The obvious option: A slugging top prospect
As most Mariners' fans are aware now, Tyler Locklear has made his debut and came up with a big double in his first game. Locklear has been a fast mover through the minor leagues as he dominated pretty much every level. A move from third to first base full-time, allowed Locklear to really focus on the offense and skyrocket through the Mariners system.
Locklear started the year in Double-A Arkansas before being moved to Triple-A Tacoma for just 10 games. I am sure Dipoto would have liked to see more time in Tacoma, but that was cut short due to the France injury news. In 51 games in the minor leagues this year, Locklear slashed .293/.404/.520 with nine home runs. Locklear has shown an advanced approach and looks like someone who can really manage the strike zone.
Locklear is an older prospect and someone that could really provide some offense for the Mariners down the stretch. I really like his approach and ability to limit strikeouts while hitting for some power (a combination that the Mariners have struggled with in recent years). If Locklear can claim the first base position, it would address a lot of concerns for this offense.
