Seattle had high hopes for Smith when it acquired him from Tampa Bay before 2019 in a deal that also involved catcher Mike Zunino, among others. The Mariners seemed right to be bullish on Smith, who was coming off a 3.5-fWAR, 40-steal season at the time. Smith has continued as a stolen base threat since then (he swiped 40 bags in 2019), but the 27-year-old has otherwise struggled. He finished his M’s tenure with 613 plate appearances of .220/.290/.323 hitting and six home runs.
It was also an awful 2020 for Shaw, continuing a downward trend for the once-effective Cleveland reliever. After a woeful two-year stint in Colorado, Shaw joined the Mariners on a big league contract in July, but the deal didn’t work out for either side. The 32-year-old wound up tossing six frames, yielding 12 earned runs on 13 hits and issuing six walks in Seattle.
Yacabonis joined the Mariners in a minor trade with the Padres in August, but he also didn’t establish himself in the M’s bullpen. The 28-year-old gave up one earned runs on two hits and three walks in 2 1/3 innings.
