Reds Add TWO Pitchers After Hunter Greene Injury | Ron Marinaccio & Chase Solesky Claimed; MLB News

Nick Kirby breaks down the latest Reds news.

--------------------------

The Cincinnati Reds continue to search for pitching depth following the trade deadline, adding two right-handed arms on Thursday by claiming Ron Marinaccio from the Pittsburgh Pirates and Chase Solesky from the Tampa Bay Rays.

The club announced that Marinaccio has been added to the major league roster, while Solesky was optioned to Triple-A Louisville. To make room on the 40-man roster, the Reds transferred outfielder Blake Dunn to the 60-day injured list after he recently underwent season-ending internal brace surgery on his elbow.

The move comes at a critical time for Cincinnati. Just one day after placing ace Hunter Greene back on the injured list, the Reds needed additional pitching options as they work through another stretch of injuries. While neither Marinaccio nor Solesky is considered a blockbuster acquisition, both provide much-needed organizational depth for a pitching staff that has been stretched thin.

Marinaccio is the more intriguing addition of the two. The 31-year-old has already established himself as a capable major league reliever over the past several seasons. Entering 2026, he owned a career 3.02 ERA across 125.1 innings while striking out more than 28% of opposing hitters. Although command has occasionally been an issue throughout his career, his swing-and-miss ability made him an effective late-inning bullpen option.

This season, however, has been a different story.

Marinaccio opened the year with the San Diego Padres before being designated for assignment. The Pirates quickly acquired him in exchange for $500,000 in international bonus pool money, but his stay in Pittsburgh lasted barely over a week. Following the Pirates' aggressive trade deadline additions of Luke Weaver, Camilo Doval, Kirby Yates and Lake Bachar, Pittsburgh needed to clear roster space and Marinaccio once again became the odd man out.

Between San Diego and Pittsburgh this season, Marinaccio has posted a 4.99 ERA over 52.1 innings. While he has actually improved his walk rate to a career-best 8.8%, his strikeout percentage has fallen dramatically from nearly 30% in previous seasons to just 18.4% in 2026. That decline has significantly reduced his effectiveness, leading to his second DFA of the season.

The Reds are hoping they can help unlock the version of Marinaccio that made him such a valuable bullpen arm earlier in his career. Because he is out of minor league options, Cincinnati will keep him on the major league roster immediately. If he can rediscover his strikeout stuff, the Reds could potentially have a controllable bullpen piece through the 2029 season.

Solesky represents more of a depth addition than an immediate contributor.

The 28-year-old made his major league debut earlier this season with Tampa Bay, allowing two earned runs over three innings in his lone appearance. Most of his season has been spent at Triple-A Durham, where the results have been less than encouraging. Across 54.1 innings over 23 appearances, Solesky has compiled a 6.79 ERA while posting a modest 20.7% strikeout rate, an 8.8% walk rate and a 41.9% ground-ball rate.

Although those numbers won't jump off the page, Solesky has developed a reputation as a pitcher who consistently throws strikes and competes in the strike zone. FanGraphs recently highlighted him as an honorable mention in the Rays' prospect rankings, noting that while he lacks overpowering stuff, his command makes him a reliable option capable of providing innings when needed.

That profile may be exactly what the Reds are seeking.

With Greene back on the injured list and Julian Aguiar also sidelined, Cincinnati's starting pitching depth has become increasingly thin. Chase Burns, Andrew Abbott, Rhett Lowder and Brady Singer currently make up the active rotation, while Nick Lodolo appears close to returning from the injured list after making a successful rehab start at Triple-A Louisville.

However, Greene's scheduled turn arrives immediately, creating a short-term vacancy. The Reds are expected to use either a bullpen game or call up another starter to bridge the gap until Lodolo returns. Jose Franco was recently optioned and cannot be recalled for another week unless another player lands on the injured list, further limiting Cincinnati's immediate options.

That's where Solesky could become valuable. While he begins his Reds tenure in Louisville, he provides another starting option who could be summoned if the club needs innings over the coming days or weeks.

The timing of these claims reflects Cincinnati's current reality. After remaining relatively quiet at the trade deadline, the organization has instead turned toward waiver claims and internal depth to reinforce its pitching staff. The bullpen has shown significant improvement over the past few weeks, but with Greene sidelined.
