Already reasonable internal options for LF and 2B. Heck, I'd be fine with Travis in LF.
Use the money saved by not signing Melky and by moving Happ and Navarro (for good, cheap RP) to sign Shields for 4 years, and Lowrie for 2.
The bottom 4 of the lineup would be Smoak/Pillar/Valencia, Lowrie, Travis, Pompey which is not bad, and besides the top 5 will create plenty of runs.
SP
Shields
Dickey
Stroman
MB
Hutchison
That's one heck of a good and durable rotation. Remember the days of crossing our fingers on Morrow, McGowan, Johnson, etc
