In itself it shows value. There is something to be said about playing a bench player or platoon player as a starter. They get exposed and the stat line deteriorates - we saw it with guys like Goins and Barney and something we wanted to avoid but injuries piled up. Up until he was put on the DL Solarte played 111 games out of 116 putting him on pace for 155 games played and 650+ PAs something he has never done before with the exception of 1 season where he hit 152 games but only 571 PAs.
He was pretty much a career NL platoon player coming to the hardest division in the AL East to be a platoon/bench player. Other guys got hurt forcing him into a starting position where he got exposed. Im not going to look to much into his last 4 months because he was put in an unfair position similar to Goins and Barney. They were overused outside of their control.
If he was a 0.9 WAR like he was last season there is value 5.5M. If he is 0.6 WAR there is value at 5.5M. Now if he is truly viewed as a 0-0.5 WAR player then yes there is little to no value to be had and picking up the 5.5M option makes no sense. But it is how you evaluate and value his 2019 contributions and i see him be more than a 0.5 WAR player if used properly.
If all goes well he isnt giving you anything close to 600 PAs and its closer to platoon or bench numbers and he is able to have the expected positive contributors. If he works out then great you have a trade chip, if he doesnt work out then you cut him loose as he is on a 1 year deal and if he works out or doesnt and there is a better kid than him then you have options to move a utility player at the deadline.
I have interest in his depth, versatility, short term deal and my 2019 evaluation of his projected WAR.
