The payroll is too low not to grab another arm or two. Given that injuries happen and Pineda is likely to get hurt some time this season, I think the Twins should heavily consider adding Keuchel, Gio Gonzalez, or even Clay Bucholz as well as Ottavino to round out the bullpen. The lineup looks very solid on paper. Sano and Buxton can get this team to 90 wins alone by each having a 2017-like year. The powerful additions of Schoop, Cron, and Cruz will make the middle of the lineup very dangerous. There's very good potential for this team to have 6-7 20 HR hitters. Add in improvements from Kepler and Castro and you've got a rock solid lineup top to bottom. The only thing that will hold this team back is most likely that 5th starter spot (if no additions are made), and the back of the bullpen, which is relatively unproven. That's why getting Ottavino would be huge.
