Starting Lineup

1 Shed Long 2B
2 J.P. Crawford SS
3 Kyle Seager 3B
4 Tom Murphy C
5 Daniel Vogelbach DH
6 Kyle Lewis RF
7 Jake Fraley LF
8 Evan White 1B
9 Mallex Smith CF


Quick notes: There is a lot of uncertainty with this group, but what do we know is that Evan White is going to play every day at first base after his contract extension. He doesn’t have huge upside but is a fine floor play for a corner infield spot. Dee Gordon shouldn’t be drafted, as it’s Shed Long’s job at second base now. He has sneaky sleeper appeal in a world where sleepers don’t exist anymore. Mitch Haniger could be back this year, but we don’t know when.

Pitching Rotation

1 L
2 Yusei Kikuchi L
3 Justus Sheffield L
4 R
5 R


Quick notes: This is one of the worst rotations in baseball. Marco Gonzales can’t miss any bats, which makes his margin for error very slim. Yusei Kikuchi could have a good sophomore season after disappointing in his first season in the states. His velocity was up in Spring Training. Can Taijuan Walker capture some of the “Prince Taijuan” magic that he had in his first go-around in Seattle?


Quick notes: Your guess is as good as anyone’s here. If there’s one dart throw to take, it’s on Carl Edwards Jr.
