David Lough was a cost controlled outfield option. I get that Bonifacio can play 2b, but with the signing of Infante that will mostly be over. Now I doubt Baltimore would've been as interested in Bonifacio, but they would've been better off moving him based on price. $4 million is a good chunk. Here are what other teams are doing with $10MM for a utility player and a reliever.
ATL ~$10-13MM
C/1B/OF Doumit- $3.33MM
CL Kimbrel- Arb hearing: filed at $9MM/Braves filed at $6.55
CHC ~$9.25MM
OF Schierholz- $2.25
C Kottaras- $1MM
CL Veras- $4MM
2B/SS Barney- $2MM Arb prediction by MLBtraderumors
CIN ~$9.5MM
OF Ludwick- $8.5MM
RP LeCure- $1MM est. MLBTR
CHW ~$5.5MM
OF De Aza- $4.25MM
OF Garcia- $500K pre-arb eligible
CL Jones- $500K pre-arb eligible
OAK ~$10MM
CF Crisp- $7.5MM
OF Reddick- $2.5MM est MLBTR
you get the idea...
These teams also suck ass and taints.
Actually some of those teams like Oakland are really good.
Oakland and Atlanta were the 3rd and 4th best teams in all of baseball last year. Both have young, extremely talented arms across the board, and pretty solid foundations in the field.
Oakland is also known for having one of the healthiest farm systems in baseball year in, year out.
