9:40pm: Urena’s battling lower back tightness, Wells Dusenbery of the Sun Sentinel tweets.
7:10pm: Right-hander Jose Urena, who had been lined up to start tomorrow’s game, will be placed on the injured list, tweets Joe Frisaro of MLB.com. It’s not yet known what type of injury Urena is dealing with. The team has yet to formally announce either move.
5:16pm: The Marlins will promote right-handed pitching prospect Jordan Yamamoto to make his Major League debut tomorrow, Yamamoto himself confirmed to FishStripes.com’s Ely Sussman (Twitter link). He’s already on the 40-man roster, so the team will only need to make a 25-man roster move to accommodate his arrival.
Yamamoto, 23, is one of the four players Miami received in the 2017-18 offseason blockbuster that sent future MVP Christian Yelich to the Brewers. Being a part of such a high-profile trade will always lead to some unfair expectations, but to this point in his tenure with the Miami organization, Yamamoto has looked like a rather intriguing pitching prospect. In 68 2/3 innings split primarily between Class-A Advanced and Double-A last year, the Hawaiian-born righty notched a 1.83 ERA with a tremendous 85-to-14 K/BB ratio (11.1 K/9, 1.8 BB/9). He also pitched to a 2.08 ERA in 26 inning during the Arizona Fall League.
So far in 2019, he’s turned in a strong 3.58 ERA with 8.8 K/9, 3.4 BB/9, 0.96 HR/9 and a 45.6 percent ground-ball rate through 65 1/3 innings of work. In all, he has a 3.28 ERA with better than a strikeout per inning and roughly average ground-ball tendencies in 82 1/3 innings of Double-A ball.
MLB.com ranks Yamamoto as the Marlins’ No. 17 prospect, calling his curveball a “consistent plus pitch” and adding that high spin rate on his fastball helps to offset the pitch’s fairly pedestrian velocity. Fangraphs tabbed him 23rd among Miami farmhands to open the season, noting that there’s a wide variety of outcomes on Yamamoto — all of which are somewhat dependent on his secondary offerings. He’s a potential back-of-the-rotation starter who could also find some success as a multi-inning reliever if he’s ultimately unable to survive multiple trips through the batting order.
