The D-backs are bolstering their starting pitching rotation with the addition of veteran right-hander Zack Littell, who was designated for assignment by the Nationals. This move comes as a strategic response to the team's current pitching challenges and the need for reliable arms. With key rotation options like Merrill Kelly, Zac Gallen, and Corbin Burnes dealing with injuries, the D-backs are seeking to fill the void and ensure a stable lineup.
Littell, a 30-year-old pitcher, has a diverse pitching repertoire, including a four-seam fastball, sinker, slider, splitter, and sweeper. His average four-seam fastball speed of 91.7 mph is not particularly high, but he relies on his five-pitch mix to keep batters off balance. Littell's slider has been particularly effective, limiting batters to a .227 average in 2026. However, his four-seam fastball has been less successful, with a .306 average and .639 slugging percentage, resulting in 25 home runs allowed across 112 1/3 innings this season.
Despite his struggles with the four-seam fastball, Littell has been a reliable innings eater for the Nationals, working at least five innings in 15 of his 23 appearances. He has also shown the ability to hold right-handed batters to a .249 average and .690 OPS, with 18 of the 25 homers he's allowed coming against lefties. The D-backs' strong defensive unit, ranked second in the league by FanGraphs' outs above average measurement, could further enhance Littell's performance and help him improve his contact-based arsenal.
In my opinion, the D-backs' decision to acquire Littell is a strategic move that addresses their immediate pitching needs. With key rotation options sidelined, adding a reliable arm like Littell provides stability and depth to the starting pitching rotation. His ability to eat innings and his diverse pitching repertoire make him a valuable asset, especially with the team's strong defensive unit. As the D-backs continue to navigate the challenges of the Arizona summer, Littell's addition could be a crucial step in their pursuit of a successful season.
