If Bonaficio is good enough to start some games at third, second, short and center, he could be a 10th regular. A guy who could maybe start 20 games at second and 40 at third against RH pitching, and start against LH at center, short, and left could get 500 plate appearances. Sort of a poor-man's Tony Phillips. I don't know if he is a good enough hitter or good enough at short and center to be considered for such a role, but if he's adequate in the field and better with the stick than Plouffe or Dozier hitting LH and Florimon and Presley hitting RH, then go get him. Adding a base-stealing threat and potential lead-off hitter would be a bonus.
Hoping I don't end up just repeating Stringer here, but some points I'd like to make.
I hope Escobar, still quite young, some talent, a reputation as a quality and versatile glove man who can fill in 4+ positions, kicks it in ST and establishes himself as the next in a long line of quality Twins utility players; re: Newman, Reboulet, Hocking, Punto to just name a few. But while our starting lineup still needs help (as well as health and future promotion) quality teams needs bench strength as well. And the stronger, deeper and more versatile a team's bench, the more that team can adapt to injury, matchups, days off, and late game moves. No matter how well Escobar may perform, there is room for additional help. Now, I don't know that Bonifacio is worth 3M, but he is definitely worth a decent investment, and would be a HUGE plus to the Twins.
He brings solid defense to a number of positions in the OF and Inf, he switch hits, has a decent career OB%, and provides real speed and SB potential on the base baths. He allows you a quality fill in player who can contribute at the top and bottom of the lineup, and helps you play situational baseball.
I firmly believe the Twins need one more quality bat added to the lineup, and unless I am completely missing something here, the addition of Morales as a DH backup 1B makes so much sense, affordable sense, that I find it almost mind boggling its not done yet. No telling what Kubel has left, if anything, Willingham will be gone at the end of the year if not traded before. And to be honest, if he continues to linger on the DL (hopefully not) the Twins wouldn't be devastated by a cut. But the bat and offensive potential of Morales would still be there.
However, there is hardly a single roster I can come up with that doesn't have room for a solid bat/OB guy with defensive flexibility and speed.
