The St. Louis Cardinals have reportedly added left-handed pitcher Josh Fleming, giving the organization another experienced arm as it continues through the 2026 season. The move came during the Cardinals’ series with the Cincinnati Reds and represents a low-risk addition to the club’s pitching depth.
Fleming is a 30-year-old left-hander with six seasons of major-league experience. He originally reached the majors with the Tampa Bay Rays in 2020 and has also pitched for the Pittsburgh Pirates and Toronto Blue Jays. His career has included both starting and relief work, making him particularly useful as a potential swingman or multi-inning option.
Fleming’s 2026 journey
Fleming’s 2026 season has already included several organizational changes. He began the year with Toronto after signing a minor-league contract with the Blue Jays in February. Toronto selected his contract on April 6, giving him a brief return to the majors. He appeared in relief against the Los Angeles Dodgers, working three innings, before being designated for assignment the following day. He subsequently returned to the minors.
At Triple-A Buffalo, Fleming produced a 3.08 ERA over 64.1 innings, a performance that made him an intriguing depth option despite his limited MLB opportunity with Toronto. His pitch mix includes a sinker, changeup, sweeper and cutter.
Toronto ultimately released Fleming in July. He then joined the Chicago Cubs, signing a minor-league deal and reporting to Triple-A Iowa. However, Iowa released him on August 17, according to Minor League Baseball’s transaction log.
What Fleming brings to St. Louis
The attraction for St. Louis is his versatility and experience. Fleming has spent much of his career working in different roles rather than being locked into a traditional starting or relief job. That gives a team the ability to use him for multiple innings, cover games when a starter exits early or provide additional left-handed depth.
His most successful stretch came early in his career with Tampa Bay. As a rookie in the shortened 2020 season, Fleming went 5-0 with a 2.78 ERA, establishing himself as a pitcher capable of handling significant innings.
He has subsequently dealt with the normal roster movement associated with a veteran trying to remain in the majors, spending time with multiple organizations and frequently working in Triple-A. His 2026 numbers at Buffalo nevertheless demonstrated that he can still be effective at the upper-minor-league level.
Why the signing makes sense
For the Cardinals, this is less about making a splash and more about strengthening organizational depth.
A minor-league addition allows St. Louis to bring in a pitcher with considerable MLB experience without committing a significant amount of money or a major-league roster spot. If Fleming performs well, the Cardinals could potentially turn to him when they need an additional lefty or a pitcher capable of covering several innings.
There is also value in having a veteran who has already experienced different roles. Fleming has started games, worked in relief and handled multi-inning assignments during his professional career.
Fleming’s MLB résumé
Through his major-league career, Fleming has compiled a 20-14 record with a 4.86 ERA and 162 strikeouts. He has appeared in more than 80 MLB games and has made starts as well as relief appearances.
His career path also shows why he remains an attractive depth candidate. After establishing himself with Tampa Bay, he moved through several organizations, including Pittsburgh and Seattle, before landing with Toronto in 2026. Minor-league opportunities have kept him active even when he hasn’t held a permanent MLB roster spot.
Bottom line
The Cardinals’ reported addition of Fleming is a depth move rather than a headline-grabbing acquisition, but it could prove useful if the club needs another experienced left-handed pitcher down the stretch.
Fleming’s 3.08 ERA in 64.1 Triple-A innings at Buffalo is the most encouraging recent indicator. Combined with his six years of MLB experience and ability to work in multiple roles, it gives St. Louis a potentially useful option without requiring a major investment.
One important update: the Heavy article’s headline concerns St. Louis adding Fleming, but his 2026 transaction history is unusually fluid. Minor League Baseball’s current transaction record shows that he was released by Iowa on August 17, so his status should be treated as a recent roster-development story rather than assuming he remains with his previous organization.
