The Mariners have signed right-handers
Now 28 years old, Guerreri once ranked as one of baseball’s premier pitching prospects. The Rays selected him with the No. 24 overall pick back in 2011, and he was considered to be among the game’s 100 best prospects for the next three years.
As is the case so often with promising young hurlers, however, Guerrieri’s development was halted by Tommy John surgery. Guerrieri underwent that operation midway through the 2013 season and missed all of 2014 as a result. He’s battled other arm troubles since that time and, to this point in his career, has only topped 100 innings in a season on one occasion. He was healthy for the 2019 season, splitting the year between the Majors and Triple-A in a relief role with the Rangers.
Guerrieri tossed 28 1/3 innings with Texas that year and another 9 2/3 with the Blue Jays a year prior, but his results at the MLB level haven’t been impressive so far. In 36 frames, he’s been tagged for a 5.50 ERA with nearly as many walks (22) as strikeouts (27). However, Guerrieri was quite good with the Rangers’ Nashville affiliate in 2019, and he’s displayed elite spin on his curveball in limited big league action.
Chargois, 30, was a second-round pick by the Twins back in 2012 and at one point looked like he could be a future closer in Minnesota. He posted dominant minor league numbers with sizable strikeout rates and an upper-90s heater, but Chargois hasn’t yet found his footing in the big leagues. The Rice University product has just a 4.58 ERA in 76 2/3 MLB frames, though his 3.40 SIERA, 26.3 percent strikeout rate and 9.9 percent walk rate are a bit more encouraging. Chargois pitched with Japan’s Rakuten Eagles last year and struggled to a 5.81 ERA in 26 1/3 innings of work in that tiny sample, but he has a lengthy minor league track record of success — including a 1.90 ERA in 85 1/3 Triple-A frames.
