Seattle Mariners: Predicting the Opening Day 30-man roster
Outfield
The starting outfield to open the season will be Kyle Lewis, Mallex Smith, and Jake Fraley. Smith slumped badly to open the season, hitting a putrid .191 through May. He found his game in the summer months batting .243, with a .723 OPS, and 25 stolen bases from June through August, before finishing the year on a horrendous 8-for-61 slump. To compete, the Mariners need Smith to be the .296/.367/.406/.773 slash line player he was with Tampa Bay in 2018.
Fraley and Lewis, the numbers nine and ten ranked prospects, respectively, both had a cup of coffee in the Majors last year. Lewis was particularly impressive with six home runs in 71 at-bats, including three in his first three MLB games. If he can be a little more selective at the plate, Lewis will become a very dangerous middle of the order batter.
Mitch Haniger starts the season on the 45-day injured list as he recovers from several nasty injuries. Depending on how his rehab goes, Haniger could return in mid-August.
Seattle might add Braden Bishop to the 30-man roster, though he was sent down to Tacoma before the end spring training in March. Additionally, top prospect Jarred Kelenic has a punchers chance to make the team, although he only played 21 games at the end of last season in Double-A ball. Gordon, Lopes, and Moore can all play the outfield.
