.

Griffin Canning has been effective lately, although his high walk rate raises concerns. Zebby Matthews is gaining trust within the Twins' rotation and faces manageable lineups. Meanwhile, Hayden Birdsong’s performances suggest he could thrive at Coors Field against a struggling Rockies offense.

Jeffrey Springs and Luis Ortiz also make the list, each with favorable matchups that could lead to quality starts. Mitch Keller's recent struggles somewhat mitigate his streaming appeal, but he remains a candidate. Finally, Clarke Schmidt benefits from two starts, one against a weak Royals lineup. Each of these pitchers presents varying levels of risk and upside for managers looking to maximize their pitching stats this week.

The Minnesota Twins are gearing up for a challenging stretch with ace Pablo López sidelined for months due to injury. Manager Rocco Baldelli is looking to young pitchers David Festa, Zebby Matthews, and Simeon Woods Richardson to step up and provide valuable innings in the starting rotation. Historically, these young arms have struggled to pitch beyond five innings consistently, but Baldelli emphasizes the need for them to gain depth in their outings, which will subsequently relieve the overworked bullpen. The aim is to keep the starters throwing into the sixth and seventh innings to help maintain team stamina and performance.

Meanwhile, the Twins recently completed a four-game series against the Athletics at Sutter Health Park, where they expressed relief at leaving behind what has been described as a brutal playing surface that has caused discomfort for players like Carlos Correa and Ty France. Correa notably missed games due to back pain attributed to the hard batter’s box, while Joe Ryan raised concerns about the mound’s quality likely affecting pitchers' health. The organization is now focused on ensuring their young starters can contribute effectively and remain healthy.
